[Effects of different trophic modes on growth characteristics, metabolism and cellular components of Chlorella vulgaris].

Objective: We studied the effects of trophic modes related to glucose and light (photoautotrophy, mixotrophy and heterotrophy) on growth, cellular components and carbon metabolic pathway of Chlorella vulgaris.

Methods: The parameters about growth of algal cells were investigated by using spectroscopy and chromatography techniques.

Results: When trophic mode changed from photoautotrophy to mixotrophy and to heterotrophy successively, the concentrations of soluble sugar, lipid and saturated C16/C18 fatty acids in C.
