摘要： Volvariella volvacea was grown on cottonseed hull waste compost and divided into high-yield (HBE) and low-yield (LBE) conditions. Gene sequencing was used to examine bacterial and fungal populations during cottonseed husk waste composting. At the end of fermentation, the dominant bacterial genera in the HBE compost were Chelatococcus and Thermobacillus, while Symbiobacterium and Acinetobacter were more abundant in the LBE compost. Ascomycota and Basidiomycota dominated all the composting phases. The Ascomycota genera Colletotrichum, Pichia, Mycothermus, and Thermomyces dominated in phase II of HBE composting. The LBE compost had higher abundances of the Basidiomycota genera Cystofilobasidium and Cryptococcus than the HBE compost. The predicted pathotroph and saprotroph-symbiotroph abundances were more positively linked to HBE composting phase II than to LBE composting. High-biological-efficiency microbial communities are characterized by high pH, carbon, and nitrogen levels. Changes in physiochemical traits, microbial diversity, and metabolism affect the V. volvacea yield.
