The Deinococci are a class of bacteria , the only one in the division ( Phylum ) Deinococcus-Thermus . The bacteria have thick cell walls. Therefore, they appear Gram-positive after a Gram stain . However, they also have a second cell membrane, as is typical for Gram-negative bacteria.
The class consists of the two orders Thermales and Deinococcales . So far, comparatively few species could be assigned to it, some of which, however, have remarkable properties. Thus, Deinococcus radiodurans and Deinococcus radiophilus for their resistance to ionizing radiation known Thermus aquaticus lives in geysers and hot springs.
Systematics
The following families and genera are assigned to this class:
- Order I. Deinococcales Rainey et al. 1997
