  • Extreme Environment Analysis

    As with all organisms, these different transport systems will probably be of different importance, or function best in specific conditions or triggers (get a reference). In addition to the difficulties associated with maintaining extreme concentration gradients, high concentrations of salt ions can cause problems with protein stability and solubility for both extracellular and cytosolic proteins (Madern, et al. 1999). Proteins specialized for function in high ion concentrations, or halophilic proteins, have been found to contain more acidic amino acids than proteins from non-halophilic organisms, as well as fewer Lysine and aliphatic residues to help counteract these complications (Madern, et al. 1999). Har. marismortui is not the only halophile to incorporate these adaptations, some halophilic bacteria, such as Halobacterium salinarium have also been found to share acidic proteins such as (an acidic shared protein and a reference). Another commonly shared family of proteins among halophilic microorganisms is bacteriorhodopsins, highly studied light-activated trans-membrane proton pumps (Falb, et al. 2008). Har. marismortui’s bacteriorhodopsin shares similar proton donor sites and retinal-binding pockets with other archael proton pumps, but has an extended proton release region that contains additional water. In addition, Har. marismortui’s bacteriorhodopsin also has some novel regions such as a triplet of interhelical hydrogen bonds, which stabilize the protein’s fold,…

  • Which Microbes Prefer To Live Lab Essay

    osmotic pressures have on organisms. Materials used to perform this experiment included: Gloves Culture Medium 2 NaCl Agar plates Cotton tip applicators Bio-hazard disposal Incubator shelf Incubator Following aseptic technique, each organism was streaked across the two labeled plates using a different cotton tip applicator for every streak. Each of the three organisms were spaced appropriately on the agar plates to prevent contamination. The amount of NaCl or “salt” in one plate was 1%…

  • Microbes Research Paper

    However, some microbes are larger enough to be seen without microscope. According to Schaechter et al (2005), the smallest bacteria that has been found have barely 0.2 μm long, and the size of giant bacteria and protozoa is approximately 1 millimetre (mm) in length or even longer. Some of microbes have ability to live under harsh physical conditions and can only survive under extreme conditions which make them as an essential organism in supporting all environments on Earth (Schaechter et al…

  • Eubacteria Essay

    through binary fission meaning it duplicates its genetic material and then divides into two parts. Bacteria can also exchange genetic material through conjugation, when DNA is directly transferred from one bacterial cell to another, the two bacteria then merge and share the genetic material. There are two bacterial kingdoms of prokaryotes, the Archaebacteria and the Eubacteria. Archaebacteria was the first prokaryotes, being very ancient, and exist in very extreme conditions not to mention…

  • What Is Magnetic Resonance Imaging?

    Magnetic Resonance Imaging (MRI) is a medical technology that uses magnetic fields to interact with protons in the human body, producing an image that allows doctors to diagnose disease and/or injuries (DiGiuseppe, Haberer, Salciccioli, Sanader, & Vavitsas, 2012). The idea of MRI technology had come from Raymond Damadian who was a medical professor and had founded the company that manufactured MRI scanners (Bergman PH. D, 2015). In the beginning, Damadian had been using Nuclear Magnetic…

  • We Organism B And Enterobacter Aerogenes

    Earth. Using sequence match through the Ribosomal Database Project, the rDNA of four organisms were analyzed. The report produced information on the organism, including the domain, family, genus, and species. An s_ab score is given, indicating the similarity of sequences. Each of the four organisms received a s_ab score of 1.000, proving that the inputted sequence was identical to the sequence of the species determined. Once the species was determined, an extensive literature review of each…

  • Essay On Archaea

    lineage in the archaeal phylogeny (Brochier-Armanet et al., 2008b). One species of Thaumarchaeaota that has been studied has some biologists thinking the organisms are ammonia-oxidizers to help the nitrogen and carbon cycles operate for the crucial Earths environment. These creatures also included the topic of a medicinal or therapeutic reaction a person may get while interacting with these archaea. Some hot springs enthusiasts get this feeling of well-being from the mineral enriched…

  • Archaea And Eukaryotes

    (bacteria and archaea) is that both transcription and translation of the genetic message are performed in the same cell compartment and occur consecutively. This creates the conditions in which these processes can be coordinated through different mechanisms specific to those of eukaryotic organisms. Another characteristic which should be considered in identifying archaea prokaryotes and bacteria prokaryotes are metabolic differences. This allows us to determine differences in classifying…

  • Alexander Fleming Kills Bacteria

    It is one of the oldest life form on earth. Unlike, other life forms bacteria is a major contributor to earth ecosystem and it is also essential to human life. Its characteristics are differences from many other living life forms. One of its characteristics includes adaptability, it can be found almost anywhere, such as soil, the air, water, and on the human body. It has the ability to thrive in any environment to include extreme environmental conditions that will not hinder its growth. Because…

  • Describe Two Ways In Which Infectious Bacteria Cause Disease

    an even more antibiotic resistant population. Why is antibiotic resistance an issue? Antibiotic resistance bacteria do not respond to antibiotics, making antibiotics ineffective, and greatly limiting the options of disease treatment. How long ago were Archaebacteria first discovered? Carl Woese, a microbiologist, discovered Archaebacteria in 1977. What are the four types of Archaebacteria (group Euryarchaeota)? List their key features including habitat. Group Key Features Methanogens Habitat:…
