Cultivation of microalgae Chlorella sp. with livestock waste compost as an alternative nutrient source was investigated in this present study. Five culture media with different nutrient concentrations were prepared. The characteristics of algal growth and lipid production were examined. The results showed that the specific growth rate together with biomass and lipid productivities was different among all the cultures. As the initial nutrient concentration decreased, the lipid content of Chlorella sp. increased. The variations in lipid productivity of Chlorella sp. among all the cultures were mainly due to the deviations in biomass productivity. The livestock waste compost medium with 2000mgLCOD provided an optimal nutrient concentration for Chlorella sp. cultivation, where the highest productivities of biomass (288.84mgLday) and lipid (104.89mgLday) were presented.
本研究以畜禽粪便堆肥作为替代营养源来培养小球藻。共制备了五种不同营养浓度的培养基，考察了藻类生长和产脂特性。结果表明，所有培养物的比生长速率、生物量和产率均不同。随着初始营养浓度的降低，小球藻的脂含量增加。所有培养物中小球藻产脂率的变化主要归因于生物量产率的偏差。以 2000mgLCOD 的畜禽粪便堆肥为培养基可为小球藻培养提供最佳的营养浓度，在此条件下，生物量（288.84mgLday）和产脂（104.89mgLday）的最高产率。
