  • a Measurements on L. lactis NZ3900 (control), L. lactis MG1363acmAΔ1, L. lactis MG1363 (dltD), and L. lactis MG1363 (dltD acmAΔ1) were performed on exponentially growing cells. L. lactis PH3960 (Δalr) and L. lactis GB3960 (Δalr acmAΔ1) were depleted for d-Ala for 5 h before measurements were performed. For measurement the standard deviations are given.
