In this study, two isolated strains of nitrogen-fixing bacteria, NF1 (Bacillus subtilis) and NF2 (Azotobacter chroococcum), were added to cow dung compost in individual (NF1, NF2) mixing (NF3; with a ratio 1:1). The results revealed that the total nitrogen levels NF1, NF3 treatments increased by 44.71%, 38.43% 55.35%, respectively, when compared Control (without bacteria addition). Meanwhile, thermophilic period 3 treated groups was prolonged, NH3 N2O emissions significant reduced, especially for NF-3 treatment. Firmicutes preponderant stage, while Chloroflexi, Proteobacteria Bacteroidetes mature stage. These conformed addition composting improved bacterial community structure benefited retention.

The biodegradation of lignocellulosic biomass is a practical and effective method. A random combination six isolates two purchased strains was constructed to obtain LXB, the degradation lignocellulose resulted in 40.6% after 168 hours. total 1872 genes that were differentially expressed involved LXB have been identified Carbohydrate-Active enZYmes Database. Genes encode cellulases hemicellulase abundance, gene encodes displaying highest expression at initial peak stages degradation. Considerable increase Versatile peroxidase coenzyme Alcohol oxidase lignin catabolism. catalyzes breakdown mainly through pathways carbohydrate metabolic pathway, catechol discovered benzoate which participates lignin. Additionally, possesses capability degrade harmful exogenous substances.

It is widely known that the organic farming system, as an important practice for sustainable agriculture, can enhance crop yield and soil properties while restraining pests diseases. This study aims to exhibit contrasting responses of health characteristics conventional coconut in orchards. Twenty-four samples farms were collected from Mo Cay Bac, Nam districts Ben Tre province Vietnam. Soil physical, chemical, microbiological monitored. We noticed significant improvements NH4+, available phosphorus, nitrogen fixing bacteria cellulose decomposing 22.3 mg kg-1, 28.6 5.84 CFU g-1 3.82 38.9 69.0 6.06 4.18 system. Results also indicate promoted dehydrogenase enzyme activity 0.47 0.61 µg TPF hour-1. Conversely, negative rates recorded actinomycetes, fungi, phosphorus solubilizing ranging 4.55, 3.65, 6.45 4.10, 3.46, 5.23 Organic system improved relative abundance beta diversity bacterial community orders such Bacillales, Frankiales, Elsterales, Pseudomonadales, Pedosphaerales beneficial into bulk coconut. Our clearly underlines importance adopting management pursuit a sustainable, environmentally friendly production coconuts Mekong Delta In conclusion, help shape microbial composition recruit coconut, leading quality overall
