milk intolerant. Other parents may prefer a plant based diet reducing cholesterol and fat consumption. Paleo Diet Alternatives to cow's milk: - Coconut Milk: Paleo friendly alternative to cow's. Plant based from the milk of coconuts. Dairy free, lactose free, gluten free and soy free. Source of calcium and vitamin B12. Good for baking, in cereals and shakes. - Almond Milk: Plant based cow's milk alternative. From the almond nuts creamy and has a nutty taste. Good source of calcium…

In medical or science field, biochemical test are used to identify unknown bacteria. In this case three test are essential to identify the unknown #63 and they are MAC agar test, BCP (lactose) broth and SIM deep medium/slant. Methods such as streak plate technique, aseptic technique, and proper handling of the microbe are necessary to apply when conducting these biochemical test. Contamination during the unknown lab project shows carelessness and may put patient in jeopardy due to incorrect…

Chocolate Chocolate is the snack that everyone enjoys but why those who are lactose intolerant can’t enjoy it as well? What does chocolate really contain? Does it have some ingredient that we should worry about? Why can’t a dog digest chocolate? Is there a way for someone who is lactose intolerant to digest milk chocolate without having any negative effects? It is said that chocolate comes from a cocoa bean but how is it transformed into a delicious chocolate bar? Many civilians love to devour…

Gene Expression Paper RESULTS The hypothesis is that as the amount of lactose increases in a treatment, the higher the enzyme production and activity. A total of six treatments were done in order to determine whether the amount of lactose in a substance correlates with the amount and production of b-galactosidase. Experiment 1: The use of OD600 as an indicator of bacterial population size. In addition, the use of Abs 420 as an indicator of protein production. Then the Miller units of…

other enzymes would denature at a pH of 2 because they belong in an alkaline environment with a pH of 8 and not an acidic environment with pH of 2. Lactase is a great example of this. Lactase is the enzyme that catabolizes (breaks down) the sugar lactose (a disaccharide) into the two monosaccharides, galactose and glucose. Lactase is mostly found in the small intestine, where the pH is around 7. Therefore it is reasonable to hypothesize that human lactase is optimally active at 37 ˚C and at a…

the microorganisms were able to utilize lactose, so the focus will be on their lactose gas production instead. It was observed that the Micrococcus luteus Durham tube had no gas by-product, therefore there is no lactose gas production. It was observed that the Citrobacter freundii Durham tube had a gas by-product, therefore there is lactose gas production. It was observed that the Hafnia alvei Durham tube had no gas by-product, therefore there is no lactose gas production. It was observed that…

contained endospores. When tested, microbe C did have endospores. Table 4 describes selective media tests. EMB was used for lactose fermentation and growth of gram-negative bacteria . Microbe A and microbe B turned dark purple and were able to produce lactose fermentation while Microbe B was not able to turn purple but pink which was interpreted as a negative result for lactose fermentation. PEA test was used…

A chemical reaction is the change of a molecule from one arrangement to another. Our whole bodies are made up of cells, which are chemical systems. To sustain life there must be chemical reactions all throughout the body (Barnhart and Hopper 2011). At what rate the reaction can occur is dependent on the activation energy. Activation energy is the amount of energy the reactant molecules must surpass for the reaction to occur (Mathew Bui et al. 2006). Temperature and catalysts are the most basic…

The purpose of performing physiological tests is to figure out certain characteristics of microorganisms or to reach a conclusion on what an unknown microorganism is. It can be also used to determine what is needed for bacteria to be cultured in or on certain media. Culture media can either be liquid or solid, and they can be used to identify certain characteristics of different bacterial species. This is indicated by the growth or lack of growth in or on certain media. Solid media can also be…
