Modern agriculture relies heavily on agrochemicals that can adversely affect
non-target organisms, including microorganisms. In terms of agricultural sustainability,
herbicideresilient plant growth-promoting (PGP) bacteria that can
improve crop yield are critical. Previously, we isolated 122 high herbicide concentration
tolerant (HHCT) bacteria from soils contaminated with S-metolachlor,
a widely used herbicide. Initially, in vitro experiments were conducted to screen
potential candidates for further evaluation. Our goal was to identify HHCT bacteria
with high PGP potential, and the ability to improve soil quality and biocontrol
activity. Subsequently, the most promising candidates were grouped
into three consortia and evaluated in pot for their effects on corn seed germination,
early-stage plant development, and root colonization. Experiments were
conducted with seeds of commercial maize hybrids under controlled conditions,
with and without the presence of the herbicide S-...metolachlor. The results
showed that the consortia positively affected seed germination and promoted
higher germination rates. The bacterial isolates showed the ability to colonize
the root system of maize, with significant effects of the consortia on shoot and
root biomass and shoot and root length. However, it was observed in some
consortia that the presence of herbicides resulted in plant damage. Markedly,
the presence of the herbicide S-metolachlor reduced or reversed the beneficial
effects of bacterial consortia. This could be due to incomplete biotransformation
of the herbicide leading to the formation of toxic intermediates. The selection
of bacterial consortia that not only promote plant growth but also have the ability
to fully biotransform herbicides is critical. In conclusion, the isolated HHCT
bacteria showed promising PGP potential and formed an effective consortium
to promote maize seed germination and early-stage development. However,
careful consideration of the selection of bacterial consortia is required to ensure
their compatibility with herbicides and to minimize negative impacts on plant
health and environmental sustainability.
