Abstract

1419060 Protein supplement for animal feed UNIVERSITY OF QUEENSLAND 6 June 1974 [6 June 1973 22 April 1974] 25144/74 Heading A2B [Also in Division C6] Yeast protein supplement for animal feeds is produced by subjecting raw or sterilized aqueous biological waste material such as yellow straw e.g. wheat straw, food waste, pig waste and pig or human faeces to anaerobic fermentation, introducing yeast into the fermented material, the yeast being a pellicleforming yeast capable of growing as a surface layer, allowing a surface layer of the yeast to grow on the aqueous material, skimming off the surface layer, and drying and milling the skimmed yeast to form a proteinaceous powder. The dry product contains 40-50% protein and when incorporated in pig feed in an amount of 8% by weight provides all the riboflavin, niacin, pantothenic acid and Vitamin B 12 needed. Yeasts: Candida ingens and Pichia membranaefaciens. It is stated that the anaerobic fermentation probably produces a series of volatile mono-carboxylic fatty acids which in the presence of nitrogen, act as feed for yeast growth. The longer-chain fatty acids are taken up by the yeast in preference to the shorter-chain ones. The fermentation may be carried out in a conventional overloaded septic tank, the fermented material being transferred to an open-topped container, or in an elongated flow-through vessel.
