“…The pretreated SBB can undergo enzymatic and microbial biomass conversion, leading to the breakdown of its biomass into various pentose and hexose sugars, such as glucose, galactose, xylose, and arabinose (Dutta et al., 2023). Biotransformation using sugars produced via the enzymatic digestion of SBB has gained significant attention in recent years, particularly in the production of SCP, bioenergy, and other products.…”

With rapid growth of global population, meeting the increasing demand for food has become a significant challenge. This challenge is further compounded by limited arable land and the necessity to address the nutritional needs of both humans and animals. However, the utilization of straw biomass, which is readily available as an agricultural by‐product, presents a sustainable solution to this problem. Microbial fermentation has emerged as a highly effective method for converting non‐food biomass into protein, particularly known as single‐cell protein (SCP). Compared to traditional protein sources, SCP production through microbial fermentation is rapid and efficient, and requires minimal land resources. This review provides a comprehensive review of the research advancements in SCP from agricultural biomass, including pretreatment methods, microbial strains, and fermentation processes involved in the bioconversion of straw biomass. Due to the complexity of straw‐based biomass (SBB), it is essential to customize industrial strains and optimize the fermentation process to achieve the highest protein yield and productivity. Additionally, improving the compatibility between tailored processes and cost‐effective industrial strains can lead to the production of protein substitutes that are not only highly nutritious but also economically viable. Hence, the application of SCP derived from SBB presents a dual solution by reducing the need for managing agricultural residues and providing a sustainable source of protein. However, the production of SCP from SBB also has some limitations, such as protein‐synthesis efficiency, production cost, and difficulty to scale‐up the production process. In the future, there is great potential for significant advancements in the targeted conversion of SBB into protein by customizing high‐performance microbial strains. Several sensor and machine learning technologies will predict and monitor real‐time dynamic changes in the fermentation process of SBB, offering an opportunity to improve the production of sustainable SCP in an environmentally friendly and precise manner.

“…This solar energy can be converted into other forms of consumable energy later. Biomass is able to produce electricity, heat, liquid fuels, and gaseous fuels (biogas) and can have various useful chemical applications (Dutta et al, 2023;Periyasamy et al, 2023;Kumar & Agrawal, 2020;Jahanbakhshi & Salehi, 2019).…”

Biomass energy is a type of renewable energy and animal waste is one of the main resources for its production. Anaerobic digestion is a method for biological treatment of organic waste, which nowadays plays an important role in refining and reusing wet and degradable waste materials due to the production of environmentally friendly materials and energy recovery. The process of anaerobic digestion takes place in oxygen-free conditions inside reactors called anaerobic digesters and produces a substance called biogas. The purpose of this study is to investigate the effect of raw material type (cow and chicken manure) and the type of reactor (digester) on the biogas produced by measuring the amount of methane in the product. Three types of digester (metal, simple PVC and PVC with leachate rotation) with the same volume (10 Liter) were prepared. Equipment was installed on the digesters to measure the pH and volume of produced gas. The experiments were carried out in controlled temperature conditions (28–30 ºC) and in two stages. The first experiment was to load the digesters with cow excrement and the second experiment was to load the digesters with chicken excrement. In both experiments, the digesters were fed with 1.5 kg of animal manure and water with a ratio of 1:1. During a period of 60 days, the volume of biogas and methane produced was measured and recorded. The results showed that the amount of biogas produced from chicken waste is more than the amount obtained from cow waste. However, the amount of methane produced using cow excrement was more than that of chicken excrement. Also, the performance of PVC digester with leachate rotation was better than the other two digesters, which could be due to the mixing of raw materials in this type of digester.

“…The overexploitation of global non-renewable resources, particularly fossil fuels, has caused negative effects on the natural ecosystems that, consequently, disturb the quality of human health (Mujtaba et al 2023 ). The valorization of the lignocellulosic biomass as a sustainable alternative to mitigate environmental and health issues and reduce the dependence on carbon fossil resources has gained the attention of both the scientific community and the industry (Dutta et al 2022 ; Kukkar et al 2022 ; Mujtaba et al 2023 ).…”

“…Lignocellulosic biomass has proven to be the most abundant and renewable raw material on Earth. It arises from diverse sources, such as agricultural and forestry residues, dedicated energy crops, and organic fractions from recycling stations (Dutta et al 2022 ; Kukkar et al 2022 ; Mujtaba et al 2023 ). This type of materials are great feedstocks to produce valuable compounds, namely biofuels, biochemicals, bioplastics, among others (Dutta et al 2022 ).…”

Xylanases are key biocatalysts in the degradation of the β‐1,4‐glycosidic linkages in the xylan backbone of hemicellulose. These enzymes are potentially applied in a wide range of bioprocessing industries under harsh conditions. Metagenomics has emerged as powerful tools for the bioprospection and discovery of interesting bioactive molecules from extreme ecosystems with unique features, such as high temperatures. In this study, an innovative combination of function-driven screening of a compost metagenomic library and automatic extraction of halo areas with in-house MATLAB functions resulted in the identification of a promising clone with xylanase activity (LP4). The LP4 clone proved to be an effective xylanase producer under submerged fermentation conditions. Sequence and phylogenetic analyses revealed that the xylanase, Xyl4, corresponded to an endo-1,4-β-xylanase belonging to glycosyl hydrolase family 10 (GH10). When xyl4 was expressed in Escherichia coli BL21(DE3), the enzyme activity increased about 2-fold compared to the LP4 clone. To get insight on the interaction of the enzyme with the substrate and establish possible strategies to improve its activity, the structure of Xyl4 was predicted, refined, and docked with xylohexaose. Our data unveiled, for the first time, the relevance of the amino acids Glu133 and Glu238 for catalysis, and a close inspection of the catalytic site suggested that the replacement of Phe316 by a bulkier Trp may improve Xyl4 activity. Our current findings contribute to enhancing the catalytic performance of Xyl4 towards industrial applications. Key points • A GH10 endo-1,4-β-xylanase (Xyl4) was isolated from a compost metagenomic library • MATLAB’s in-house functions were developed to identify the xylanase-producing clones • Computational analysis showed that Glu133 and Glu238 are crucial residues for catalysis Graphical abstract
