How do bacteria store their carbohydrate?

Bacteria store their carbohydrates in the form of glycogen or polyhydroxybutyrate (PHB) granules within their cells. Glycogen is a branched polymer of glucose units, similar to how animals store energy in the form of glycogen in their liver and muscles. PHB is a type of biopolymer that bacteria can synthesize and accumulate as a reserve energy source when nutrients are abundant. These carbohydrate stores can be broken down and used as an energy source when needed by the bacteria.
