“…Five soybeanassociated bacteria were able to produce chitinase. Previously, it was reported that bacterial isolates hydrolysis area by chitinase secretion, which rapidly acts on colloidal chitin, the only carbon source in the defined Media, confirming bacterial isolates positive for chitinase (Dhole, Phuge et al 2022). These potential bacteria effectively release phosphorus (TCP) and CaCO3 and can produce acid.…”

Microorganisms are critical for the survival of life on Earth, but we know very little about the vast majority ofmicrobes. We studied the culturable soybean root, soil, and nodules microbiome here. Thirty bacterial sampleswere isolated from different localities of soybean crops, including soil, root, and nodules, to assess their abilityfor plant growth promotion. To evaluate the richness and diversity in the root and soil, we performed the mostprobable number (MPN) test. Seven of the bacterial isolates were able to produce cellulase, in which JSW1 andJSW6 were most efficient with 2.56 and 2.05 cellulolytic index. All isolates were able to grow and utilizedpectin, in which JSW2 and JSW3 were most efficient with 0.8 and 0.66 pectinolytic index. Pikovskaya mediamodified with TCP JSW1 and JSW2 showed a 3.0 and 2.33 solubility index, and on CaCO 3 media, the JSW1strain produced a 1.58 solubilization index. All bacterial isolates were phylogenetically identified by sequencingand analyzing the 16S rRNA gene. Under controlled conditions, consortia, Pantoea dispersa, and Rhizobiumsp. isolates considerably improved rice root dry weight by 53%, 75%, and 69% and shoot dry weight by 85%,71%, and 76%. Based on in vitro characterization, the potential bacteria Pantoea dispersa, Pseudomonaskoreensis, and Rhizobium sp. were selected to be evaluated for plant growth, nodulation, and grain yield underfield experiment. Under field conditions, Rhizobium sp and Pseudomonas koreensis were found best as singleinoculation by improving 53% and 49% grain yield, respectively. These potential bacteria could be used asbiofertilizers for soybean crop productivity.

“…Compared with the stages before metamorphosis, the relative abundance of some chitinase‐producing genera, such as Bacillus , Parabacteroides , and Enterococcus , were increased at the stages after metamorphosis completion. Increased relative abundance of chitinase‐producing genera may be attributable to the shift in the main food of O. tormota to chitin‐rich insects (Dhole et al, 2022 ; Shu, Hong, Tang, et al, 2019 ). Previous studies demonstrated that a high abundance of Firmicutes and Bacteroidetes and a high ratio of Firmicutes to Bacteroidetes increased the host's capacity to facilitate absorption or storage for the host (Murphy et al, 2010 ).…”
