Quizplus · Accepted Answer

Auxotrophic bacterial strains require nutritional supplements to grow in a minimal medium. These strains have lost the ability to synthesize an essential nutrient or metabolic intermediate and therefore rely on external sources of the nutrient for survival. Autotrophic, prototrophic, phototrophic, and heterotrophic bacterial strains do not necessarily require nutritional supplements to grow in a minimal medium.
