From: Heme and menaquinone induced electron transport in lactic acid bacteria
Lactococcus lactis MG1363 and Lactobacillus plantarum WCFS1 were grown aerobically overnight at 30°C in M17-medium and MRS-broth respectively. A large biomass increase (grey bars), without further acidification (white bars), is observed when Lactococcus lactis is grown with heme, while Lactobacillus plantarum requires menaquinone (K2) in addition to heme. The error bars represent the standard deviation.
