Deinococcota (synonym, Deinococcus-Thermus) is a phylum of bacteria with a single class, Deinococci, that are highly resistant to environmental hazards, also known as extremophiles.[4] These bacteria have thick cell walls that give them gram-positive stains, but they include a second membrane and so are closer in structure to those of gram-negative bacteria.[5][6][7]
