Figure 2. Carbohydrate analysis of unidirectional interactions. TLC plates of secondary degraders: (A) L. symbiosum WAL 14673 from B. bifidum JCM 1254 supernatants; (B) L. symbiosum WAL 14673; (C) B. longum M12; and (D) B. thetaiotaomicron VPI-5482 (secondary degrader) from B. thetaiotaomicron VPI-5482 supernatants. SN: Supernatant obtained from the primary degrader after 24 h of culture; t0: time 0 (secondary degrader inoculation); t48: 48 h of secondary degrader culture.
