Statistical Optimization of Animal Feed Production from Lactic Acid Fermentation Residue of Kitchen Waste

摘要：

In this paper, yeast fermentation for animal feed production from lactic acid fermentation residue of kitchen waste was studied. Positive significant factors (urea and unsterilization non-sterilization) and negative significant factors (K<,2>HPO<,4> and MgSO<,4>) were screened from nine factors by Plackett-Burman design. The optimum conditions of yeast fermentation were found by using Central Composite design. Maximum real protein production of 30.34％ was obtained with urea 2.67％, inoculation 12.5％, temperature 31℃, increasing 7.11％ comparing with the protein content of lactic acid fermentation residue (23.23％).
