Abstract

Vermicomposting is a unique technique of converting biowastes into valuable plant growth media (vermifertilizer).While the initial primary decomposition is mainly managed by the microorganisms, the secondary decomposition is managed by the selected species of earthworms (Alexander 1999).The active component involved in the biodegradation and conversion processes during vermicomposting is the resident microbial community, among which bacteria play a very important role. The earthworm species Lampito mauritii was employed for the degradation of Eugenia jambolana. When the worm ingests harmful bacteria, harmful fungi and nematodes, these parasites are destroyed through its digestive process, thus creates soil less harmful to plants and animals. The present investigation was aimed to isolate the bacteria from the compost sample using nutrient agar medium and was identified based on the various biochemical results. Our current research revealed that change in colour of the media proved the presence of Salmonella, Enterobacter, Klebsiella, Escherichia coli, Citrobacter.
