Figure 3: Effects of different media and carbon sources on the production of crude laparaxin by L. paracasei NRRL B-50314. Specifically, carbon sources of MK 2% mannose (1), MK 2% lactose (2), MK 2% fructose (3), MK 2% glucose (4), MRSsi 2% glucose (5), MRSsi 1% sucrose (6), and MRSsi 1% cellobiose (7) were shown. Components of MK and MRSsi are described in Materials & Methods. The antibacterial assays were performed in 96 well plates against L. Lactis LM 2030 with the amounts of each substrate indicated as % (g/100 ml). The substrate percentages depicted are an average of three experiments.
