Nitrosomonas and iron bacteria are the most common examples of chemoautotrophic bacteria because they are able to produce energy through a chemical process, according to Dr. John W. Kimball. These organisms are unique because they are able to produce the energy they need without photosynthesis.Know More
Most organisms on the earth need photosynthesis to survive and to produce the energy they need to function. Chemoautotrophic organisms do not need these processes because they are able to oxidize the electron molecules that they take in from their own internal environments in order to survive. They do not live on anything other than molecules and are able to sustain themselves through the use of these electrons.
Chemoautotrophic bacteria are at the bottom of the food chain. They do not eat anything or take anything in other than at a molecular level and are essential to the survival of small sea creatures. Chemoautotrophic bacteria are responsible for methane, hydrogen gas and carbon monoxide that are found in the ocean. These gasses are a result of what happens when the chemoautotrophs convert the electrons to energy. Some chemoautotrophs, like the iron bacteria, are responsible for everyday things like the rust-colored stains that are often found on the inside of a toilet tank.Learn more about Biology
A microbicidal agent kills microorganisms such as bacteria, while a microbiostatic agent only prohibits the growth of such microorganisms. In the presence of microbiostatics, the microorganisms eventually die due to lack of reproduction. Microbicidals are irreversible and lethal, while microbiostatics are reversible.Full Answer >
Biochemical tests are the quickest and easiest tests for identifying bacteria because they use deductive principles to reduce the number of possible species present very quickly. Additionally, because bacteria are microorganisms, visual identification is not always possible, and is never easy. Genetic testing is possible for some well-known bacteria, but it is expensive and time consuming.Full Answer >
One of the only decomposers that is able to survive in the desert is bacteria because they are tiny and can survive in the air. Other decomposers, such as millipedes, earth worms and beetles, also live in the desert, but they have a difficult time surviving because they depend on moist areas.Full Answer >
Microbiological contaminants are infectious materials, such as bacteria, mold, fungi and viruses. These contaminants, which are often found in food and water, can cause serious illnesses.Full Answer >
