“…SRB do not metabolize complex organic compounds, such as those included as substrates in the test medium, instead metabolize short chain organic acids (low-molecular-weight organic acids). Fermentative bacteria produce a variety of low molecular weight organic compounds, and these include organic acids (acetic, L-ascorbic, gluconic, glucuronic, formic, peroxides and oxalic, oxalacetic, butyric, succinic, propionic, fumaric, citric, malic, and glyoxylic acid, kojic, phenylacetic, indolylacetic, dihydroxydibenzenecarboxylic, glutaconic and 4-hydroxymandelic acids), ketones, and alcohols (ethanol, propanol, and butanol) (Bao et al, 2012;Kushkevych et al, 2021;Lugauskas et al, 2009;Naranjo et al, 2015;Sand and Gehrke, 2003;Tran et al, 2021).…”
