Saphire‚ 2009) Ebola-Zaire and Ebola-Sudan are the most lethal with mortality rates upwards of 90% and 61% respectively. (CDC.gov) Ebola virus is classified as a Class A bioterrorism agent and one that must be handled bio- safety level 4 labs. Research of Ebola virus requires trained professionals and facilities with rigorous levels of control to access. (CDC.gov) Like other viruses‚ the survival and spread of Ebola is dependent upon the host organism. At this time‚ the natural reservoir

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations

BIO 225 – Exam 2 Review Sheet Chapter 9 1. Know the anatomy of the structures that make up the prokaryotic cell. Know their functions. Know any clinical significance each structure might have and if it is a target for antibiotics. (On separate sheet) 2. Know the differences between Gram positive and Gram negative cell walls. * Gram positive cell wall * In addition to many layers of peptidoglycan‚ the cell wall of Gram-positive bacterials cells also contain: * Teichoic

I did not learn my communicating skills until I took my microbiology class. I had to do a project on sexual transmitted diseases (STD) and it required meeting after class. Being shy and not confident enough‚ I didn’t want to meet my group. Dr. Nande called me one day because some of my group partners complained to him. I stood in front of him looking down nervously on what he was going to say. He read my body language and just said that I can either tell him what the problem is or I can take a zero

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

pH and Chromatography Lab Report Kevin Rivera Biology Mr. Langley 2C 10/7/13 Introduction In this lab‚ of pH and Chromatography‚ in the pH aspect of the lab we are trying to figure out the pH level of certain chemicals by writing down of known solutions to find the type of unkown solution using pH standards. In the Chromatography‚ we are trying to separate the chemicals using water and a piece of paper. Methodology Materials: Safety Goggles pH indicator & pH indicator key

Cell wall composition • :Gram negative . • Gram positive. b. Nutritional requirements : • Autotroghs:take nutrition from carbon dioxide. • Heterotrophs take the nutrition from organic carbon(carbs‚lipids‚protein) • Prototroph: take nutrition from sunlight. • Chemotrophic take nutrition from chemicals. c. Oxygen requirement
