Serial Dilution Activity Many applications require the determination of microbial numbers. Those applications can be either clinical or in a research setting. Clinical applications include determination of antibiotic efficacy and as well as therapy. Research applications include determination of the effectiveness of antimicrobial chemicals‚ radiation‚ etc. The viable count is most common or standard method used to quantitate bacteria. With this method only microbes that are alive and able to reproduce

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

satellite technology. Satellite television is a system of supplying television programming using broadcast signals relayed from communication satellites. The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter (LNB). A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes‚ or a built-in television tuner.
