Compound Microscope Parts A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. It is used to view smaller specimens such as cell structures which cannot be seen at lower levels of magnification. Essentially‚ a compound microscope consists of structural and optical components. However‚ within these two basic systems‚ there are some essential components that every microscopist should know and understand. These key microscope parts are illustrated

Starch is used in cooking for thickening foods such as sauce. In industry‚ it is used in the manufacturing of paper‚ textiles and as a mould in the manufacture of sweets such as wine gums and jelly beans. Fermentation (2)As with any food preparation‚ there are many certain aspects of the fermentation process that can change

MICROBES AND FOOD – A ‘RELATIONSHIP’ Microbes and food have always had a love-hate relationship. Food producers have learned to harness their power -- and sometimes for good use. There is no doubt that organically grown fruits and vegetables are superior in flavor. Now‚ despite arguments to the contrary made by food manufacturers‚ they may well be more nutritious for a variety of reasons. There are always studies available to prove any point‚ especially one

An important aspect of cocoa seed fermentation includes specific yeasts that cultivate ethanol and produce enzymes to degrade peptin (Schwan). This is important for setting up additional fermentation by bacteria. The main yeast present in the beginning of fermentation is Kloeckera apis which accounts for roughly seventy to ninety percent of the total yeast population (Ardhana). As previously stated‚ Kloeckera apis is a yeast or yeast-like organism with the full classification as follows:

HISTORICAL BACKGROUND In 1878 kuhne used the word enzyme (Greek: in yeast) to indicate the catalysis taking place in biological systems. Isolation of enzyme system from cell free extract of yeast was achieved in 1883 by Buchner. He named the active principle as Zymase (later found to contain a mixture of enzymes)‚ which could convert sugar to alcohol. In 1926 James Sunner first achieved

nature of enzyme actions using live yeast cells as our source of sucrose. The enzyme will then break the sucrose into one molecule of glucose and fructose. Because sucrose is a large molecule that cannot enter most cells‚ yeast will produce sucrase and secrete it into cell membranes. The sucrose will be hydrolyzed into small six-carbon monosaccharide’s which can enter into the cell membranes. The sucrose can be obtained from a 0.5 percent solution of “dry baker’s yeast in water”. In parts A and B‚
