protein to decrease the global demands for FBS and to decrease the number of bovine fetuses required for the production of FBS. It is crucial to conduct a study that is not only able to produce protein hydrolysates from tempeh, but also to increase the growth performance of cells when tempeh hydrolysates is tested on cell culture. It is significant since the tempeh hydrolysates can be a good substitute for animal-derived serum such as fetal bovine serum because it is more ethical, cost-effective and environmental
Bacteria alike, different types of bacteria are able to survive and reproduce in different types of environment. Some factors that affect the growth of bacteria include temperature, presence of certain gases and pH of the medium it is in. In this experiment, the variable that was changed was temperature. Temperature is one significant factor that affects the growth of bacteria. Each bacterial culture has its own minimal, maximal and optimal temperatures. Bacteria thrive at their optimum temperature and
colonies of different species. The streaking for isolation technique is a tool used to obtaining a pure culture. The technique consists of taking an original inoculum that contains a mixed culture and spreading the bacteria into four quadrants on a solid medium. The purpose of spreading the mixed culture on a petri dish is to reduce the number of bacteria in each subsequent quadrant to one parent cell of each type of bacteria. One isolated bacterial is called a colony; which consist of thousands or even
because this will prevent air bulb contamination getting into the tube. → Always use separate media bottles to reduce both potential contaminations; limits the spread of contamination and cross contamination with another cell line if the bottle of medium becomes contaminated. → Avoid sharing bottles of media or other solutions with class mates because this can cause cross contamination and also lack of responsibility is started from sharing with others.
provide the favourable condition to the other for growth. These isolation techniques were developed by Robert Koch in 1883 in which he added agar to the liquid nutrient broth. With the addition of agar the liquid media was transformed into the solid media and helped in isolating different bacterial colonies. In this media the nutrient broth supplemented the nutrientinal requirements of the bacteria whereas agar provides the solid substrate for bacterial growth. The pure culture contains a similar kind of
Acne is described as the most common skin disorder that affects 85% of individuals ranging from pre-teenagers to grown adults, specifically between the ages of 12-24 (Tahir 2010). In the midst of the 50 million people affected with acne vulgaris, adolescences are generally most susceptible due to elevated sexual hormones (Zaenglein et al., 2016). Numerous factors increase the production of acne vulgaris. Inadequate diet, menstruation, sweating, over exposure to ultra violet rays and excessive stress
In order to preform this experiment you will need; cotton swabs, agar plates, microscope, unused slides, oil immersion, nigrosin, and crystal violet. The first task we must do is use the cotton swabs and swab an item out side of the laboratory, that has the capability of containing either yeast, bacteria, and mold. My lab partners and I chose to swab one of our group members cell phone. Once we swabbed the phone with the cotton swab, we then each had a plate of agar. To start the process of the transfer
This study aimed to compare the antibacterial quality as well as the effectiveness of different brands of toothpastes marketed in the world, were aimed for reducing the oral bacterial amount. One brand contained triclosan and sodium fluoride as antibacterial while the several of them contained sodium fluoride only and two were herbal. The percentage bacterial reduction or increases was calculated from the differences in bacterial counts before and after brushing. There was an increase in mouth bacterial
bacteria growth. Hypothesis- I think that the concentrations with the most Dettol disinfectant will stop bacterial growth the most. Out of all the percentages I think the 100% disinfectant will stop the bacteria the most, this solution would be made from 10ml of Dettol disinfectant and 0ml of water. Variables- The independent variable in this experiment are the amounts of Dettol disinfectant used for each petri dish, the dependant variables are the measurement of bacterial growth that grows
Figure 1 is an illustration of lab 1, the serial dilution performed for bacteria. This table is describing the number of colony forming units and the observations of the plates per dilution after a week. We didn’t stain the bacteria because time was limited and we would have only determined if they were gram positive or negative. Lab 2. After 72-hours of incubation at 37°C the fungi plates were refrigerated for a week. They were then observed, and a plate count was performed. A geometric mean
pressed firmly so they don’t move, and then incubated. Presence of zone of inhibition around the disc it means bacteria was sensitive to the drug. Basically zone of inhibition is the area formed around the antibiotic disc, which is the area of no growth and it is a clear zone.
