The high content of the essential fatty acids in some microalgae and baker's yeast has made them excellent diets for boosting the fatty acid content of livefood Artemia. The influences of baker's yeast (Saccharomyces cerevisiae) and three microalgae, viz., Chlorella salina, Chaetoceros calcitrans, and Nannochloropsis salina, were tested as diet components in marine livefeed brine shrimp Artemia salina
一些微藻类和面包酵母中必需脂肪酸的含量很高,使它们成为提高活食卤虫中脂肪酸含量的绝佳饮食。测试了面包酵母(Saccharomyces cerevisiae)和三种微藻的影响,即盐藻小球藻,Chaetoceros calcitrans和Nannochloropsis盐藻作为海洋活饲料盐水虾卤虫无节幼体的饮食成分,以改善多不饱和脂肪酸(PUFA)的组成。发现在这些饮食中淹没的无节幼体在四个不同的富集间隔(3、6、8和24小时)中都掺入了必需脂肪酸,并在富营养的无节幼体和富集的饮食中测量了不同脂肪酸的百分比组成。盐沼猪笼草产生的花生四烯酸(AA,20:4n6,9.50%),二十碳五烯酸(EPA,20:5n3,25.80%)和二十二碳六烯酸(DHA,22:6n3,4.18%)。盐沼猪笼草富集的卤虫的总PUFA含量在长达8 h的富集期内增加了56.50%,随后的24 h显着减少。在富集8小时后,盐沼
