Livja Koka Anaerobic Bacteria In this experiment the purpose is to seek understanding between an organism and its use of oxygen. Oxygen is a very important part of the organisms’ survival. Oxygen has a tendency to form very reactive by-products inside a cell. These by-products create havoc by reacting with protein and DNA‚ thus inactivating them. Cells that are able to live in the presence of oxygen have evolved enzymes to cope with H2O2 and O2- and thus are not inhibited by O2. Also many anaerobes

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Many bacteriocins have been characterized biochemically and genetically‚ and though there is a basic understanding of their structure–function‚ biosynthesis‚ and mode of action‚ many aspects of these compounds are still unknown. This article gives an overview of bacteriocin applications‚ and differentiates bacteriocins from antibiotics. A comparison of the synthesis‚ mode of action‚ resistance and safety of the two types of molecules is covered. Toxicity data exist for

These areas normally have an adequate supply of amino acids and vitamins (Murray et al‚ 1998; internet 1). They are aero tolerant anaerobes which mean they can tolerate oxygen but do not use it‚ (Johnson- Green‚ 2002).
