Summary

The morphological, cultural, nutritional and general physiological properties of two species of bacteria, isolated from soil, are described which require for growth vitamin B12 and the terregens factor respectively. Both organisms undergo the change in morphology from a rod stage in young culture to a coccoid stage in older culture which is characteristic of members of the genus Arthrobacter Conn and Dimmick and are considered to be most appropriately assigned to this genus. In view of their differences from other described species and from each other the organism for which vitamin B12 is essential is named Arthrobacter duodecadis n. sp. and that requiring the terregens factor Arthrobacter flavescens n. sp.
