The present disclosure discloses a method for improving production of L-lactic acid (L-LA) by Saccharomyces cerevisiae based on regulation and control of ethanol metabolic flux, and belongs to the technical field of microorganisms. According to the present disclosure, acid-resistant Saccharomyces cerevisiae TJG16 is used as a production strain, an ethanol dehydrogenase gene adhA derived from Bacillus subtilis is introduced to promote conversion of ethanol into acetaldehyde, and a lactate aldolase gene BAL derived from Brucella sp. is introduced to promote synthesis of lactic acid from the acetaldehyde. Moreover, an acetaldehyde dehydrogenase gene ALD6 is knocked out to prevent synthesis of acetic acid from the acetaldehyde, a transcriptional regulatory factor encoding gene GAL80 for regulating and controlling galactose is knocked out, and lactate dehydrogenase LDH is integrated, so that the L-LA is finally increased.

Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.
