Bioethanol Production from Fruit Biomass as Bio-antiseptic (antibacterial) and Bio-antifermenter: Its Physical, Chemical and Biochemical Properties as an Innovation

摘要

The study was carried out to investigate the optimization of bioethanol production and evaluate the bioethanol as antifermenter and antiseptic using banana, grape and dates biomasses through fermentation bioprocess using yeast. Bioethanol yield was higher in dates biomass than in grape and banana biomass at 3g/l yeast concentration at 30°C and lower at 1 and 5 g/l yeast concentration at 28°C and 32°C. Moreover, the lowest pH was found in the bioethanol produced from dates biomass. The lower TSS was found in the bioethanol produced from banana biomass. In addition, the glucose content was lowest in the bioethanol produced from the banana biomass and highest in the bioethanol produced from the date biomass. The lowest viscosity and acid value was found at 3mg/l of yeast concentration in dates biomass. Chemical elements like Ca, P, Fe, Pb, Cu, and Si fulfilled the requirement of the standard specification as well. Grape juice mixing with bioethanol showed antifermenter for 2 days while in the first day juice started to rot the faster in the control. The lowest bacterial colony formation was observed in the dates biomass derived bioethanol. Results explored that produced bioethanol was of good quality and can be used as antiseptic and bio-solvent from fruit biomass.
