In this study‚ three general media will be used for the detection of microorganisms on the equipment‚ personnel‚ raw materials and the finished goods. These are Potato Dextrose Agar (PDA)‚ Plate Count Agar (PCA) and Violet Red Bile Agar (VRBA) under the Univar brand. The amount of each prepared medium or dehydrated medium depends on the number of samples to be tested. PDA is usually used for the presence of yeasts

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Sweet Potato Pie Eugenia Collier From up here on the fourteenth floor‚ my brother Charley looks like an insect scurrying among other insects. A deep feeling of love surges through me. Despite the distance‚ he seems to feel it‚ for he turns and scans the upper windows‚ but failing to find me‚ continues on his way. I watch him moving quickly—gingerly‚ it seems to me—down Fifth Avenue and around the corner to his shabby taxicab. In a moment he will be heading back uptown. I turn from the window

of batteries in the period 2004-8? Provide a quantitative estimate. How do you explain the fact that over that period the amount of batteries sold increased whereas the value of sales declined? From figure 20 we can see that the volume of sold batteries from 2004 (584 million batteries) to 2008 (611 million batteries) has increased by 27 million batteries. During that period of time the volume has slightly raised‚ where in 2006 was the highest volume of batteries sold 620 million batteries. Being

bless you! Cassien TWAGIRIMANA ABSTRACT The Irish potato is one of major food tuber crops grown in Rwanda. It plays a key role in food consumption‚ nutritional security and reduction of hunger. Potato plant like other tuber crops requires sufficient supply of several essential elements for proper growth and function. It is a gross feeder and exploiting greater volume of soil nutrients including nitrogen‚ phosphorous‚ potassium and water. Potato production has become very important in Rwanda in

Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

Investigating the Difference in Isotonic Point in Sweet and White Potato Research Aim: To observe whether equal sized white potato or sweet potato cores reached the isotonic point in the same concentration of sucrose solution. Introduction: Osmosis is diffusion of water from areas of high water potential to areas of low water potential. It does not require an input of energy. Plants use osmosis to transport minerals from their roots to their leaves‚ and to take in water in the soil. Because the
