This research focused on the use of composite microbial preparations, derived from the complex strains (Alcaligenes aquatilis, Rhodococcus jostii, Alcaligenes faecalis, Lysinibacillus varians, Bacillus megaterium, Bacillus velezensis, Bacillus subtilis, Glutamicibacter arilaitensis, Cupriavidus nectar, Bacillus licheniformis, Pediococcus acidilactici and Bacillus sp. SinR4), in compost production in cold regions. These strains, isolated from livestock manure, compost, and soil, were examined for their heat stress resistance and antagonism. About 30 days after putting microorganisms in the compost (T), It showed that the treatment group had a higher average temperature than the control, with the peaks being 60.1°C and 58.9°C, respectively. Moreover, the treatment group had less production of gases like ammonia, amine, and hydrogen sulfide, and a shorter deodorization time than the control group. The results suggest that the use of such composite microorganisms can enhance compost production by promoting temperature increase, reducing odorous gas production, and inhibiting thermal stress.
