“…Microorganisms exhibit profound tolerance to varied environmental conditions, which makes them ideal entities for biomass degradation. They influence substrate digestibility by initially attacking the material's lignin content, which serves as a potential barrier to cellulose and hemicellulose accessibility [7]. Although the microbial degradation process is often slow, biomass decomposition and nutrient transformation safeguard the natural environment's safety than the chemical, physical, and mechanical treatment strategies [42].…”

“…Fungi roll out their digestibility mechanics by initially attacking and solubilizing lignin chains to release available sugars. The sugars are then hydrolyzed through fermentation processes to produce valuable endproducts [7]. Lignocellulose materials contain iron (II), a substance which enables fungi to produce more peroxidase for the digestibility of lignin [46].…”

Biomass transformation of lignocellulose into compost offers ‘green’ technology for sustainable agricultural development. So far, biomass conversion into compost outweighs fossil resources and other conversational techniques due to the low production cost and environmental pollution reduction. Although composting has aesthetically been resorted to in the digestibility of lignocellulose biomass, its realization has keenly been directed towards adding chemical reagents. However, inclining massively to this treatment instigated research bias as microorganisms’ biomass digestibility remains mostly inadequate. Besides, proliferated growth and activities of microorganisms native to lignocellulose biomass are usually disrupted by chemical treatment. The microbial flora (fungi, bacteria, actinomycetes, archaea, and yeast) involved in composting synthesizes complex biocatalysts (enzymes) that are crucial for solubilizing the biopolymers of lignocellulose materials at a density of 1012 cells g-1. Filamentous fungi are by far excellent degraders of lignocellulose in nature. To adequately ensure sustainable lignocellulose digestibility, microbial engineers must subject research studies to surpassing conditions (feedstock formulation and management processes) suitable for inducing ligninolytic, cellulolytic, and hemicellulolytic enzymes. Hence, the state-of-the-art-method of this review provides insights that relate to mechanisms of microbial reactions on the digestibility of lignocellulose biomass during composting.

“…In terms of environmental and social sustainability, lignocellulosic biomass has great potential for biogas production [14]. Lignocellulosic biomass resources, which consist of both terrestrial plants and waste biomass from the agriculture, agro-food, paper and wood industries, are the largest biomass resources available in the world [16]. The use of lignocellulosic biomass, due to its wide availability and high sugar content, can make a large contribution to meeting the world's energy demand [17,18].…”

Due to the high availability of lignocellulosic biomass, which can be obtained from terrestrial plants, agricultural waste biomass, and the agro-food, paper or wood industries, its use for energy production by methane fermentation is economically and environmentally justified. However, due to their complex structures, lignocellulosic substrates have a low conversion factor to biogas. Therefore, scientists are still working on the development of new methods of the pre-treatment of lignocellulosic materials that will increase the biogas productivity from lignocellulosic biomass. The presented research focuses on the use of a pulsed electric field (PEF) to disintegrate rapeseed straw prior to the methane fermentation process. Scanning electron microscopy observation showed that, in the disintegrated sample, the extent of damage to the plant tissue was more severe than in the control sample. In the sample disintegrated for 7 min, the chemical oxygen demand increased from 4146 ± 75 mg/L to 4920 ± 60 mg/L. The best result was achieved with a 5-min PEF pre-treatment. The methane production reached 290.8 ± 12.1 NmL CH4/g VS, and the biogas production was 478.0 ± 27.5 NmL/g VS; it was 14% and 15% higher, respectively, compared to the control sample.

“…), physical pretreatments (stem explosion, screw extrude, etc.) and biological degradations have been developed to loosen its robust structure and expose more reactive sites to chemical or biological catalysts [3][4][5] . Considering there are plentiful oxygen atoms in the structure of lignocellulose, it is promising to convert cellulosic biomass to oxygen-containing compounds.…”
