False LB constituent expansion is withdrawn. Source-specific amounts and preparation boundaries supersede flattened concentrations. Existing chemical annotations and earlier history are preserved, not recertified; no organism-growth association is added. Source preparation context (main preparation): Add and mix all components except for OADC. Bring to a boil to dissolve agar and autoclave at 121ºC. Cool to 50-55ºC and aseptically OADC.
