Auxotroph

Vedclass · Answer

(A) An $Auxotroph$ is a mutant microorganism that has lost the ability to synthesize a specific nutrient required for its growth due to a mutation in a biosynthetic pathway. Consequently,it cannot grow on minimal media unless the specific compound it cannot synthesize is added to the medium. In contrast,a $Prototroph$ is a wild-type organism that can synthesize all its required nutrients from simple inorganic sources. Therefore,the correct term for such a mutant is an $Auxotroph$.
