Morales‚ Marinel M. Dr. Annie Cu Gallardo BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some

Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

Optimal Growth Conditions and Generation Time for E. coli Introduction The goals of these exercises were to determine the optimal growing condition and the generation time of E. coli. Materials and Methods Please refer to the lab manual for a complete list of materials. To determine the optimal growth condition for E. coli‚ we had to test the environmental factors that could affect the growth. We tested the relative growth of E. coli in the presence and in the absence of oxygen. The results

Phelps‚ Biology 205 MW 2:10pm. Unknown Organism Paper The unknown organism tested in the Mesa lab was collected from in between the toes of my puppy‚ Riley. The original culture grown consisted of dozens of visibly different organisms of varying colony colors and growth patterns. I chose to test a smaller‚ red colony for my experiments. Based on its gram reaction and oxygen requirements‚ the following tests were performed to reach my presumptive ID: Test Performed Result Gram Stain +

-Unknown Mixtures Lab- Purpose: The aim of this experiment was to find out the two substances of the unknown mixture from salt‚ sugar‚ dirt‚ and baking soda by looking at its properties. Hypothesis: Find the unknown substance by testing it out by heating it‚ pouring water‚ vinegar‚ and observing it . Procedure: 1) Materials- * 100ml of water * Vinegar * Bunsen Burner * 2 beakers * 1 spatula 2) First‚ do steps (3-6)to find out the properties of salt‚ sugar

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

Pure Culture Techniques In this first lab‚ you will be learning some very fundamental and important techniques. As is the case with most things‚ shorts cuts usually get you in trouble. This is especially true in Microbiology. The techniques you will be learning tonight‚ if mastered correctly‚ will make your life and learning experience in Microbiology much easier‚ if you don’t pay attention and practice these techniques incorrectly‚ well then……? Today you will be learning the following techniques:

Osmosis 4/13/13 MLT1 Lab 9 Performed at Home Microbial Growth There are three types of environments in which cells are located which include isotonic‚ hypotonic and hypertonic. In an isotonic environment‚ the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell‚ the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of
