Tradescantia pallida extract inhibits biofilm formation in Pseudomonas aeruginosa. [PDF]

Nagoya journal of medical science, 2019
Pseudomonas aeruginosa is capable of biofilm formation. In this study, we investigated the effects of aqueous Tradescantia pallida extract on Pseudomonas aeruginosa growth and biofilm formation. Aqueous Tradescantia pallida extracts significantly inhibited both bacterial growth and biofilm formation.
