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.
