“…Pedobacter is probably the most important bacterial decomposer in the early stages of decomposition in temperate forest ecosystems, as it participates in the degradation of cellulose and hemicellulose [45,46]. A variety of carbohydrates can be fermented by Anaerosporobacter [47]. Our results show that the abundance of Anaerosporobacter and Pedobacter increased, indicating that WJP and CaP treatments may promote cellulose and hemicellulose degradation and change the total carbon content.…”

Background To investigate the effects of phosphorus solubilizing microorganisms and calcium phosphate on the composting of Torreya grandis branches and leaves, as well as to explain the nutritional and metabolic markers related to the composting process. Methods In this study, we employed amplicon sequencing and untargeted metabolomics analysis to examine the interplay among phosphorus (P) components, microbial communities, and metabolites during T. grandis branch and leaf waste composting that underwent treatment with calcium phosphate and phosphate-solubilizing bacteria (Burkholderia). Results The results indicated that Burkholderia inoculation and calcium phosphate treatment affected the phosphorus composition, pH, EC, and nitrogen content. Furthermore, these treatments significantly affected the diversity and structure of bacterial and fungal communities, altering microbial and metabolite interactions. The differential metabolites associated with lipids and organic acids and derivatives treated with calcium phosphate treatment are twice as high as those treated with Burkholderia in both 21d and 42d. The results suggest that calcium phosphate treatment alters the formation of some biological macromolecules. Conclusion These results extend our comprehension of the coupling of matter transformation and community succession in composting with the addition of calcium phosphate and phosphate-solubilizing bacteria.
