Bacillus fastidiosus
''Bacillus fastidiosus'' is an aerobic, motile, rod-shaped bacterium that has been isolated from soil and poultry litter. The species was first isolated and described by the scientist Den Dooren de Jong in 1929. This organism is a mesophile that contains ellipsoidal spores that do not cause swelling of the sporangia. ''Bacillus fastidiosus'' is only able to grow in the presence of uric acid, allantoin, or allantoic acid.
==Morphology==
''Bacillus fastidiosus'' has peritrichous flagella meaning that it has flagella in a uniform distribution all over the cell that it uses for motility.〔 Cells of this species are about 5 µm long and 1.5 µm wide. They may contain endospores that can be located centrally, paracentrally, or subterminally. This bacterium is typically grown on 1% uric acid agar and colonies can have a rhizoid appearance. Colonies are typically opaque and may become yellowish over time. The cells will produce ammonia as a byproduct of their metabolism, which means that their microenvironment will become highly alkaline. This creates a self-limiting cycle that creates zones of inhibition around each colony. ''B. fastidiosus'' is catalase and oxidase positive. It is unable to produce acid or gas when grown in the presence of carbohydrates such as glucose. ''B. fastidiosus'' is able to hydrolyze urea, but it is unable to hydrolyze casein, gelatin, or starch.
