摘要
在实验室条件下分离筛选出了3种对草坪草抗逆及抗病性有积极作用的功能性细菌,针对其培养条件及生理学特性进行了研究。结果显示,3菌株利用最好的N源是蛋白胨,牛肉浸膏次之;利用最好的C源是蔗糖,其次为葡萄糖;3菌株在pH值为6～10的范围内均能生长,其中菌株E、F在初始pH值为7 4时生长最佳,菌株H在初始pH值为7 6时生长最佳;最适合3菌株生长的温度范围是30～35℃;3菌株在不同摇床转速和装液量下有不同的生长反应,菌体干质量差异显著。
Three functional bacteria improving disease resistance and adversity resistance of turfgrass were isolated and chosen in the lab. The authors studied their culture conditions and physiological characteristics. The results indicated that the best N source and C source for three bacteria (E, F and H) were peptone and sucrose respectively, beef extract and glucose second; three bacteria could grow at a pH range of 6～10, of which the bacteria E and F grew best when the initial pH value was 7.4 and bacterium H at pH 7.6;the most suitable temperature for them to grow was 30～35 ℃; the dry weight of three bacteria had a significant variance at different shaker speed and different solution amount when cultured in flasks.
