Keywords: Chlorella sp., glucose, acetic acid, glycerol, response surface methodology.
It indicated that the suitability of second-order polynomials could predict the response function. The maximum dry cell weight (0.547 g/L) of glucose, acetic acid and glycerol concentrations were 0.5 g/L, 0.5 g/L and 1.875 g/L with low organic carbon concentration, and 60.0 g/L, 1.0 g/L and 1.0 g/L with high organic carbon concentration, respectively.
The results indicated that biomass production of Chlorella sp. depends on the concentration of organic carbon source and chemical composition of organic matters. High concentrations of organic carbon substrate might lead to the inhibition. The mutual effect of organic carbon condition is also not benefit to the biomass accumulation of Chlorella sp., comparing with single organic carbon substrate.(Download PDF) (Export to EndNotes)
