【摘要】 从黄石市土壤中分离到一株产碱性蛋白酶的革兰氏阴性杆菌，不产芽抱，具美膜．能在ｐＨ９－１１条件下生长、产酶．产酶最适ｐＨ值为９，最适温度为３７℃，适发酵时间为３６ｈ．发酵产酶量为４５．０Ｕ·ｍＬ－１根据实验结果，该菌株鉴定为毛状假单抱菌Ｐｓｅｕｄｏｍｏｎａｓ　ｌａｓｉａ．更多还原

【Abstract】 A bacillus of negative Gram sinning is isolated ho the soil of Huangshi City,Hubei Province.Thebacillus can peace alkaline protease and has no spore, but has macrocapsule. It can grow and Produce Protease inmedium of pH 9 ~ 11.The best pH for protease production is 9. The best telnperathe is 37 . The optimum femetf take is 36hours. ItS maximum alkaline protease activty is 45. 0 U mL- 1.By results of Gram staining, spore staining, capsule suming, electron microscope obsewing, physioled andbiochehacal tests, the bacillus is denondnated as Pseudomonas lasia.更多还原
