Phenotypes of bacterial mutants

PHENOTYPES OF BACTERIAL MUTANTS
  • Antibiotic or drug resistance
  • Nutritionally deficient or auxotrophic mutants
  • Changes in colonial form or ability to produce pigments
  • Antigenc mutants
  • Resistance to bacteriophages
  • Changes in ability to produce spore, capsule or flagella
  • Loss of function but retaining the intracellular enzymatic activities to catalyse the reactions. Eg: loss of permease ( cryptic mutants)
  • Conditionally expressed mutants
  • Altered fermentation ability
