Downstream processes refer to the processes that take place after the fermentation process of purification to the packaging of the Biopharmaceuticals. Moreover, the issue of quality control techniques in a bid to ensure successful product analysis will receive attention in this essay.
One of the critical steps in the upstream processing is the choice of an effective culture and expression system.There are three types of culture systems that may be adopted in the fermentation process. One of them is the batch culture, which is the commonest culture system that used in many industries because of lack of complications. The fact that batch bioreactors are easily available explains why many companies have exhibited preference for it. Batch cultures need to be loaded with all the required nutrients and substrates, and then inoculated with the selected microorganism. Although it is commonly referred to a closed system, there is an evident need to maintain a measure of exerting control on factors such as pH and aeration. After fermentation runs to completion, product removal follows (Boudreau & McMillan, 2007).
Although the batch system has been highly preferred, it presents certain challenges, especially because of the surging lack of constancy in the producing formation. In the initial phase when the microorganism is undergoing growth, there is no productivity. Moreover, accumulation of the product also limits further production (Buckel, 2001). In other cases, the presence of a high substrate concentration in the initial phase serves as a form of inhibition. In a bid to address this challenge, the development if fed batch where an inflow is introduced was a benchmark of success. Although the batch culture still has some of the outstanding disadvantages of the batch culture, the fed-batch ...Download file to see next pagesRead More

...I disagree with the ment that agricultural biotechnology is promising and can solve the problem of world hunger. I argue that the risks associated with biotechnology far outweigh its purported benefits. Biotechnology in its simplest and most straightforward definition is the modification of the genetic make-up of natural organisms to serve human use, consumption and exploitation. A popular example of biotechnology is the “golden rice” which involves genetic modification for the purported purpose of introducing more nutrients and vitamins, particularly Vitamin A. The genetic manipulation facilitates the production of carotenoids in the grain’s endosperm, thus giving it...

...Clinical Trials, Pharmacogenomics and the FDA What is a clinical trial? Why do we do them? [Hint: is it simply to show “safety and efficacy” or perhaps something more?]. Clinical trials is a method of clinical research, in which the researcher or researchers who directly observe a person or people, and/or who collect data to answer a scientific or medical question about the safety or benefit of an invention. The invention could be a medicine, a toll, teaching concept, training method, or behavioral change. Clinical trials are done to determine whether the new biomedical or behavioral interventions are safe and effective, whether the human subject invention like the diet, physical activity meets its definition. The trial is also... Trials,...

...Biotechnology: Week 8 a. Briefly describe angiogenesis? Do you consider angiogenesis to be a form of tissue engineering? Why or why not? Give two examples of how we could use angiogenesis to treat disease, one by turning angiogenesis “on” and a second by turning angiogenesis “off.” According to The Angiogenesis Foundation (2008, pg. 1), angiogenesis is, “the growth of new blood vessels - is an important natural process occurring in the body, both in health and in disease. Angiogenesis occurs in the healthy body for healing wounds and for restoring blood flow to tissues after injury or insult. In females, angiogenesis also occurs during the monthly reproductive cycle (to rebuild the uterus lining, to mature the egg...

...IDENTIFICATION AND DETERMINATION OF ABSORPTION SPECTRA OF CHLOROPHYLL Photosynthesis is a regulated and a multi-step process. It is the process by which the plants produce energy from the sunlight to produce sugar which in turn is used for cellular respiration to produce ATP, the store of energy of the cells. This conversion of the less used energy into a usable chemical energy is assisted by the green pigment called chlorophyll. The photosynthesis uses the water molecule and releases oxygen molecule. (Tanaka and Makino 2009). The pigment is a substance that absorbs light and the color is produced due to the reflection of the light that is not absorbed. Chlorophyll absorbs all wavelengths of the visible light except the green... AND...

...POSITIONAL ESSAY ON BIOTECHNOLOGY Biotechnology is a widely used term these days. However it has been in practice for quite a while now. We even observe biotechnology in our very own surroundings. For instance the conversion of milk into yogurt is an application of biotechnology so is the fermentation of fruit juices and the use of yeast in baking. These activities have been in practice from ancient times. So no matter how one puts it, biotechnology has been a lucrative field of biology for mankind. Biotechnology is the branch of biology that deals with the application of living organisms and biological processes in aiding and improving...

...Biotechnology Pharmaceuticals and/ or biotechnology companies spend billions and take an average of ten to fifteen years to discover and bring a new drug to the public. The drug discovery and development process ensures that only safe and effective pharmaceutical products are brought to the market. Pharmaceutical companies follow similar pathways for the discovery of drugs. Although each company has its own standards and measures for measuring successful drug discovery, the most appropriate measures are ensured to meet safety and effectiveness standards in patients with little compound attrition.

... Rhetorical Strategies Used in the Film Gattaca The three rhetorical strategies that Andrew Niccol used in the film Gattacawere logos, ethos and pathos. Logos One of the rhetorical strategies used by Andrew Niccol for the audience to be sympathetic to Vincent is logos which is the use of logic or reason in conveying an idea. The rhetorical strategy logos was obviously used in the film to draw sympathy for Vincent when society put so much emphasis in predetermining the destiny of individual just by his or her genetic make-up. Gattaca’s over reliance on logic puts the audience off because it failed to consider other factors such as persistence, will and discipline that would make an individual effective and successful...

...Client’s 7 August Is genetically modified food good or bad? Much has been discussed about the pros and cons of genetically modified food, this paper will shed light upon how genetically modified food can be really useful in eliminating hunger. Countless children succumb to hunger each day in Africa; the problem of malnutrition can easily be solved should human beings start using genetically modified foods. Malnutrition can be slowly but steadily eliminated should genetically modified foods be used on a daily basis. However, the safety testing and regulations are yet to be sorted out for these genetically modified foods as this is a topic of acrimonious debate. Much debate has already taken place over this very debatable topic... 7 August Is...

...Biotechnology: Cloning Due The idea of cloning has been at the heart of any number of science fiction stories over the course of the last century. However, it is not a fairytale; it is, in fact, a reality. The potential to clone cells, organs, animals, even whole individuals, is no longer considered impossible and could very well be a huge part of the future of science and research. How is cloning accomplished? Well that is entirely dependent upon what one is intending to clone; reproductive, cellular, or organ cloning. Dolly, for example, was created through a process using mammary cells of a donor sheep. Human cloning in its most basic form is the act of taking one individual and making an exact biological replica of...
