Microorganisms have been used for preparing food products such as cheese‚ bread‚ yogurt‚ etc‚ for a long period of time without even knowing that the process involves fermentation of the starting material (Pai‚ 2003). Fermentation is the process of utilizing nutrients anaerobically (D ’Souza & Killedar‚ 2006). Yogurt is a product of fermentation brought by adding Streptococcus thermophilus and Lactobacillus bulgaricus to ferment the milk and turn it into a thickened acidic food ( Lee & Lucey‚ 2010)

different conditions will cause the yeast to be most active during fermentation. We put a different mixture in each bottle along with 1/3 cup of water. My hypothesis was that when yeast is mixed with more than sugar or items that contain a lot of sugar‚ the fermentation of the yeast is affected. The experimental results supported my hypothesis by showing that when yeast and sugar was mixed with items such as‚ vinegar and salt‚ the fermentation was affected.

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

up to humans to embellish‚ improve‚ or totally obliterate what nature has provided‚ to which anyone with extensive wine tasting experience can attest. There are five basic components or steps to making wine: harvesting‚ crushing and pressing‚ fermentation‚ clarification‚ and aging and bottling. Undoubtedly‚ one can find endless deviations and variations along the way. In fact‚ it is the variants and little deviations at any point in the process that make life interesting. They also make each wine

life. In the words of Trefil (1992‚ p.93) “hooking and unhooking the last phosphate is what keeps the whole world operating”. 2. Fermentation is a process used by the human body to catabolize (break down) sugar (glucose) to create energy in the form of Adenosine Triphosphate (ATP). A. The process that does not involve oxygen which is known as anaerobic fermentation‚ which is not unlike the more efficient aerobic respiration. Only 2 ATPs are released during as compared to the aerobic

varying trials of the one temperature may have had varying temperatures‚ creating error for obvious reasons. The validity of the experiment could also have been improved if the fermentation was recorded over a longer period of time‚ further research suggests that a minimum time of 45 minutes is ideal when waiting for yeast fermentation. A longer period of time may have allowed for the water in the beaker to heat or cool the flasks more effectively and create a more accurate response‚ especially as it was
