title: Outbursting wedges of the colonies of Clostridium welchii containing chain forming mutants after ultra violet irradiation.
abstract: Cl. welchii NCTC 6785 was irradiated with UV light. The 40 minutes irradiated cells after 3-8 days ageing at room temperature (22-25 degrees C) and 48 hours initial incubation at 37 degrees C produced hairy outbursting wedges. These wedges gave rise to the colonies composed of chain forming mutants, which on transfer into the fluid medium grew into a pure chain forming culture.
