%X The effect of antibiotic biowaste on the microbial communities was investigated during thermophilic composting of antibiotic biowaste from bio-pharmaceutical factory with diary manure. After mixing thoroughly, samples were taken according to the changes of composting temperature. The quantities of all kinds of microorganism were determined by plate counting method. The results showed that the changes of the microbial quantity during composting with penicillin biowaste were different from that during composting with lincomycin biowaste. In penicillin compost the changes of the quantity of bacteria and fungi followed high-low rule and high-low-high rule, respectively. The abundance of actinomycete increased gradually. In lincomycin compost the changes of actinomycete and fungi count followed the high-low-high rule, but the bacteria quantity varied in the order of the low-high-low. Based on the morphology of fungi colony, penicillin and lincomycin biowaste both had adverse influence on the diversity of the microbial community in compost. The bacteria number in lincomycin compost was a tenth less than that in the control at the beginning. The actinomycete number in all treatments was always less obviously than that in the control during composting. The actinomycete number in sample decreased gradually with lincomycin biowaste content increasing at the end of composting. The fall span of fungi number became bigger with the increase of lincomycin biowaste content in thermophilic stage of compost. So the lincomycin biowaste had an inhibition on the growth of bacteria, actinomycetes and fungi at different levels during composting. The decrease of lincomycin residues demonstrated that the composting could make antibiotic biowaste harmless and resource under certain conditions.
