A Classification of the Bacteria

This section undertakes to present a somewhat simplified classification of all the known bacteria to give the advanced high school student or amateur a good overview of the genera of known bacteria. on a semi-professional level. When completed, this should give the serious college student a good understanding of the bacteria with emphasis on the overall picture and most important species.

I hope to keep it simple enough for students, farmers, and others to benefit. It is intended for such people. The professionals have their own reference books. These pages can never replace those books. This section is intended for those who do not have any reference books.

The Bergey Classification of Bacteria

• Bergey Division I = The Cyanobacteria (formerly the blue-green alga) - These bacteria can use light as their energy source under aerobic conditions. The use carbon dioxide and produce oxygen.
• Bergey Division II = The Bacteria (includes the photobacteria and all other classical bacteria) - See the 19 parts below.
• Archeobacteria = in the 8th Edition (1974) the archeobacteria were mixed within the 19 parts of the book. I have not yet decided how to handle these bacteria.

The Bergey Classification of Bacteria into 19 parts.

• Phototrophic Bacteria: Rhodospirillum - Rhodopseudomonas - Chromatium
• Gliding Bacteria: Myxococcus - Beggiatoa - Simonsiella - Leucothrix
• Sheathed Bacteria: Sphaerotilus - Leptothrix
• Budding / Appendaged Bacteria: Caulobacter - Gallionella
• Spirochetes: Spirochaeta - Treponema - Borrelia
• Spiral and Curved Bacteria: Spirillum - Auqaspirillum - Oceanospirillum - Bdellovibrio
• Gram-negative Aerobic Rods and Cocci: Pseudomonas - Xanthanomonas - Zoogloea - Gluconobacter - Azotobacter - Rhizobium - Agrobacterium - Halobacterium - Acetobacter
• Gram-Negative Facultative Anaerobic Rods: Escherichia - Citrobacter - Salmonella - Shigella - Klebsiella - Enterobacter - Serratia - Proteus - Yersinia - Erwinia - Vibrio - Aeromonas - Zymomonas - Chromobacterium - Flavobacterium -
• Gram-negative anaerobes: Bacteriodes - Fusobacterium - Desulfovibrio - Succinimonas
• Gram-Negative cocci: Nisseria - Branhamella - Acinetobacter - Paracoccus
• Gram-negative anaerobic cocci: Veillonella - Acidaminococcus
• Gram-Negative Chemolithotrophic: Nitrobacter - Thiobacillus - Siderocapsa
• Methane producing:
• Gram-Positive Cocci: Micrococcus - Staphylococcus - Streptococcus - Leuconostoc - Pediococcus - Aerococcus - Peptococcus - Ruminococcus - Sarcina
• Endospore-forming Rods and cocci: Bacillus - Clostridium - Sporosarcina
• Gram-positive, non-sporing rods: Lactobacillus - Listeria - Erysipelothrix - Caryophanon
• Actinomycetes and Related: Corynebacterium - Arthobacter - Brevibacterium - Cellumonas - Kurthia - Propionibacterium - Eubacterium - Actinomyces - Archina - Bifidiobacterium - Rothia - Mycobacterium - Frankia - Streptosporangia - Nocardia - Streptomyces - Streptoverticillium - Micromonospora
• Rickettsias: Rickettsia - Erhlichia - Wollbachia - Bartonella - Chlamydia
• Mycoplasmas: Mycoplasma - Acoleplasma - Thermplasma - Spiroplasma
