Eubacteria for repoort.

1. EUBACTERIA
“TRUE BACTERIA”

3. eubacteria
Eubacteria are bacteria known as
prokaryotes. Prokaryotes are organisms that
lack a cell nucleus and other cell parts, and
tend to be less complex. Eubacteria also
possess cell walls made of peptidoglycan, a
chemical that gives their cell wall added
strength.

4. eubacteria
Eubacteria lives in all types of environment
including human body, and reproduce by
binary fission or budding (asexual).

7. Characteristics
Bacteria only has three common forms-
Bacteria is names by shape: rod-shapes-
bacilli, spiral shape-spirilla or spirochetes,
and spiral bacteria-cocci
• No nucleus
• Moves and has cell wall-differentiates
from a plant

11. Species/phylums
Eubacteria kingdom include streptococci which
causes strep throat, as well as the bacteria that
produces yogurt and some types of vitamins.
Eubacteria are usually divided into five phylums:
Spirochetes, Chlamydias, Gram-positive
bacteria, Cyanobacteria (formerly blue-green
algae), and Proteobacteria. There are many
types of bacteria, many of which are extremely
similar, so you may see other groupings.

17. spirochetes
Spirochetes are spiral (“spiro”) shaped
simple, extremely thin bacteria that move like
a corkscrew (with the aid of a flagella).
Chlamydias are intracellular parasites of
animals. They lack peptidoglycan completely
and are therefore gram-negative. It can cause
eye infections and eventual blindnes.
CHLAMYDIAS

18. cyanobacteria
Are photoautotrophs resembling chloroplast;
they even have two photosystems and
chlorophyll. They were once thought to be
plant and are still sometimes referred to as
“blue-green algae.”
Are like proteobacteria, are very diverse
phylum of bacteria. They include
photosynthetic and chemoheterotrophic
bacteria and some, but not all, form spores
GRAM-POSITIVE BACTERIA

19. Purple bacteria
Is the most diverse phylum of bacteria and is
divided into three very different classes: purple
bacteria, chemoautotrophic proteobacteria, and
chemoheterotrophic chemoheterotrophic bacteria
bacteria.
Are photoautotrophs who perform photosynthesis
without releasing oxygen. They are non-water
molecules such as 𝐻2S as a source for there
electons.
PROTEOBACTERIA

20. chemoautotrophic proteobacteria
Are vital part of may ecosystems as many of
them conduct nitrogen fixation (𝑁2 to 𝑁𝑂3
Nitrate).
Are mainly endemic or intestinal bacteria.
Most are rod-shaped, like E. Coli and
Salmonella.
CHEMOHETEROTROPHIC PROTEOBACTERIA

21. adaptations
• Anaerobic Respiration (can do when
need oxygen)
• Swapping of plasmids (bacteria sex)-
makes genetic variation possible

22. Ecological importance
Break down food, make vitamins, keep
harmful microbes away in humans
Some oxygen bacteria produce oxygen
(photosynthesis)
Help recycle carbon, nitrogen, hydrogen,
and sulfur
Some can digest oil-helps clean up oil
spills
