The fine structure of Micrococcus radiophilus and Micrococcus radioproteolyticus

Arch Microbiol. 1976 Apr 1;107(3):313-20. doi: 10.1007/BF00425346.

Abstract

The radiation resistant bacteria Micrococcus radiophilus and M. radioproteolyticus were studied by thin sectioning and freez-etching techniques and the two species were found to be similar in the fine structure. The only significant difference was in the appearance of the surfaces of the cell walls in freeze-etched preparations. Since the two species, together with M. radiodurans, possess a unique cell wall structure and a cell wall peptidoglycan, which is different from that of other micrococci and Gram-positive cocci, it is recommended that they be reclassified into a new genus.
