A bradytroph is a strain of an organism that exhibits slow growth in the absence of an external source of a particular metabolite. This is usually due to a defect in an enzyme required in the metabolic pathway producing this chemical. Such defects are the result of mutations in the genes encoding these enzymes. As the organism can still produce small amounts of the chemical, the mutation is not lethal. In these bradytroph strains, rapid growth occurs when the chemical is present in the cell's growth media and the missing metabolite can be transported into the cell from the external environment. A bradytroph may also be referred to as a "leaky auxotroph".

Examples of bradytrophic strains of microorganisms include mutants defective in thiamine production in Bacillus subtilis, as well as strains of Saccharomyces cerevisiae with mutations that impair arginine biosynthesis.

If the function is entirely lost, the mutation is called a null mutation. If is also possible that some function may remain, but not at the level of the wild type allele. These are called leaky mutations. Loss of function mutations are typically recessive.
