Next, complete the microbial identification experiments listed below. Then, write a lab report discussing the results of these experiments. You will need the Staphylococcus epidermidis culture for the next task, so do not discard it.
Your lab report should be written in complete sentences and in paragraph form. Your report should include the following sections: The information required for each section is outlined below.
Write a lab report about the Aseptic Technique and Culturing Microbes LabPaq experiment and the microbial identification experiments in which you do the following: Discuss the importance of using proper aseptic technique when working with microorganisms. Discuss the importance of generating a pure culture.
The discussions from parts A1 and A1a belong in the introduction of the lab report. Explain how the following experiments were performed: The explanations from parts A2a—d belong in the materials and methods section of the lab report.
Your explanations should focus on organisms used, media used, the time of incubation, and any reagents that were added.
The explanations from part A3a—c belong in the results section of the lab report. The descriptions from part A4a—c belong in the discussion section of the lab report. You will only discuss the biochemical characteristics that you observed.
Aseptic technique, designed to provide a barrier between the microrganisms in the environment and the sterile cell culture, depends upon a set of procedures to reduce the probability of contamination from these sources. Lab Exercise 3: Media, incubation, and aseptic technique Know the laboratory equipment and culture media needed to develop and maintain pure cultures 6. Carry out aseptic technique for the removal and transfer of microorganisms for culturing. 7. Correctly sterilize and flame transfer instruments and tubes. Cell culture is also a key technique for cellular agriculture, which aims to provide both new products and new ways of producing existing agricultural products like milk, (cultured) meat, fragrances, and rhino horn from cells and microorganisms.
For example, Escherichia coli was not tested for salt tolerance, so a discussion of the salt tolerance of Escherichia coli would not be included. Acknowledge sources, using in-text citations and references, for content that is quoted, paraphrased, or summarized.
When using sources to support ideas and elements in a paper or project, the submission MUST include in-text citations with a corresponding reference list for any direct quotes or paraphrasing.This section provides useful hints for culturing animal cells (i.e., cells derived from higher eukaryotes such as mammals, birds, and insects).
It covers different types of animal cell cultures, considerations for cell culture, and cell culture protocols. May 31, · If using micropipettors to transfer sterile solutions, it is strongly recommended that aliquots of stock solutions (media, buffer, water) be made using aseptic technique with serological pipettes.
It is common to maintain working stock solutions in 15 ml or 50 ml sterile conical tubes.
Aseptic technique, designed to provide a barrier between the microrganisms in the environment and the sterile cell culture, depends upon a set of procedures to reduce the probability of contamination from these sources. colonies on this second plate will indicate a pure culture.
Most microbiologists repeat , , ) The use of the streak plate technique requires knowledge of rules of aseptic technique. Whenever working with a culture, the microbiologist must proceed with care to ensure that the culture is not contaminated during the manipulations.
Microbiology Theory: Media Preparation. Categories; Defined media are media composed of pure ingredients in carefully measured concentrations dissolved in double distilled water i.e., the exact chemical composition of the medium is known.
Typically, they contain a simple sugar as the carbon and energy source, an inorganic nitrogen source.
A. Write a lab report about the Aseptic Technique and Culturing Microbes LabPaq experiment and the microbial identification experiments in which you do the following: 1. Discuss the importance of using proper aseptic technique .
