Lasiodiplodan is a β-glucan polymer with different interesting characteristics, including therapeutic properties. It is an extracellular product, which is produced by the filamentous fungus Lasiodiplodia theobromae, using glucose as a substrate. In the present work, the production of lasiodiplodan was studied by the utilization of sugarcane straw as a low-cost carbon source. Glucose-rich sugarcane straw hydrolysate was obtained by a sequential pretreatment with dilute nitric acid (1% v/v) and sodium hydroxide (1% w/v), followed by enzymatic hydrolysis. The fermentation process was conducted by the cultivation of the strain Lasiodiplodia theobromae CCT3966 in sugarcane straw hydrolysate in a shake flask at 28 °C for 114 h. It was found that hydrolysate obtained after enzymatic hydrolysis contained 47.10 gL−1 of glucose. Fermentation experiments of lasiodiplodan synthesis showed that the peak yield and productivity of 0.054 gg−1 glucose consumed and 0.016 gL−1 h−1, respectively, were obtained at 72 h fermentation time. Fungal growth, glucose consumption, and lasiodiplodan production from sugarcane straw hydrolysate presented a similar pattern to kinetic models. The study on the chemical structure of lasiodiplodan produced showed it had a β-glucan construction. The current study revealed that sugarcane straw is a promising substrate for the production of lasiodiplodan.

Pakistan is facing a severe energy crisis due to its heavy dependency on the import of costly fossil fuels, which ultimately leads to expansive electricity generation, a low power supply, and interruptive load shedding. In this regard, the utilization of available renewable energy resources within the country for production of electricity can lessen this energy crisis. Livestock waste/manure is considered the most renewable and abundant material for biogas generation. Pakistan is primarily an agricultural country, and livestock is widely kept by the farming community, in order to meet their needs. According to the 2016–2018 data on the livestock population, poultry held the largest share at 45.8%, followed by buffaloes (20.6%), cattle (12.7%), goats (10.8%), sheep (8.4%), asses (1.3%), camels (0.25%), horses (0.1%), and mules (0.05%). Different animals produce different amounts of manure, based upon their size, weight, age, feed, and type. The most manure is produced by cattle (10–20 kg/day), while poultry produce the least (0.08–0.1 kg/day). Large quantities of livestock manure are produced from each province of Pakistan; Punjab province was the highest contributor (51%) of livestock manure in 2018. The potential livestock manure production in Pakistan was 417.3 million tons (Mt) in 2018, from which 26,871.35 million m3 of biogas could be generated—with a production potential of 492.6 petajoules (PJ) of heat energy and 5521.5 MW of electricity. Due to its favorable conditions for biodigester technologies, and through the appropriate development of anaerobic digestion, the currently prevailing energy crises in Pakistan could be eliminated.

β-Glucans as emerging biopolymer are widely produced by microorganisms in fermentation processes using commercial sugars which make process non-economic. Lignocellulosic substances are inexpensive carbon sources, which could be exploited for sustainable production of β-glucans. In this study, a lignocellulosic material, namely sugarcane straw (SCS) was utilized for the production of extracellular β-glucan by Lasiodiplodia theobromae CCT3966. SCS was subjected to acid and subsequent alkaline pretreatment, followed by enzymatic saccharification using cellulase enzyme. Quantity of 48.65 g/L glucose was released after enzymatic hydrolysis. β-Glucan production was performed by cultivation of fungal strain in SCS hydrolysate at 28 °C and initial culture pH 7. Highest β-glucan yield and productivity of 0.047 gg−1 and 0.014 gL-1h−1, respectively was obtained at 72 h fermentation time. Kinetic study of β-glucan production revealed experimental biosynthesis of β-glucan from SCS hydrolysate followed the trend generated by Logistic and Luedeking-Piret models. Chemical structure of biopolymer produced showed β-glucan constitution.

