The utilization of fungi for protein production has been studied for years. The efficiency of fungi has been shown in substrates like lignin, cellulose and hemicellulose -polymers found in fruit wastes [1-6]. Stamford et al. have used passion-fruit waste for microbial protein production [7], as Senez et al. have used potato and banana wastes [8].
Considering that substantial amounts of waste products are available free or sold at very low prices by local agroindustries, the upgrading of wastes from fermented fruits for use in balanced feeds for poultry is potentially advantageous.
The purpose of this study was to investigate the conversion efficiency of pineapple-waste carbohydrates into single-cell protein (SCP).
