摘要 從酒窖分 離到一株編號為8502-3的細菌. 該菌株能以甲醇為唯一碳 源和能源生長, 並累積PHB顆粒. 能以乙醇, 甲胺, 二甲 胺, 三甲胺, 甲酸鹽, 乙醇酸, 乙酸鹽, 乙醛酸, 乙醛和 蛋白腖為唯一碳源生長. 有氧時, 最適氮源為銨鹽和硝酸 鹽. 厭氧條件下, 能以硝酸鹽作為氮源生長. 最適生長 pH和溫度分別為7.2和35.0'C. DNA中G+C含量為65.5mol%. 它具側生單鞭毛,在2.5%氯化鈉中不能生長, 不能用丙三 醇, 丁酸鈉和天冬氨酸作為碳源生長. 經鑑定認為此 菌株為一新亞種, 命名為查氏生絲微菌成都亞種 (Hyphomicrobium zavarzinii subsp. cheagduense subsp. nov.).
Abstract A strain of actinomycete No.14.83102, isolated from a soil sample from rice field in east suburb of Nanchang city, Jiangxi province, China,producing numerous swellen substrate spores. These spores are spherical, ovoid, ellipsoidal or club in shape with diameter of about 2-2.4 micrometer, stalked or sessile,single or 2 to several inshrot chain, spore surface smooth. Aerial spores are formed on 2-6 coils spiral streptomyce-like spore chain of aerial mycelium.These spores are ellipsoidal or cylindrical withdiameter of about 0.5-0.8 micrometer, spore surface smooth Its cell wall chemical composition is of type 1, containsLL-DAP and glycine. In addition, it contains a littele leucine. There is no characterisic sugar from whole cell analysis.
According to characteristics mentioned above, the strain No.14.83102 considered belonging to the genus Microstreptospora. Its characteristicsdiffer from that of the species Microstreptospora cinerea. So the strain No.14.83102 considered as a new species of the genus and the nameMicrostreptospora nanchangensis sp. nov. has been proposed.
