Responses in growth, lipid accumulation, and fatty acid composition of four oleaginous microalgae to different nitrogen sources and concentrations
摘要
Abstract
Nitrogen deficiency is an effective strategy for enhancing lipid production in microalgae. Close relationships exist among lipid production
microalgal species
and nitrogen sources. We report growth
lipid accumulation
and fatty acid composition in four microalgae (Chlorococcum ellipsoideum UTEX972
Chlorococcum nivale LB2225
Chlorococcum tatrense UTEX2227
and Scenedesmus deserticola JNU19) under nitrate- and urea-nitrogen deficiencies. We found three patterns of response to nitrogen deficiency: Type-A (decrease in biomass and increase in lipid content)
Type-B (reduction in both biomass and lipid content)
and Type-C (enhancement of both biomass and lipid content). Type-C microalgae are potential candidates for large-scale oil production. Chlorococcum ellipsoideum
for example
exhibited a neutral lipid production of up to 239.6 mg/(L·d) under urea-nitrogen deficiency. In addition
nitrogen deficiency showed only a slight influence on lipid fractions and fatty acid composition. Our study provides useful information for further screening hyper-lipid microalgal strains for biofuel production.
