The document summarizes several bacterial phyla: - Korarcheota are found in hydrothermal environments and have unique 16S rRNA sequences. - Euryarchaeota include methanogens and extremophiles and are identified by their rRNA. - Crenarchaeota are hyperthermophilic and use sulfur reduction in acidic environments. - Nanoarchaeota are the smallest organisms and live in high temperatures. - Cyanobacteria perform photosynthesis and nitrogen fixation and are diverse. - Spirochetes have helical shapes and internal flagella and reproduce through binary fission. - Proteobacteria include both anaerobic and aerobic organisms and some are pathogenic.

1. Bacteria
Korarcheota:
Korarcheota is a phylum under the domain Archae. This
particular phylum is said to not belong to the main lineage of the
other archaeal group because of their 16S rRNA. These
organisms are said to be found in hydrothermal environments,
high temperatures. In addition, these organisms are found in
small group or by themselves. Also, a new phylum therefore
many of the characteristics of these organisms are still being
discovered.
Euryarchaeotes:
Euryarchaeota is a phylum located in the Archae domain. The
majority of organisms within this phylum are methanogen, produce
methane as a metabolic outcome, but they can also be halophiles
or thermoacidophiles. In addition, these organisms are typically
found in the intestines and can survive in extreme salt
concentrations. Also, these organisms can range from anaerobes,
living without oxygen, to aerobes, living with oxygen. One of the
main characteristics of this group is it rRNA sequences.
Crenarchaeotes:
Crenarchaeotes is a phylum under the domain Archae. The organisms in this group are
hyperthermophiles, can survive in high temperature conditions. In addition, the
environments that these organisms live in are very acidic with a pH as low as one.
Also, these organisms use hydrogen as a basis of electrons to reduce sulfur; the
reduce sulfur allows these organisms to get the energy they need to synthesize food
from carbon dioxide. Moreover, these organisms lack histones, differ in rRNA
sequencing and are found in the marine which are all major characteristics of these
organisms.

2. Nanoarchaeotes:
Nanoarchaeotes is a phylum off of the domain Archae.
The organisms that make up this phylum consist of
organisms that can survive in high temperatures. In
addition, these organisms are small and known as the
smallest organism in the world. Also, these organisms
are made up of only around a thousand based pairs of
DNA. Moreover, a specific way of identifying these
organisms is by their specific rRNA sequence.
Archae
Cyanobacteria:
Cyanobacteria is a phylum in the Bacteria kingdom; many time
these organisms are referred to blue-green algae. All of these
organisms obtain their energy through photosynthesis; however,
these organisms did not always complete the process of
photosynthesis but rather developed the system through evolution.
Also, since these organism use photosynthesis, they have
chloroplast to help with this process. In addition, these organisms
complete the process of nitrogen fixation and the use of the thick-
walled heterocysts that hold enzyme nitogenase. Moreover, these
organisms are very diverse and live in a variety of environments
throughout the Earth.

3. Spirochetes:
Spirochetes are a phylum that is a part of the Bacteria
kingdom. This phylum’s organisms shape is long, helically coiled;
the lengths of these organisms range from five to two hundred
and fifty µm and a diameter of one tenth to six tenth µm. In
addition, the location of the flagella “runs lengthwise between
the bacterial inner membrane and outer membrane”, is one of
the most important characteristics of this phylum. Also, these
organisms reproduce through binary fission. In addition, the
majority of the organisms in this phylum are free-living and
anaerobic, but there are many exceptions.
Proteotic Bacteria:
Proteotic Bacteria is a phylum that is a part of the Bacteria
kingdom. This phylum is rather large and contains organism
that are grand negative. One of the interesting facts about this
phylum is that the organisms can be anaerobic, survive living in
oxygen free environments, or aerobic, live in environments with
oxygen. Many of these organisms are free-living and parasitic;
therefore, many of these organisms cause diseases, such as E.
coli.
Chlamydias:
Chlamydias is a phylum that is a part of the Bacteria kingdom.
Also, these organisms are parasitic and can only survive in
animal cells; these organisms depend on the host ATP to
survive. Another characteristic that is a part of this phylum is
the lack of peptidoglycan which could result from the gram-
negative walls.

4. Gram-Positive Bacteria:
Gram-Positive Bacteria is a phylum of the Bacteria kingdom.
Some of the species in this phylum are capable of forming
colonies, such as actinomycetes. Also, many of these organisms
are free-living. In addition, many times these organisms are tiny
and have few genes. Moreover, many of the organisms that have
cell walls which encompass teichoic acids and peptidoglycan
which causes the organisms to look violet or blue. However, not
all of the organisms in this phylum have a cell wall. Other
characteristics that make up this phylum include cytoplasmic lipid
membrane, a thick peptidoglycan layer, a capsule of
polysaccharides, and flagella.
