Effect of carbon source on vitamin K2 production in L. lactis ssp. cremoris MG1363. a Fold changes in specific concentrations with respect to the control group (glucose). b Fold changes in titres with respect to the control group (glucose). c Relative abundance of MKs. Strain MG1363 was cultivated in M17 supplemented with indicated carbon source, statically incubated at 30 °C for 48 h. Values shown are from averages ± SEMs of biological triplicates. For Dunnett test (2-sided) the control group was glucose (*P ≤ 0.05; **P ≤ 0.01; ***P ≤ 0.001)
