of fungi‚ including food processing‚ drug production and bio-control agents‚ to name a few. Yeast are used to ferment sugar into carbon dioxide and alcohol. Cereal grains are fermented to produce beer‚ while wine and hard cider is fermented from grapes and apples respectively. Sake is produced by fermenting rice‚ using Aspergillus oryzae and then an additional fermentation step utilizing bacteria and yeasts. Bread is produced by fermenting the sugar to produce carbon dioxide‚ which rises the bread

ferment some foods. Ascomycota fungi are the yeasts used in baking‚ brewing‚ and wine fermentation‚ they are important in cell biology‚ genetics‚ and producing penicillin. Ascomycota are characterized by its sac like structure the ascus‚ which contains ascospores where sexual reproduction takes place outside the structure. Asexual reproduction is conidia chains that break apart and float in the air or from budding. They are either single celled as yeast or filamentous as hyphae. Ascomycota play a

fermentation of the apple and carrot juices‚ and compare their rates to each other. Introduction: Procedure: A 5.00 ml of apple juice was taken in a clean 150 ml conical flask and diluted with 50 ml of distal water. Then‚ 2.00 grams of Baker’s yeast and 5.00 ml of solution of Pasteur’s salts were added to the above conical flask. The content of flask was shacked well and maintained the temperature of the reaction mixture between 35-40 ̊ c by using hot water path. After that‚ 10 drops of the reaction

To begin‚ I had to find out how mold happens. Mold happens when bread is left out in moist areas. Mold grows because it seeks moisture warmth and food. Mold forms because in dust there are tiny micro-organisms and fungi along with it. The type of fungi found in air is called a spore‚ and it does the same thing as the dandelion seeds when you blow them in the air. A spore will float around until it lands on something and if that something is food‚ that spore will germinate and grow into a fungus

running head: UNIT 10. ASSIGNMENT Environmental Microbiology With so much advertising for various antibacterial products‚ many people have gotten the impression that all bacteria are harmful and that maybe the Earth would be better off if all bacteria were eliminated. What would life be like in a bacteria-free world? Bacteria help decay materials and put vitamins and minerals‚ and gases into the atmosphere. Without them the world would be able to produce little food. Bacteria are woven into
