Studies from State University Maringa in the Area of Staphylococcus aureus Reported (Reduction Of Staphylococcus Aureus In Vitro and In Milk By Photodynamic Inactivation Using Riboflavin and Curcumin As...).

A recent study conducted by researchers at State University Maringa in Brazil explores the use of photodynamic therapy (PDT) as a method for decontaminating food. The study focuses on the effectiveness of PDT in reducing the presence of Staphylococcus aureus (S. aureus), a foodborne bacterial pathogen. The researchers found that PDT, which involves the use of a photosensitizer compound, light, and molecular oxygen, was successful in inhibiting S. aureus in vitro and in fluid milk. However, the efficiency of the technique was impaired in milk due to its physiological environment. The study concludes that PDT can be a valuable complement to traditional food preservation technologies. [Extracted from the article]
