Investigating the effect of pH on amylase activity Aim The aim of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which

Abstract In this lab‚ we tested the effects of temperature on fungal amylase and bacterial amylase (Aspergillus oryzae and Bascillus Licheniformis). We used 4 different temperatures in Celsius 0‚ 23‚ 58‚ and 89 for both fungal and amylase. For 10 minutes‚ every 2 minutes we would use 3 drops of each amylase and mix it with iodine to observe the presence of starch at each temperature. We conducted this experiment for both bacterial and fungal amylase. Results were reached based on the color of the

2. Biological Classification Classification The process of grouping living organisms into convenient categories based on simple characters is known as classification. 1. Two kingdom classification Carolus Linnaeus divided all living things into two kingdoms- Plantae and Animalia. 2. Five kingdom classification R.H. Whittaker divided all living things into five kingdoms- Monera‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The main criteria for classification included o cell structure o thallus

Introduction Food preservation has long been practiced since the olden times with processes such as heating ‚ drying‚ fermentation and refrigeration. In spite of this‚ physical methods are not enough to eliminate all microorganisms found in foods. Therefore‚ antimicrobial agents are needed to destroy these foodborne pathogens‚ so that the food will have a longer shelf-life. As technology progresses‚ improvements
