摘　　要：筛选小球藻(Chlorella sp.)的适宜碳源,比较研究小球藻在不同营养方式下的生长情况。结果表明,葡萄糖能显著促进小球藻生长,且小球藻可利用葡萄糖在化能异养、光激活异养、光异养及兼养条件下均可生长,其比生长速率从大到小依次为:兼养、光异养、光激活异养、化能异养及光合自养。兼养培养比生长速率接近于光合自养和光异养培养下的比生长速率之和。The effects of different carbon sources and trophic modes on the growth of Chlorella sp were investigated.The results showed that the optimum carbon source of Chlorella sp.growth was glucose.Chlorella sp.could grow under conditions of chemoheterotrophic,light-activated heterotrophic,photoheterotrophic or mixotrophic modes.But the specific growth rate of Chlorella sp.decreased in the order of mixotrophy,photoheterotrophy,light-activated heterotrophic growth,chemoheterotrophy and photoautotrophy.The specific growth rate of the Chlorella sp.tested in mixotrophic culture was the sum of that under photoautotrophic growth and photoheterotrophic conditions.
