The present study is aimed at determining the performance of an amylolytic Lactobacillus plantarum MSUL 702 for lactic
acid production from the repeated-batch and simultaneous saccharification and fermentation (SSF) of a synthetic cassava
starch wastewater (SCW). An ability of the bacteria to treat the SCW in terms of chemical oxygen demand (COD) and
total kjeldahl nitrogen (TKN) removal efficiencies was also investigated during the fermentation processes. The SSF
experiments were performed for five consecutive batches under a non-sterile condition and at a room temperature. The
highest lactic acid concentration and viable lactic acid bacteria at 28.71 g/L and 9.26 log CFU/mL, respectively, were
obtained in the 48 h of the first batch fermentation. The highest COD and TKN removal efficiencies at 98% and 85%,
respectively, were obtained in the 48 h of the second batch fermentation.
