Several moderately halophilic gram-positive, spore-forming bacteria have been isolated by conventional enrichment cultures from damaged medieval wall paintings and building materials. Enrichment and isolation were monitored by denaturing gradient gel electrophoresis and fluorescent in situ hybridization. 16S ribosomal DNA analysis showed that the bacteria are most closely related to Halobacillus litoralis. DNA-DNA reassociation experiments identified the isolates as a population of hitherto unknown Halobacillus species.
