Deconstruction of Lignin: From Enzymes to Microorganisms

Molecules, Journal Year: 2021, Volume and Issue: 26(8), P. 2299 - 2299

Published: April 15, 2021

Lignocellulosic residues are low-cost abundant feedstocks that can be used for industrial applications. However, their recalcitrance currently makes lignocellulose use limited. In natural environments, microbial communities completely deconstruct by synergistic action of a set enzymes and proteins. Microbial degradation lignin fungi, important degraders in nature, has been intensively studied. More recently, bacteria have also described as able to break down lignin, central role recycling this plant polymer. Nevertheless, bacterial deconstruction not fully elucidated yet. Direct analysis environmental samples using metagenomics, metatranscriptomics, metaproteomics approaches is powerful strategy describe/discover enzymes, metabolic pathways, microorganisms involved breakdown. Indeed, the these complementary techniques leads better understanding composition, function, dynamics deconstruction. We focus on omics contribution discovery new reactions impact development lignin-based bioprocesses.

Neotropical termite microbiomes as sources of novel plant cell wall degrading enzymes

Scientific Reports, Journal Year: 2020, Volume and Issue: 10(1)

Published: March 2, 2020

In this study, we used shotgun metagenomic sequencing to characterise the microbial metabolic potential for lignocellulose transformation in gut of two colonies Argentine higher termite species with different feeding habits, Cortaritermes fulviceps and Nasutitermes aquilinus. Our goal was assess community compositions capacity, identify genes involved degradation. Individuals from both contained same five dominant bacterial phyla (Spirochaetes, Firmicutes, Proteobacteria, Fibrobacteres Bacteroidetes) although relative abundances. However, detected functional capacity varied, C. (a grass-wood-feeder) microbiome samples containing more related amino acid metabolism, whereas N. aquilinus wood-feeder) were enriched carbohydrate metabolism cellulose The specifically coding debranching- oligosaccharide-degrading enzymes. These findings suggest an association between primary food source predicted categories enzymes present microbiomes each species. To further investigate as sources biotechnologically relevant glycosyl hydrolases, a putative GH10 endo-β-1,4-xylanase, Xyl10E, cloned expressed Escherichia coli. Functional analysis recombinant metagenome-derived enzyme showed high specificity towards beechwood xylan (288.1 IU/mg), optimum activity at 50 °C pH-activity range 5 10. characteristics that Xy110E may be promising candidate development deconstruction applications.

Lower termite (Coptotermes heimi) gut fibrolytic bacterial consortium: Isolation, phylogenetic characterization, fibre degradation potential and in vitro digestibility

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(3), P. e0318090 - e0318090

Published: March 10, 2025

Lower termites produce wide array of fibrolytic enzymes and serves as prospective microbial source for enhancing biodegradability recalcitrant ligno-cellulosic fibrous feeds. The present study was aimed to isolate characterize anaerobic bacteria from gut termite Coptotermes heimi screening promising isolates improve fiber digestibility in ruminants. A total 141 were obtained 97 samples, 24 (TM1 TM24) selected characterized fibrolytic. All obligatory anaerobes catalase negative except, TM8, TM9, TM14 TM22 which facultative positive. Overall enzyme activity highest TM23, TM6 TM22. Highest FPase observed TM5 (12.05 U/ml) while, lowest TM19 (6.41 U/ml). phylogenetic analysis the depicted four major families, i.e., Clostridiales, Bacillales, Lactobacillales Enterobacterales under phyla Firmicutes Proteobacteria . vitro dry matter substrate increased by 9.4 36.0% with inoculation isolated bacterial strains. Among screened isolates, exhibited ability digestibility. findings revealed that - can be used commercial production or rumen biotechnological application utilization feed
