This study sampled honey bees, analyzed gut bacterial diversity via 16S rRNA gene, and screened isolates for cellulolytic, hemicellulolytic, and pectinolytic activities, with subsequent assessment of enzymatic potential. The study reveals that cellulolytic and hemicellulolytic bacterial isolates, mainly from γ-Proteobacteria, Actinobacteria, and Firmicutes, have significant potential for crop residue management. Some genera, like <em>Aneurinibacillus, Bacillus, Clostridium, Enterobacter, Serratia, Stenotrophomonas, Apilactobacillus, Lysinibacillus</em>, and <em>Pseudomonas</em>, are very good at breaking down cellulose and hemicellulase. Notable cellulose-degrading genera include <em>Cedecea</em> (1.390 ± 0.57), <em>Clostridium</em> (1.360 ± 0.86 U/mg), <em>Enterobacter</em> (1.493 ± 1.10 U/mg), <em>Klebsiella</em> (1.380 ± 2.03 U/mg), and <em>Serratia</em> (1.402 ± 0.31 U/mg), while <em>Aneurinibacillus</em> (1.213 ± 1.12 U/mg), <em>Bacillus</em> (3.119 ± 0.55 U/mg), <em>Enterobacter</em> (1.042 ± 0.14 U/mg), <em>Serratia</em> (1.589 ± 0.05 U/mg), and <em>Xanthomonas</em> (1.156 ± 0.08 U/mg) excel in hemicellulase activity. Specific isolates with high cellulolytic and hemicellulolytic activities are identified, highlighting their potential for crop residue management. The research explores gut bacterial compartmentalization in <em>A. mellifera</em>, emphasising gut physiology's role in cellulose and hemicellulose digestion. Pectinolytic activity is observed, particularly in the Bacillaceae clade (3.229 ± 0.02), contributing to understanding the honey bee gut microbiome. The findings offer insights into microbiome diversity and enzymatic capabilities, with implications for biotechnological applications in sustainable crop residue management.

Water played a crucial role in the conversion of cellulose to glucose and 5-HMF by influencing product yields through the interplay of transport properties like heat conduction and viscosity.

A comprehensive understanding of the pathogenicity-associated virulence factors of <em>R. oryzae</em> is essential to develop new antifungals against this fungus.
