BIO374H5 Study Guide - Midterm Guide: Pichia Pastoris, Gram Staining, Calcium Chloride
Document Summary
Microbes (microorganisms) small, need to use a microscope are tiny organisms that are too small to be seen individually by the naked eye and must be viewed with the help of a microscope: ex. Bacteria can survive in harsh environments (extreme high or extreme low temperature), also in deep sea: ex. polar ice caps, deserts, boiling hot springs and under extraordinarily high pressure in deep-sea vents miles under the ocean"s surface. Humans have long used microbes in "traditional biotechnology" and microbes are central to recombinant dna technology. Bacteria is useful as vectors and other stuff (like making wine) Even though there are different types of bacteria, there is less than 1% that have been identified (good because we can still study them in the future) Prokaryotes (know terms below) are single celled microorganisms which include the domains. Bacteria and archaea: can survive in salty environments (halophiles, can survive in hot environments (thermophiles)
