| 摘要: |
| 从海泥、海水及海洋动物中分离到数十株细菌，对其产生活性物质的菌株进一步筛选，得到产蛋白酶、淀粉酶和抑菌活性等生物活性物质的几株海洋细菌，将其中的活性高的四株菌纯化后进行菌种鉴定。通过对革兰氏染色、个体及群体形态观察、糖类发酵、硝酸盐还原等生理特性的研究，依据《伯杰氏细菌鉴定手册》确定它们的分类地位，它们分别应归属为欧文氏菌属(Erwiniasp.)、气单孢菌属(Aeromonassp.)、微球菌属((Micrococoussp.)、和假单孢菌属((Pseudomonassp.)。 |

| Abstract: |
| Several strains were isolated from sea mud in the sea area ofQingdao,Shandong and screened four strains A-21,4-2,5-23 and 7-11producing biology activity substances.More studies have been done and according to bergey’s Manunal of Determinative Bacteriology,8thed,they are identified to be Erwinia sp.,Aeromonas sp.,Micrococuus sp.and Pseudomonas sp.. |
