Growth Condition
Strains Corynebacterium glutamicum lysCfbr
Genotype lysCfbr
Culture medium Complex medium containing 5g/L glucose,5g/L yeast extract,10g/L tryptone,5g/L NaCl and 18 g/L agar was used for agar plates.First pre-cultures were grown in the same medium without agar.Second pre-cultivation and main cultivation was performed in minimal medium with 80mM glucose as carbon source. The minimal medium additionally contained per liter:0.055g CaCl2-2H2O,0.2g MgSO4-7H2O,1.0g NaCl,16.0g K2HPO4,2.0g KH2PO4,5.0g (NH4)2SO4,0.5mg biotin,1mg Ca-panthothenic acid,1mg thiamine-HCl,20mg FeSO4,30mg 3,4-dihydroxybenzoic acid and 10ml of trace element solution.
Carbon source Glucose.
