Time-course profile of lactic acid yield, lactic acid productivity, and the growth (OD₆₀₀) of Lactobacillus plantarum 23 during lactic acid fermentation using microalgal biomass as feedstock. The feedstock from WT (A) and M4 mutant (B) strains was obtained from 8-day culture under aeration with 6% CO₂. The content of glucose in wild type (WT) and M4 mutant in the fermentative mixture was adjusted to around 21 g/L, while the xylose content was around 2 g/L
