摘要
研究了固氮菌N16不同生长阶段培养液的离心上清液和破碎菌体匀浆对菌株自身生长的影响．结果表明：上清液和菌体匀浆均具有促进N16生长的作用，而且不同生长时期的离心上清液和破碎菌体匀浆对菌株自身生长的促进作用不同；N16菌体在培养过程中产生了某些重要的促进菌株生长的物质，这种现象可能与细菌通过QS系统调节其生理功能有关．
The studies on the effects of Azotobacter N16 culture liquid in different culture period on its growth indicate that upper liquid and serums can accelerate the growth of N16. Moreover, the promoting function is not uniform in the upper liquid and serums in different culture phase. It demonstrates bacteria can secrete some important accelerating growth substance when they grow. It may be associated with adjusting to its physiological function by QS system.
