摘要：

The lipid composition of the green alga Botryococcus was studied at three different cultivation temperatures: suboptimal (18degreesC), optimal (25degreesC), and supraoptimal (32degreesC). Cultivation at the supraoptimal temperature was found to considerably inhibit the synthesis of nearly all intracellular lipids, except for triacylglycerides, and to influence their fatty acid composition. In particular, the content of trienoic fatty acids was significantly lower at the supraoptimal than at the optimal cultivation temperature. At the same time, the fatty acid composition of the extracellular lipids of the alga virtually did not depend on cultivation temperature.
