| Description |
Addition of calcium carbonate enhanced ethanol
production by Z[momonas mobilis ZM4 and a mutant (ZMI2),
especially at higher concentrations (200-400 g/L) of glucose
and sucrose, as well as at higher temperature (42~C) by the
mutant. Calcium and sodium carbonates neutralized the acid
produced in the medium and enhanced the ethanol production. The
Na salts were less effective ~ the parent strain and were not
favourable for the mutant. Ca ions played a direct role in
augmenting ethanol production as evidenced by the efffect of
calcium chloride at controlled pH (5.5).
