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 methodology

Table 2 Effect of mineral nutrients on the lipid yield of C. tropicalis ASY2 in SWW

Mineral nutrients	Biomass yield, g L^–1	Lipid yield, g L^–1	Lipid content, %
With mineral nutrients	2.89 ± 0.02^a	1.39 ± 0.02^a	48.10 ± 0.38^a
Without mineral nutrients	2.42 ± 0.06^b	1.03 ± 0.02^b	42.56 ± 0.55^b

Values are mean (± standard error) (n = 3) and values followed by the same letter in each column are not significantly different from each other within the observation day as determined by DMRT (p ≤ 0.05)
