  • Food-grade vector suitable for transforming a food-grade host cell use of said vector for transforming food-grade host cells and use of said transformed cells in biotransformation processes
    Patent number: 5627072
    Abstract: A food-grade vector is provided which is suitable for transforming a food-grade host cell and is incapable of replicating autonomously in the host cell due to deletion of the replicase gene.
    Type: Grant
    Filed: January 3, 1995
    Date of Patent: May 6, 1997
    Assignee: Van Den Bergh Foods Co., Division of Conopco Inc.

  • Process for the preparation of .alpha.-acetolactic acid
    Patent number: 5420021
    Abstract: The invention relates to a process for the production of .alpha.-acetolactate and/or diacetyl, wherein a recombinant micro-organism containing an .alpha.-acetolactate synthase-encoding sequence is incubated in a medium containing an .alpha.-acetolactate precursor. The invention also provides a recombinant vector comprising a nucleotide sequence coding for an enzyme, which vector upon transfer into a host micro-organism enables expression of the nucleotide sequence in the host micro-organism, wherein the enzyme has .alpha.-acetolactate synthase activity.
    Type: Grant
