Feathery outbrusts of the colonies of Clostridium sporogenes containing chain forming mutants after ultraviolet irradiation.
Cl. sporogenes NCTC 532 was irradiated with UV light, 20 mins. irradiated colonies after initial 48 hours incubation at 37 degrees C and 10-20 days ageing at room temperature (22 to 25 degrees C), gave rise to feathery outbrusts. The material from these outbursts grew in long chains in fluid media. A pure chain - forming culture could not be obtained as the single cells or pairs always "contaminated" the chain - forming culture.