Catalytic depolymerization of mannan composition of palm kernel cake (PKC) by mannanase was optimized to enhance the release of mannan-derived monomeric sugars for further application in acetone-butanol-ethanol (ABE) fermentation. Efficiency of enzymatic hydrolysis of PKC was studied by evaluating effects of PKC concentration, mannanase loading, hydrolysis pH value, reaction temperature and hydrolysis time on production of fermentable sugars using one-way analysis of variance (ANOVA). The ANOVA results revealed that all factors studied had highly significant effects on total sugar liberated (P<0.01). The optimum conditions for PKC hydrolysis were 20% (w/v) PKC concentration, 5% (w/w) mannanase loading, hydrolysis pH 4.5, 45°C temperature and 72h hydrolysis time. Enzymatic experiments in optimum conditions revealed total fermentable sugars of 71.54±2.54g/L were produced including 67.47±2.51g/L mannose and 2.94±0.03g/L glucose. ABE fermentation of sugar hydrolysate by Clostridium saccharoperbutylacetonicum N1-4 resulted in 3.27±1.003g/L biobutanol.

Hydrogen generation was studied using palm oil mill effluent (POME) as an agro-industrial waste obtained from the palm oil industry. POME was subjected to a dilute acid hydrolysis step by HCl (37% v/v) to release fermentable sugars from cellulosic content. POME hydrolysate obtained was used as a substrate for hydrogen generation. The composition of POME hydrolysate showed glucose and xylose were the main monomeric sugars liberated. Hydrogen production was performed in dark fermentation process, in which the new bacterial strain Clostridium acetobutylicum YM1 was cultivated on POME hydrolysate based on a central composite design (CCD). CCD was constructed by considering three pivotal process variables including incubation temperature, initial pH of culture medium and microbial inoculum size. An empirical model, namely second-order polynomial regression model was generated and adjusted to CCD data. The analysis of empirical model generated showed that the linear and quadratic terms of temperature had a highly significant effect on hydrogen generation (P < 0.01). Furthermore, the quadratic effects of initial pH value of culture medium and inoculum size had a significant effect on hydrogen production at 95% probability level (P < 0.05). The regression model also showed that the interaction effect between temperature and initial pH value of the culture medium on the hydrogen generation was highly significant (P < 0.01). The empirical model suggested that the optimum conditions for hydrogen production were an incubation temperature of 38 °C, initial pH value of 5.85 and inoculum size of 17.61% with predicting the production of a cumulative hydrogen volume of 334.2 ml under optimum conditions. In order to validate the optimum conditions determined, C. acetobutylicum YM1 was cultivated on POME hydrolysate in optimum conditions. Verification test results showed that a cumulative hydrogen volume of 333.5 ml and a hydrogen yield of 108.35 ml H2/g total reducing sugars consumed were produced.

Characterization and production of biosurfactant by a novel bacterial strain isolated from an Iranian oil field was investigated. Biosurfactant has wide applications in oil recovery. A number of ten strains of Bacillus sp. were isolated from oil-contaminated soil samples to study biosurfactant production. Among strains studied, the strain 2IR was selected as a potent biosurfactant-producing bacterium. The identification of the strain 2IR was carried out using scanning electron microscopy, biochemical tests and partial 16 S rRNA gene sequencing with generating a phylogenetic tree. Accordingly, the new strain was identified as Bacillus pumilus 2IR. The biosurfactant produced by the strain 2IR was characterized by high performance liquid chromatography, fourier transform infrared spectroscopy and proton nuclear magnetic resonance test. The tests results characterized the biosurfacant produced as a lipopeptide type. In order to attain the highest surface tension reduction of the lipopeptide biosurfactant, culture medium of the strain 2IR was optimized. Experimental results showed that glucose, crude oil, potassium nitrate and ammonium sulfate were pivotal components of the culture medium for biosurfactant synthesis by B.pumilus 2IR. Similar results revealed that optimum medium compositions were 30.31 g/L glucose, 0.8% (v/v) crude oil, 2.88 g/L potassium nitrate and 2.4 g/L ammonium sulfate. A surface tension value of 30 mN/m was obtained in optimum conditions. This research presents new indigenous strain B. pumilus 2IR for synthesis of biosurfactant usable for possible in situ oil recovery.

