摘　　要：32种不同产地、不同种类的腐植酸原料中(除上海生化腐植酸外)存在细菌、放线菌、真菌,并且不同腐植酸中微生物的种类、数量不同,但优势菌大致相同;从中分离得到放线菌优势菌4株、真菌优势菌5株,通过菌落形态、菌体形态以及生理生化特征等方面鉴定各菌种。鉴定结果明确,它们属于短小杆菌属(Curtobac-terium Yamadaetc.,1972)、芽孢杆菌属的短小芽孢杆菌(B.pumilus)、灰褐类群阿拉伯链霉菌(S.arabicus Shibataetc.,1957)、青霉属(Penicillium)等。32 kinds of humic acid materials fi＇om different regions except for Shanghai biochemical HA all lied bacteria, actinomyces and fungi, and the species and number of microbe in different humic acid materials were different, but dominent microbe was the same. Meantime, 4 dominant strains of actinomyces, and 5 dominant strains of fungi were isolated. According to colonial morphology, mycelial morphology, and physiological-biochemical characteristics, the microbes were identified as Curtobacterium Yamada, B.pumilus, S.arabicus Shibata, 1957, Penicillium and so on.
