👉 Flavobacteriaceae is a family of Gram-negative, rod-shaped bacteria that belongs to the order Eubacteria and class Firmicutes. These bacteria are characterized by their unique cell wall composition, which includes a complex lipid bilayer containing lipopolysaccharides (LPS) and lipopolysaccharide-like proteins called chitinases. They are found in soil, water, and various aquatic environments as primary producers that play important roles in nutrient cycling and decomposition processes
