minimal medium

minimal medium

A term of art for a culture medium which provides the minimum requirements (e.g., inorganic salts, but no amino acids) needed for growth of a particular bacterium or cell.

minimal medium

a food source containing the minimum set of nutrients required for growth of the wild-type of a particular species. These are carbon, inorganic salts and water. Such media are used in screening for AUXOTROPHS. See ONE GENE/ONE ENZYME HYPOTHESIS.

Complete feather degradation by these isolates was determined by using 20ml minimal medium (0.03% K2HPO4, 0.04% KH2PO4, 0.05% NaCl, 0.01% MgCl2) with 0.5% (w/v) native feathers as the sole source of carbon.
coli strains were grown at 37[degrees]C with aeration at an agitation rate of 180 rpm in LB medium (for overnight growth) or M9 minimal medium (containing 6.4 g/L [Na.sub.2]HP[O.sub.4]*7[H.sub.2]O, 1.5g/L K[H.sub.2]P[O.sub.4], 0.25 g/L NaCl, and 0.5 g/L N[H.sub.4]Cl) supplemented with 2 mM MgS[O.sub.4], 0.1 mM Ca[Cl.sub.2], 0.1 mM casamino acids, and 1% glycerol as the sole carbon source (for growth during the analysis).
