Iron availability enhances the cellular energetics of aerobic Escherichia coli cultures while upregulating anaerobic respiratory chains.

Aerobic Escherichia coli growth at restricted iron concentrations (≤ 1.75 ± 0.04 μM) is characterized by lower biomass yield, higher acetate accumulation and higher activation of the siderophore iron-acquisition systems.

The Probiotical Potential of Lactobacilli from Therapeutic Preventive Beverage Kurunga.

Introduction: Kurunga is a dairy drink made of a mix of lactic acid and alcoholic fermentation, characterized by high biological value based on protein composition, amino acid spectrum, fatty acid composition of lipids, vitamin and mineral substances, and physiological activity of microbiota containing lactobacilli, lactococci, bifidobacteria, and yeast. Among the probiotic correctors of normal microbiota isolated from national products, lactobacilli was of particular interest, with regards to a therapeutic - preventive effect. The aim of the study was to examine the probiotic properties of lactobacilli from kurunga.
