Individual VFA composition of the SW at different concentrations
(from 5 to 60 g/l) were analyzed at 0 h and 120 h using HPLC
(Fig. 2). HPLC results showed that among two acids, acetic acid
showed maximum removal than propionic acid. Among all the carbon
concentrations, bacteria grown at 5, 10 and 15 g/l showed
complete removal (100%) of both acetic and propionic acids within
120 h. Bacteria grown at 20 g/l concentration showed 95 ± 3%
