  • Patent number: 5173319
    Abstract: A method for inhibiting the growth of bacteria in raw or processed meat products having a pH between about 6.0 and 6.5 stored at above freezing temperatures using an inorganic propionate salt which extends the shelf life of the meat is described. The salt is preferably sodium propionate or calcium propionate and is used in an amount less than about 1% by weight and preferably between about 0.05 and 0.5 percent by weight of the meat such that no flavor is imparted to the meat.

  • Patent number: 5066588
    Abstract: A lactose-fermenting (Lac.sup.+), mucoid (Muc.sup.+) Streptococcus lactis transconjugant designated ML-3/2.230 was obtained by conjugative co-transfer of Lac.sup.+ Muc.sup.+ phenotypes from Lac.sup.+ Muc.sup.+ Streptococcus cremoris MS to lactose-negative (Lac.sup.+), non-mucoid S. lactis ML-3/2.2. Curing studies on the transconjugant ML-3/2.230 showed that Muc.sup.+ phenotype in the strain was encoded on two plasmids, pSRQ2203 and pSRQ2204. DNA hydridization experiments also indicated the involvement of two plasmids in the expression of the mucoid phenotype. Plasmid pSRQ2203 also contained genetic information for lactose utilization (Lac.sup.+).

  • Patent number: 4918014
    Abstract: A method for imparting phage resistance to phage sensitive strands of Streptococcus group N is described. The method involves transferring plasmid encoding for production of a mucoid substance (Muc.sup.+) into the phage sensitive strain. Even if the Muc.sup.+ plasmid is removed by curing at elevated temperatures the strains remain resistant to phage. The resulting resistant strains are novel and are used for fermentations, particularly milk fermentations.

  • Patent number: 4912047
    Abstract: An improved method for inhibiting psychrotrophic bacteria in raw milk is described. The method uses a non-lactose fermenting strain of a lactobacillus to generate hydrogen peroxide which inhibits the psychrotrophic bacteria. A preferred strain is Lactobacillus casei subspecies alactosus NRRL-B-12344 which is a superior producer of hydrogen peroxide at 5.degree. to 8.degree. C.

  • Patent number: 4910143
    Abstract: A mixture of Pseudomonas putida one having plasmids encoding the camphor (CAM) and toluene (TOL) degradation and the other having a plasmid encoding for naphthalene (NAH) degradation is described. The mixture is more effective than either Pseudomonas putida alone or than a single Pseudomonas putida with three related plasmids which encode for the degradation of CAM, TOL and NAH.
