Cultivation of E. coli and related enterics: General-purpose growth medium for routine culture, maintenance, and overnight starters.

Bacteriophage propagation: Supports growth conditions for phage infection and amplification (e.g., lambda, T4, T7, M13) in E. coli hosts.

Plaque assays: Used as the broth base for preparing soft (top) agar overlays and host lawns for phage titration.

Plasmid maintenance and cloning workflows: Suitable for starter cultures used in cloning, screening, and routine plasmid propagation in E. coli.

Antibiotic selection: Employed with selectable markers (e.g., ampicillin, kanamycin) for screening recombinant E. coli.

Thiamine-dependent strains: Provides thiamine supplementation (Thiamine HCl) beneficial for strains requiring vitamin B1 (e.g., certain E. coli F′ strains).

Culturing other nonfastidious bacteria: Applicable to organisms like Bacillus subtilis for routine growth where a simple tryptone/NaCl medium is appropriate.