Highlights•PKC can be used as substrate for fermentation.•Clostridium acetobutylicum YM1 can be used for hydrogen production.•Temperature, initial pH of culture and inoculum size can affect hydrogen generation.•Optimum biohydrogen production from PKC was determined. AbstractFermentative hydrogen generation was studied using palm kernel cake (PKC) as sustainable cellulosic biomass. PKC was subjected to an acid hydrolysis approach using dilute H2SO4 (7% v/v). PKC hydrolysate obtained was then diluted (70%) and used as a substrate for hydrogen generation. Chemical analysis showed that the main fermentable sugars in diluted PKC hydrolysate were glucose, xylose and mannose with the concentrations of 2.75 g/L, 2.60 g/L and 27.75 g/L, respectively. Hydrogen production was carried out by the cultivation of Clostridium acetobutylicum YM1 on PKC hydrolysate. The effect of incubation temperature, the initial pH of culture medium and microbial inoculum size on hydrogen production was studied using a statistical model. The analysis of the model generated showed that the initial pH value of the culture medium and inoculum size had significant effects on the hydrogen production. The study showed that the optimum conditions for the biohydrogen production were 30.57 °C temperature, pH 5.5 and 20% inoculum size. A verification experiment was performed in the optimum conditions determined. Experimental results of the verification test showed that a cumulative hydrogen volume of 1575 ml/L was generated with consuming 2.75 g/L glucose, 2.20 g/L xylose and 16.31 g/L mannose.

Anaerobic digestion of renewable feedstocks has been known as a prospective technology for the production of clean energy in the form of biogas. Biogas is a sustainable energy carrier which is mainly composed of methane (60%) and carbon dioxide (35–40%). Among the raw substances, organic matters obtained from farm animal waste are pivotal sources for biogas production. In recent years, the number of animal husbandry has drastically grown in Malaysia. Accordingly, a large amount of animal waste including manure, blood and rumen content are produced which provide a tremendous source of biogas generation. This paper presents biogas potential from the organic waste obtained from the farm animals and slaughterhouses in Malaysia. The findings of this study indicated that biogas potential of 4589.49 million m3 year−1 could be produced from animal waste in Malaysia in 2012 which could provide an electricity generation of 8.27×109 kWh year−1.

In this work, hydrolysis of cellulose and hemicellulose content of palm kernel cake (PKC) by different types of hydrolytic enzymes was studied to evaluate monomeric sugars released for production of biobutanol by Clostridium saccharoperbutylacetonicum N1-4 (ATCC 13564) in acetone-butanol-ethanol (ABE) fermentation. Experimental results revealed that when PKC was hydrolyzed by mixed β-glucosidase, cellulase and mannanase, a total simple sugars of 87.81±4.78 g/L were produced, which resulted in 3.75±0.18 g/L butanol and 6.44±0.43 g/L ABE at 168 h fermentation. In order to increase saccharolytic efficiency of enzymatic treatment, PKC was pretreated by liquid hot water before performing enzymatic hydrolysis. Test results showed that total reducing sugars were enhanced to 97.81±1.29 g/L with elevated production of butanol and ABE up to 4.15±1.18 and 7.12±2.06 g/L, respectively with A:B:E ratio of 7:11:1.

This research was performed based on a comparative study on fungal lipid production by a locally isolated strain Cunninghamella bainieri 2A1 in batch culture and repeated-batch culture using a nitrogen-limited medium. Lipid production in the batch culture was conducted to study the effect of different agitation rates on the simultaneous consumption of ammonium tartrate and glucose sources. Lipid production in the repeated-batch culture was studied by considering the effect of harvesting time and harvesting volume of the culture broth on the lipid accumulation. The batch cultivation was carried out in a 500 ml Erlenmeyer flask containing 200 ml of the fresh nitrogen-limited medium. Microbial culture was incubated at 30 °C under different agitation rates of 120, 180 and 250 rpm for 120 h. The repeated-batch culture was performed at three harvesting times of 12, 24 and 48 h using four harvesting cultures of 60%, 70%, 80% and 90%. Experimental results revealed that nitrogen source (ammonium tartrate) was fully utilized by C. bainieri 2A1 within 24 h in all agitation rates tested. It was also observed that a high amount of glucose in culture medium was consumed by C. bainieri 2A1 at 250 rpm agitation speed during the batch fermentation. Similar results showed that the highest lipid concentration of 2.96 g/L was obtained at an agitation rate of 250 rpm at 120 h cultivation time with the maximum lipid productivity of 7.0 × 10−2 mg/ml/h. On the other hand, experimental results showed that the highest lipid concentration produced in the repeated-batch culture was 3.30 g/L at the first cycle of 48 h harvesting time using 70% harvesting volume, while 0.23 g/L gamma-linolenic acid (GLA) was produced at the last cycle of 48 h harvesting time using 80% harvesting volume.

