“…These conditions have been investigated in more detail for other fuel ethanol-related strains, such as the ones involved in corn-based ethanol industry (ZHAO; BAI, 2009). For baker's strain, temperature, pH, sugar concentration, nitrogen (ALVES, 1994, GUTIERREZ, 1989, potassium, sulfite (ALVES, 1994), nitrite (GUTIERREZ; ORELLI, 1991), 2,4-dinitrophenol (GUTIERREZ, 1989(GUTIERREZ, , 1991, benzoic acid (GUTIERREZ et al, 1991a), acetic acid (GUTIERREZ et al, 1991b), and octanoic acid (GUTIERREZ, 1993) had their effects investigated. Noteworthy, sulfite up to 300 mg L -1 slightly increased glycerol formation but did not affect ethanol yield, yeast viability, or cellular trehalose levels, possibly because it reduced bacterial growth and, consequently, lactic and acetic acid concentrations in the culture medium (ALVES, 1994).…”
