Nanocellulose-based biomaterials are at the forefront of biomedicine, presenting innovative solutions to longstanding challenges in tissue engineering and wound repair. These advanced materials demonstrate enhanced mechanical properties and improved biocompatibility while allowing for precise tuning of drug release profiles. Recent progress in the design, fabrication, and characterization of these biomaterials underscores their transformative potential in biomedicine. Researchers are employing strategic methodologies to investigate and characterize the structure and functionality of nanocellulose in tissue engineering and wound repair. In tissue engineering, nanocellulose-based scaffolds offer transformative opportunities to replicate the complexities of native tissues, facilitating the study of drug effects on the metabolism, vascularization, and cellular behavior in engineered liver, adipose, and tumor models. Concurrently, nanocellulose has gained recognition as an advanced wound dressing material, leveraging its ability to deliver therapeutic agents via precise topical, transdermal, and systemic pathways while simultaneously promoting cellular proliferation and tissue regeneration. The inherent transparency of nanocellulose provides a unique advantage, enabling real-time monitoring of wound healing progress. Despite these advancements, significant challenges remain in the large-scale production, reproducibility, and commercial viability of nanocellulose-based biomaterials. This review not only underscores these hurdles but also outlines strategic directions for future research, including the need for bioengineering of nanocellulose-based wound dressings with scalable production and the incorporation of novel functionalities for clinical translation. By addressing these key challenges, nanocellulose has the potential to redefine biomedical material design and offer transformative solutions for unmet clinical needs in tissue engineering and beyond.

Rhizobacteria are important components of soil and directly or indirectly influence the soils quality and plant growth for maintaining adequate plant nutrition and reducing the negative environmental effects of fertilizers. Applying high dose of chemical fertilizers in most of rice fields in the coastal areas could reduce the quality of the soil in the long time. There are few studies addressed to verify the species and functional diversity of cultivable rhizobacteria associated with rice plant in the coastal soils. The objective of the study was to verify the species and functional diversity of rhizobacteria isolated from the coastal soils of two rice production areas of Subang and Indramayu, West Java. Special focus was given to verify phosphate solubilization, nitrogen fixation, IAA and cellulase production of the selected 78 strains of rice rhizobacteria isolated from the coastal paddy field, as well as taxonomical analyses based on 16S rRNA. The results showed that among 78 bacterial isolates from the coastal paddy field, mostly were belonging to the Firmicutes, most of them affiliated with genera Bacillus, 75 strains produced IAA, 32 strains fixed nitrogen, 37 strains solubilized phosphate and 33 strains produced cellulase. Several strains of the rhizobacteria were capable of producing plant growth promoting substances (PGPR), alone or in combination, such as IAA, fixing nitrogen, solubilizing phosphate, and producing cellulase. Taking all of these diverse PGPR characteristics into account, it is clear that the 78 identified isolates have great potential for improving saline soils of the coastal paddy fields in Indonesia.

Palm wine (tuak) is a traditional drink recognized worldwide as the traditional drink of Africa, Southeast Asia, and Central America. The history of alcoholic beverages in Indonesia is from the prehistoric era and is recorded in Borobudur, the largest Buddha temple in Indonesia, built in the eighth century. Although Indonesian society has experienced many social and cultural changes, the tradition of tuak production for daily drinks and ceremonies is strong and widespread and has been introduced as a tourism commodity in regions of Indonesia, especially in Bali. However, there are significant challenges in improving this traditional drink's quality and economic value. In this review, we conducted a desktop study and field survey to learn how tuak is part of Indonesian fermented beverage history, especially in Bali, linked to daily life in most traditional communities and supported by local regulators for the existence of this traditional heritage in society and economy. The nutritional composition of tuak comprises monosaccharides such as glucose and fructose, disaccharides including sucrose and maltose, organic acids, and bioactive compounds encompassing saponins, phenols, terpenoids, alkaloids, and flavonoids. Additionally, tuak contains minerals, alcohols, and essential aromatic compounds. The microorganisms engaged in the fermentation process predominantly comprise ambient air microbes and plant-associated microbes, with a significant prevalence of Saccharomyces cerevisiae, Saccharomyces chevalieri, and Zymomonas mobilis. Additionally, Candida tropicalis yeast is present in the microbial consortium involved in the fermentation. This understanding will provide comprehensive information from a socio-economic perspective to preserve production, celebrate culture and to further develop the value of traditional beverages.

