|Abstract:||The effect of pH from 5 to 10 on the simultaneous saccharification and fermentation (SSF) and separate hydrolysis and fermentation (SHF) of CEPT sludge. Experiment results show that SSF of CEPT sludge can produce higher lactic acid concentration than that of SHF of CEPT sludge. High concentration of CEPT (20% Solid content) intent to degradation and to synthesis more lactic acid under pH 7, has been found be convertible to 59 g/L lactic acid in Day 4. Although without inoculation, CEPT can also produce high concentrations of lactic acid in a short period of time. After DNA extraction from the Day 0 sludge and Day 4 sludge and analysis of 16s DNA, it was found that the lactobacillales abundance of Day 4 sludge is higher than Day 0 Sludge.|
