摘要

采用BBM培养基,以雨生血球藻(Haematococcus pluvialis CG-11)为研究材料,通过测定细胞生长速率、叶绿素和类胡萝卜素含量、生物量和虾青素含量,探讨氮、磷营养对雨生血球藻营养细胞生长的影响.结果显示:H.pluvialis CG-11生长的适宜氮源形式是NaNO₃和NH₄NO₃;适宜H.pluvialis CG-11生长的氮浓度为41.2mg·L^-1,磷浓度为5.3～53.3mg·L^-1.

Abstract：

Cell growth rate, chlorophyll a content, carotenoid content, dry weight, and astaxanthin content were measured to study the effects of nitrogen and phosphorus nutrients on the growth of green vegetative cells of Haemalococcus pluvialis CG-11 that was cultivated in BBM medium. The experiments were carried out separately as three single factor tests. It was found that both NaNO₃ and NH₄NO₃ were suitable nitrogen sources for the cell growth. Suitable N concentration for the algae growth was 41.2 mg·L^-1. Suitable P concentration for the algae growth was 5.33~53.3mg·L^-1.

Key words： Haematococcus pluvialis green vegetative cell nitrogen phosphorus
