Patents by Inventor Nadine C. Collins

Nadine C. Collins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5571716
    Abstract: Gram-negative bacteria, which are obligate alkaliphiles, have been isolated from samples of soil, water and sediment and a number of other sources obtained from in and around soda lakes. These bacteria have been analyzed according to the principles of numerical taxonomy with respect to each other, as well as to a variety of known bacteria. In addition, these bacteria are further circumscribed by an analysis of various chemotaxonomic characteristics. The bacteria produce various alkali-tolerant enzymes which may be used in various industrial processes requiring such enzymatic activity in a high pH environment.
    Type: Grant
    Filed: April 8, 1993
    Date of Patent: November 5, 1996
    Assignee: Gist-brocades, N.V.
    Inventors: Brian E. Jones, William D. Grant, Nadine C. Collins

  • Patent number: 5401657
    Abstract: The present invention provides novel aerobic, Gram-positive alkaliphilic bacteria which have been isolated from in and around alkaline soda lakes. These alkaliphiles have been analyzed according to the principles of numerical taxonomy with respect to each other and also to a collection of known bacteria. In addition, these bacterial taxa are further circumscribed by an analysis of the lipid components which serve as chemotaxonomic markers. The alkaliphiles of the present invention produce alkalitolerant enzymes which are capable of performing their functions at high pH which makes them uniquely suited for applications requiring such extreme conditions.
