1·Screening of Alkaline Protease Producing Alkalophilic Bacillus sp.

产碱性蛋白酶嗜碱芽孢杆菌的筛选及其研究。

2·The objective of this research is to clone the expression element of a major secretory protein gene from Bacillus sp.

本研究的主要目的是克隆芽孢杆菌胞外高丰度蛋白的表达元件，为今后构建表达载体奠定基础。

3·Bean cake was the best nitrogen source, and their optimal mass concentration for Bacillus sp. X18 and X10-1-2 were 4 % and 1 %, respectively.

两株菌的最佳氮源均为豆饼，X18的最佳豆饼质量分数为4%，而X10 - 1 - 2的最佳豆饼质量分数为1%。

4·The hydrophobicities of Bacillus sp. and Pseudomonas sp. were related definitely with the degradation of the organic pollutant in the water environment.

芽孢杆菌和假单胞菌的疏水性与其在水环境中对有机污染物的降解呈一定的相关性。

5·Strains of Bacillus spp. were isolated from 7 soil samples using repeated plate streaking, and 4 strains of them had rivalry ability to Fusarium oxysporum f. sp. cucumerinum.

从不同环境中采集7份土壤样品用于芽孢杆菌的分离纯化，通过多次平板划线分离纯化得到30个菌落形态不同的菌株。

6·The invention is characterized in that the Bacillus sp MK3-1 which has oxidation effect on soluble bivalent manganese is obtained through the separation from soil with the manganese pollution.

本发明的特征是从锰污染的土壤中分离得到一株对可溶二价锰有 氧化作用的芽胞杆菌MK3-1。
