Abstract This study investigated the metabolic activity and survival of five lactic acid bacteria strains in citrus flavanone standards. The results showed that L. plantarum N13 and L. brevis LB01 could metabolize hesperetin-7-O-rutinoside, while L. plantarum N13, L. acidophilus LA85, and L. brevis LB01 could metabolize naringenin-7-O-rutinoside. L. acidophilus LA85 exhibited the highest...
