Fig. 2From: Bioconversion of sago processing wastewater into biodiesel: Optimization of lipid production by an oleaginous yeast, Candida tropicalis ASY2 and its transesterification process using response surface methodologyEffect of different airflow rates on the production of biomass yield, lipid yield, and lipid content of C. tropicalis ASY2 in ALB. The experiment was conducted in a 5 L airlift bioreactor with a working volume of 3.5 L at different airflow rates of 1 to 9 L min–1. Values are mean (± standard error) (n = 3)Back to article page
