Regulation of an Outer Membrane Protein, OmpW, Expression and Its Biological Function in - Outer membrane proteins (OMPs) expressed in the Gram negative bacteria such as Salmonella play multiple func-tions including material transports, adhesive factors and reception of external signals. This study has been focused on an OmpW protein known as a protein required to form a hydrophobic porin in outer membrane. We have constructed a S. typhimurium CK10 mutant deleting an ompW gene on chromosome. The CK10 strain was more tolerant to SDS than the wild-type strain did. As increase of salt concentration in the culture media, significantly decreased amount of OmpW protein in cells were detected. The maximum OmpW protein was expressed in the absence of salt supplement. However, the growth of CK10 strain was indistinguishable compared to that of the wild-type strain at the variable osmotic conditions. The biological role of differential OmpW expression in response to osmotic conditions remains to be investigated.

Lactic acid bacteria comprise an ecologically diverse group of microorganisms united by formation of lactic acid as the primary metabolite of sugar metabolism (Davis et al., 1985b; 1988; Lonvaud-Funel, 1999; Carr et al., 2002; Liu, 2002). These bacteria utilize sugars by either homoor heterofermentative pathways (Section 2.4.1) as well as l-malic acid, a major acid present in grape must (Section 2.4.3). Whereas growth of some bacteria in certain wines is desirable (i.e., malolactic fermentation or MLF), growth of other species can lead to spoilage.

Prevention Thoroughly cook foods, particularly meat, poultry, and gravies, to a safe internal temperature. Use a food thermometer to make sure. Keep food hot after cooking (at 140? F or above) and serve meat dishes hot, within 2 hours after cooking. Microwave leftovers thoroughly (to 165?F or above). Refrigerate leftovers within two hours of preparation (at 40?F or below). Divide large amounts of food, such as roasts or big pots of chili or stew, into shallow containers and refrigerate immediately. It is OK to put hot foods directly in the refrigerator.
