Microbial analysis of soil‚ of top layer from selected sites of Area near Dahisar River Saika N. Esani University of Mumbai (Email – saikae@ymail.com) Abstract: soil samples were collected fortnightly from area near Dahisar River‚ A river in suburb of Mumbai. laboratory analysis started from July 2010 to September 2010. Total bacterial and fungal count were estimated by standard spread plate isolation. Isolated bacteria were subject to colony characterization and were estimated by their

equal amount of hydrogen peroxide . Dependent variable The inflation of the balloon being measured by various yeast concentrates. 3. Name three variables that you controlled between conditions in this experiment. 1. The same amount of time was given to each reaction. 2. A balloon was used to measure all three experiments. 3. All three were given the same amount of hydrogen peroxide. 4. Using the data you recorded in the lab manual‚ calculate the RATE of the reaction catalyzed by catalase. To calculate

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Desizing Desizing is done in order to remove the size from the warp yarns of the woven fabrics.The sizing material present on the warp yarns can act as a resist towards dyes and chemicals in textile wet processing. It must‚ therefore‚ be removed before any subsequent wet processing of the fabric. Object: 1. To eliminate the water repellent nature of sized cloth. 2. To increase the absorbency. 3. To reduce the consumption

Ribosomes b. Peroxisome c. Microfilaments d. Centrioles e. Nucleoli Answer: d The ribosomes are the site of protein synthesis. Peroxisomes contain enzymes for detoxification. One of the enzymes within peroxisomes is catalase. Catalase is involved in the breakdown of hydrogen peroxide. Microfilaments are made of actin. They form the cells cytoskeleton. Centrioles are composed of microtubules. Centrioles are at the base of cilia and flagella. They are also involved with cell division. Ribosomes are

Biology 101 Exercise 2 Write Up A local chicken farmer heard a lot about the bird flu so he freely decided to apply monthly physicals for his chickens. An observation made is that chickens have a body temperature of 104 degrees Fahrenheit. That worries the farmer so he decides to conduct an experiment to try to figure it out. The question is “Do the chickens have a fever?” According to the information the cells are composed of hundreds types of enzymes and each one has a specific role in

1. What are prions and satellite viruses? Prions are groups of noncellular infectious agents‚ but are not viruses. In fact‚ they are naked protein molecules that lack nucleic acid. The diseases associated with prions are called Transmissible Spongiform Encephalopathies or TSEs. These diseases spread from host to host through direct contact or through the contamination of food. Satellite viruses are viruses that depend on other viruses to replicate. An example of this is the adeno-associated virus

Purpose: The purpose of this lab was to observe and understand the effects of changes in temperature‚ pH‚ enzyme concentration‚ and substrate concentration on the reaction rate of an enzyme-catalyzed reaction. Another purpose of the lab was to explain how environmental factors affect the rate of enzyme-catalyzed reactions. Hypothesis: I believe that if there is an increase in enzyme concentration‚ an increase in temperature‚ or an increase in pH‚ then the intensity of the reaction will

Discussion After doing a series of different biochemical tests for the isolated organisim from the sputum sample‚ it was concluded that the unknown Gram positive organism was Streptococcus pyogenes. The sputum sample was first inoculated in the agar plates MAC‚ SBAP‚ CHOC and also a direct gram stain of the sample was performed. After a day of incubation‚ the MAC agar gave a negative result‚ therefore it is not a Gram-negative bacteria and non-lactose fermenting. The SBAP and CHOC showed growth
