GRIMONT Introduction The genus Enterobacter was first proposed by Hormaeche and Edwards (1960a). However‚ the history of some species now placed in the genus Enterobacter can be traced‚ albeit with some confusion‚ to the end of the 19th century. “Bacillus lactis aerogenes” was isolated by Escherich (1885) from milk

Genetically Modified Microorganisms John A. Doe Strayer University- Morrow Campus Genetically Modified Microorganisms Genetically modified microorganisms or also known as genetically modified organisms are organisms whose genome has been engineered in the laboratory in order to favor the expression of desired physiological traits or the production of desired biological products. Otherwise known for as in lames terms as an organism whose genetic material has been modified or altered

Life beyond Earth does exist. The life that exists beyond Earth is only simple microbial life. In order for complex life to exist many specific events would have had to happen which is highly unlikely. Spacecrafts have found regions of other planets that appear to be able to sustain simple life. Simple life forms have been found on Earth in extreme conditions never thought possible. On someplace other than Earth simple life forms do exist. If complex life were to occur on places other than

c) In what ways did the understanding of the treatment of disease change in the years 1860-1945? The treatment of disease changed dramatically in the years 1860-1845 due to the changes of how people understand it‚ how each discovery such as Pasteur’s opens new doors‚ leading to other discoveries such Koch’s identification of germs‚ the magic bullet and discovery of penicillin. this has help society to understand the causes of disease‚ and the ways to tackle it. These discoveries began in

FIELD TRIP TO SIRIM SDN BHD By definition‚ Biotechnology is the exploitation of biological processes for industrial and other purposes. The theoretical aspect of the overall learning of the course has been overwhelming in the sense that human life and environment has been positively advanced with the advent of biotechnology. To further have a hands on the practical applications of biotechnology was a motivational factor that lead to a visit to Sirim Berhad‚ a Malaysian government owned company that

Virus vs. Bacteria Similarities – Virus vs. Harmful Bacteria Virus and Bacteria are similar. But yet they are different. Viruses and bacteria can make copies of themselves once they are inside a living organism (“J. L.”). They are both harmful bacteria and viruses. These bacteria and viruses can be helpful to the body. All diseases that people get are from virus and bacteria( Microbe Magic). Bacteria and virus are both microscopic organisms that have the same brain structure that why they are called

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

How do bacteria affect human lives? Bacteria interact and are a constant in our day to day lives‚ perhaps more than suspected. Bacteria are often thought of as bad‚ however this is untrue‚ there is also many types of ‘good’ bacteria. ‘Good’ bacteria can benefit us by simply helping our digestive system work and helping us in the process of fermentation. Bacteria are extremely helpful in the production of many things such as fuel and medicine. But bacteria directly affect our production of

Penicillin V is a first-generation penicillin used to treat infections generally caused by gram-positive bacteria. Penicillin V consists of 16 carbons‚ 18 hydrogens‚ two nitrogen‚ five oxygens and a sulfur atom. The beta-lactam group is the ring composed of two nitrogen‚ a sulfur atom‚ and an oxygen double-bound to a carbon. Penicillin works by bursting a bacteria’s cell wall; this is done by inhibiting the proteins that link peptidoglycans together in the cell wall‚ which prevents the bacteria from

1. Salmonella enteritidis is a gram-negative bacterium that causes food-borne illnesses‚ and is the most commonly known serotype of Salmonella. It is a constant problem because of the misuse of antimicrobials in farms‚ disease treatment‚ growth promotion in domestic livestock‚ and the increasing problem of antimicrobial resistance. Current research is being conducted with bacteriophages because they have been identified as a prospective alternative bio-control method to control Salmonella contamination
