  • Method of improving the efficacy of lactic acid bacterial starter cultures and improved starter culture compositions
    Publication number: 20050053582
    Abstract: Methods of enhancing the growth rate and/or controlling the metabolic activity of lactic acid bacteria and of improving the shelf life and/or the quality of an edible product using lactic acid bacterial organisms which are defective in their pyruvate metabolism. There is also provided starter culture compositions comprising such defective lactic acid bacteria as helper organisms and lactic acid bacterial starter culture strains. Useful helper organisms are Lactococcus strains which are defective with respect to pyruvate formate lyase (Pfl) and/or lactate dehydrogenase (Ldh) activity. The helper organisms may overexpress a gene coding for a NAD+ regenerating enzyme such as NADH oxidase encoded by nox gene.
    Type: Application
