| 英文摘要 | microalgae represent a potential feedstock for biofuel production. during cultivation under nitrogen-depleted conditions, carbohydrates, rather than neutral lipids, were the major carbon sink of the marine microalga isochrysis zhangjiangensis (haptophyta). carbohydrates reached maximum levels of 21.2 pg cell(-1) on day 5, which was an increase of more than 7-fold from day 1, while neutral lipids simultaneously increased 1.9-fold from 4.0 to 7.6 pg cell(-1) during the ten-day nitrogen-depleted cultivation. the carbohydrate productivity of i. zhangjiangensis was improved by optimization of the nitrate supply mode. the maximum carbohydrate concentration was 0.95 g l-1 under batch cultivation, with an initial nitrogen concentration of 31.0 mg l-1, which was 2.4-fold greater than that achieved under nitrogen-depleted conditions. high performance liquid chromatography (hplc) analysis showed that the accumulated carbohydrate in i. zhangjiangensis was composed of glucose. these results show that i. zhangjiangensis represents an ideal carbohydrate-enriched bioresource for biofuel production.
