Title: Catalase enzyme detection Objective: To understand the function of catalase in cells that produce the enzyme‚ interpret the results of a catalase test and know their value in differentiating bacteria. Materials: 1 clean microscopic slide‚ 3% H2O2 solution‚ swabs. Micrococcus luteus‚ Enterococcus faecalis‚ patient G Procedure: 1) Scrape some cells off from each bateria to the slant and place them on glass slide. 2) Place one or two drops of H2O2. Watch for bubbling as an indication of

conditions. • The airtight equipment used for conversion is known as a biogas plant or digester‚ which is constructed and controlled to favour methane production. i. Stage I: • The original organic matter containing comlex compounds‚ e.g.‚ carbohydrates‚ protein and fats is broken down through the influence of water (known as hydrolysis) to simple water soluble compounds. • The polymers (large molecules) are reduced to monomers (basic molecules). • The process takes about a day at 25oC in

Safety/Science Foundations 1. Avoid the situation; don’t touch 2. Close-toed shoes 3. Students 4. To protect your eyes from chemicals 5. Before starting the lab 6. Students should not play around and follow directions. Students should clean up after their selves after finishing a lab. 7. Hypothesis - a testable explanation for an observation 8. Observation - statement made using senses. ex. I hear chirping Inference - interpretation from observations. ex. "The chirping is from the bird"

LESSON PROPER ALCOHOLIC BEVERAGE Any potable liquid that contains 0.05% to 95% of ethyl alcohol by volume is considered as alcoholic beverage. Two Types of Alcoholic Beverage I. Fermented Alcoholic Beverage Fermentation – Is the natural process where yeast enzymes decompose: Carbohydrates in grains used to make beer and (at the early stage in the production of) spirits/liquors; or‚ Sugars in fruits used to make wine.

the absence of oxygen‚ used for industrial or domestic purposes to manage waste and/or to release energy. The digestion process begins with bacterial hydrolysis of the input materials in order to break down insoluble organic polymers such as carbohydrates and make them available for other bacteria. Acidogenic bacteria then convert the sugars and amino acids into carbon dioxide‚ hydrogen‚ ammonia‚ and organic acids. Acetogenic bacteria then convert these resulting organic acids into acetic acid‚

Background examination for the Dominant Thumb Experiment: • Upon reading the literature that the researcher found by googling‚ "Thumb Dominance‚" they discovered that almost every human being has a dominant thumb whether it be the right thumb or the left thumb on top after naturally clasping their hands together. However‚ if the individual tries to force their clasped hands to let the other thumb become dominant it ’s most often described as feeling awkward or abnormal. In 1999‚ a scientist by the
