👉 Aliibacillus is a bacteria genus in the family Bacteroidetes that belongs to the order Bacillariophyta and is characterized by its large, flat-shaped cells with two distinct cell walls. These cells contain an outer membrane around them, which protects them from external pathogens. Aliibacillus is found in many marine environments, such as the Great Barrier Reef, where it plays a vital role in nutrient cycling through the corals.
