  1. The biomass (g dry weight/L PBR), glucose and xylose contents (%, g/g biomass) of Chlorella sp. GD wild type (WT) and M4 mutant after acid hydrolysis using 4% (v/v) H2SO4, as well as the lactic acid production performance of Lactobacillus plantarum 23. The biomass was obtained after 8 days of incubation in 1-L outdoor PBR under 6% CO2 condition. Data are presented as mean ± SD (n = 3)
  2. * Following the SD indicates significant difference at P < 0.05 using student t test
