By comparing with the curves of classical antibiotics in Doskochilova system, the antibiotic type of fermentation broths was identified. The antimicrobial tests showed, the inhibition rate of alt the twenty strains were considerably and ten of them reached 80% when the fermentation broths was diluted by 10 times. It showed strongest inhibition effect against Erwinia carotorora (17.75 mm). Organize method tests showed that inhibition rate of fermentation broths of the strain HJ1-2 to Sclerotinia sclerotiorum and Botrytis cinerea was 100% and 71.39%, respectively.

By inoculated to tobacco plants, six strains could be re-isolated from the inoculated plants, indicating that they were endophytic bacteria in tobacco. Culture these eight bacteria and Phytophthora parasitica var. nicotianae together, the result showed four endophytic bacteria YN-55, NN-3, YN-4 and YN-10 have the best antagonistic effects.

将这8株内生细菌与烟草黑胫病菌共培，进一步测定拮抗效果结果显示YN-55、NN-3、YN-4和YN-10 4株拮抗效果最好，均在66％以上，并且这4种细菌均对孢子囊的产生有较强的抑制作用，而菌株发酵液对孢子囊的产生的抑制作用不明显。

According to the correlation of the inhibiting concentration to photobacterium and nitrifying bacterium by nitrification substrates and products, the change of luminous intensity of photobacterium can indicate the inhibition from nitrification substrates and products.

根据硝化基质和产物对发光细菌和硝化细菌抑制浓度的相关性，可用发光细菌发光强度的变化指示硝化基质和产物的抑制作用。

The power-time curves of E.coli reacting with Co-SG at different temperature has been determined by microcalorimtric method The multiplication rate constant k, generation time G,bacterial growth inhibition ratio I,total thermogenetic quantity Q, the heat quantity of a single bacterium Q_(0) and the heat quantity of a single bacterium per minute have also been calculated according to the power-time curves.

用微量热法测定了大肠杆菌及其在Co -SG配合物作用下的热谱曲线，计算了速率常数k ，传代时间G、抑制I、总产热量Q、单个细菌的产热量Q0 和每分钟单个细菌的产热量 Q0 ，建立了部分代谢参数之间的关系，探讨了大肠杆菌在不同温度和Co -SG作用下的代谢抑制，发现可用t、tr、tg和 Q0 定量表征在不同温度下大肠杆菌的生长代谢和药物的抗菌活性。

After insecticide carbofuran was applied to soil, the results were compared with control soil: The number of soil aerobic bacteria actinomyces, ammonifying bacteria and mold was strongly restrained, and the restrainratio and pesticide concentration have positive correlation.
