Other claims from this paper (15)
- Observation The maximum tolerable Pb concentration for the Bacillus megaterium isolate was 450 ppm.
- Observation The isolate was confirmed as Bacillus megaterium with greater than 98% sequence similarity.
- Observation The bacterium grew uninhibited at 50 ppm Pb(NO3)2.
- Observation The bacterium showed partial growth suppression at Pb(NO3)2 concentrations of 100-250 ppm.
- Observation The bacterium showed pronounced growth inhibition at 350-450 ppm Pb(NO3)2.
- Observation The isolated strain exhibited multiple plant growth-promoting traits.
- Intervention effect In uncontaminated soil, inoculated tomato plants had 6-24% greater shoot and root length and dry biomass than controls.
- Intervention effect Under Pb-contaminated soil, inoculation significantly enhanced tomato shoot length by 23%.
- Intervention effect Under Pb-contaminated soil, inoculation significantly enhanced tomato root length by 26%.
- Intervention effect Under Pb-contaminated soil, inoculation significantly enhanced tomato shoot and root dry weight by 37%.
- Intervention effect Inoculation increased tomato N uptake by 4.5% in uncontaminated soil.
- Intervention effect Inoculation increased tomato P uptake by 25.3% in uncontaminated soil.
- Intervention effect Inoculation increased tomato K uptake by 13.8% in uncontaminated soil.
- Intervention effect Inoculation increased tomato P uptake by 3.6% under Pb stress.
- Intervention effect Inoculation increased tomato K uptake by 26.7% under Pb stress.
