Benzo[a]pyrene forms during high temperature food processing, enters the body via ingestion, raising food safety concerns. Research on degrading food's toxic substances with food-derived microorganisms is crucial for food safety, environment, and human health. In the present study, Bacillus haynesii TM-41 and Kluyveromyces marxianus TD-3 were isolated from benzo[a]pyrene degrading Kefir and co-culture system was constructed by pure culture and co-culture degradation experiments. Under the conditions of initial benzo[a]pyrene concentration of 19 mg/l, temperature of 35 °C, pH value of 6.0 and degradation time of 78 h, the final degradation rate of benzo[a]pyrene by co-culture system reached 71.08%. Metabolomics results showed that the TD-3 in the co-culture system degraded and utilized benzo[a]pyrene to provide energy for its partner TM-41. Conversely, TM-41 synthesizes and secretes specific amino acids, which are assimilated by TD-3 to fulfill its nutritional demands for growth. This study elucidated the synergistic mechanism of co-cultured microorganisms for the degradation of benzo[a]pyrene and highlights the potential of food microbial strain resources for the removal of benzo[a]pyrene. |
