    Irradiation of Meat for the Production of Fermented Sausage (1985)

    Notes: Fermented sausage was prepared from batter which had been processed with gamma radiation to reduce the microflora. Doses up to, 500 Krad reduced the total aerobic bacteria in commercial batter up to 2.2 log cycles. Irradiation reduced the coliform and staphylococci counts to levels that minimized public health concern after fermentation. These reductions allowed the use of a lower inoculum and a longer fermentation. The reductions shifted the percent inoculum relative to the total population from 1% in the controls to 70% in the 500 Krad samples, and the shift in population resulted in a more uniform fermentation and final product.

    Enumeration of Radiation-Resistant, Nonsporeforming Bacteria (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0

    Notes: A new method was developed to enumerate radiation-resistant, nonsporeforming bacteria. Micrococcus spp. and two isolates of the Moraxella-Acinetobacter group were used as representatives of radiation-resistant bacteria. Soil samples were used to provide spores of a mixed flora. Samples were prepared in reconstituted nonfat dry milk solids, litmus milk and meat serum to evaluate the method in a food system. Three doses of 300 Krad each, separated with 1 hr incubations between each dose, were found to produce a maximum reduction in spores with a minimum reduction in radiation-resistant bacteria.

    Effect of Radiolytic Products on Bacteria in a Food System (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 49 (1984), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Inhibitory effects of radiolytic products were studied using Escherichia coli, Pediococcus cerevisiae, and two radiation-resistant micro- organisms, an isolate of Moraxella-Acinetobacter and a Micrococcus sp. End products of an irradiation dose of 300 Krads completely inhibited resistant organisms on an experimental medium with a very low concentration of nutrients. Plate count agar, with higher nutrient concentration, required 600 Krads to produce the same inhibition. On the same medium, radiation-sensitive organisms could tolerate products generated by a 1000 Krad dose. However, no inhibition could be detected when either Escherichia coli or Morax-ella-Acinetobacter was incubated at 5°C on the surface of fresh meat irradiated to 1500 Krad. The effects of inhibitory products in culture media could be mitigated by the addition of catalase or sodium pyruvate.

    Attachment ofSalmonella typhimurium andListeria monocytogenes to glass as affected by surface film thickness, cell density, and bacterial motility (1991)
    Springer
    Journal of industrial microbiology and biotechnology 8 (1991), S. 281-283 
    Details
    ISSN: 1476-5535
    Keywords: Biofilm ; Contamination ; Biofouling
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary With equal cell densities, surface film thickness did not influence the numbers ofSalmonella typhimurium andListeria monocytogenes cells which attached to glass. MotileL. monocytogenes cells had a greater cell surface charge and generally attached in higher numbers than non-motile cells.
