培养基、光照强度和初始氮浓度对克里藻生长 及生物活性代谢产物积累的影响Effects of media, light intensity and initial nitrogen concentration on the growth and bioactive metabolites accumulation of Klebsormidium sp. JNU41
为利用克里藻JNU41高效生产油脂、亚油酸和叶黄素等重要代谢产物,对其进行培养条件的优化及代谢产物积累的评估。采用改良的BG-11(mBG-11)和BBM(mBBM)培养基,设置3组光照强度〔单侧100 μmol/(m2·s)、单侧300 μmol/(m2·s)和双侧300 μmol/(m2·s)〕和6种初始氮浓度(3、6、9、12、15、18 mmol/L)对克里藻JNU41进行培养,并测定其生长曲线、生化组成、总脂产率、脂肪酸组成及叶黄素含量。结果表明:克里藻JNU41在mBBM培养基、双侧光照强度300 μmol/(m2·s)、初始氮浓度6 mmol/L条件下,生物量和总脂产率最高,分别...
