Definition
'Aerobacter' is an older, now largely obsolete, genus name for a group of bacteria. These bacteria were known for their ability to produce gas during fermentation. Currently, many species formerly classified as *Aerobacter* have been reclassified into other genera, most notably *Klebsiella*. They are gram-negative and rod-shaped. They were once significant in studies of bacterial metabolism and industrial fermentation processes. The term 'aerobacter' might still pop up in older scientific literature. It's important to understand its historical context.
