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.Continue Reading
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
Examples of beneficial bacteria, commonly referred to as probiotics, include lactobacillus, bifidobacterium, streptococcus and bacillus coagulans. These bacteria all perform functions similar to those that naturally occur in the human body.Full Answer >
Purple and green bacteria and cyanobacteria are photosynthetic. Photosynthetic bacteria are able to produce energy from the sun's rays in a process similar to that used by plants. Instead of using chlorophyll to capture the sun's light, these bacteria use a compound called bacteriochlorophyll.Full Answer >
Autotrophic bacteria include cyanobacteria, green sulfur bacteria, purple bacteria, halophiles and methanogens. These bacteria, along with several types of plants and fungi, have the ability to produce their own food through photosynthesis. They use light, water and carbon dioxide or other chemicals to transform sunlight into glucose — a type of sugar then used for energy.Full Answer >
Some examples of biotechnology include human gene therapy, genetically modifying plants and changing the genes of bacteria. Biotechnology helps improve crops so they produce more, healthier produce. It also helps fight human diseases.Full Answer >
