Laboratory Exercise #5 Identification of Fungi Fungi‚ like bacteria‚ may be useful in industry but also problematic. Many produce important products including foods‚ chemicals‚ enzymes and pharmaceuticals such as antibiotics and hormones. Molds‚ however‚ in particular‚ are also common contaminants in industry. It is important to be able to recognize and identify them‚ therefore‚ in the laboratory. In today’s laboratory session you will examine some common molds and attempt to identify them.

It was a hot summer day in Paris July 6th‚ 1885. Louis Pasteur had just finished vaccinating the 9-year old Joseph Meister. This was a new beginning‚ a new era for Pasteur and the rest of the world. He had created a vaccine for the deadliest disease of all time: rabies. He was very proud of his accomplishment‚ and looked back on how much progress he had made in the field of medical sciences. Many summers before‚ in the year 1882 in Paris‚ France‚ Pasteur had yet to create a furrow between his brows

Background: Bacteria is a prokaryotic cell that reproduces using the process of binary fission. Binary fission is “The process in which a parent cell splits into two daughter cells of approximately equal size”(northwestern.edu). The reproduction of bacteria can be stopped using antimicrobials. Antimicrobials were created and are used “to destroy disease-causing microbes”(cdc.gov). That means that antimicrobials fight and destroy organism such as bacteria. We use antimicrobials to clean are house

1. Pathogen. For an infection to occur‚ a microbe capable of causing disease must be present. 2. Reservoir. Reservoir is a French word that means “storehouse.” Here‚ we are using it to mean a place where microbes can grow and multiply. Possible reservoirs for microbes include the bodies of people and animals‚ bodies of water‚ and food. 3. Portal of exit. Portal comes from the Latin word for “gate.” For an infection to occur‚ the microbe must have a way of leaving the reservoir‚ or a portal of exit

I tested ten surfaces and let the petri dishes grow for five days. Over the five days I counted the spores each day and took pictures every other day. It is amazing how things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one
