Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Question: What antibiotics work best in preventing E. coli k12 from growing; amoxicillin‚ ampicillin‚ or ciprofloxacin? Hypothesis: If ciprofloxacin‚ an antibiotic‚ is added to petri dishes covered in live bacteria and left to sit for four to six days in an incubator at 37 degrees Celsius‚ then the petri dishes containing ciprofloxacin will have the largest zone of inhibition out of all of the other antibiotics tested because research shows that ciprofloxacin in one of the strongest antibiotic currently

experiment is to observe how well organisms grow on three different media types such as chemical defined‚ complex‚ selective‚ and differential media. Experimental Methods In this lab‚ we use the procedure from Chemically Defined‚ Complex‚ Selective‚ and Differential Media. We divide the agar plates that have the unknown in third‚ write our initials‚ and date on the bottom of the agar plate. We also divide the agar plates into quadrants‚ label each organism in their quadrant‚ write our initials‚ and

bacteria can use citrate as a source of carbon. To test if the unknown bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface of Simmon’s citrate agar

Lab Report 2 Biological Media Meva Tinsley Georgia State University Lab Report 2 Introduction: Biological Media Microorganisms require nutrients and certain environmental conditions in order to thrive. In the lab‚ we use a Biological Media to aid in growth reproduction. Also referred to as a culture medium‚ a Biological Media is a substance used to support the growth of microorganisms. The two types of media most commonly used in Microbiology are selective media and differential

cause harm‚ society benefits from microorganisms in many ways. Microorganisms are necessary for the production of antibiotics‚ vitamins‚ vaccines and food such as bread and cheese. Dues to its important role in society the study of microorganisms‚ Microbiology‚ has become widespread. Microorganisms collected for study can be grown and visualized in both liquid and solid growth media. The purpose of the media is to provide all of the necessary nutrients for microorganisms to live and reproduce. Although

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate
