  • Stabilization of immobilized bacteria
    Patent number: 4246349
    Abstract: Bacteria immobilized by adsorption on an inorganic carrier are stabilized by carrying out the adsorption procedure in the presence of from about 1 to about 20% weight per volume of sucrose of nonfat dry milk solids and lyophilizing the adsorbed bacteria.
    Type: Grant
    Filed: September 5, 1978
    Date of Patent: January 20, 1981
    Assignee: Corning Glass Works

  • Means for stimulating microbial growth
    Patent number: 4166006
    Abstract: This invention is concerned with the use of fluorocarbon and silicone oil greases or gels to stimulate the growth of various microorganisms. More particularly, the instant invention contemplates the addition of a peroxide compound, preferably hydrogen peroxide (H.sub.2 O.sub.2), to fluorocarbon and silicone oil greases or gels to further stimulate the growth of anaerobes and facultative anaerobes in liquid or solid nutrient media.
    Type: Grant
    Filed: November 10, 1977
    Date of Patent: August 28, 1979
    Assignee: Corning Glass Works
    Inventors: William Hertl, William S. Ramsey
  • Method for distinguishing gram positive and gram negative microbes
    Patent number: 4126516
    Abstract: Microbial culture device containing a growth medium having incorporated therein a lipophilic fluorescent material and means associated therewith for localizing and identifying the growth of colonies of an unknown microbe, and a known gram positive microbe, and/or a known gram negative microbe. The device can be used to determine whether an unknown microbe sample is gram positive or gram negative by culturing the unknown on the medium and then comparing the fluorescence of the unknown microbes with fluorescence of similarly cultured gram positive and/or gram negative microbes.
    Type: Grant
