Ph of butanol
Webbetween pH 5.0 The optimal pH for butanol fermentation using different carbohydrates is usually between pH 5.0 and pH 6.5 (Jones and Woods, 1986). Accordingly, we found that … WebIn a recent report, microbial cultures, such as Escherichia coli have been developed for producing butanol with concentrations in the range of 14–16 g/L. The newly developed butanol-producing strain cannot tolerate butanol in excess of 15 g/L as butanol is more toxic than isobutanol [138].
