Guanosine overproducing mutant was derived from Bacillus subtilis T1001 by using ultraviolet and diethyl sulfate. The mutant was selected directionally and step wisely on the agar plates containing methionine sulfoxide and 8 azaguanine(8 AG).

以枯草芽孢杆菌T1 0 0 1为出发菌株，经紫外线、硫酸二乙酯逐级诱变处理，选育出腺嘌呤缺陷型菌株，然后经蛋氨酸亚砜、8 氮鸟嘌呤( 8 AG)结构类似物平板定向筛选，获得鸟苷高产菌株TA2 0 8。

The inhibitory effect was strongest in King B2 medium, the optimum temperature for the highest antimicrobial activity was 33℃, and the optimal pH9.0. In the antagonistic test of BEB2 to the banana wilt disease, the inhibition was obvious with different in vitro methods, and the control effect of pot experiment was good.

结果发现，香蕉内生拮抗细菌BEB2为枯草芽孢杆菌；不同温度、pH值和培养基下的BEB2发酵液对香蕉枯萎病菌生长的抑制能力具显著差异，在King B2培养基上抑菌作用最强，最适抑菌温度为32 ℃，最适抑菌pH值为9.0。

Bacillus subtilis NCD-2 was an effective bacterial strain to control verticillium wilt of cotton,and could produce antibiotic substances to inhibit the gowth of Verticillium dahliae,the pathogen causing this disease.

枯草芽孢杆菌NCD-2菌株是一株有效防治棉花黄萎病的细菌，它通过产生抑菌物质达到对大丽轮枝菌的抑制作用。

Inoculate portions of Soybean–Casein Digest Medium with a small number (not more than 100 cfu) of the following microorganisms, using a separate portion of medium for each of the following species of microorganism: Aspergillus niger , Bacillus subtilis , and Candida albicans .

在部分大豆-酪蛋白消化物培养基上接种少量（不超过100cfu）下列微生物，每一种微生物均使用单独一部分的培养基：黑曲霉、枯草芽孢杆菌、白色念珠菌。

To explore the effect of coculturing actinomycetes with Bacillus subtilis on the production of bioactive secondary metabolites, we studied the difference between fermentation products of monocultures and the corresponding cocultures of 22 actinomycetes by antimicrobial assay and HPLC-PDA analysis.

为探讨共培养对放线菌产生活性次生代谢产物的影响，结合抗菌活性测定及HPLC-PDA分析，研究了22株放线菌的单培养及其与枯草芽孢杆菌的共培养发酵代谢产物的差异，并选取抗菌活性较强的链霉菌FXJ2.014进一步研究其代谢产物。

摘 要：为探讨共培养对放线菌产生活性次生代谢产物的影响，结合抗菌活性测定及HPLC-PDA分析，研究了22株放线菌的单培养及其与枯草芽孢杆菌的共培养发酵代谢产物的差异，并选取抗菌活性较强的链霉菌FXJ2.014进一步研究其代谢产物。

We selected Streptomyces strain FXJ2.014 with high bioactivity for further analysis and found additional metabolites in fermentation extracts of cocultures of strains FXJ2.014, FXJ1.296 and AS 4.1252 respectively with B. subtilis. Quinomycin A was the main bioactive metabolite produced by the monoculture of strain FXJ2.014, while a new quinomycin-like component named FXJ2.014-HB was produced when strain FXJ2.014 was cocultured with B.

发现FXJ2.014、FXJ1.296、AS 4.1252三株菌与枯草芽孢杆菌共培养时产生其在相同条件下单培养时没有的物质，其中链霉菌FXJ2.014单培养时主要产生醌霉素A，共培养时产物中增加了醌霉素结构类似物FXJ2.014-HB。

5The organic acids in koumiss had apparent inhibitory effect to bacillus subtilis.Lactic acid was important for inhibition, the presence of acetic acid and alcohol improved the inhibitory effect.

酸马奶酒中有机酸对枯草芽胞杆菌有较强的抑菌作用，乳酸起主要作用，醋酸和酒精起增效作用。

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.
