Agriculture is essential for nutrition and the global economy, becoming increasingly important due to population growth and higher food demand. This situation boosts interest in creating bioproducts that enhance productivity sustainably while reducing environmental issues and strain on natural resources. Bioinoculants are important innovations that use beneficial microorganisms to boost crop growth and resilience. They enhance the interaction between soil and plants by solubilizing essential nutrients and producing phytohormones. This not only boosts agricultural productivity but also promotes environmentally sustainable practices by decreasing reliance on chemical fertilizers. Considering the relevance of this subject to advances in agro-industrial biotechnology, this review analyzes recent studies and patent advances on the production and use of bioinoculants, as well as their integration into agricultural practices and plant development. It also explores the dynamics of production and downstream processes on an industrial scale, regulations in different countries, and growing market demands, which is an important feature of this review. Furthermore, future perspectives for the application of bioinoculants in agro-industrial biotechnology are discussed, emphasizing the critical role that these biological agents play in advancing agricultural sustainability.

Renewable energy sources, such as biofuels, represent promising alternatives to reduce dependence on fossil fuels and mitigate climate change. Their production through enzymatic hydrolysis has gained relevance by converting agro-industrial waste into fermentable sugars and residual oils, which are essential for the generation of bioethanol and biodiesel. The fungus Aspergillus stands out as a key source of enzymes, including cellulases, xylanases, amylases, and lipases, which are crucial for the breakdown of biomass and oils to produce bioethanol and fatty acid methyl esters (FAME). This review examines the current state of these technologies, highlighting the significance of Aspergillus in the conversion of energy-rich waste materials. While the process holds significant potential, it faces challenges such as the high costs associated with enzymatic production and final processing stages. Agro-industrial waste is proposed as an energy resource to support a circular economy, thereby eliminating reliance on non-renewable resources in these processes. Furthermore, advanced pretreatment technologies—including biological, physical, and physicochemical methods, as well as the use of ionic liquids—are explored to enhance process efficiency. Innovative technologies, such as genetic engineering of Aspergillus strains and enzyme encapsulation, promise to optimize sustainable biofuel production by addressing key challenges and advancing this technology towards large-scale implementation.

It is widely known that mushrooms present several properties with applications in the medicinal and pharmaceutical sectors, including antimicrobial, immunomodulatory, antioxidant, hypotensive, neuroprotective, and anti-inflammatory activities. This article aims to review examples of the bioactive metabolites responsible for those activities, such as polysaccharides, phenols and polyphenols, terpenes, peptides, alkaloids, and steroids, which are produced by several relevant mushroom species. It also discusses their production through solid-state fermentation and submerged fermentation, as well as the processes of obtention of mushroom bioactive extracts and considerations on their stability aiming industrial applications. In addition, the article examines the patent landscape surrounding mushroom-derived bioactives, shedding light on the intellectual property history and innovations driving this field forward. Examples of recently deposited patents in the field are highlighted, as well as the main depositors. China and the United States are the major depositor countries in this field (52% and 35% of patents, respectively), and the principal compounds on the patents are polysaccharides and alkaloids. The article also provides insights into the current market landscape, showcasing mushroom-derived products in the pharmaceutical field available to consumers. From dietary supplements to skincare formulations, the market offerings reflect the growing interest in harnessing the health benefits of mushroom bioactives.

The biodiversity of marine and coastal ecosystems is constantly threatened by pollutants from a diversity of human activities. The polycyclic aromatic hydrocarbons (PAHs) are a class of pollutants widely released and deposited in these environments, leading to several impacts on the community of organisms that integrate these ecosystems. As lipophilic compounds, PAHs become bioavailable to organisms and can enter the trophic chain, leading to physiological changes and affecting different levels of biological organization. Several studies demonstrate that PAHs act as endocrine disruptors in marine fish, interfering with endocrine signaling through hormonal disturbances and, consequently, causing inhibition or overexpression of genes, enzymes, and proteins that are essential for reproduction success. These changes, in turn, can lead to population decline and cause immeasurable ecosystem damage. This review synthesizes studies published mainly between 2015 and 2025, aiming to critically present research that identifies different endocrine-reproductive changes in marine fish species exposed to PAHs in contaminated sites, highlighting the involved cellular mechanisms. Finally, we provide a survey of patents developed to identify PAHs in aquatic environments and how these techniques can be used in marine biomonitoring to evaluate water quality and the risk of exposure to biota and human populations.

The market for microbial gums such as xanthan, gellan, dextran, and curdlan is continuously expanding, driven by their increasing application in various industries including petroleum, pharmaceuticals, cosmetics, and food, with the latter accounting for approximately 50% of global usage. To meet the growing demand and improve sustainability, there is a need to enhance production efficiency and reduce costs. This article addresses these issues by examining recent advancements and emerging trends in microbial gum production and application. By highlighting patented technologies and innovative approaches, the article aims to provide a comprehensive understanding of how the industry can achieve higher yields and economic viability. Despite being produced by different microorganisms, these gums are synthesized under similar conditions, such as pH, temperature, and medium composition. The purification or downstream processes for these gums are also comparable, primarily involving solvent precipitation, centrifugation for separation, and drying. Significant advances in gum production include genetic improvement of microbial strains to improve biopolymer performance. Additionally, alternative media are being explored, either by optimizing nutrient availability or deprivation, or by using agroindustrial by-products to reduce production costs. Engineering improvements are another strategy: bioreactor characteristics, fermentation conditions and modes of operation, and advances in downstream process are highlighted. Furthermore, the text explores emerging trends in the application of microbial gums in the food sector. Microbial gums applications are not limited to their traditional action as emulsifiers and stabilizers, but expands to new uses in biodegradable packaging films and as antioxidant and prebiotic food ingredient.
