Synergistic actions of nisin, sublethal ultrahigh pressure, and reduced temperature on bacteria and yeast

Article Abstract:

Research was conducted to examine the synergistic actions of nisin, sublethal ultrahigh pressure (UHP), and reduced temperature on bacteria and yeast. The objective was to provide evidence of the synergistic action of nisin during and after UHP against Lactobacillus plantarum and to investigate whether the synergistic effect can be enhanced during a reduced-temperature pressure treatment. Increases in fatty acid saturation or diphosphatidylglycerol content and the lysylphosphatidyl content of the cytoplasm membrane of L plantarum were associated with increased susceptibility to UHP and nisin, respectively.

Effect of specific growth rate on fermentative capacity of baker's yeast

Article Abstract:

The specific growth rate of the glucose-limited, aerobic chemostat cultures has a greatly affects the fermentative capacity of the industrial strain Saccharomyces cerevisiae DS28911. The fermentative capacity under anaerobic conditions is not correlated with the presence of glucose and the in situ rate of alcohol fermentation in the glucose-limited, aerobic chemostat cultures. The findings suggest that a combine overexpression of pyruvate decarboxylase and phosphofructokinase can enhance the fermentative capacity of baker's yeasts.
