Abstract
Aerobic, endospore-forming bacteria were found in soil taken from an active fumarole on Lucifer Hill, Candlemas Island, South Sandwich archipelago. Amplified rDNA restriction analysis, SDS-PAGE, repetitive element primed-PCR (rep-PCR) and routine phenotypic tests suggested that six of the isolates represent a novel taxon, and 16S rDNA sequence comparisons support the proposal of a novel species, Bacillus luciferensis sp. nov., the type strain of which is strain LMG 18422(T) (=CIP 107105(T)).
