Bacillus pantothenticus (n.sp.)

SUMMARY: A new mesophilic species of the genus Bacillus was isolated from soil. Within the genus it most nearly resembles B. circulans but is clearly distinct in that it produces no motile colonies and no gas from glucose in the presence of an inorganic nitrogen source, hydrolyses casein, liquefies inspissated serum and gives a restricted egg-yolk reaction. It also differs from all other Bacillus spp. tested in that its growth is stimulated by 4% NaCl, and that pantothenic acid satisfies a nutritional requirement. The name Bacillus pantothenticus is proposed.
