In our study we focused our work on the treatment of food waste by vermicomposting in the presence of Eisenia fetida. Furthermore, we have used 4 types of beddings for earthworms: dead chestnut leaves, vermiculite, soil, and commercial vermicompost. During this experiment we followed changes of catabolic capacity (biolog ecoplate) and biomass (SIR) of microflora we have also made the counting of the number of individuals of Eisenia fetida. From different stages of maturation. We found that the Eisenia fetida decreases strongly the substrate induced respiration (SIR) in all types of vermibeds used, moreover the the biolog ecoplate showed an increase of substrates utilization patterns , accept in amino acids and amines utilization in treatment witch we used vermiculite, the growth and fecundity of earthworms were higher in microcosms with vermiculite and vermicompost.
