Synergistic effect of hypocrellin B and curcumin on photodynamic inactivation of Staphylococcus aureus

Microbial Biotechnology, 2021
Summary Antimicrobial photodynamic inactivation (aPDI) serves as a new approach to control the growth of foodborne bacteria. It remains elusive if the photodynamic efficacy of hypocrellin B (HB) can be potentiated by joint action with curcumin.

Sonophotodynamic Inactivation: The power of light and ultrasound in the battle against microorganisms

Journal of Photochemistry and Photobiology, 2021
The inactivation of pathogenic microorganisms that are a threat to the human being is an old challenge that needs to be overcome, mainly because microorganisms are able to develop resistance that leads to the failure of the treatment.

Genotoxic effect of photodynamic therapy mediated by curcumin on Candida albicans [PDF]

, 2015
Photodynamic therapy (PDT) is a promising method for localized and speci c inactivation of fungi and bacteria. A nontoxic light-sensitive compound is taken up by cells, which are then exposed selectively to light, which activates toxicity of the compound.

Photodynamic Decontamination of Food: Assessing Surface Challenges Against Listeria monocytogenes

Microorganisms
Listeria monocytogenes is a foodborne pathogen of significant concern. While it typically causes mild, self-limiting gastroenteritis, it poses a much higher threat to immunocompromised individuals and pregnant women, where it may lead to miscarriage ...
