Table 2.
Chl a, Chl b, BCar, and culture pH of D. salina grown under different levels of glycerol, non-isosmotic salinity, and light intensity. The initial pH range was 6.20–6.35, and the final pH corresponds to the 7th day of cultivation. Values in the same columns with different superscript are significantly different.
