Analysis of growth and dextran production of Lc. lactis AV1n and its recombinant derivative strains. (A) wild-type strain, (B) Lc. lactis AV1n[pRCR21], and (C) Lc. lactis AV1n[pRCR15] grown in MRSG, MRSS, MRSM, or MRSF at 20, 30, and 37°C. Levels of dextran produced by the LAB at A600 nm = 1.0 are also depicted. The mean values and the standard deviation of three independent experiments are depicted.
