Mechanisms of Enterobacter and Bacillus in promoting aerobic composting and immobilization of Cd in livestock and poultry manure.

ABSTRACT: Aerobic composting of livestock manure concentrates heavy metals like cadmium (Cd), elevating environmental risks after land application. This study screened composite microbial strains for simultaneous promotion of compost maturation and Cd passivation, exploring their mechanisms on the composting process, microbial community succession, and Cd speciation transformation. Three Cd-resistant strains-Enterobacter hormaechei (LB3), Enterobacter cloacae (LB4), and Bacillus velezensis (J-1-2)-were isolated from chicken manure, formulated into two composite inoculants (T1: LB3 + LB4; T2: LB3 + LB4 + J-1-2), and compared with an uninoculated control (CK) during composting. Maturity parameters, Cd species distribution, and microbial community dynamics were monitored. Results showed composite inocu
