Abstract


Experiment was designed for ethanol production using corn and
other organic waste material containing starch contents and
cellulosic material while barely used for diastase and acidic
digestion methods. The effect of temperature, yeast, barely diastase
and various dilutions of acid (sulfuric acids) were investigated on
ethanol production. The result showed that corn yielded high
amount of ethanol (445ml) as compared to cellulosic material which
produced 132ml of ethanol from one kg of weight. It was also noted
that with the increase of barely and yeast amount in a proper manner
can increase ethanol production from different starch sources. It was
also noted that acid dilutions affected cellulose digestion where high
yield of reducing sugar was noted at 0.75% of sulfuric acid dilution.
It was concluded from the present experiment that economical
sources of starch and various dilutions of acids should be tried on
cellulose digestion for bio-fuel production to withstand in this
energy crisis time.
