Physics Of Microbiology For Scientists - 954 Words

It is common in the field of microbiology for scientist to need to quantify bacteria. A way to do this is via the production of CO2. Carbon dioxide can be produced as a byproduct of cells performing regular respiration and decomposition activities. For microbes to live and grow successfully they need an adequate source of carbon. The microbes can either produce this source themselves making them autotrophic or receive the carbon from and outside source making them heterotrophic. Without a proper carbon source microbes like bacteria would not be able to function properly and produce several vital components for life including lipids, DNA, sugar, and proteins. All carbon sources are not created equally, not all of them can be used in the same chemical pathway. Glycolysis requires the use of glucose whereas the citric acid cycle can use citrate directly. Lactose is an extremely complex sugar and must be broken down a number of times before it is usable in the process of glycolysi s. Succinate and acetate just like citrate can enter directly in to the citric acid cycle or it can also be converted into Acetyl-CoA. Due to the nature of these cycles and how the carbon gets broken down some carbon sources are naturally better than others. Glucose is the best theoretical source with the ability to produce around four CO2 molecules. The second best would be lactose that could produce the same amount of carbon dioxide but at a slower rate. This is followed by citrate whichShow MoreRelatedThe Occupational Characteristics of Microbiology761 Words   |  3 Pagesmath credits and 8 physics credits.

The scientist, however, strongly believes that a weapon of this magnitude should remain nonexistent. Should he or she continue with this research even though it could be used to create a weapon of mass destruction? The scientist absolutely should.

Through his patience and diligence Pasteur was able to make several advances in chemistry, microbiology, immunizations and preservations. In 1857 he developed the Germ Theory of fermentation and putrefaction, these theories assisted in the surgical revolution of antiseptics developed by Joseph Lister.

After two tries to enter, Louis was now in École Normale Supà ©rieure which is like graduate school in today’s world (Tames n. pag.). He then received a Bachelor of Science license and began teaching physics at the Collà ¨ge de Tournon. Louis did not stay t here long as he joined Antoine Jà ¨rome Balard at the École Normale Supà ©rieure where he began his research and wrote his theses.

In 1838, Louis went to college where he studied to become a science teacher. He earned degrees in mathematics, physics, and chemistry and became a chemistry professor at the University of Strasbourg. While he was teaching at the university, he met and fell in love with Marie Laurent and they married in the same year on May 29, 1849.
