Protective effect of betaine on survival of Lactobacillus plantarum subjected to drying

The aim of this study was to investigate the effect of betaine on survival of Lactobacillus plantarum subjected to drying. A defined medium was devised devoid of betaine. Addition of 2 mM betaine to this medium increased the growth rate of cells grown under osmotic stress and also made the organism...

More Information
Summary:The aim of this study was to investigate the effect of betaine on survival of Lactobacillus plantarum subjected to drying. A defined medium was devised devoid of betaine. Addition of 2 mM betaine to this medium increased the growth rate of cells grown under osmotic stress and also made the organism more tolerant. Cells cultivated under osmotic stress of 0.6 M sodium chloride and in the presence of betaine showed an increased survival after air drying and subsequent vacuum desiccation to a water activity of 0.12.
