This paper presents the results of the research concerning the influence of two vermicompost granulations, C1<2 mm and C2>2 mm, obtained by sieving, on bacterial and fungal diversity and community structure. Both bacteria and fungi have colonized the vermicompost granulation C2>2 mm with higher counts as compared with C1 fraction. Global microbial activity was expressed by higher values of soil respiration in C2 granulation (123.809 mg CO2 x 100 g-1soil) as compared to 116.833 mg CO2 x 100 g-1soil in C1 granulation. A rich bacteria population with high diversity (H’=2.104 bits) and homogeneity (ε=0.662) was found in C2 granulation. C1 granulation contained a less diverse bacteriobiome, with H’=1.750 bits and ε=0.594. Fungi presented lower biodiversity values than bacteria. Conditions from C1 were more favourable than those from C2 granulation (H’=0,921 bits, ε=0.324 in C1 and H’=0.403 bits, ε=0.089 in C2 fraction). Bacterial microflora from C1 granulation was dominated by Bacillaceae, accompanied by Pseudomonas and actinomycetes and a mix of species (Bacillus, Micrococcus, Pseudomonas, Arthrobacter and actinomycetes) in C2 granulation. In both fractions identified strong cellulolytic species (Fusarium, Scopulariopsis, Penicillium, Cladosporium).
