What is microorganisms and study of microorganisms called 2 See answers karina9853 karina9853 Answer: A microorganism, or microbe,is a microscopic organism, which may exist in its single-celled form or in a colony of cells. These microbes commonly make use of carbohydrates, lipids, and proteins, although many microbes can metabolize other organic compounds such as hydrocarbons. Curiously, NASA has also built microgravity simulators to study space bacteria without leaving Earth. Space science encompasses all of the scientific disciplines that involve space exploration and study natural phenomena and physical bodies occurring in outer space, such as space medicine and astrobiology.. Could it be a show-stopper for long-duration space travel? This study may provide key factors to expanding our fragile horizon into space, while expanding the knowledge base for how the human body's microbiome functions. The biological characteristics of microorganisms can be summarized under the following categories: morphology, nutrition, physiology, reproduction and growth, metabolism, pathogenesis, antigenicity, and genetic properties. Could an extended period of spaceflight create an influx of disease-causing germs known as pathogens, or affect a crew member's ability to fight off a disease? It can be a speck of dirt or an entire planet. Immunology, the study of the immune system, is often included in the study of microbiology because host–pathogen interactions are central to our understanding of infectious disease processes. Eukaryotic microbes are generally aerobic. With the potential to affect future space exploration missions, researchers funded by NASA's Human Research Program plan to gather and analyze biological samples to study better the space station's Microbiome - the ever-changing microbe environment that can be found on the space station and its inhabitants. Expedition Six Flight Engineer Don Pettit uses a chemical/microbial analysis bag to collect water samples from the Potable Water Heater in the Zvezda Service Module on the International Space Station. Microorganisms vary widely in terms of the physical conditions required for growth. The first of these four types of micro-organisms may either be free-living or parasitic . As is the case in many sciences, the study of microorganisms can be divided into two generalized and sometimes overlapping categories. Microorganisms that require free oxygen for their growth are called aerobic organisms, ... Microorganisms used in this study were obtained from a chemostat. Many microbes play important roles in the delicate balance of different biological environments, or ecosystems. The microorganism must be present in every case of the disease but absent from healthy organisms. In TEM the electron beam passes through the specimen and registers on a screen forming the image; in SEM the electron beam moves back and forth over the surface of microorganisms coated with a thin film of metal and registers a three-dimensional picture on the screen. Water and air aboard the station are filtered, and microbe levels (including on surfaces) are regularly sampled and monitored. For example, humans naturally carry Staphylococcus aureus (more commonly known as "staph"), so it's not surprising that this bacterium has been found on surfaces and in the air on the station where crew members live and work. The experiment also is investigating another benefit of growing plants in space: the non-nutritional value of providing comfort and relaxation to the crew. This field can be further classified into the following subfields: Plant microbiology and plant pathology – The study of the interactions between microorganisms and plants and plant pathogens. This increase is possible because the wavelengths of the electron beams are so much shorter than the wavelengths of light. Medical microbiology: The study of the role of microbes in human illness. A microorganism, or microbe, is a microscopic organism, which may exist in its single-celled form or a colony of cells.. Bacteria in space may sound like the title of a bad science fiction movie, but it's actually a new experiment that tests how the weightlessness of space can change microbes' antibiotic resistance. Other physical conditions that affect the growth of microorganisms are acidity or basicity (pH), osmotic pressure, and hydrostatic pressure. Lab time and space on the ISS are so hard to come by, says Ott. A crew member's diminished immune system also can make infection more probable, so precautionary measures are put in place to protect them.
