Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Background:

Traditional endophyte screening for phytoremediation is time-consuming and inefficient.
Identifying optimal strains and their application efficiency remains challenging.
Endophyte-assisted phytoremediation offers a sustainable solution for heavy metal-contaminated soil.

Purpose of the Study:

To develop a novel, high-throughput microfluidic method for screening endophytes.
To identify effective endophytes for enhancing phytoremediation of hyperaccumulators.
To validate the efficiency of the microfluidic screening approach.

Main Methods:

Utilized microfluidic technology for real-time plant root phenotyping.
Simultaneously incubated multiple endophyte-plant systems.
Evaluated root growth rate and heavy metal (HM) concentration in effluent.

Main Results:

Screened Bacillus paramycoides (PE1) as a highly effective endophyte within two weeks.
PE1 increased root growth rate by 54.31% and reduced Cd concentration by 46.33%.
Pot experiments confirmed PE1 increased P. acinosa biomass by 42.50% and Cd removal by 55.49%.

Conclusions:

The microfluidic method provides an efficient and rapid approach for endophyte screening.
PE1 demonstrates significant potential for improving phytoremediation of Cd-contaminated soil.
This technology advances understanding and application of endophyte-assisted phytoremediation.
