  • Isolation of Microorganisms from Environmental Samples

    in digestion and provide vitamins. Some microbes can also be antagonistic or harmful to humans‚ and when scientists isolate them‚ they can study and identify ways on how to counteract the microbes harmful effects. This exercise aims to isolate microorganisms from a variety of environmental samples and to enumerate the different microbial species observed. Methodology Results and Discussion Bacteria‚ molds and yeast have different colony morphologies and characteristics that are specific to

    Unknown Microorganism: #5 Report Callie Schalk Microbiology Professor Quave November 24‚ 2015  The unknown microorganism #5 is Pseudomonas aeruginosa. It can survive in a variety of environments and at temperatures found in clinical settings (Murray et al‚ 1999). Clinical setting is referring to temperatures such as those in the hospital environment. P. aeruginosa can also survive in aqueous environments. Pseudomonas aeruginosa is found at several different sources. Nosocomial

  • MicroOrganism

    Unknown Experiment Introduction: The purpose of this experiment is to distinguish and indentify an unknown bacterium. There are several tests that can help one eliminate and narrow down the options. The most useful test‚ and the very first one done‚ is a gram stain. This test will tell whether the bacterium is gram-positive or gram-negative. After the type of gram stain is identified‚ the tester has a wide array of differentiating tests at their disposal. Based on the results from these

  • The Effects of Herbicides on Paramecium

    to aquatic organisms. The organisms used were protists and bacteria which are microscopic organisms (Microorganisms). Herbicides are chemicals used to control certain plants such as weeds. Two hypotheses were tested in the experiment.H₁) The herbicides will affect the population growth rate of the microorganisms and H₂) The adding of herbicides will affect the general behavior of the microorganisms negatively. Each species were separated into their own six containers‚ four of which had chemicals
