Abstract

The growth and lipid productivity of original Chlorella pyrenoidosa and its ion implantation mutant strains were studied. The results showed that the lipid productivity of the mutant strain was 32.5mg/(L·d), 23.81% higher than that of the original strain. According to the fatty acid methyl ester analysis by gas chromatography, ion implantation did not change the composition of fatty acid, but enhanced the content of monounsaturated fatty acids, which was conducive to the enhancement of biodiesel quality. After cultivation, the effluent quality was also found to reach the emission standard of first level A, and the mutant showed better degradation ability than the original strain. Phylogenetic tree showed that the mutant and the original strains were belonged to interspecific variation.
