to combat bacteria. Hypothesis If bacteria is exposed to garlic‚ then the garlic will to abolish the Escherichia coli‚ because the Escherichia coli (E. coli) is usually a weak bacteria. Procedure Have three petri dishes prepared with blood agar‚ and three test tubes with 100 milliliters of milk. Label three test tubes‚ “A‚” “B‚” and “C.” With a toothpick‚ add a small amount of the E. coli specimen to tube “B"; shake the test tube to mix throughly. For test tube “C‚” add the same amount

Taste discrimination in young and old Drosophila melanogaster Introduction The ability to discriminate taste is critical for the survival and nutrition of an organism (Sellier et al.‚ 2010‚ Gordesky-Gold et al.‚ 2008). Many animals rely on their taste organs to detect and discriminate various types of taste such as sweet or bitter (Weiss et al.‚ 2011). When these organs come in contact with a food source‚ signals are sent to taste receptor cells. The activation of certain taste receptor cells by

Biology Assessment: Influenza Structure: Viruses are non-cellular obligate intracellular parasites‚ requiring a living host cell in order to reproduce. A developed viral particle (virion) lacks the metabolic machinery of cells‚ containing just a single type of nucleic acid (DNA or RNA) encased in a protein coat or capsid. Viruses can be distinguished by their structure and by the nature of their genetic material (single or double stranded DNA or RNA). Viruses that affect humans are more difficult

TITLE Lab #4 Soil –vs- Water Microbiology INTRODUCTION There are 4 learning goals for this lab: 1. Collect samples and compile data from at least 2 sources (soil; water) of your choice. 2. Identify at least 2 Prokaryotes (bacteria) and 2 Eukaryotes (fungus) in your samples. 3. Research the importance of bacteria and fungus to Earth in a non-medical context. 4. Compile a high-quality‚ 3+ resource (excluding the lab worksheet)‚ MLA-cited in-text laboratory report using the scientific method

value of collecting‚ identifying‚ and analyzing the various microbes regularly encountered in the daily human environment becomes quite apparent .when one gains even a very basic knowledge of how diseases are acquired and spread. The purpose of this lab was to collect and observe microbes from environmental and human body samples by culturing them on the appropriate media using aseptic transfer techniques. And also regard different effect of temperature on microbial growth in Part B ‚and looking

sterilizing it with 70% ethanol. Then trypticase soy agar (TSA) was poured into six groups of 60 Petri dishes (See Appendix 1). The dishes were labeled based on the antibiotic used and were left to dry and solidify at room temperature. After an hour‚ the dishes were placed in a refrigerator at three degrees Celsius. If there was visible condensation on the agar plate‚ they were flipped to avoid the contact of heat that drove the moisture out of the agar dishes. The contents of the broth culture of E.

Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

IDENTIFYING GRAM POSITIVE COCCI As mentioned in Exercise 8‚ “Identifying Gram Negative Rods”‚ identifying bacteria is a common activity in the microbiology lab. Like the game Clue™‚ each time you gather a piece of information to solve the mystery‚ you gather some information that supports some identities and eliminates others from contention. In the lab‚ the process continues as you gather more information until only one microbe remains and all others have been eliminated as possibilities. Thus‚ identification

17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the
