The minimum inhibitory concentration(MIC) of an antibiotic is defined as the lowest concentration of the compound that completely inhibits the initiation of growth of a particular bacterium under standardized in vitro conditions. It has been reported that antibiotics at sub-MICs have numerous effects on bacteria, including morphological changes, modifications of cell wall structure, altered growth kinetics, inhibition of enzyme or toxin production, and loss of adhesive properties...

Subject field(s)
  • Biological Sciences
CONT

A number of the ecological factors thought to influence the development of the micro-flora of vacuum-packaged beef were examined(0(subscript) 2 CO2 within the vacuum-package was found to be less important than 0(subscript) 2 concentration in producing a lactic flora. The inhibitory effects of lactic organisms in mixed culture were also studies. Finally, a representative selection of lactic organisms from vacuum-packaged beef was surveyed for their ability to cause proteolysis, lipolysis, dextran production and H(subscript) 2O(subscript) 2 production. Results suggested that a significant proportion were potential spoilers.
