Strain % Glycine added % of maximum OD600
With D-Ala Without D-Ala
NZ3900 0 98 94
NZ3900 1 94 97
NZ3900 2 89 84

Strains were grown until an OD600 of 0.5 was reached, after which the cultures were split in two, centrifuged, washed once with an equal volume of fresh medium, and resuspended in fresh medium. d-Ala (2 mM) and/or glycine (1 or 2%) were added and growth was followed during 22 h.
