Non-fermenters (also non-fermenting bacteria) are a taxonomically heterogeneous group of bacteria of the division Proteobacteria that cannot catabolize glucose, and are thus unable to ferment. This does not necessarily exclude that species can catabolize other sugars or have anaerobiosis like fermenting bacteria.
The coccoid or bacillary bacteria can be found in soil or wet areas. They are non-sporulating bacteria and Gram-negative. Some species are also pathogenic for humans, so their detection (e.g. with API 20 NE) has great relevance in the diagnosis of bacterial infections.
