  • Production of lactate using crabtree negative organisms in varying culture conditions
    Patent number: 6485947
    Abstract: Crabtree negative organisms such as Kluyveromyces, Pichia, Hansenula and Candida, are used to make selected organic products such as lactic acid. The organisms are cultured in a first culture medium that includes glucose, under conditions that promote cellular respiration. The organisms are then cultured under a second set of conditions that promote production of the selected organic product. The organisms preferably contain an exogenous lactate dehydrogenase gene.
