title: Patulin biodegradation by marine yeast Kodameae ohmeri.
abstract: Patulin contamination of fruit- and vegetable-based products had become a major challenge for the food industry. Biological methods of patulin control can play an important role due to their safety and high efficiency. In this study, a strain of marine yeast with high patulin degradation ability was screened. The yeast was identified as Kodameae ohmeri by the BioLog identification system and partial 26S rRNA gene sequencing. The degradation products of patulin were identified as (E)- and (Z)-ascladiol through HPLC and LC-TOF/MS. High patulin tolerance at 100 μg ml(-1) and a high degradation rate at 35°C at a pH between 3 and 6 indicates the potential application of K. ohmeri for patulin detoxification of apple-derived products.
