【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。更多还原

【Abstract】 32 kinds of humic acid materials from different regions except for Shanghai biochemical HA all lied bacte-ria, 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 identifi ed as Curtobacterium Yamada, B.pumilus, S.arabicus Shibata, 1957, Penicillium and so on.更多还原
