It is really easy to blame your financial difficulties on money. Yet what some people forget, is that this medium of exchange allowed us to create what we have today. Without something to use as currency there would be no society. A society consists of a group of people working together to create an orderly community. The creation of which would not be possible if the basic things that humans need are not satisfied. Money helps create stability by setting a certain value on all the commodities…

Mtb is classified as a Gram-positive bacteria, and is one of the few bacteria that can be cultured in the laboratory5. Its cell surface is partly composed of various virulence lipids, such as phthiocerol dimycocerosates (PDIMs) and phenolic glycolipids (PGLs). and mycolic acid3. Mtb, like many other bacteria, is capable of sensing and responding to their surrounding environment. It does so via the use of two-component systems, one of which is called PhoPR two-component system6. In order for Mtb…

Cream may have the potential for use as a probiotic carrier because it provides an excellent environment for probiotic bacteria, with the added advantage of having nutritional value.Fatty Acids composition in fermented synbiotic cream, containing one of the two probiotic bacteria ( Lactobacillus acidophilus, Lactobacillus casei ) and inulin (0,1.5, 3%) was evaluated during 30 days for the the15-day interval at 4±1 °C. All chemical characterization were affected by the probiotic bacteria strain…

Video Games: A Misunderstood Medium For many years children and adults have enjoyed a special form of entertainment that provides experiences like no other, the video game. These electronic toys have been on the market since the 1970’s, a recent development, and history has shown that new trends are often targeted as a scapegoat for problems of the time. Currently, the ever growing industry of video games has been the source of such controversy, and is frequently blamed for many of the…

In order to determine the identity of two unknown bacteria, I performed a series of experiments over several days. To begin this process I created a dichotomous key that I utilized as a guide to perform a series of inoculations, while using both selective, and differential media. The series of inoculations eliminated bacterium based on test results until the correct bacteria were both positively identified. On day one of this process I received two bacteria, one labeled 7A and the other…

The objective of this activity was to use the knowledge that we obtained throughout the semester, with the goal to correctly identify two unknown bacteria. Organism number thirteen is Escherichia coli. On the first day, I conducted a gram stain and noticed that the bacteria were pink, meaning that the bacteria are gram negative. I also recognized that the bacteria were rod shaped therefore they were bacillus. I also noticed that the arrangement appeared to be single celled. I also put the…

Streptomyces and Antibiosis From our group, Group 2, nutrient agar plates inoculated with E. Coli, (Images 1.1,1.2), (Images 2.1,2.2), (Images 3.1,3.2) no antibiotic activity was detected. This could be a result of the putative colonies chosen, not being Streptomyces. All selected colonies were white, or pigmented rink, raised and rough. One (1) and three (3) were inoculated with the putative Streptomyces colonies. Plate 2 was inoculated with the control Streptomyces colony. Although it was…

We first needed to collect all the proper materials to conduct the tests on our unknown bacterial sample. To begin the lab, we had to collect a nonpathogenic bacterial sample by swabbing an item or surface inside the biology building with a sterile cotton swab. Our lab group decided to swab a Sharpie permanent marker left at our lab station inside our lab room. We then opened a petri dish and smeared the swab across the surface of the agar several times. Once the bacteria was on the agar, we…

Objective I. To learn how to inoculate the nutrient broth properly in preventing contamination to the nutrient broth and the culture Escherichia Coli. This is done by sterilized the loop and sterilized the neck of the tub with heat from before use and before put the cape on. II. To learn how to do a simple streak of an E. coli culture on a nutrient agar plate with one stroke from start to end like a “Z”. III. To learn how to do a complex streak where we grow E. coli culture on the nutrient…

The physical medium and the mental medium work in an entirely different way. When modern spiritualism came about they dedicated their lives to developing spiritually, they had home circles. In this present world people are pre-occupied with social media additionally mobiles, lending itself more to mental mediumship and less dedication. To explain the difference between physical and mental mediumship, we will look at two words ectoplasm and mind. Lets look at physical mediumship, it requires a…
