Characterization and Identification of Some Aerobic SporeForming Bacteria Isolated From Saline Habitat, West Coastal Region, Saudi Arabia
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2017, Vol 12, Issue 2
Abstract
Ten isolates of aerobic endospore- forming moderately halophilic bacteria were isolated fromsaline habitat at the west coastal region near Jeddah. All isolates that were Gram positive, catalase positive andshowing different colony morphology and shapes were studied. They were mesophilic, neutralophilic, with temperature range 20-40°C and pH range 7-9. The isolates were separating into two distinct groups facultative anaerobic strictly aerobic. One isolate was identified as Paenibacillus dendritiformis, two isolates as Bacillus oleronius, two isolates as P. alvei, three isolates belong to B. subtilis and B. atrophaeus, and finally two isolates was identified as Bacillus sp. Furthermore, two aerobic endospore-forming cocci, isolated from salt-march soil in Germany were tested for their taxonomical status and used as reference isolates and these isolates belong to the species Halobacillus halophilus. Chemotaxonomic characteristics represented by cell wall analysis and fatty acid profiles of some selected isolates were studied to determine the differences between species.
