experiment
• Root biomass
increased after
WSM1325 (BRo)
inoculation compared to control
• Plant growth
higher with both
bacterial strains
inoculation
• Co-inoculation
of isolates,
decreases metal
toxicity, in plant
growth
• More Zn
bioaccumulation,
translocation
showed significantly
• BRPZn set
reduces Zn from
soil
