Abstract
Cells of obligate methylotrophic Gram-negative bacterium Methylobacillus flagellatum KT which can only grow on methanol and methylamine media possess three different carriers mediating uptake of methylamin depending on growth conditions. All three uptake systems are energy-dependent, the methylamine uptake was inhibited by oxidative phosphorylation uncoupler and respiratory inhibitors. The first active transport system for methanol in the cells of obligate methylotroph was also demonstrated. The parameters of this system were measured, their dependence on energy, presence of respiratory inhibitors and uncoupler was shown.
