title: [Correlation of the DNA nucleotide makeup with the physiological and cytological characteristics of spore-forming anaerobic bacteria].
abstract: The nucleotide composition of DNA from 12 studied species of anaerobic bacteria belongs to AT type, with G+C varying from 28.4 to 36.8 mole%. In the anaerobic group of Clostridium bifermentans, a correlation has been established between the nucleotide composition of DNA, the type of appendages on spores, and some physiologo-biochemical characteristics. The nucleotide composition of DNA in the spores of four anaerobic species is shifted toward GC type as compared to DNA in the vegetative cells. Data on the content of GC pairs in DNA of the spores may sometimes be of a higher taxonomic value than the corresponding evidence on DNA of the vegetative cells.
