True about Bacterial capsule is following except: (A) Prevents Phagocytosis, (B) Stains by gram stain, (C) Protects bacteria from lytic enzymes, (D) Lost by repeated subcultures
Answer is B. Gram staining differentiates bacteria by the chemical and physical propeies of their cell walls by detecting peptidoglycan, which is present in a thick layer in gram-positive bacteria. So gram stain is not a stain of capsule it is a stain of cell wall.
