研究了胁迫对不同培养条件下雨生红球藻虾青素产量的影响。高浓度的 NaCl（> 1.0% w/v）是致命的，培养物的年龄对于应激诱导的虾青素产生至关重要。 4 到 8 天的培养物对 NaCl 添加敏感，而较老的培养物（12-16 天）则具有抗性。较老的细胞积累了 8.3-10.69 mg/l 的虾青素，而 4-8 天培养的细胞则积累了 0.95-8.1 mg/l。与其他氮源相比，以硝酸钙作为氮源生长的培养物在胁迫下表现出虾青素含量和产量显着增加。同样，在 pH 7.0 下生长的培养物比在 pH 6.0、8.0 和 9.0 下生长的培养物显示出更多的虾青素产量。 (C) 2002 年，爱思唯尔科学有限公司出版。
The influence of stress was studied on astaxanthin production in Haematococcus pluvialis grown under different culture conditions. High concentrations of NaCl ( > 1.0% w/v) were lethal and the age of the culture was crucial for stress induced astaxanthin production. Four to-eight-day-old cultures were sensitive to NaCl addition while older cultures (12-16 days) were resistant. Older cells accumulated 8.3-10.69 mg/l astaxanthin compared to 0.95-8.1 mg/l in 4-8-day-old cultures, respectively. Cultures grown with calcium nitrate as nitrogen source showed a significant increase in astaxanthin content and production under stress compared to other nitrogen sources. Similarly, cultures grown at pH 7.0 showed more astaxanthin production than those grown at pHs of 6.0, 8.0 and 9.0. (C) 2002 Published by Elsevier Science Ltd.
