2.2.1. Feed material
The gathered peels were chopped into small pieces approximately
2e4 cm in length using a knife. The pieces were then sun
dried under mild sunlight for two days and then dried at 60 C in an
oven for one day. Next, the samples were taken out of the drier once
they were dry enough to be crushed. The cut pieces were then
crushed in the grinder. The ground sample was divided proportionally
into seventeen separate samples of 10 g of ground banana
peels and another two separate samples of 20 g of ground banana
peels. A juice was prepared for each sample by adding 10:1 (v/w)
ratio of distilled water to the sample in separate flasks [16]. The
lignocelluloses molecules must be broken down into free sugars
before the fermentation required for alcohol production [17].
