From the results, it could be concluded that soybean molasses is
an attractive raw material for the production of bio-ethanol. Since
it provided the necessary nitrogen and magnesium and the appropriate
hydrogen balance for the fermentation, there was no need
for supplementing these additionally or making any pH adjustment.
The laboratory process was scaled-up with promising results.
The residue of bio-ethanol production, called soybean
vinasse, did not present any environmental problem since it was
employed as raw material for energy co-generation
