The chemistry of the bacterial cell is brought into focus as students examine bacteria and their interaction with the environment. Enzyme catalysed chemical reactions in bacteria provide energy for the bacteria as they change food into secreted waste products. In some cases, bacterial waste products can be the cause of disease symptoms, and in other cases they may create foods and nutrients for people. Thus, sometimes bacteria can be our friends and at other times our foes. For a long time, biotechnology has utilised friendly bacteria in the production of foods such as cheese, sauerkraut, coffee, sour cream, vinegar, sausage, and yoghurt. Other bacteria cause cholera, typhus, leprosy, tuberculosis, and anthrax. In this lab, students will examine both the risks and benefits of bacteria to better understand their roles in disease and in food production. Discover the Cause of Disease. In the 1700s, bacterial diseases were still a deadly mystery. Bacteria were sometimes found in diseased humans and animals - but did the bacteria cause the disease or did the bacteria merely follow a disease caused by another unknown agent? To know the cause is the first step towards cure or prevention. Join Robert Koch, Louis Pasteur, and the founders of modern microbiology in a thrilling search to find the bacterial culprit behind a new disease. The new disease examined in this lab is 'yoghurtness' - an affliction of 'healthy' milk that causes it to become acidic and thick. What is the cause of yoghurtness? Can you use Koch's postulates, the standard of proof in the identification of microbial disease agents, to identify the guilty microbe in this enquiry based activity? Students will use microscopes, agar plates, and their powers of observation to identify the bacteria used to produce yoghurt and to provide proof for their hypothesised identification. Use this kit to examine metabolism, cellular chemistry, and the role of bacteria in both disease and food microbiology. This kit supports 32 students. Key Kit Features: ¥ Isolate yoghurt causing bacteria ¥ Culture bacteria from yoghurt ¥ Follow Koch's postulates ¥ Learn laboratory microbiology skills ¥ Study food microbiology and bacteria metabolism ¥ Complete in 3 x 45 minute lessons NB: You will also require incubation oven, microscope, pH strips, yoghurt, milk, toothpicks.
