US EditionChemicals from turmeric and rhubarb could help fight antibiotic-resistant bacteria lurking in wastewater
LOGAN, UTAH, JUL 10 – Natural compounds curcumin and emodin inhibited growth of multiple antibiotic-resistant bacterial strains found in wastewater, offering a potential alternative to traditional antibiotics, researchers said.
- A team of researchers from Utah State University, led by senior author Liyuan Joanna Hou, published a study on July 10, 2025, in Frontiers in Microbiology examining antibiotic-resistant bacteria present in wastewater.
- The study arose from discovering multidrug-resistant bacteria, including strains resistant to colistin, in effluent sampled from a Logan, Utah wastewater treatment plant.
- The team tested 11 natural compounds derived from plants, selecting curcumin from turmeric and emodin from rhubarb for their antimicrobial and anti-biofilm properties against Gram-positive resistant bacteria.
- They found that curcumin combined with higher doses of emodin reduced bacterial cell activity and biofilm formation, while noting some Gram-negative bacteria resisted all tested compounds.
- The findings suggest these natural compounds could help control antibiotic resistance in wastewater, but further research and pilot trials are needed to assess feasibility and long-term effects.

Chemicals from turmeric and rhubarb could help fight antibiotic-resistant bacteria lurking in wastewater
When people take antibiotics, some of the dose is excreted with urine and feces and ends up in our wastewater. The presence of this low dose of antibiotic creates an opportunity for resistant bacteria to evolve.
