    Abstract

    One hundred and nineteen thermotolerant and thermophilic Bacillus strains isolated from solar-heated and non-heated environments in Jordan were classified by numerical techniques. Some strains were classified into thermophilic taxa which did not equate with established species. However, most of the isolates were identified phenotypically as Bacillus licheniformis, a conclusion supported by the high DNA hybridization which was detected between these strains and a reference strain of this species (> 64% at optimal renaturation temperature). Several of the B. licheniformis isolates had a higher ratio of iso-C15 and iso-C17 fatty acids to the anteiso equivalents in their membranes than the reference strain of B. licheniformis and they grew more strongly at high temperature than the reference strain. This suggests that the B. licheniformis isolates represent thermotolerant variants of this species.