Palm kernel cake (PKC) was used for biobutanol production by Clostridium saccharoperbutylacetonicum N1-4 in acetone-butanol-ethanol (ABE) fermentation. PKC was subjected to acid hydrolysis pretreatment and hydrolysates released were detoxified by XAD-4 resin. The effect of pH, temperature and inoculum size on butanol production was evaluated using an empirical model. Twenty ABE fermentations were run according to an experimental design. Experimental results revealed that XAD-4 resin removed 50% furfural and 77.42% hydroxymethyl furfural. The analysis of the empirical model showed that linear effect of inoculums size with quadratic effect of pH and inoculum size influenced butanol production at 99% probability level (P<0.01). The optimum conditions for butanol production were pH 6.28, temperature of 28°C and inoculum size of 15.9%. ABE fermentation was carried out under optimum conditions which 0.1g/L butanol was obtained. Butanol production was enhanced by diluting PKC hydrolysate up to 70% in which 3.59g/L butanol was produced.

Palm kernel cake (PKC), is an agro-industrial residue created in the palm oil industry, and large quantities of PKC are produced in Malaysia. Sustainable development of the palm oil industry in Malaysia demands an economical technology for the environmentally friendly utilization of PKC in industrial utility systems. This research was carried out to evaluate the use of PKC in the production of cellulase by the cultivation of Aspergillus niger FTCC 5003 in a laboratory packed-bed bioreactor for seven days. A central composite design was used to perform eighteen trials of solid substrate fermentation under selected conditions of incubation temperature, initial moisture content of substrate, and airflow rate. Experimental results showed that a cellulase yield of 244.53 U/g of dry PKC was obtained when 100 g of PKC was hydrolyzed at an incubation temperature of 32.5°C, an initial moisture level of 60%, and an aeration rate of 1.5 L/min/g PKC. An empirical second-order polynomial model was adjusted to the experimental data to evaluate the effects of the studied operating variables on cellulase production. The statistical model revealed that the quadratic term for initial moisture content had a significant effect on the production of cellulase (P < 0.01). The regression model also indicated that the quadratic terms for incubation temperature and interaction effects between initial moisture content and aeration rate significantly influenced cellulase production (P < 0.05). The empirical model determined that the optimum conditions for cellulase production were an incubation temperature of 31.0°C, an initial moisture content of 59.0% and an airflow rate of 1.55 L/min/g PKC.

The production of β-mannanase from palm kernel cake (PKC) as a substrate in solid substrate fermentation (SSF) was studied using a laboratory column bioreactor. The simultaneous effects of three independent variables, namely incubation temperature, initial moisture content of substrate and airflow rate, on β-mannanase production were evaluated by response surface methodology (RSM) on the basis of a central composite face-centered (CCF) design. Eighteen trials were conducted in which Aspergillus niger FTCC 5003 was cultivated on PKC in an aerated column bioreactor for seven days under SSF process. The highest level of β-mannanase (2117.89 U/g) was obtained when SSF process was performed at incubation temperature, initial moisture level and aeration rate of 32.5°C, 60% and 0.5 l/min, respectively. Statistical analysis revealed that the quadratic terms of incubation temperature and initial moisture content had significant effects on the production of β-mannanase (P < 0.01). A similar analysis also demonstrated that the linear effect of initial moisture level and an interaction effect between the initial moisture content and aeration rate significantly influenced the production of β-mannanase (P < 0.01). The statistical model suggested that the optimal conditions for attaining the highest level of β-mannanase were incubation temperature of 32°C, initial moisture level of 59% and aeration rate of 0.5 l/min. A β-mannanase yield of 2231.26 U/g was obtained when SSF process was carried out under the optimal conditions described above.
