Description
M9 Minimal Salts are a commonly used base for preparing a defined synthetic medium for the growth of most E. coli host cells. The powder is reconstituted in sterile purified water, (or water with melted purified agar added.) Additional nutrients, such as glucose or other carbon source, casamino acids, vitamins, or antibiotics are added when the solution cools and before plates are poured or media is inoculated with bacteria.
