SINGLE CELL PROTEIN (SCP) PRODUCED FROM BIOCONVERSION OF PINEAPPLE PEELSUSING Saccharomyces cerevisiae ISOLATED FROM BURKUTU

Abstract

 Most Agro-allied wastes scattered in the environment as pollutants, can be bioconverted to single cell protein.Single-Cell Protein (SCP) represents microbial cells (primary) grown in mass culture and harvested for use as protein sources in foods or animal feeds. The production of single cell protein (SCP) from pineapple peels using Saccharomyces cerevisiae isolated from burkutu was investigated. The yeast was isolated using pour plate technique on saboraud dextrose agar (SDA) medium and was identified using standard techniques. The single cell protein (SCP) produced wereSCP sample A (control), sample B (glucose + mineral + nitrogen source), sample C (mineral + nitrogen sources) in submerged fermentation (SF). Physicochemical,pre and post proximate analysis/ composition of the pineapple peel and SCP and microbial analysis of the single cell protein (SCP) were carried out. The yeast isolated was identified as Saccharomyces cerevisiae. Sample B gave the highest yield of 5.42% followed by sample C whichhad 4.60% while sample A (control) had the least yield of 4.50%.The physicochemical parameters showed varying values from the beginning of the fermentation to the end.The result of the proximate composition of pineapple peel before fermentation revealed moisture content of 4.80%, ash content of 4.72%, protein content of 4.30% , fat content of 4.07%, crude fibre content of 16.92% and carbohydrate content of 65.19%. The results of SCP samples showed that there were variations in the proximate compositions with sample B as the best. The SCPcan serve as alternative to other protein souces.
