We utilized the finished sequence of the 1942 isolate as a reference strain for templated assembly of the remaining BG draft sequences. Two additional ATCC isolates of B. atrophaeus (49337 and 6537) were distinguishable from var. globigii on the basis of very high SNP/indel counts, lower coverage ofand percentage of reads mapping to the 1942 reference, and unique genomic features which supported their proposed classification as var.atrophaeus [14] . The distinguishing genomic features of var.atrophaeus strains and the delineation of the B. atrophaeus clade from B. subtilis will be published elsewhere.
