BRIX PRODUCTION FROM CASSAVA PEELS AND OPTIMIZATION OF BIOETHANOL SYNTHESIS USING SACCHAROMYCES CEREVISIAE

The purpose of this paper is to produce and optimize brix from cassava peels for bioethanol production using Saccharomyces cerevisiae. The use of agricultural waste products in bioethanol production helps in decreasing reliance on food crops. Optimization of production medium is required to maximise...

The capacity of Saccharomyces cerevisiae to ferment wort derived from cassava peels, an agricultural waste, in optimized conditions to produce bioethanol, was investigated.

The use of agricultural waste products in bioethanol production helps in decreasing reliance on food crops. Optimization of production medium is required to maximise metabolite yield.
