Mechanisms of the marine yeast <i>Debaryomyces hansenii</i> for protection against reactive oxygen species produced during benzo(a)pyrene biotransformation.

ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs), such as benzo(a)pyrene (BaP), are persistent environmental pollutants recognized for their high toxicity and resistance to microbial degradation. The marine yeast Debaryomyces hansenii has emerged as a compelling candidate due to its ability to thrive under a variety of stressful conditions. This study presents a molecular and biochemical analysis of the responses of D. hansenii to BaP exposure, providing insights into the detoxification and antioxidant mechanisms. In this study, we explored BaP removal from the medium and characterized the associated molecular and biochemical responses induced by this compound. Our findings demonstrate that D. hansenii can grow in BaP concentrations up to 100 ppm without compromising cell viabi
