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

5 drops of methyl pH red indicator was then added. During the Triple Sugar Iron Agar (TSI) test‚ A TSI slant was inoculated with bacteria at 37oC for 48 hours. Color changes and production of gas were then checked for. For the Phenyl Alanine Deaminase test‚ a phenylalanine slant was inoculated and incubated at 37oC for 48 hours. 5

Makalah Biologi Percobaan Reaksi Hidrogen Peroksida dengan Katalase Penulis: Jancolin Yani Pendahuluan Seperti yang kita tahu bahwa hydrogen peroksida yang dihasilkan oleh sel-sel didalam tubuh kita akibat metabolism sel akan terpecah menjadi gas hydrogen dan oksigen dengan adanya keberadaan enzim katalase. Zat hydrogen peroksida sangat berbahaya bagi tubuh dalam kuantitas yang banyak oleh karena itu harus dipecah dan dikeluarkan. Sebagian besar zat hydrogen peroksida

Project Title: Examination of bacterial content of sea water samples from selected sites in South East England Introduction Over the past few years coastal beaches across the UK has seen lavished with recognition for their cleanliness‚ by sections of the media and various organisarions. Majority of these beaches have been awarded the Blue flag award in recognition for meeting set criteria on various standard including cleanliness‚ water quality‚ environmental management and environmental education

Abstract: A patient arrived at the hospital recently and brought a sample their infectious disease on an agar plate. A series of tests were completed in order to identify this unknown sample. First‚ the plate was analyzed for its hemolysis characteristics. Afterwards‚ a Gram stain was performed from a sample of the agar plate and the slide was viewed under the microscope. Once‚ the microscopic visual was captured‚ a catalase test followed. Next‚ for further data‚ MSA results were recorded‚ along

Abstract Introduction An antimicrobial is a substance that kills or inhibits the growth of microorganisms such as bacteria‚ fungi‚ or protozoans (Antimicrobial). Antimicrobial drugs either kill microbes or prevent the growth of microbes. Disinfectants are antimicrobial substances used on non-living objects or outside the body. Ginger Figure 1 : Ginger (Studies Reveal Ginger Lowers Colon Cancer Risk) Ginger is commonly used around the world and has been employed in the treatment‚ cure‚ and

investigated compounds were dissolved in DMSO at 10 and 20 mg ml-1‚separately [19‚21‚25‚27‚34]. Nutrient agar was prepared‚ then sterilized in an autoclave and poured in sterile Petri plates. After cooling of nutrient ager in Petri plates‚ the studied organisms were grown on agar. After that‚ the sterili Paper discs of Whatman saturated with solution of investigated compounds were placed in the agar by working holes using a sterile crook borer. These Petri dishes were incubated for 24 h at 37oC [25]

dye‚ all of which inhibit the growth of gram-positive bacteria. As the name suggests‚ SS agar should theoretically only allow the growth of Salmonella and Shigella. In fact‚ many gram-negative bacteria cannot grow on SS agar. However‚ some enteric bacteria are able to grow on this medium‚ due to shared characteristics with Salmonella and Shigella‚ though their proliferation is limited. Both EMB and SS agars are also differential as they contain lactose‚ which causes indicator dyes in the media to

Autumn White Biology 258-05 November 26‚ 2012 Unknown #19 Enterbacteriaceae Enterobacter aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the
