Polyamine stress at high pH in Escherichia coli K-12

BMC Microbiology, 2005
Background Polyamines such as spermine and spermidine are required for growth of Escherichia coli; they interact with nucleic acids, and they bind to ribosomes. Polyamines block porins and decrease membrane permeability, activities that may protect cells

Main effects of ascorbic acid levels and organic acid type on physicochemical properties, microbial populations, texture, and biogenic amine formation in sucuk

Journal of the Science of Food and Agriculture, Volume 106, Issue 8, Page 4942-4950, June 2026.
Abstract BACKGROUND Sucuk is a traditional Turkish dry fermented sausage, the quality and safety of which depend on physicochemical, microbiological, and biochemical changes during fermentation and ripening. Organic acids, their salts, and antioxidants such as ascorbic acid (AA) are widely used in fermented meat products; however, information about ...
