February 24‚ 2012 Identifying Salmonella choleraesuis using Several Microbiology Lab Techniques The purpose of this study was to determine what an unknown bacteria was using several different microbiology lab techniques including an API test‚ an oxidase test‚ a gram stain‚ a hanging drop slide‚ and morphology identification. The unknown bacterium‚ which was contaminated with Serratia marcescens‚ was isolated by streaking the bacteria solution to single colonies. The isolated unknown white bacteria

bacteria‚ while firmicutes are the bacteria that make it difficult to lose weight and are actually making you fatter. The Solution Thomas Newman explains that foods containing polyphenols‚ which are rich in antioxidant properties‚ will eliminate firmicutes and increase the number of bacteroidetes‚ the good bacteria. Polyphenol-rich foods also keep blood sugar low and stop the creation of new fat cells. In the French Wine for a Flat Belly guide‚ Thomas explains this idea in detail‚ and also provides

Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were oxidase‚ catalase‚ lactose and sucrose fermentation‚ Kugler/iron agar‚ nitrate reduction‚ gelatin hydrolysis‚ starch hydrolysis‚ manitol salt‚ MR-VP‚ citrate‚ bile esculin‚ indole‚ urease‚ DNase‚ and coagulase.

Enzyme Immobilization Methods Covalent Binding: Covalent binding is a conventional method for immobilization; it can be achieved by direct attachment with the enzyme and the material through the covalent linkage [37]. The covalent linkage is strong and stable and the support material of enzymes includes polyacrylamide‚ porous glass‚ agarose and porous silica [38]. Covalent method of immobilization is mainly used when a reaction process does not require enzyme in the product‚ this is the criteria

Guava is a small tropical tree that grows up to 35 feet tall; it is widely grown for its fruit in tropics. It is a member of the Myrtaceae family‚ with about 133 genera and more than 3‚800 species. The leaves and bark of P. guajava tree have a long history of medicinal uses that are still employed today (Nwinyi et al.‚ 2008). In the view of the immense medicinal importance of P. guajava plant evidenced in the various studies mentioned above and also corroborated in a recent review article by Kamath

I had # 8 organism‚ Bacillus subtilis. Bacillus subtilis is a Gram-positive bacteria‚ rod-shaped and catalase positive. In order to figure out what is my unknown organism for this assignment‚ I had to perform series of tests. First was the glucose‚ lactose‚ and sucrose test. Through these three tests‚ I was able to detect the ability of the microorganism to ferment a specific carbohydrate. Fermentation reactions are observed by the color change in pH. In class‚ we used phenol red as the pH indicator

The mango is a fleshy stone fruit belonging to the genus Mangifera‚ consisting of numerous tropical fruiting trees in the flowering plant family Anacardiaceae. The mango is native to South Asia‚ from where it has been distributed worldwide to become one of the most cultivated fruits in the tropics. While other Mangifera species (e.g. horse mango‚ M. foetida) are also grown on a more localized basis‚ Mangifera indica – the ’common mango’ or ’Indian mango’ – is the only mango tree commonly cultivated

radicals are damaging substances generated in the body that cause undesirable changes and are involved in the aging process and some diseases. Some animal studies have found that an antioxidant found in apples (polyphenols) might extend lifespans. Tests on fruit flies found that polyphenols also help them to preserve their ability to walk‚ climb and move about. Another study found that adult females who regularly ate apples had a 13% to 22% lower risk of developing heart disease. Fuji apple
