摘要
利用发酵罐对灰树花进行了深层培养。试验结果表明,发酵温度25℃、起始pH6.5、搅拌转速150r/min、接种量10%是最佳的培养条件;pH和通气量对菌丝的生长有极显著的影响,pH在5.50～6.50,通气量体积比(V/V)在1.00～1.40时,菌丝生物量积累最多;通过营养分析,认为可以利用深层培养灰树花进行功能及保健产品的开发。
Grifola frondosa was cultured by fermentor.The experimental results showed the best condition of submerg ed culture was g ained that fermentation temperature was 25℃,the beg inning of pH was 6.5,the rotating speed was 150r /min,and putting in volume was 10%.In addition,pH at 5.50～6.50and the volume ratio of flow of air-compress at 1.00～1.40the biomass of mycelium reached the hig hest level.By nutrition analysis,we consider that Grifola frondosa of submerg ed culture may be used for functional and hyg ienical food.
