两种氮条件下磷对三角褐指藻产生物柴油的影响
Effect of phosphorus on biodiesel production from Phaeodactylum tricornutum under two nitrogen conditions
摘要
Abstract
In order to study the effect of phosphorus( P) on biodiesel production from Phaeodactylum tricornutum under different nitrogen( N) conditions,Phaeodactylum tricornutum are cultivated in six types of media. The mass concentration of N and P of media,biomass,composition and mass fraction of fatty acids of produced biodiesel during a 7-d cultivation period are measured. The result shows that from P-replete,P-limitation up to P-starvation both in N-replete and N-starvation,the biomass decreases and the mass fraction of fatty acids increases gradually for biodiesel production from Phae-odactylum tricornutum under phosphate deficiency stress. P-replete has no effect on the biodiesel pro-ductivity of P. tricornutum under N-starvation condition because sufficient P cannot make up for reduced biomass resulted from N-starvation. The effect of P on biodiesel production from microalgae may vary with microalgal species and/or strain without N.关键词
