Procedure 3: Nitrogen Fixation Bacteria are important to humans for a variety of reasons. They are responsible for breaking apart dead organisms, as decomposers, and returning the materials to the soil to be used to build more bodies of living things. They can be a source of illness for humans and other forms of life. All life on earth is dependant on bacteria to trap molecular nitrogen from the air and convert it to other nitrogen molecules through a metabolic process called "nitrogen fixation". Once nitrogen has been fixed in this way it is available to plants and can be absorbed from the soil. Plants will use these compounds to build proteins, which then become part of the food chain for all other life on earth. These important nitrogen-fixing bacteria live at the roots of certain plant types. Their presence adds nitrogen rich compounds to the soil. 1. Examine the display at the counter. What type of plants support the growth of these bacteria at their roots? 74 A. B. Bacteria Exercise 9 UAE

TSI Test plz answer all questions Why does TSI contain less glucose than sucrose or lactose? Does an acidic slant indicate that the microbe is a coliform? Explain your answer. What is the function of iron in this medium? Production of H2S by bacteria growing anaerobically in the intestines is common. Some H2S is absorbed into the circulation and some is expelled as intestinal gas. Less commonly, in certain individuals, H2S producing bacteria can live in the plaque built up around their teeth.

TOPIC : MICROBIAL GROWTH Classify the bacteria that is most likely involved in each situation provided according to their classification (as to microbial growth requirements). CHOICES: A. Obligate aerobe ,B. Obligate anaerobe, C. Microaerophile, D. Aerotolerant anaerobe, E. Mesophile, F. Thermophiles 1.The bacteria under study thrives at the alveolar ducts in the lungs causing respiratory disease. 2.In the experiment, the agar plate containing an axenic culture was originally incubated inside a candle jar for one day and then transferred to an oxygen-rich incubator for another day. Findings: the microbial growth persisted and stayed the same regardless of the specific type of incubation employed. 3.A microorganism that can survive pickling and refrigeration was discovered when a tightly-sealed jar of pickles grew several colonies despite following the correct recipe, tight closure seal, and proper refrigeration. 4.The spoiled bottle of wine that was stored at standard room temperature…

Archae are the source of many enzymes used for biocatalysis in diverse industries such as food and feed, pharmaceuticals, detergent, and beverage industries. These enzymes have unique structural and functional properties that enable use under extreme conditions. Use: https://biolres.biomedcentral.com/articles/10.1186/s40659-018-0186-3 for supplemental info What are three classes of extremophiles and their unique growth characteristics? Based on these characteristics, where are they typically found? The functional properties are linked to protein structural characteristics that imparts unique functional properties. For alkaliphiles and thermophiles, what structural elements (or characteristics) within the enzyme structure create these unique properties? See Table 2. Briefly discuss how the unique properties of these enzymes may be beneficial to the design of bioseparation processes. To recover intracellular enzymes, the Archae need to be lysed.

Experiment #1 From Antoinette de Senna’s Master’s thesis on ‘Screening of biological control organisms for the management of phytopathogenic fungi and foodborne pathogens on produce’. Objective: To screen three LAB (Lactobacillus plantarum, Pediococcus acidilactici, and Pediococcus pentosaceus) for antimicrobial activity against the foodborne pathogens Listeria monocytogenes, Salmonella, and Escherichia coli. Methods: 1 ml of the pathogen was placed into a petri dish. Then, 15-20 ml molten tryptic soy agar (TSA) tempered to 50°C was added. When the TSA solidified, a loopful of LAB was spotted onto the agar. Plates were incubated at 35°C for 24 hours then the zone of inhibition was measured from the boarder of the bacterial colony to the perimeter of the clearing. Results: Questions: What is the independent variable? What is the dependent variable? Suggest a control for this experiment? What is the optimal temperature range for Listeria monocyogenes? Is monocyogenes a…
