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
Examples of saprophytic bacteria include cheese mold, lactic acid, yeast and rotting kitchen waste. Saprophytic bacteria are fungal organisms that feed off of decaying organic matter. The term "saprophyte" refers specifically to fungal and bacterial saprotrophs, but animal saprotrophs are known as saprozoites.Full Answer >
Examples of facultative anaerobic bacteria include salmonella and E. coli. Facultative anaerobic bacteria are members of the taxonomic families Enterobacteriaceae, Vibrionaceae and Pasteurellaceae. Many of the species in these families are pathogens in humans, other animals or plants.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 >
Examples of non-lactose fermenting bacteria include salmonella, shigella, proteus and pseudomonas aeruginosa. These microorganisms can be differentiated from lactose-fermenting bacteria by using differential bacteriological media, such as MacConkey agar and eosin-methylene blue agar, or EMB.Full Answer >
