PROTEOBACTERIA

In this course you have to learn about Proteobacteria which are included in eubacteria kingdom. Include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera. proteobacteria Include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera.

Most Proteobacteria are mesophilic, but some thermophilic. A great number of Proteobacteria are motile by means of polar or peritrichous flagella, whereas the myxobacteria. ØMost of the known Proteobacteria are free-living; some (such as the rhizobia) enter in symbiotic associations with specific leguminous plants, where they fix nitrogen in root or stem nodules.

types of organisms such as Purple Phototrophic Bacteria, Nitrifying Bacteria, Sulphur and Iron Oxidising Bacteria, Hydrogen Oxidising Bacteria, Methanotrophs, Acetic Acid Bacteria, Bioluminescent and Related Bacteria.

Gram negative non proteobacteria consist Phylum Aquificae, Thermotogae, Deinococcus-Thermus Chlorobi, Chloroflexi, Cyanobacteria, Planctomycetes, Chlamydiae, Spirochaetes, Bacteroidetes. Planctomycetes form a distinct phylum of the domain bacteria and possess unusual features such as intracellular compartmentalization and a lack of peptidoglycan in their cell wall. Bacteroides ruminicola is a major component of the rumen flora; it ferments starch, pectin, and other carbohydrates.

thus, The proteobacteria represents a largest group of microorganisms and phenotypically nearly a diverse phylogenetic lineage. These groups of microbes are commercially applied for various fields such as medical, industrial, veterinary, and agriculture. Soil and plants harbor a diverse group of biodiversity.
