Description
Summary:The use of inoculum containing autochthonous compost microorganisms Bacillus subtilis , B. amyloliquefaciens , and Pseudomonas aeruginosa allowed us to enhance biodegradation of food waste during composting. The survival rate of the introduced microorganisms was verified by classical microbiological and molecular biological methods. The introduction extended the high-temperature stage by 4 days, prevented acidification of the medium, and increased organic matter degradation and moisture evaporation, resulting in a 51% reduction in waste weight in two weeks. Introduced P. aeruginosa appeared to play a key role at the initial stage and was not detected after the temperature increased to 60°C.
