芦苇生物活性组分对小球藻生长的促进效应

利用乙醇从芦苇(Phragmites australis)生物质中提取得到具有生物活性的粗提液,研究了芦苇乙醇粗提液对蛋白核小球藻生物量、叶绿素含量、蛋白质含量的影响.结果表明,芦苇中存在的生物活性组分对蛋白核小球藻的生物量、叶绿素含量、蛋白质含量的提高均具有促进效应,层析中性组分可使小球藻藻密度平均提高0.87倍,最高可提高1.79倍,叶绿素含量及蛋白质含量平均提高0.67倍和0.99倍,最高可提高2.71倍和4.76倍.芦苇中存在的高价值生物活性物质具有很好的开发及应用潜力.

Enhancing effect of Phragmites australis bioactive substances on the growth of Chlorella pyrenoidosa

Bioactive substances were extracted from Phragmites australis by using ethanol and the enhancing effects on biomass, chlorophyll content and protein content of Chlorella pyrenoidosa was studied. The bioactive substances exited in Phragmites australis had strong promoting effect on biomass, chlorophyll content and protein of Chlorella pyrenoidosa. Among neutral fractions of ethanol, the density of Chlorella pyrenoidosa was improved about average of 0.87 times and the maximum increase was 1.79 times. The content of chlorophyll and protein were improved by 0.67 times and 0.99 times averagely, the maximum increase were 2.71 and 4.76 times. The high-value bioactive substance has a good potential for development and application.
