germ;microbe

In fermentation experiments with feeding Hyphomicrobium TH205 using methanol as single carbon source the effects of feeding of methanol and adding of Fe~(2+) to the basal medium on the production of PQQ were investigated.

以甲醇为唯一碳源,对生丝微菌TH205进行培养,研究了甲醇流加速度、Fe2+浓度对细胞生长及吡咯喹啉醌(PQQ)表达量的影响。

The Detection of Total Bacterial Number in Mineral Water by Microcolony Technique;

微菌落技术快速定量测定矿泉水中细菌总数的初步研究

Objective To study application of microcolony method to evaluation of germicidal efficacy of chemical disinfectants and to establish new technique for evaluating disinfection efficacy of disinfectants.

目的研究微菌落法在评价化学消毒剂杀菌效果方面的应用,建立评价消毒剂消毒效果新技术。

57 bacterial strains were isolated from microsclerotia of V.

另外从棉花黄萎菌的微菌核际分离到57株细菌,其中30株细菌能显著地抑制棉花黄萎菌微菌核的菌落生长(5个菌株完全抑制微菌核的萌发和生长,15菌株的抑菌率为40%97%)。

Dynamics of microsclerotia of V.

通过在河北省棉田定点连续调查，发现自然病土中的棉花黄萎菌微菌核数量在6月中旬和9月下旬出现两个高峰，同时发现，重病田中的微菌核数显著高于轻病田。

Germination of microsclerotia stored on the soil surface and 10 cm deep in the soil was monitored periodically in this paper.

本文采用诱饵法监测棉花黄萎病圃土表和10cm土层微菌核萌发的同时分离微菌核际微生物。

The total population of microorganisms isolated from microsclerotiniasphere of V.

本试验从棉花黄萎菌微菌核际共分离到微生物7024株，其中拮抗微生物1840株，拮抗微生物比率为26％；细菌5069株，其中拮抗细菌1593株，拮抗菌率为31％；真菌1955株，其中拮抗真菌247株，拮抗真菌率为13％。
