Gottschalkiaceae Poehlein et al. 2017
General information
Description and emendation
Strictly anaerobic bacteria that can only grow by metabolizing purines. Gram-stain-positive, straight or slightly curved rods, 0.5-1.5 × 2-10 µm. Produces lateral and subterminal flagella. Growth occurs from 18-19°C to 37-42°C, the optimum growth temperature is 30-37°C. The pH range is from 6.5 to 7.0 to 9.0, with the optimum pH between 7.5 and 8.2. May be spore-forming or asporogenous. In the presence of 0.1% (w/v) yeast extract, can grow using uric acid, guanine, or xanthine as the sole carbon and energy sources; some representatives may also utilize other purines. Do not utilize carbohydrates and most amino acids; in the presence of purines, may use glycine, serine, or glycine-containing peptides. Major products of metabolism are acetate, formate, CO2 and NH3. Oxidase-, catalase-, lipase- and urease-negative. Nitrate and sulfate are not reduced. Cell walls contain meso-diaminopimelate. Predominant fatty acids are C14:0 and C16:1. Often associated with avian droppings and can be isolated from soil, and aquatic marine and freshwater sources. The family includes the genera Gottschalkia and Andreesenia. The G+C content of the chromosomal DNA ranges from 28 to 44 mol%.
