Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

1. Obtain 1 gram of an impure‚ unknown substance solid. Make sure to stir the mixture before measuring the sample; record the mixture’s code in the data section. 2. Add approx. 25-50 mL of water and several boiling chips to a 125 mL Erlenmeyer flask and heat the water to a gentle boil using a hotplate. 3. On a second hotplate‚ place a 125 mL Erlenmeyer flask containing the one gram of unknown solid along with a boiling chip. 4. Using a ring clamp‚ slowly pour approx. 5-10 mL of boiling water into

Joachim Gram‚ a Danish microbiologist‚ developed a method for distinguishing bacteria by their different reaction to a stain. The process of applying Gram’s stain is as follows: the bacteria are stained with a violet dye and treated with Gram’s solution (1 part iodine‚ 2 parts potassium iodide‚ and 300 parts water). Ethyl alcohol is then applied to the medium; the bacteria will either preserve the blue color of the original dye or they will obtain a red hue. The blue colored bacteria are gram-positive;

sensitive bacteria against (EEP) with mean inhibitory diameters (22-26) mm was S. epidermidis followed by S. aerues and C. albicans (15-22) mm. Tested Gram negative bacteria have lowest inhibitory zones (7-9) mm. Results of MIC & MBC showed S. aureus with (0.1750.7mg/ml) followed by S. epidermidis & C. albicans with (0.7-1.4mg/ml). Among tested Gram negative bacteria‚ all (EEP) samples showed relatively strong inhibitory action on P. mirabilis (14mg/ml) and weak inhibitory action on P. aerugenosa

Bacillus sp.: The microorganisms in the most contaminated toilet Sink were isolated by dilution technique. The dominant bacterial strains are identified as Bacillus sp.‚ on the basis of morphological and biochemical characteristics. Gram’s staining: Gram positive and rod shape. They were serially diluted and spread on nutrient agar plates. The starch has been hydrolyzed and a clear zone by the addition of iodine solution. Visual identification: When bacterial biomass mixed with silver nitrate solution

survivability in artificial gastric juice ABSTRACT: Two probiotic drinks were investigated in vitro to test their ability to survive acidic conditions and their probiotic factors. Both the products: Actimel and Yakult contain gram-positive bacteria‚ but Actimel also has a gram-negative bacteria. The ability to survive was investigated by adding artificial gastric juice to the products and incubating at different times. Actimel and Yakult were both able to survive the gastric juice. Actimel produced
