A biocontrol strain, XF-1, was identified as Bacillus subtilis based on morphology, physiology, biochemistry and biotechnology, which could control clubroot of cruciferous crops effectively.

依据传统形态学、生理生化特征及16S rRNA基因序列，将一株对十字花科根肿病有很好防治效果的菌株XF-1鉴定为枯草芽孢杆菌。

The results show that the dispersity of emulsion is good and the average diameter of particles is about 15 nm. Its bactericidal properties to some bacteria and epiphytes are strong under daylight lamp irradiation. The killing rate to Gram negative bacterium (Staphylococcus aureus and Bacillus subtilis) is 100%, in addition, killing activity of it to Gram positive bacterium is very high. It has a clear antibacterial circle of about 20 mm in diameter toward epiphytes such as Aspergillus niger, Aspergillus flavus and Candida albicans etc.

结果表明，混晶乳液分散性好，粒径约15nm；在普通日光灯照射下，乳液对一些细菌和真菌有很好的抗菌性能：对革兰氏阳性菌（金黄葡萄球菌和枯草芽孢杆菌）的杀灭率达到100%，对革兰氏阴性菌也有很好的杀灭性能，对黑曲霉、黄曲霉和白色念珠菌等真菌产生清晰的抑菌圈，抑菌直径约20mm。

Further more, the antagonistic bacterium can hydrolyze starch and deoxidize nitrate.

初步鉴定该拮抗菌为枯草芽孢杆菌。

In this paper, a new product of Ce/ TiO2 compound antibacterial agent has been made, comparing with naked nano－TiO2, it has better antimicrobial activity against E.coli ,S.aureus and scorch gemmule bacillus in the solar light, increasing the quantity of Ce4+, exhibiting stronger antibacterial property.

制备出稀土铈掺杂锐钛型纳米TiO2复合抗菌功能材料，该抗菌材料与不掺杂的纳米TiO2相比，在可见光下对大肠杆菌、金黄色葡萄球菌、枯草芽孢杆菌的混合菌具有较好的抑菌效果，随着Ce4+的摩尔浓度增加，制备的试样的抗菌能力越强。

The results indicated that when the B.subalis was applied in stimulant aquaculture wastewater,the removing rate of nitrite nitrogen and nitrate nitrogen reached above 99% after four days,pH value obviously decreased,but dissolved oxygen content and S2-content was changed indistinctively.

结果表明，枯草芽孢杆菌可迅速有效的降低水体中的硝酸盐、亚硝酸盐含量，4 d去除率均达99%以上；可有效降低水体的pH值；对水体中溶氧和硫化物含量的影响较小。

The inhibition of micro-organism growth is most pronounced for B. subtilis and A. niger with Fraction AP3 of I. oblongifolia leaves.

对微生物生长的抑制是最具有分数和枯草芽孢杆菌的一 oblongifolia AP3黑曲霉明显叶子。

A substrate concentration of 0.277 kg/L, enzyme/ substrate level of 1408 U/g, temperature of 39.2 ℃, and a hydrolysis time of 4.86 hour were found to be the optimum conditions for high antibacterial activity. Under this condition, the bacteria Escherichia coli, Micrococcus luteus and Bacillus subtilis in the hydrolysates had the inhibitory rate of 71.40%, 56.88%, and 64.54%, respectively.

经Design Expert 7.1.2软件优化，得出胃蛋白酶酶解鲶鱼骨蛋白的最优条件为：底物浓度0.277kg/L，加酶量1408 U/g，水解温度39.2℃，水解时间4.86 h，在此条件下获得的水解物，对大肠杆菌、藤黄微球菌及枯草芽孢杆菌的抑菌率分别为71.40%、56.88%和64.54%。

The result shows that 4.1-6.5 kDa antibacterial substances separated from the crude extract described above could efficiently kill Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis and Micrococcus luteus), but no any activity for Gram--negative bacteria or fungi.

可产生出分子量在4.1-6.5KD之间的抗菌物质，这些抗菌物质对革兰氏阳性菌(金黄色葡萄球菌、藤黄微球菌及枯草芽孢杆菌)有广泛的抗性，而对革兰氏阴性菌和真菌没有抗性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
