Several research studies have focused on microbiological studies of waste in the case of composts and vermicompost. However, until now systematic and functional analyses of the microbial groups of separately decaying green household waste in the natural environment have been unsatisfactory. Therefore, in our previous studies, the systematic and functional microbial groups associated with decaying pomegranate and banana wastes in water and soil have been well characterized. The quantitative results of the systematic groups (bacteria, yeasts, molds and actinomycetes) have shown that the values of these microbial groups were generally lower in banana waste than in pomegranate waste, and higher in soil decay than in water decay. The quantitative results of the functional groups have shown that amylolytics were highest (6.4 107 cells/g dw) after 15 days, nitrifiers were most pronounced (8.56 106 cells/g dw) after 30 days, denitrifiers were important (3.63 105 cells/g dw) after 60 days, aerobic nitrogen fixers were highest (3.78 109 cells/g dw) after 75 days, and ammonifiers were most noticeable (3.9 108 cells/g dw) after 90 days of decay.
