Abstract: The genus Bacillus contains Gram-positive, aerobic or facultatively anaerobic bacteria that are able to produce bacterial endospores. Spores have a very strong resistance to heat, ultraviolet light, dry, ionizing radiation and a lot of toxic chemicals. As spore properties, Bacillus research has becoming more and more important. International journal of systematic and evolutionary microbiology (IJSEM), published by the Society for General Microbiology (SGM), is the leading forum for the publication of new taxa of bacteria and yeasts. The papers were mainly introduced references of Bacillus in IJSEM in the past ten years, and approached several desirable questions.
