Bacteria are among the most numerous organisms on earth, explains Microbe World. Bacteria exists virtually everywhere on earth. Bacteria can be found in the air, soil, water, on plants, on animals and even on the skin of human beings.
Part of what makes bacteria so plentiful is their ability to inhabit a variety of different types of environments. Some bacteria thrive in extremely hot environments, such as those found in boiling-hot sulfur springs and geysers. Other types of bacteria are capable of surviving sub thermal freezing temperatures buried under many sheets of ice, such as those conditions found in the super-cold Antarctic lakes. Microbes that live in these extreme conditions are called extremophiles.
One single teaspoon of top soil contains as many as one billion bacteria cells. The human mouth alone harbors more than 500 different species of bacteria. Each square centimeter of skin on the human body contains around 100,000 bacteria. Bacteria can survive not only in extreme conditions, they can also survive on surfaces for long periods of time. While removing bacteria from day-to-day life is not feasible, washing hands regularly and disinfecting surfaces you come in contact with on a regular basis helps reduce the amount of bacteria that enters your body.Learn More
According to Scientific American, peptidoglycan is the substance that makes up the cell walls of bacteria. The polymer is primarily composed of amino acids and sugars. Peptidoglycan is a crucial component of bacteria, and it influences several different facets of their biology. Scientists use differences in the peptidoglycan-based cell walls to classify different bacterial species.Full Answer >
Thermophilic bacteria are microorganisms found in areas that have temperatures too high for other types of bacteria. These bacteria live, reproduce and thrive in temperatures ranging from 113 degrees to more than 212 degrees Fahrenheit.Full Answer >
Spirilla bacteria are Gram-negative bacteria that may cause bacterial diarrhea, adenocarcinoma and peptic ulcers.These bacteria are one of several varieties of bacteria that cause illness or disease in humans; mycoplasmas, chlamydiae, spirochetes and mycobacteria are other virulent and potentially destructive organisms. Spirilla bacteria are identified by their unique body shapes, which resemble spiral pasta noodles, and the type of physical harm that they cause to humans.Full Answer >
Some bacteria that use flagellar movement include vibrio, spirillum, klebsiella, pseudomonas, azospirillum and salmonella. Bacteria that utilize spirochaetal movement include the borrelia, treponema, leptospira, cristispira and spirochaeta. A few examples of the gliding bacteria include achroonema, alysiella and cyanobacterium Oscillatoria. Bacteria motility falls under three categories: flagellar, spirochaetal and gliding.Full Answer >
