摘要:  研究了小球藻细胞活性物质(CGF)的提取方法及其对微生物生长及其生理活动的影响,结果表明:5种不同提取方法的CGF产出率分别为10.6%、18.2%、21.5%、26.6%、28.4%,差异很大,并且其生理活性也不同。添加第4种提取方法的1.0%CGF,24h后计数,啤酒酵母菌数量是对照的14.98倍,乳酸菌数量是对照的2.2倍。CGF具有增加啤酒酵母菌和乳酸菌的细胞分裂速度和促进生长的作用,还可以增加啤酒产气量、调节乳酸杆菌与链球菌的数量比值、延长乳酸制品的保质期,改善品质、增加营养等功能。

Abstract: Both extraction methods of Chlorella cell active substance(Chlorella Groth Factor,CGF)and the effect of CGF physiological activities on microorganisms were studied in this paper.Results showed that the productivities of CGF obtained from five extract methods were 10.6%,18.2%,21.5%,26.6% and 28.4%,respectively.The amount of Saccharomycete and that of Lactobacillus in treatment with addition of 1.0% CGF derived from the fourth extraction method after 24h were 14.98 and 2.2 times respedively to that of control treatment.CGF could not only increase cell fission and growth of Saccharomycete and Lactobacillus and CO2 volume evolved from beer,but also adjust the ratio of Lactobacillus bulgaricus to Streptococcus thermophilus. CGF could also prolong the preserve period of lactic acid products.Meanwhile it could improve nutrition and quality of the products.
