Abstract Purpose The textile industry’s previous chemical use resulted in thousands of practical particulate emissions, such as machine component damage and drainage system blockage, both which have implications. Enzyme-based processing is cost-effective, environmentally friendly, non-hazardous, water-saving. purpose this review to give evidence on the potential activity microbial cellulase industry, mostly confined realm research. Methods This was progressive by considering peer-reviewed papers linked production, its prospective application for industries appraised produced develop assessment. Articles were divided into two categories based results trustworthy educational journals: methods used produce diversity microorganisms through fermentation processes approaches microbes fermentation. Submerged (SMF) solid-state (SSF) techniques are currently being meet industrial demand production bio industry. Results Microbial vital increasing day due no side effect environment human health becoming increasingly important. In conventional processing, gray cloth subjected a series treatments that involved breaking dye molecule’s amino group with Cl − , started accelerated dye(-resistant) bond cracking. A enzyme primarily derived from variety species found various ecological settings biotextile/bio-based product technology future needs applications. Conclusion Cellulase has been advantages cellulose-based textiles, well quality enhancement fabric maintenance over traditional approaches.

Host-Specific Diversity of Culturable Bacteria in the Gut Systems of Fungus-Growing Termites and Their Potential Functions towards Lignocellulose Bioconversion

Insects, Journal Year: 2023, Volume and Issue: 14(4), P. 403 - 403

Published: April 21, 2023

Fungus-growing termites are eusocial insects that represent one of the most efficient and unique systems for lignocellulose bioconversion, evolved from a sophisticated symbiosis with lignocellulolytic fungi gut bacterial communities. Despite plethora information generated during last century, some essential on profiles their contributions to wood digestion in fungus-growing is still inadequate. Hence, using culture-dependent approach, present study aims assess compare diversity lignocellulose-degrading symbionts within three termites: Ancistrotermes pakistanicus, Odontotermes longignathus, Macrotermes sp. A total 32 species, belonging 18 genera 10 different families, were successfully isolated identified Avicel or xylan as sole source carbon. Enterobacteriaceae was dominant family represented by 68.1% bacteria, followed Yersiniaceae (10.6%) Moraxellaceae (9%). Interestingly, five such Enterobacter, Citrobacter, Acinetobacter, Trabulsiella, Kluyvera common among tested termites, while other bacteria demonstrated termite-specific distribution. Further, potential selected strains agricultural waste evaluate capability bioconversion. The highest substrate degradation achieved E. chengduensis MA11 which degraded 45.52% rice straw. All showed endoglucanase, exoglucanase, xylanase activities depicting symbiotic role towards termite gut. above results indicated harbor diverse array differ species may play an inevitable enhance efficacy decomposition. further elaborates our knowledge about termite-bacteria bioconversion could be helpful design future biorefinery.

The objective of this experiment was to investigate the effects Lactobacillus plantarum and molasses on nutrient composition, fermentation quality, bacterial count, aerobic stability, microflora alfalfa silage in sandy grasslands. experimental treatments included control (CK), 10 6 CFU/g (L), 5% (M), + (LM). were determined after 14 days 56 ensiling, respectively. results showed that addition L, M, LM reduced dry matter loss (DM), neutral detergent fiber (NDF), acid (ADF) content, increased water-soluble carbohydrates (WSC) ether extract (EE) compared CK group. Meanwhile, more lactic (LA) accelerated observed, causing pH value drop below 4.5 groups ensiling. promoted bacteria (LAB), inhibited yeast. L significantly content acetic (AA). In terms microflora, made Firmicutes become dominant phylum earlier, while Lactobacillus, Weissella , Pediococcus had a higher abundance. According result Pearson's correlation, there is very significant negative correlation between ( P < 0.01) positive Lactococcus, Enterobacter, Enterococcus Leuconostoc 0.01), which may be by under decreased value. prediction microbial genes indicated M could enhance carbohydrate metabolism membrane transport metabolism, contribute LA production LAB metabolism. general, all improved quality nutrients varying degrees, but considering overall better than L. are recommended used as additives process grasslands improve quality.

Despite recent progress, bacterial degradation of lignin is not completely understood. To address the mechanisms that bacteria from unknown taxonomic groups use to perform lignin-monomer degradation, functional analysis metagenome-assembled genomes soil-derived consortia enriched for microorganisms capable degrading was performed. A total 232 were recovered. After applying quality criteria at least 70 % genome completeness and contamination less than or equal 10 %, 39 obtained. From these, a 14 classification lower levels (i.e., only classified order level higher) chosen further analysis. global potential ecological functions these performed, followed by detailed monolignol pathways. The phylum with highest number Proteobacteria. presented consistent bacteria, like denitrification, different metabolic capacities related sulfur, chlorine, arsenic carbon cycles, in addition plant cell wall components cellulose, hemicellulose, lignin.
