EUBACTERIA
BY: Jake King
Eubacteria AKA “True Bacteria”
• Are prokaryotic cells(they lack a nucleus) that are very common in
the daily of humans
• Can be found almost anywhere and kills thousands of people each
year
• They serve as antibiotic producers and digest food in our stomachs
• We also use them for producing drugs, wine, and cheese
• Apart of the domain kingdom
• Reproduce with the simple process of binary fission(divide in half)
Categories
• Eubacteria are divided in five phylum's: Spirochetes, Chlamydias,
Gram-positive bacteria, cyanobacteria and Proteobacteria
Characteristics
• Prokaryotic cell
• Lack mitochondrions or chloroplast
• has a rigid cell wall composed of peptidoglycan
• If there’s flagella present its made of a single filament of the
protein flagellin
• The cell membrane is composed of phospholipids bilayers that lack
cholesterol and steroids
• Asexual reproduction
• Many eubacteria form spores to be resistant to dehydration, and
handle most temperatures when no food is present(last up to 50
years)
• Are either spirilla(spiral shaped), bacilli(rod shaped, or
cocci(spherical)
Types of Eubacteria
• Heterotrophic, Autotrophic, and Chemotrophic
• Heterotroph's are able to absorb organic materials down in both
living and dead organisms(can live anywhere basically, including as a
parasite inside of the human body)
• Autotroph’s can make their own food by photosynthesis( have a
blue and green color due to chlorophyll and live in ponds, lakes and moist
regions)
• Chemotrophs acquire their food by breaking down inorganic
matter(dead organisms)
Eubacteria
Classification
• Eubacteria is divided into categories based upon how they acquire
nutrition
Mode of Nutrition

CO2
chemoautotroph
Inorganic chemicals

Binary fission
• Binary fission- a method of
asexual reproduction in unicellular
organism by division into two
daughter cells
