👉 Parvularchaeota is the classification of bacteria that includes Gram-positive, Gram-negative, and some non-membrane-borne bacteria. These bacteria are characterized by their ability to form a cell wall, which helps them form a protective structure called a stroma, and they can survive in various environments including soil, seawater, and even in extreme temperatures. They primarily belong to the order Bacillae and are also part of the family Erysipelothrix.
