Antibiotic Resistance and its Leading Cause Description: There is an accelerated emergence of resistant bacteria developing globally, endangering the efficacy of antibiotics, which have been in use for a long time and have saved millions of lives. Decades later, after the first patient was treated with antibiotics, bacterial infections are now posing a threat Description: The law of conservation states that energy can neither be created nor destroyed but can only be transformed from one form to another.
In the wake of climate change, efforts have been geared towards discerning why the earth's sustainability is declining at an unprecedented rateMost deductions have attributed They can tolerate NaCl concentration upto 5M. High sugar concentration: Osmophilic organisms are capable of living in medium of high sugar concentration; such as Starmerella and Zygosaccharomyces yeasts can sustain in honey and fruit juice concentrates.
The principle bacterial genera include Hydrogenomonas, Leptospirillium, Methanobacter, Methanosarcina, Nitrobacter, Nitrosomonas, Desulfovibrio including remaining genera of Iron and Sulfur bacteria. Prokaryotic cyanobacteria are endolithic. Polluted environment: Microbes usually resist ultraviolet radiation and some were also reported to thrive in nuclear radiation. They are called as radiation resistant microbes Deinococcus radioresistans. Microbes have also been isolated from oil spilled ocean waters Geotrichum, Aeromonas, Rhizopus , soils containing relatively higher concentration of pesticides or from recalcitrant aquatic and soil bodies Veillonella, Micrococcus, Pseudomonas, Serratia.
Sometimes, extremophiles adapt themselves to live in more than one type of extreme conditions; they are termed as polyextremophiles or cosmopolitan Chroococcidiopsis, Thermoacidiphilus. Thermoacidophilic bacteria are able to live in very hot as well as very acidic environment. In all categories of extremophiles, organisms are able to grow, reproduce and survive similarly like other microbes from normal ecosystems. Extremophiles also have important biotechnological applications which are enlisted here: 1. Pharmaceuticals, antibiotics and other novel drugs 2. Surfactants for oil recovery 3. Metal extraction and recovery 4. Coal desulfurization 5. Environmental biosensors 6. Source of heat, cold, alkali and acid resistant enzymes and proteins 7.
Methane production 8. Pigments for electrical generation 9. It has also yielded obligately piezophilic species i. A bit of creative thinking suggests other physical and chemical extremes not considered here, including unusual atmospheric compositions, redox potential, toxic or xenobiotic manmade compounds, and heavy metal concentration. There are even organisms such as Geobacter metallireducens that can survive immersion in high levels of organic solvents such as those found in toxic waste dumps.
Others thrive inside the cooling water within nuclear reactors. While these organisms have received relatively little attention from the extremophile community, the search for life elsewhere may well rely on a better understanding of these extremes. The study of extremophiles holds far more than Guinness Book of World Records-like fascination. Seemingly bizarre organisms are central to our understanding of where life may exist and where our own terrestrial life may one day travel. Did life on Earth originate in a hydrothermal vent? Will extremophiles be the pioneers that make Mars habitable for our own more parochial species? A deep ocean hydrothermal vent belching sulfide-rich hot water. A variety of life forms comprise a food web based on bacteria that live off of the energy provided by the sulfide-rich vent waters.
Happily, extremophile research has a lucrative side. Industrial processes and laboratory experiments may be far more efficient at extremes of temperature, salinity and pH, and so on. Natural products made in response to high levels of radiation or salt have been sold commercially. Glory too goes to those working with extremophiles. At least one Nobel Prize, that for the invention of the polymerase chain reaction PCR , would not have been possible without an enzyme from a thermophile. As the world of molecular biology has become increasingly reliant on products from extremophiles, they will continue be the silent partner in future awards.
Current work on extremophiles in space focuses on four major environments: manned-flight vehicles, interplanetary space because of the potential for panspermia , Mars and Europa because of the possibility of liquid water — and thus life. Mars is, at first blush, inhospitable. Temperatures are, for the most part, frigid, exposure to ultraviolet radiation is high, and the surface is highly oxidizing, precluding the presence of organic compounds on the surface. Yet hydrogeological evidence from Mars Global Surveyor hints that liquid water may even flow today under the surface. Previous evidence seems to show that it once flowed much more freely on the surface in ancient times.
Could Mars harbor subsurface life, similar to the subsurface or hydrothermal communities found on Earth? If so, it would be protected from surface radiation, damaging oxidants, and have access to liquid water. Mars is rich in carbon dioxide, the raw material used by plants to produce organic carbon. This Mars Global Surveyor spacecraft photo shows gullies eroded into the wall of a meteor impact crater in Noachis Terra. It is possible that these gullies indicate that liquid water is present within the Martian subsurface today. With evidence mounting that one or more of the large moons of Jupiter Europa, Ganymede, Callisto have ice-covered oceans, the possibility of life on these moons becomes a subject of scientific discourse.
One of these, Europa, has an ice layer too thick to allow enough light to get through to allow photosynthesis, the process that drives much of terrestrial life including those under the perennially ice-covered lakes of Antarctica. The Galileo spacecraft has detected a weak magnetic field on Callisto, suggesting that salt water may lie beneath an ice-covered surface. Supportive evidence exists as well for an ocean with Ganymede. Space is extremely cold, subject to unfiltered solar radiation, solar wind, galactic radiation, space vacuum, and to negligible gravity. But this treacherous realm can be crossed by life. We know from Mars meteorites such as the now famous ALH sample that a natural vehicle exists for interplanetary transport.
These meteorites contain organic compounds from Mars, showing that such compounds can survive the journey. The criticism that life cannot endure extended periods in space is now being tested experimentally in space simulation facilities in the U. Survivors to date include spores of Bacillus subtilis and halophiles in the active vegetative state. Indeed, by studying the extremophiles here on Earth, we may get the first clear indication of what ET could be like — or at least the range of things they might eat and breathe.
