Sterile Saline (0.9% w/v NaCl) Dissolve 9.0gm of NaCl in 1000ml water and dispense 9.0ml of the solution into 20ml test tubes. Autoclave the tubes as per the validated cycle and cool to room temperature. Sterile saline with polysorbate 80: Dissolve 9.0gm of NaCl in 1000ml water and add .5gm of tween 80 to the resulting saline solution, dispense 9.0 ml of the solution into a number of 20ml test tubes. Autoclave the tubes Preparation of Inoculums and its Standardization: 1) Take loop full of…

3.0 Hypothesis I assume that as the solution is treated with higher amount of fertilizer, the Spirulina cells will reproduce better and survive for longer time as there will be higher amount of nutrients supplied. Therefore, it is assumed that the Spirulina-concentration of the trials treated with 1.0mL fertilizer will be higher than those treated with 0.5mL or 0.0mL. Although wastewaters contain elements which are vital for the Spirulina growth, as it contain other unknown substances as well,…
Results and Discussion A. Diffusion of selected plant pigments In conducting the diffusion of 4 different kinds of treatments (distilled water, distilled water placed in boiling bath, vegetable oil, heated vegetable oil), the researchers made use of the atsuete and sugar beets. The different kinds of treatments determined how the temperature will affect the color intensity of the atsuete and sugar beets. There were 4 test tubes used in each atsuete and sugar beets with each having a…
5.4. Electrosensitive hydrogels Hydrogel swells in response to an electrical stimulus with a mechanism very similar to pH, experiences shrinkage, and bending. The major difference between electrical and pH stimulations is that the electric field moves mobile ions in order to regulate an ion concentration gradient through the hydrogel and the solution [54,55]. Polymeric networks containing ionizable groups can have important electrical behavior under an electric field. The electrosensitive…
Surfactant Agents I. Definitions a. Surfactant: A surface-active agent that lowers surface tension i. Examples 1. soap 2. detergent b. Surface Tension: Force caused by attraction between like molecules that occurs at liquid-gas interfaces and that holds the liquid surface intact i. Units of Measure: dynes/centimeter (dyn/cm) 1. the force required to cause a 1 cm rupture in the surface film ii. a droplet forms because a liquid’s molecules are more attracted to each other than the surrounding…
STEPS IN BALANCING REDOX EQUATIONS 1) Assign the Oxidation Numbers The Oxidation Number (ON) of an element is its charge. It is the number of electrons an element contains. This would be our basis on whether the element gained or lost electrons in chemical reactions. We can say that an element is in its Oxidation State when the element already has a specific ON. Unlike with our previous examples, not all equations would already reveal the ON of each element. In actuality, equations would…
What is a laccase? Laccases (EC 1.10.3.2, benzenediol: oxygen oxidoreductase) are monomeric, dimeric or tetrameric glycoproteins that are typically extracellular and categorized as multi copper oxidases (Mate and Alcalde, 2016a).They catalyze the oxidation of compounds that are coupled with the four-electron reduction of "O" _"2" "to" "H" _"2" "O" . They are regarded as eco-friendly enzymes. Laccases have been first discovered in 1883, which makes it one of the oldest enzymes ever observed…
The role of oxysterols in human body and disease 1. Introduction Oxysterols are 27-carbon derivatives of cholesterol created by spontaneous or enzymatic oxidation (Figure 1, (Brown and Jessup, 2009)). The oxidation of cholesterol occurs either on the side chain or on the sterol core. Side chain oxidation generates, e.g., 24-hydroxycholesterol (24-HC), 25-hydroxycholesterol (25-HC) or 27-hydroxycholesterol (27-HC) while the core oxidation gives rise to ring oxysterols, mostly ring-B oxysterols,…
