Lipids of microalgae. I. Lipids and a protein hydrolysate fromMonochrysis lutheri

The class composition and the total fatty acid composition of the readily- and difficulty-extractable lipids and the amino acid composition of a protein hydrolysate of the dry biomass from the golden-yellow microalgaMonochrysis lutheri have been determined for the first time. It has been established that the difficulty-extractable lipids differ sharply from the readily extractable lipids in the composition of the neutral and glycolipid components and also in that of the fatty acids; 27% of the weight of the fatty acids of the latter is composed of the 20:4 and 20:5 species. The protein hydrolysate ofM. lutheri contains almost the whole set of essential fatty acids.