Aim: Landmasses have been continuously modified by tectonic activity, the breakup and collision of landmasses is thought to have generated or suppressed ecological opportunities, altering the rates of speciation, dispersal and extinction. However, the extent to which the signatures of past geological events are retained in modern biodiversity patterns—or obliterated by recent ecological dynamics—remains unresolved. We aim to identify the fingerprint of different scenarios of geological activity on phylogenetic trees and geographic range size distributions.Location: Global.Time period: Geological time.Major taxa studied: Theoretical predictions for any taxa.Methods: We conducted spatially explicit simulations under a neutral model of range evolution, speciation and extinction for three different geological scenarios that differed in their geological histories. We set a limit on the number of populations that locally can coexist, which, along with the geographic boundaries of landmasses, influences the rate of range expansion.Results: Our results demonstrate regions of similar size, age and ecological limits will differ in richness and macroevolutionary patterns based solely on the geological history of landmass breakup and collision even in the absence of species’ ecological differences, that is, neutrality. When landmasses collide, regional richness is higher, lineages exhibit more similar rates of speciation and phylogenetic trees are more balanced than in the geologically static scenario. Stringent local limits to coexistence yield lower regional diversity but in general do not affect our ability to distinguish geological scenarios.Main conclusions: These findings provide an alternative explanation for existence of some hotspots of diversity in areas of high geological activity. Although a limit on the number of coexisting species largely influences regional diversity, its contribution to phylogenetic patterns is lower than variation in per‐capita rates of speciation and extirpation. Importantly, these findings demonstrate the potential for inferring past geological history from distributions of phylogenies and range sizes.

The objective of the study was to isolate fungi from healthy and wilt banana in order to understand their diversity as well as their physiological characters to produce growth hormone and solubilize inorganic phosphate. The fungi were isolated from the leaves, roots, and rhizosphere of the banana. As many 13 fungal isolates were associated with wilt banana, consisted of Fusarium, Trichoderma, Bipolaris, Colletotrichum, Clonostachys, and Talaromyces genus. On the other hand, 12 fungal isolates that belong to 10 genera related to the healthy banana have been isolated, including Trichoderma, Pallidocercospora, Purpureocillium, Pallidocercospora, Mycosphaerella, Chaetomium, Neonectria, Pararamichloridium, Xylaria, and Neocordana. We found that the fungal isolates associated with wilt banana, particularly from the Fusarium genus, actively produced IAA in the presence of exogenous L-Tryptophan have high ability to solubilize insoluble phosphate. The ability of fungal isolates to solubilize insoluble phosphate was correlated with their ability to acidify the medium.

Sorghum has good adaptability to drought stress conditions, but its early vegetative phase and the generative phase are susceptible to stress. Understanding the physiological response of plants under drought and mechanisms regulating drought tolerance in a plant, mediated by arbuscular mycorrhizal fungi (AMF) will be useful in developing a strategy to deal with drought. Here, a pot experiment was used to explore the growth performance, biomass production and physiological responses of two sorghum accessions (4183A and JP-1) inoculated by the AMF under drought stress, as well as the effect of AMF on soil enzyme and microbial stability. Based on growth observations, the AMF inoculation treatment had not significant effect on increasing the drought resistance of the two sorghum accessions. Drought stress decreased the rate of height increment for 4183A, and JP-1 accessions by 37% and 55%, respectively, compared to normal conditions. Shoot dry weight and root dry weight losses were up to 59% and 66%, respectively, compared to well-watered conditions. However, the interaction of AMF and plants to deal with drought can be captured through physiological response, particularly proline accumulation. AMF inoculation in JP-1 accession reduced proline accumulation (99.91 mM/leaf fresh weight) compared to non-AMF inoculated plants (149.86 mM/leaf fresh weight). It can be implied that mycorrhiza can reduce plant stress. In contrast to accession 4183A, there was an increase in the accumulation of proline in plants inoculated with mycorrhiza under drought conditions. Additionally, AMF inoculation improved acid phosphatase activity in the soil and proved crucial for maintaining the stability of the rhizosphere microorganisms under drought-stressed conditions.
