concentrations (0.5–5 U/ mL)‚ temperatures (20–50C) and times (30–300 min). The effect of these enzymatic treatments on total phenol content and clarity of the juice were evaluated using a central composite design. The optimum treatment conditions were: enzyme concentration 5 U/mL; time 300 min; and temperature 20C. Their application led to a 40% reduction of total phenols but induced a threefold decrease of the juice clarity. This drawback was overcome by ultrafiltration of the laccase-treated juice

BIOREMEDIATION INTRODUCTION:- The process of bioremediation was reportedly devised by George M Robinson in the 1960 during experimentation with dirty jars and the introduction of microbes this was however not applied until the 1972 clean out of the fuel holding tanks on the RMS queen mary. Science 1972 bioremediation has become greater developed as a means of cleaning up spills of gasoline diesel ‚ heavy metals and other easily degraded petroleum products (National Research Council 1993).

In the lab‚ we use a Biological Media to aid in growth reproduction. Also referred to as a culture medium‚ a Biological Media is a substance used to support the growth of microorganisms. The two types of media most commonly used in Microbiology are selective media and differential

themeniscus shows the temperature against an inscribed scale. Infrared thermometer Infrared thermometers infer temperature using a portion of the thermal radiation sometimes called blackbody radiation emitted by the object of measurement. They’re sometimes called laser thermometers if a laser is used to help aim the thermometer‚ or non-contact thermometers to describe the device’s ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object

"Our infrared dry sauna heats your core directly. So only 20 percent of the heat generated by the far infrared heat waves actually heat the air. So 80 percent of the heat waves that are generated by the heat waves‚ heat your core directly‚" explains Maloney. He explains it causes your body to heat

NMR solvent used and its chemical shifts: Acetone-d6‚ the chemical shifts are 29.9 and 206.7 for 13C Questions: 1. 2. The phenol group of methyl salicylate is a weak acid‚ therefore it reacts very swiftly with a strong base‚ in this case NaOH‚ to form a sodium salt. Which removes the H from the phenol group. During hydrolysis the ester group of methyl salicylate is broken apart by the addition of a molecule of water. From which a molecule of alcohol and a molecule

In class‚ we used phenol red as the pH indicator and the result was a yellow color which indicated that enough acids products have been produced by fermentation (Phenol Red Carbohydrate Fermentation Broth lab handout). Next was the catalase test. After adding hydrogen peroxide to my sample‚ the
