Study on Yeast Extract Production from the Waste Water of MGS

The waste water of MGS, including orgnic compounds, sugar and many kinds of inorganic salts etc, can be used for producing a kind of natural flavour—yeast extract. After inoculation and aerated culture, yeast mycelium can be obtained. Autolysis and some other enzyme engineering technique were used to form the final product, which includes amino acid,peptide, polypeptide, nucleotides, vitamins, microelement and other nutrition components. Because of its strong odour increasing effect and richly meaty flavor, it has a wide applications in food industry.
