Abstract: | The compositions and contents of astaxanthin esters and fatty acids in four types of Haematococcus pluvialis cells were studied by HPLC and GC-MS. Results showed that the synthesis and accumulation of astaxanthin was independent of
the formation of cysts, but was highly correlated with the synthesis and accumulation of fatty acids, though it is an well
known phenomenon that the accumulation of astaxanthin is usually accompanied by the formation of cyst. The red cysts contain
more than 30% of fatty acids, with 81% of the unsaturated fatty acids. Taken together, besides a resource of astaxanthin,
H. pluvialis would be a good resource of valuable fatty acids.
