  • Microbiology Lab Reports

    Sara Parks Unknown Report Introduction One of the many reasons to study microbiology is to gain a better understanding of microorganisms and the huge part they play in the world. It is imperative to know the differences between microorganisms. This knowledge is useful in many cases; for instance, a patient with an unidentified infection could be administered effective treatment if one possessed the knowledge to correctly define the microorganism. Furthermore, the purpose of this unknown…

  • Which Microbes Prefer To Live Lab Essay

    This lab experiment was completed to determine the environment in which microbes prefer to live. The pH, moisture, available nutrients, oxygen and light all affect the rate in which bacteria grow. The majority of bacteria flourish when the pH level is near neutral; the growth rate is highly affected if the pH is off by just a little. If too acidic, the amount of time it takes the bacteria to adjust to a new environment (lag time) is increased which slows the growth, the activity of enzymes is…

  • L-Ornithine Research Paper

    1. Introduction L-Ornithine is an important chemical ingredient for its applications in food and pharmaceutical industries as a dietary supplement, as it is known to be efficacious in the treatment of liver diseases and wound healing [11]. It can also be used as a precursor for the synthesis of other amino acids, such as arginine and citrulline, and putrescine, an important diamine used as a nylon precursor [28]. L-Ornithine could be produced by fermentation using auxotrophic mutants, for…

  • Metal Resistance Essay

    al., 2011). These characteristics of siderophore are arises due to its ligand functionalities and with the help of this property siderophores may have a strong binding affinity or selectivity to metal other than Fe (Hernlem et al., 1999). Pseudomonas aeruginosa secrete the pyochelin siderophore and could chelate various types of metals, e.g. Ag+, Al3+, Cd2+, Co2+, Cr2+, Cu2+, Eu3+, Ga3+, Hg2+, Mn2+, Ni2+, Pb2+, Sn2+, Tb3+, Tl+ and Zn2+ (Braud et al., 2009a). Both types of siderophore (Phyto and…

  • Bacillus Cereus Lab Report Answers

    appeared clear with an outline, and the spores that were seen appeared as black dots. c. The first test performed was the gram stain, the purple color indicated that it was gram positive, this removes all gram negative possibilities including Pseudomonas aeruginosa, Klebsiella pneumonaie, and Proteus vulgaris. Since I also observed that the bacteria were rod shaped, it excluded the cocci specimens Staphylococcus aureus and Streptococcus pyogenes. After performing the spore stain and noticing…

  • Antimicrobial Properties Of Silver Nannoparticles

    from the soils of Bikaner, Rajasthan and was added to a mixture of silver nitrate to form silver nanoparticles [5]. The AgNPs synthesized were found highly toxic against many different multi-drug resistant human pathogens: Escherichia coli, Pseudomonas aeruginosa, and Streptococcus aureus. These silver nanoparticles even exhibited greater antibacterial activity than standard antibiotics [5]. This investigation showed how bacterial endospores have the potential of being excellent bactericidal…

  • Pathogens: A Cause Of Infectious Disease

    “You can find bacteria everywhere. They 're invisible to us. I 've never seen a bacterium, except under a microscope. They 're so small, we don 't see them, but they are everywhere” (Bonnie Bassler). Pathogens can be found all around us. Over 160,000 people die each year in the United States from infectious diseases that Pathogens cause. Pathogens can be traced from decades ago even during the geologic time. Many pathogenic organisms show ancestral traces in the fossil records from hundreds of…

  • Biochemical Unknown Lab

    Biochemical Unknown I. Introduction Cultural Characteristics or morphology and biochemical tests can be used to identify and classify microorganism. By culturing microorganism in nutrient broth, slants, and on nutrient agar plates, the cultural characteristics or morphology can be determined. In this lab, the test tube 2 was incubated in a nutrient broth. The pigmentation of the tube was yellow. The media for test tube 2 was turbid. There were a few sediment on the bottom of the broth. In…
