The combination of chemical and physical stressors that bacteria face during wastewater treatment can impact the transfer of genes between them. But while certain combinations of stressors significantly increase the gene-transfer rate, other combinations reduce it, KAUST researchers have discovered. The finding could inform best practice design and management of wastewater treatment for reuse.
Globally, many regions are considering treated wastewater as a potentially invaluable freshwater source. “As part of the Saudi Vision 2030, water reuse and treatment rates need to be increased,” says Bothayna Al-Gashgari, a Ph.D. student in Peiying Hong’s group, who led the research. “Facilitating safe treatment and reuse is crucial,” she says.
