Abstract:
Lactobacillus plantarum ATCC e8014 and L. plantarum (MC) were sensitive to NO2- under anaerobic conditions. This sensitivity was linked to an increase in cell-associated manganese levels. Normal manganese levels under aerobic conditions in the presence of NO2- were 1 × 107 atoms/cell. Under anaerobic conditions with NO2-, these levels increased to 3 × 108 to 2 × 109 atoms/cell depending on the sensitivity of lactobacilli to NO2-. This study suggests that in trace metal metabolism, NO2- may stimulate uptake or transport of ions such as manganese.

Sodium Regulation
Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...
