this unknown sample. First‚ the plate was analyzed for its hemolysis characteristics. Afterwards‚ a Gram stain was performed from a sample of the agar plate and the slide was viewed under the microscope. Once‚ the microscopic visual was captured‚ a catalase test followed. Next‚ for further data‚ MSA results were recorded‚ along with antibiotic observations of demo plates. Lastly‚ with the information gathered‚ it was identified that the unknown sample was Streptococcus salivarius. Introduction:

below 40 but above 20‚ then the liver will show bubbles. If the temperature is raised higher than the optimum temperature‚ then an extreme decline in enzyme activity would occur following by the quick denaturing of the enzyme‚ rendering it is permanently useless. Also about 37°C is body temperature. The liver that was at 25°C had a huge amount of bubbles (a 4 on the scale) and the 0°C still had some bubbles but not as much (a 2 on the scale). The boiled liver had no bubbles. My hypothesis was

Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed

Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase is an enzyme found in food such as potato and liver. It

The decision of a laparoscopic liver surgery or open liver surgery is based on the location and size of the tumor. Laparoscopic (minimally invasive) liver resection can be performed through three of four small keyhole-sized incisions in the abdomen to remove the tumor whether they are benign or malignant. The patient experiences lesser pain and scarring as compared to the traditional open liver resection and can be discharged earlier‚ approximately in two to three days after the procedure. Standard
