The catalase test is used to differentiate staphylococci (catalase-positive) from streptococci (catalase-negative). The enzyme‚ catalase‚ protects the bacteria from the toxic by-products of oxygen metabolism. This enzyme is produced by bacteria that respires using oxygen. The catalase-positive bacteria include strict aerobes. Catalase-negative bacteria may be anaerobes‚ or they may be facultative anaerobes do not respire using oxygen as a terminal electron acceptor. The test reaction is very fast

Q.1: what did Churchill mean in May 1945 by the term “Iron Curtain”? A.1: When Churchill stated “An Iron Curtain is being drawn upon their front.” He means that during 1945 when the war was over‚ he was talking about an imaginary line drawn between communism in the East and the democratic governments in the West.

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

lab experiment six different test were conducted. Each test consists of chemicals to be tested using 3 to 10 drops of the additive in order to observe a change. With any experiment you compose a hypothesis; where you make an educated guess. The hypothesis will primarily be‚ which base chemical will produce the greatest change based on the additive. Experiment 6.1 (Starch) when adding the three drops of Iodine to each tube observe the color change. When performing this test the chemical with the larger

3.1 Ex-vivo Evaluation of the Mucoadhesiveness of Synbiotics Mucoadhesive properties prolong the retention time of the bead’s dose in the targeted site the colon [23]‚ [50]. Since the dose is intended to colonic release‚ mucoadhesion parameters play a key role in the efficiency of the form. The beads remain longer in contact with colonic mucosa when they have more mucoadhesive property. As a result the probiotics will have enough time to get released from beads and colonize the colon [37]‚ [51]

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
