| Abstract: |
| In order to expand the source of biodiesel feedstock, the characteristics of aerial microalgae Heveochlorella sp. Yu as raw material for biodiesel were studied by measuring its growth curve, biomass, lipid productivity, sedimentation rate, etc. The results showed that the microalgae biomass after cultivation was 4.14 g/L, the lipid content was 39.43%, and the lipid productivity was 181.38 mg/(L·d). The natural sedimentation rate of aerial microalgae Heveochlorella sp. Yu within 2 h was 65.28% (which could greatly concentrate the water body and reduce the harvesting cost of microalgae). In addition, aerial microalgae Heveochlorella sp. Yu could produce gamma-aminobutyric acid (GABA) with a content of 9.50 mg/g. The aerial microalgae Heveochlorella sp. Yu had the potential to be used as a feedstock for biodiesel and had the development value of microalgae lipid. |
