Alcaligenes
Encyclopedia
Alcaligenes is a genus of Gram-negative
, aerobic
, rod-shaped bacteria. The species are motile with one or more peritrichous flagella.
Alcaligenes species have been used for the industrial production of non-standard amino acids; A. eutrophus also produces the biopolymer
polyhydroxybutyrate
(PHB).
Gram-negative
Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol. In a Gram stain test, a counterstain is added after the crystal violet, coloring all Gram-negative bacteria with a red or pink color...

Aerobic organism
An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment.Faculitative anaerobes grow and survive in an oxygenated environment and so do aerotolerant anaerobes.-Glucose:...

Biopolymer
Biopolymers are polymers produced by living organisms. Since they are polymers, Biopolymers contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers based on the differing monomeric units used and the structure of the biopolymer formed...
polyhydroxybutyrate
Polyhydroxybutyrate
Polyhydroxybutyrate is a polyhydroxyalkanoate , a polymer belonging to the polyesters class that was first isolated and characterized in 1925 by French microbiologist Maurice Lemoigne. PHB is produced by microorganisms apparently in response to conditions of physiological stress...
