Where is E. coli found?
It is classified into the Proteobacteria phylum. It is rod-shaped and Gram-negative, so it has an additional membrane surrounding its cell wall. E. coli is commonly found in the gut of many different types of warm-blooded hosts, including humans – though it can become pathogenic under the right conditions. Most strains are harmless (and possibly beneficial), but some can cause food poisoning and other illnesses. The bacteria can only survive outside of a host for a limited time.
What are the three shapes of bacteria?
Bacteria commonly take on one of three shapes: bacilli, cocci, and spirilla. Bacilli have a rod shape, cocci have a spherical shape, and spirilla have a spiral or wave shape. Their shape was often used as a classification system until recent DNA studies cast doubt on these classifications.
What are plasmids in bacteria?
Plasmids are also found within bacteria separate from the bacteria’s circular DNA. Also referred to as “replicons”, plasmids are autonomous replicating DNA molecules. Essentially, these small rings of DNA allow bacteria to transfer genes between organisms.
Where does DNA float in a bacterium?
Bacterial DNA floats freely within the cytosol, though it is concentrated in the nucleoid. Bacterial chromosomes are often circular but can also be linear in shape. This shape comes in handy when a bacterium is undergoing replication. Bacteria can asexually reproduce through binary fission or budding.
Do eubacteria have a membrane?
Eubacteria, or microorganisms lacking a defined membrane nucleus, have several general characteristics. As prokaryotes, they do not have any membrane-bound organelles. Most eubacteria are enclosed by a cellular wall, which is made up of peptidoglycans in a cross-linked chain pattern. This gives the wall of the bacteria the strength needed to maintain its shape and size through changing environments. Small molecules can diffuse through the cell wall, but larger molecules and ions need carrier proteins and channel proteins to enter the cell.
Can bacteria survive outside of a host?
Most strains are harmless (and possibly beneficial), but some can cause food poisoning and other illnesses. The bacteria can only survive outside of a host for a limited time. Streptococcus pneumoniae, abbreviated to S. pneumoniae is another common eubacteria. It belongs to the Firmicutes phylum.
Classification of Bacteria
Taxonomy is the science of classification. Historically, taxonomical classification was based on observable characteristics. The advent of advanced molecular biological techniques allows for the classification of organisms based on quantifiable genealogical relationships.
Cell Membranes
Plasma Membrane : Plasma membranes are essential structures of all cells. These membranes encapsulate the cytoplasm. Plasma membranes are composed of lipids and proteins. Most lipids in the plasma membrane are phospholipids. These amphipathic lipids are composed of a hydrophilic head group and a hydrophobic tail.
Internal Structures
Cytoplasmic Matrix: The watery substance within the plasma membrane is called the cytoplasmic matrix.
External Components
Several external structures exist outside the cell wall. These include fimbriae, sex pili, and flagella.
Morphology
Members of domain Eubacteria vary in size and shape. The most common shapes are cocci and bacillus. Cocci are spherical cells that may exist singularly or in clusters. Some iterations of cocci include pairs of spherical cells, long chains, or clusters. Bacillus refers to rod-shaped bacteria.
Where are Eubacteria Found?
Bacteria are ubiquitous in our world. They form an important part of every food chain and biosphere. Bacteria play a central role in decomposition. They break down larger organic matter into elements necessary for life, including carbon and nitrogen. These elements are then able to re-enter the food chain.
Metabolism
Bacteria display an array of different metabolisms that allow them to thrive in many different environments. Energy and carbon sources are needed for metabolism: energy fuels the construction of biochemical molecules from carbon precursors.

Where do bacteria live?
Although bacteria may appear simple, they excel in the diversity and complexity of their metabolic capabilities and they are able to survive in many places. Bacteria are found everywhere on Earth where life is able to exist. They are plentiful in soils, bodies of water, on ice and snow, and are even found deep within Earth's crust. They often take advantage of living in and on other organisms in symbiotic relationships and can be found inhabiting the intestinal tracts and surfaces of animals, including humans. For the most part, the bacteria in and around us bring us more benefit than harm. Sometimes however, bacteria can be pathogenic, or disease causing. This can happen for a number of reasons, such as when the host has a compromised immune system or when a bacterium acquires genes that make it grow more aggressively or secrete toxins into its host environment.
When did bacteria first appear on Earth?
Whether primitive life originated on Earth or elsewhere, current consensus is that bacteria were present on Earth 3.8 billion years ago .
How do bacteria get their energy?
Bacteria show an incredible range of metabolic diversity. Some bacteria can get their energy from light (these are referred to as phototrophic organisms), organic compounds (organotrophic), or inorganic compounds such as hydrogen (H 2 ), sulfur compounds (H 2 S), inorganic nitrogen compounds or ferrous iron compounds (chemolithotrophic). Some bacteria can make all of their organic compounds by fixing carbon (autotrophic), while others need to break down organic compounds to provide a carbon source (heterotrophic). Many bacteria are capable of fixing atmospheric nitrogen as a nitrogen source, in addition to organic and inorganic sources of nitrogen. Because of this metabolic diversity, bacteria play an important role in biogeochemical cycles such as the carbon, nitrogen, and phosphorous cycles.
What are bacteria that use oxygen called?
Bacteria that use oxygen are called aerobes. Those that do not are called anaerobes.
How do bacteria reproduce?
Reproduction in bacteria involves duplicating the genetic material and dividing the cell into two daughter cells, a process known as binary fission. Under very favorable conditions, certain bacterial cells can divide as often as once every twenty minutes. Some bacteria, such as Clostridium and Bacillus species, possess the ability to form a resting state, or "spore," when unfavorable conditions are encountered. These spores are very resistant to heat, drying, radiation, and toxic chemicals. Bacterial spores have reportedly been reawakened from a 250-million-year-old salt crystal that existed before the time of the dinosaurs. Sterilization techniques used in medicine must overcome these resistant properties.
Why are bacteria important to the biogeochemical cycle?
Because of this metabolic diversity, bacteria play an important role in biogeochemical cycles such as the carbon, nitrogen, and phosphorous cycles. This metabolic diversity also permits them to occupy a wide range of habitats. Bacteria can thrive in extremes of temperature, pH , salt, pressure, or toxic substances.
How big are eukaryotic cells?
