CC-217 spr-u-sp-23 (nit+) mt+ Locus: 16S rRNA, chloroplast genome
Source: From Ruth Sager, April 1974
Comment: Like most of Sager's strains, CC-215 grows on nitrate as sole N source (indicated by the NIT allele designation). This property is in contrast to most strains from the Ebersold/Levine background, which carry the nit1 and nit2 mutations.
