Managing Microbes in Space Background (HS) You've probably experienced it before: that miserable feeling of something making your intestines cramp and making you very ill. Fortunately, that misery usually only lasts a relatively short time because our bodies have a great immune system that is very good at defending us from pathogens. But. about microbes to support space exploration? One interesting thing about Microbiology relevant to spaceflight is that . microbes help keep us alive and are essential for human-led space exploration! Microbes play a major role in maintaining human health. • Microbes help to detoxify compounds and can help reduce stress on host tissues

Skylab focused more on microbes with possible human health effects. With the launch of the ISS, it was understood that this new built environment would be permanently housing microbes as well as humans. Calls were made for a better understanding of microbial ecology and human-microbe interactions during extended stays in space (Pierson, 2007 environments, such that microbes will be in competition for the limited components. As they grow and producemore biomass, microbialgroups expand in space and competewith Trends Microbes express many competitive phenotypes in the presence of others; exploitative phenotypes include meta-changes that increase growth rates or molecule secretion to.

The results are compared with the values such a microbes), some of which are descendants of the earliest lifeforms on Earth. Scientists think that during the first three billion years of Earth's history, microorganisms transformed the original, anoxic (without oxygen) atmosphere into something that could support complex forms of life. Microbes harnessed energy stored in chemicals such as iro SUMMARY The responses of microorganisms (viruses, bacterial cells, bacterial and fungal spores, and lichens) to selected factors of space (microgravity, galactic cosmic radiation, solar UV radiation, and space vacuum) were determined in space and laboratory simulation experiments. In general, microorganisms tend to thrive in the space flight environment in terms of enhanced growth parameters.

Background: The International Space Station (ISS) represents a unique biotope for the human crew but also for introduced microorganisms. Microbes experience selective pressures such as microgravity, desiccation, poor nutrient-availability due to cleaning, and an increased radiation level. We hypothesized that the microbia 1.2 Useful Microbes A yogurt making experiment is the key to this activity in which students learn that microbes can be useful. 1.3 Harmful Microbes Close examination of various illnesses illustrates to students how and where bad microbes cause disease.

Their first year of funding comes from the NASA. Phytoremediation is the process by which plants and their root microbes remove contaminants from both air and water. Those purifying properties have been discovered within the frame of space habitation experiments: in the 1980s, scientists at the John C. Stennis Space Center shed light on interior plants' ability to remove volatile organic chemicals (VOCs) from tightly-sealed chambers Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 10 14 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function

Gnotobiotic Life. The concept of animals existing in complete isolation from microorganisms originated with Louis Pasteur , who also predicted that an animal's existence would be impossible without microbial life.Ten years later, George Nuttal and Hans Thuerfelder disproved Pasteur's prediction by removing microorganisms from a guinea pig .Much later, James Reyniers and colleagues reared rats. The branches of microbiology can be classified into pure and applied sciences. Microbiology can be also classified based on taxonomy, in the cases of bacteriology, mycology, protozoology, and phycology. There is considerable overlap between the specific branches of microbiology with each other and with other disciplines, and certain aspects of these branches can extend beyond the traditional. Extraterrestrial life is hypothetical life that may occur outside Earth and which did not originate on Earth. Such life might range from simple prokaryotes (or comparable life forms) to intelligent beings and even sapient beings, possibly bringing forth civilizations that might be far more advanced than humanity. The Drake equation speculates about the existence of sapient life elsewhere in. Odontogenic infections are generally polymicrobial and from endogenous oral flora. They are mixed aerobic/anaerobic with 60% caused by anaerobic and aerobic bacteria, 35% by aerobic bacteria, and 5% by anaerobic bacteria only. Of the aerobic group, Streptococci comprise about 90% and Staphylococci about 5%. In the anaerobic group, gram-positive. Coliform bacteria are found in soil, surface water, on plants, and in the intestines of warm-blooded animals and people. One type of coliform bacteria called Escherichia coli (E. coli) is a sign that fecal waste is in the water. Some types of E. coli in drinking water can make you sick

Fungal and bacterial microbes are known to mimic mammalian cytochrome P450 metabolism. Traditionally, microbial biotransformation screening and small scale-ups (<1 liter) are performed in shake-flask reactors. An alternative approach is the use of hollow fiber cartridge (HFC) reactors. The performance of HFC reactors is compared with shake-flask reactors using diclofenac as a model substrate mandatory microbial monitoring and observational studies of spacecraft and space stations have been conducted by traditional culture methods, although it is known that m any microbes cannot be cultured with standard techniques. To fully appreciate the true number and diversity of microbes that survive in the ISS, molecular and culture-base grew 13-times faster on the space station than on Earth [7]. Overall, such data indicate that physiologic alterations of normally, non-lethal bacteria and viruses in space may change the health of astronauts in unpredictable manners during space voyages between planets, asteroids, and stars
