Abstract

BIOSIS COPYRIGHT: BIOL ABS. Two marine Yeasts, Candida parapsilosis and Debaryomyces hansenii were found to be capable of growth in presence of the organophosphorus pesticide, Ekalux EC 25. They utilized the pesticide as a source of phosphorus, suggesting their role in degradation of organophosphorus pesticides. They were found resistant to the heavy metals tested (mercury, copper, cadmium, zinc and lead). The minimal inhibitory concentration (NEC) for these metals showed great variation. These isolates could produce both acid and alkaline phosphatases in the presence of the pesticide, Ekalux. This study shows the potential of marine yeasts for biodegradation of organic compounds entering in the aquatic system.
