Efficient Lignin Decomposing Microbial Consortium to Hasten Rice-Straw Composting with Moderate GHGs Fluxes

We hypothesized that lignin decomposition microbial consortium would make rice-straw faster as straw contain around 15–24% lignin. In this study, we isolated aerobic degrading microbes from four natural sources and based on their ability towards degradation strains combination (2 bacteria (LB 8, LB 18) 2 fungi (LF 3, LF 9) were selected for rice decomposition. The greenhouse gases emission, enzymatic activities (β-glucosidase, cellulase, laccase), reduction in content, weight loss carbon nitrogen ratio (C:N) quantified during the process of β-glucosidase, cellulase laccase higher compost where 18 + 3 was applied compared to others. content also decreased (8.9–9.5 6.6–7.9%) gradually initial 28th days composting under 3. found decomposed relatively than other strains/consortium tested indicated by lowering C:N lignin, hemicellulose, cellulose contents 60, 19.2, 41.5 10.3%, respectively at day values. However, higher, methane dioxide fluxes observed (1.36 200.7 mg m−2 h−1) with no significant trend nitrous oxide fluxes. Further, identified could be in-situ proper moisture management evaluate its potential field condition. Therefore, conclude use decomposing has hasten large scale.Graphic abstract
