【摘要】 目的　探讨培养基成分对乳酸芽孢杆菌BacillusspWTFY芽孢形成的影响。 方法　分别改变碳源、氮源、无机盐的浓度及种类 ,观察芽孢的形成情况。结果　当碳源 (葡萄糖 )浓度超过 0 .1 %时 ,菌体无芽孢形成 ,其他如氮源、无机盐 (磷、镁 )的浓度及种类也有一定的影响 ,但影响并不十分显著。结论　碳源浓度是影响乳酸芽孢杆菌 BacillusspWTFY芽孢形成的关键因素更多还原

【Abstract】 Objective Study the relationship between the component of medium and spore formation of Bacillus sp WTFY. Methods Alter the carbon source?nitrogen source?inorganic concentration and kinds in turns, observe the sporulation circumstances of Bacillus sp WTFY Results When glucose concentration was higher over 0.1%, spore did not emerge;Nitrogen source?phosphorus?magnesiumions concentration and kinds have some degree influence,but not significantly.Conclusion Carbon source concentration is a key factor that influence spore formation.更多还原
