In the processing of poultry for the production of prepared foods such
as soups and frozen dinners, wastewater is generated containing signi
ficant quantities of fats, protein and starchy materials. These materi
als must be removed from the wastewater before it is discharged. Typic
al recovery consists of removing the solids through a combination of d
issolved air flotation and filtration. The solids can then be rendered
and utilized as poultry feed. This paper investigates an alternative
to traditional processing in biologically producing valuable single ce
ll protein from poultry processing waste. The results of fermentation
experiments to produce single cell protein by both direct and indirect
routes are presented.