hydroponics. During the 1940’s at Purdue University, Robert B. and Alice P. Withrow developed another hydroponic method. Their process was called Nutriculture. Nutriculture varied from Dr. Gericke’s method in that gravel was used as a rooting medium. After World War II a number of commercial installations were built in the United States. The majority of these were located in Florida. Most were out of doors and subject to the rigors of the weather. Poor construction techniques and operating practices
productivity growth in non-durable manufacturing decelerated in 1995-9 compared to 1972-95, but productivity growth in durable manufacturing stripped of computers has decelerated even more." What should be held true - the hype or the dismal statistics? The answer to this question is of crucial importance to economies in transition. If investment in IT (information technology) actually RETARDS growth - then it should be avoided, at least until a functioning marketplace is there to counter its growth suppressing
"Love is whatever you can still betray. Betrayal can only happen if you love." (John LeCarre) In William Shakespeare's The Tragedy of King Lear, characters are betrayed by the closest people to them. The parents betray their children, mostly unintentionally. The children deceive their parents because of their greed and power hunger. Their parents were eventually forgiven, but the greedy children were not. Parents and their children betray one and other, and are only able to do so because they are
closely examined the relations and functions of such concepts in their book, Remediation: Understanding New Media. Both immediacy and hypermediacy are terms referring to logic, the imperative on which the relationship between the engager and the medium rests. Immediacy refers to the producer’s goal of the text’s mediation being rendered transparent. Immediacy is associated with simultaneity, intuition and invisibility, and attempts to erase its representative qualities to provide ‘immediate’ a.
Language as Freedom in Sartre's Philosophy I argue that Sartre posits language as a medium of communication that is capable of safeguarding the development of subjectivity and freedom. Language does this in a twofold manner: on the one hand, it is an action that does not phenomenally alter being, but that has the capacity of altering consciousness; on the other hand, language, more particularly written text, is a mode of communication that is delayed, hence that occurs outside the present, i.e
A Detailed Business Report of One Medium Size or Large Business I have been asked to produce a detailed business report of one medium size or large business. My well- planned business report should contain: Ø The objectives, organisational structure and communication channels that operate within the business. Ø An examination of how these factors, interrelate in a way that can affect the success of the business. Ø An explanation of how quality assurance and control assurance and control systems
The field of technology has seen continuous growth and advancement in society and has changed gears and is now heading for a road less traveled. The road, as bumpy and winding as it seems, as following a path dictated by television and all the powerful media. The television requires visual perception and is an inactive form of gratification for viewers. The hardest hits are the young children. Children shows like cartoon have positive and negative effects on the children, and the parents should not
Hypertext as a Medium for Writing This paper will compare and analyze theoretical ideas found in Hamlet on the Holodeck by Janet H. Murry focusing on Chapter 10 “Hamlet on the Holodeck” as it relates to hypertext as a specific medium for writing, and Writing Space by Jay David Bolter focusing on Chapter 7 “Interactive Fiction” and chapter 8 “Critical Theory in a New Writing Space” and their emphasis on digital poetry and the increased role of the reader in the reading process. The information
aan elkaar gerelateerde feiten over Godard en zijn 'A Bout de Souffle' die de film tot een nieuw historische mijlpaal maken op het gebied van de kunst (met name de audiovisuele kunst). Ten eerste, was Godard extreem bewust van de relatie van zijn medium met andere vormen van expressie. Vooral literatuur, filosofie en de schilderkunst. In zijn stijl valt deze 'interconnectiviteit' tussen de verschillende media duidelijk op te merken. In een interview in 1962 zegt hij: "Voor mij is de continuïteit
