  • Title: Effect of insulin on microbial growth.
    Author: Plotkin BJ, Viselli SM.
    Journal: Curr Microbiol; 2000 Jul; 41(1):60-4. PubMed ID: 10919401.
    Abstract:
    The ability of insulin to affect the growth kinetics of Escherichia coli, Staphylococcus aureus, Enterococcus faecalis, and Pseudomonas aeruginosa was measured. For all organisms, insulin, in the absence of a metabolizable sugar source, i.e., glucose or starch in Mueller-Hinton medium, had no effect on generation time as compared with a homologous control. Response to insulin, in the form of increased or decreased generation times, for both Gram-positive and Gram-negative bacteria, was dependent on the concentration of insulin, the concentration of glucose present, and the initial concentration of bacteria exposed to the glucose and insulin.
