Some essential information on gut bacterial profiles and their unique contributions to food digestion in wood-feeding termites (WFT) soil-feeding (SFT) is still inadequate. The feeding type of hypothesized influence composition its functionality degrading lignocellulose or other organic chemicals. This could potentially provide alternative approaches for the degradation some recalcitrant environmental Therefore, metagenomic analysis can be employed examine functional symbionts WFT SFT. Based 16S rRNA gene sequences WFT, Microcerotermes sp., SFT, Pericapritermes nitobei , findings revealed a total 26 major phyla, with 18 phyla commonly represented both termites, albeit varying abundances. Spirochaetes dominated sp. at 55%, followed by Fibrobacters, while Firmicutes bacteria P. 95%, Actinobacteria coming second 2%. Furthermore, Shannon phylogenetic tree diversity indices, as well observed operational taxonomic units Chao 1 richness were all found higher than SFT deduced from alpha analysis. principal coordinate analysis, exhibited significant distance dissimilarity between symbionts. results showed that differed significantly Tax4Fun evaluated functions, revealing predominance carbohydrate metabolism, amino acid metabolism energy termites. implicated inhabiting guts actively involved compounds.

Lignocellulosic biomass (LCB) in the form of agricultural, forestry, and agro-industrial wastes is globally generated large volumes every year. The chemical components LCB render them a substrate valuable for biofuel production. It hard to dissolve resources production because lignin, cellulose, hemicellulose parts stick together rigidly. This makes structure complex, hierarchical, resistant. Owing these restrictions, junk waste has recently become significant worldwide environmental problem resulting from inefficient disposal techniques increased persistence. In addition, burning waste, such as paddy straws, widespread practice that causes considerable air pollution endangers environment human existence. Besides increasing industrialization resulted billions tons dyeing wastewater several industries, including textiles, pharmaceuticals, tanneries, food processing units. massive use synthetic dyes various industries can be detrimental due recalcitrant aromatic dyes, similar polymeric phenol lignin structure, their persistent color. Synthetic have been described possessing carcinogenic toxic properties could harmful public health. Environmental emanating great concern should carefully handled mitigate its catastrophic effects. An effective strategy curtail problems learn analogous systems nature, termites, where woody lignocellulose digested by wood-feeding termites humus-recalcitrant compounds are decomposed soil-feeding termites. termite gut system acts unique bioresource consisting distinct bacterial species valued lignocellulosic materials degradation which integrated into modern biorefineries bioremediation applications treatment wastewaters help resolve issues arising wastewaters. review paper provides new efficient management pollutants exploring potential application bacteria biorefinery processing.
