摘要: Abstract The hydrolysates from lipid-extracted microalgal biomass residues (LMBRs) were used as a source of nutrients for the cultivation Chlorella vulgaris lipid production under various CO 2 supply conditions, including different concentrations and aeration rates. Both parameters had significant effect on production. A concentration 5% was found to be most suitable growth. Microalga grew best at rate 0.5 vvm. At this rate, productivity maximum 3.83 g L −1 157 mg L d , respectively, but decreased lower or higher present results showed that LMBRs utilization effective in conditions.
