黑钙土细菌种群组成特征

Study on Composition Features of Bacteria in Chernozem

报道了采自吉林省农安县新刘家镇刘家村三社黑钙土中的细菌种群组成:(枯草芽孢杆菌、蕈状芽孢杆菌、类产碱假单胞、荧光假单胞菌变种Ⅰ、施氏假单胞菌、放射形土壤杆菌变种Ⅰ、放射形土壤杆菌变种Ⅱ、约氏不动杆菌、乙酸钙不动杆菌、喜盐微球菌、产黄纤维单胞菌、粪肥纤维单胞菌、柠檬色节杆菌、球形节杆菌、黄黄色杆菌等)及其鉴别特征,并根据其在土壤中的数量组成和分离出现率确定了柠檬色节杆菌、球形节杆菌、放射形土壤杆菌变种Ⅰ、类产碱假单胞、荧光假单胞菌变种Ⅰ、枯草芽孢杆菌、蕈状芽孢杆菌、粪肥纤维单胞菌为黑钙土的优势细菌种群。

Twenty species： Bacillus subtilis, B. mycoides, Pseudomonas pseudoalaligenes, P. fluorescens var. Ⅰ , P. stutzeri , Agrobacterium radiobacter var. Ⅰ ; A . radiobacter var. Ⅱ , Acinetobacter johnsonii , Ac. calcoaceticus, Micrococcus halobius, CeUulomonas flavigena, C. fimi ; Arthrobacter globiformis ; A. citreus and Xanthobacter flavus were reported in this paper. According to the amount and the rate of isolation Arthrobacter globiformis, A. citreus , Agrobacterium radiobacter var. Ⅰ , Pseudomonas pseudoalaligenes ; P. fluorescens var. Ⅰ ; Bacillus subtilis ; B. mycoides ; CeUulomonas fimi were dominant species.
