The effect of inoculation of white mustard seeds (Sinapis alba L.) by cells of endophytic Bacillus subtilis (strains 26D and 11VM) on the growth and the formation of malondialdehyde (MDA) in plant tissues under the cadmium ions action (Cd-stress) has been stadied. It has been shown that plants inoculated with B. subtilis cells, under Cd-stress differed higher rates of biomass and less intense accumulation of lipid peroxidation products than untreated bacteria plants. Reduced the content of malondialdehyde in plant tissues, inoculating by bacterial cells, may be indicative of a less intense development of the oxidative stress caused by the ions Cd. The growth-stimulating and anti-stress effects of Bacillus subtilis were more noticeable in plants grown in soil in pot experiments, than during the growth of plants in a petri dish in an aqueous solution.
