Fehlstämme
Fehlstämme are a biological concept referring to strains of organisms that have lost specific functions or characteristics. This loss typically occurs due to mutations in their genetic material. These mutations can be spontaneous or induced by environmental factors. The resulting Fehlstämme may exhibit altered growth patterns, metabolic capabilities, or responses to stimuli. For example, a bacterium might become a Fehlstamm if it loses the ability to synthesize a particular amino acid, requiring it to be supplied in its growth medium.
The study of Fehlstämme is crucial in various fields of biology, including genetics, microbiology, and molecular
