Pillay‚ Esmerelda (209504371) School of Biochemistry‚ Genetics and Microbiology Department of Microbiology University of Kwa-zulu Natal 25 October 2010 ABSTRACT Different types of bacteria in various forms are found all around us‚ and it is a microbiologist’s job to be able to identify these bacteria. Using various staining techniques and physiological tests‚ an isolated bacterium can be identified. In this experiment‚ a single bacterial colony was isolated form Mycorrhizal spores‚ and further

Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because they are small and because they infect cells. While most bacterial are unicellular they can also exist in colonial or multicellular forms. In this laboratory exercise you will examine the ubiquity and diversity of various microbes that are present in the environment or inhabit the human body. Most bacteria that inhabit the body are

Bacteria and Archaea Bacteria and Archaea All single-celled organisms in the Bacteria and Archaea domains are referred to as prokaryotes. Prokaryotes are organisms whose genetic material is not contained within a nuclear envelop. These cells are profoundly important to the environment‚ medicine‚ and industry. (Postlethwait & Hopson‚ 2010‚ p. 196) Bacteria and Archaea are similar in shape‚ size‚ and appearance. They are both found occurring as rods (bacilli)‚ spheres (cocci)

importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling of raw materials. Industry applications of microbiology: waste management‚ food industry‚ mining‚ medicine‚ research and

Isolation of Bacteria in our Physical Environment Introduction: The purpose of the lab is to apply what has been learned so far in Microbiology‚ and use it to collect and examine microbial species from the physical environment. The physical environment around the lab will be utilized to find out the variety of different microbial species growing in and around the lab. This investigation will help in preparation for the individual projects that will be done at the end of the semester. Materials

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

Yannelly De Leon General Intent vs. Specific Intent “Intent: A determination to perform a particular act or to act in a particular manner for a specific reason; an aim or design; a resolution to use a certain means to reach an end.” [1] The difference between General Intent vs. Specific Intent is when the defendant commits a crime with a specific end in mind and general intent is when a defendant commits a crime with no specific result in mind. General intent crime includes but is not limited

Penicillin Changed the World Imagine life without antibiotics‚ people dying of a whooping cough‚ a minor wound or even a simple infection. Until the accidental discovery of penicillin by Alexander Flemming‚ life was like this. The positive effects for the discovery of penicillin were the many medical advancements made both therapeutically and medicinally. Economically‚ people were living longer lives and populations were growing more rapidly. Socially‚ people were able to interact without risking
