Abstract
Aerobic organisms including the gut microbiota have an essential antioxidant status, as a result of which these bacteria protect organisms from various pathologies and diseases. The goal of the given investigation is (1) the isolation and purification of the isoforms of endogenous О2--producing associate from gastrointestinal bacteria (Lactobacillus rhamnosus, Lactobacillus acidophilus, Bifidobacterium bifidum); (2) determination of the effective concentrations of exogenous О2- produced by a complex of NADPH-containing protein component and Fe(III) (NPC-Fe(III)) from raspberries on the growth of the gastrointestinal bacteria in a nutrient medium in vitro. Ion-exchange chromatography on cellulose DE-52 and gel filtration on Sephadex G-100 at the pH of 9.5 was used to isolate and purify the NLP-Nox isoforms. Specific maximal optical absorption spectra of the Nox isoforms were observed in a weakly opalescent aqueous solution of the NLP-Nox isoforms. The specific contents of these NLP-Nox isoforms, as well as their composition, the stationary concentration of produced О2-, and the mechanism of О2- production were determined. The stimulating effect on the growth of these gastrointestinal bacteria in the nutrient medium of MRS broth and MRS agar in vitro under the influence of О2-, as a product of a new thermostable and acid-stable complex NPC-Fe(III) was determined. The NPC-Fe(III) complex, from raspberries was determined as well. Thus, for the first time, the isolation and purification of О2-- producing thermostable NADPH-containing lipoprotein-NADPH oxidase (NLP-Nox) associate from gastrointestinal bacteria membranes (continuously producing О2- under the aerobic conditions), and the stimulation of these bacteria growth by О2- formed by the complex from raspberries were demonstrated.
