👉 Nanohalococcus is a Gram-negative, rod-shaped bacteria that has been discovered in the marine environment. It belongs to the family of Gram-positive bacilli and is commonly found in the deep sea and the open ocean. Its cells are characterized by their small size (nanometer), which makes it difficult to visualize directly. The cell wall of this bacterium consists primarily of a cellulose layer, but it also contains other components such as chitin and lignin.
