a. The bacteria that causes botulism are found in soil‚ water‚ animal guts and dung. When the spores exposed to low oxygen and certain temperature‚ they produce botulinum toxin‚ able to germinate‚ metabolize‚ food sources through an aerobic respiration to produce toxin. The toxin blocks the release of acetylcholine from motor nerve endings causing paralysis symptoms. The botulism either food born‚ eating contaminated home-canned foods where the fermentation takes place. or through abrasion in the

ANALYSIS OF BACTERIA GROWTH Abstract Bacteria can be found everywhere on the earth. Bacteria are single-celled organisms that lack a nucleus‚ mitochondria‚ and chloroplasts and are surrounded by a cell wall containing a peptidoglycan layer. They are defined by their small size and wide range of shapes. In this experiment we separated organisms in a mixed culture to study the colony morphology and physical characteristics and determine which organism was present in higher numbers‚ as determined

Oxygen Requirements of Bacteria BACKGROUND The GasPak system is useful for culturing anaerobic bacteria on standard microbiological media because the GasPak generates carbon dioxide and hydrogen. The hydrogen will combine with oxygen present in an anaerobic jar to produce water. This system can reproducibly attain oxygen levels in the parts per million range if used correctly. This is the best method for determining the oxygen requirements of unknown organisms. A candle jar is useful

Modern Day Example of Natural Selection – Antibiotic Resistant Bacteria Read pg 112 -113 & 275 – 277 of you text book. Use this information plus information from secondary sources to answer the following questions so you will have a case study on antibiotic resistant bacteria. In this case study you will need to show how an environmental change can lead to a change in a species. Note: this will also cover content in the Search for Better Health topic. 1. Outline the purpose of anti-biotics

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

between a gram positive bacteria and gram negative bacteria is the differences in cell wall composition. Prokaryotes known as eubacteria have three basic forms: rods‚ cocci and spiral. The bacterial cell wall is the single most important contributor to cell shape. In addition to shape of cell wall‚ presence or absence of flagellum‚ and if present‚ positions of flagellum‚ the eubacteria can be classified according to Gram Stain. First and foremost‚ gram positive bacteria are by and large dark

Why it’s important to have self respect.Because If I don’t have respect for myself I won’t be able to respect others . People won’t be able to respect me.The little kids that I’m around will think that hitting myself and getting into trouble (doing drugs ‚robbing banks ‚E.t.c) and smoking and drinking is cool.If I don’t respect myself it might affect the future generation.If I don’t respect myself it could affect someone very important to me.For example‚ if I do drugs it will one affect my grades

Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several
