From the calculation it was found that the addition of benzathine
penicillin G enhanced the fermentation process by 8.97%. In
open literature this type of work was not found. One of the authors
(Barber et al., [27]) has investigated the ethanol production potential
of local yeast strains isolated from ripe banana peels, and
they found that Saccharomyces kluvveri K-6 would ferment 40% (v/
v) of the glucose at 30 C to yield 3.6e5.8% ethanol. Hence, the
experimental result was found to be impressive. The material balance
for the production of bioethanol was performed both before
and after the experiment and is shown in Table 8.
