Exam 2 Study Guide Bio 202 Chapter 13 Differentiate a virus from a bacterium Describe the chemical and physical structure of both an enveloped and a nonenveloped virus. (Include a description of the envelope‚ capsid‚ and core The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus‚ especially of small ones. Each capsid

Claus (2003)‚ stated that only few bacterial laccases have been studied‚ through rapid progress in genome analysis suggests that these enzymes are also widespread in bacteria. The most well-known representative is CotA from Bacillus subtilis‚ an endospore coat protein with high thermostability (Hullo et al.‚ 2001). Other laccases have been found in Pseudomonas maltophila (Isono and Hoshino‚ 1989)‚ P.syringae (copA) (Cha and Chooksey‚ 1991)‚ Azospirillum lipoferum (Givaudan et al.‚ 1993)‚ Xanthomonas

Quantification of Microbes in Milk and Water Naomi Hall 10/20/14 BSC 381L H003 Group: Megan Baker‚ Katie Coe and Meagan Williams Abstract Coliforms are gram negative bacteria commonly found in the intestines of birds and mammals and are the most widely utilized indicators of fecal contamination. The purpose of this experiment was to test various water and milk samples for the presence of coliforms‚ specifically fecal coliforms. It was expected that fecal coliforms would be found in all

come from only a few particular drugs. Antibiotics are divided up into three major divisions‚ such as: eukaryotic molds and bacteria that form spores as well (Todar 2011). A small amount of the antibiotics we use today are formed by Bacillus‚ the endospore-forming bacteria. The others are produced by the molds‚ mostly Penicillium and Cephalosporium (Tortora 2010). The major subcategories of antibiotics are Penicillins‚ Cephalosporins‚ Macrolides‚ Fluoroquinolones‚ Sulfonamides‚ Tetracyclines‚ and
