Fermentation

Alcohol is known world-wide to be a mind-altering substance deeply inscribed with culture and historical presence. For this reason, it is not classified as an illegal drug, though it can have quite a few negative effects just like any other drug. With its many uses—both recreationally and medically—it is no wonder why alcohol is the most commonly used “drug” in the world, despite its repercussions when abused. Alcohol does not fall under the list of controlled dangerous substances (CDS) because…

“Our environment, the world which we live and work, is a mirror of our attitudes and expectations” - Earl Nightingale. The world has been around for billions of years and has undergone permanent damage that has been caused by the careless human race. The damage that has been done is irreparable, and it should not be overlooked. The desire to improve our environment and keep our world safe has been a mutual feeling by individuals who are aware of the effects of greenhouse gases. Buying energy…

chemotaxis. Moreover, S. marcescens mutants can be very poor swarmers, defective in swarming or have altered patterns of swarming. The nonflagellate S. marcescens are cable of growing rapidly on agar media (O’Rear et al., 1992). Of the three sugar fermentation tests available a lactose test has been performed to determine if the unknown is capable of using lactose as its carbon source. The results obtained, no color change or gas bubbles, indicate the unknown specimen is not a lactose fermenter,…

Law of Conservation of Mass Have you ever wondered why certain things decompose faster than others? I was interest in doing this project because I’ve always wondered why certain things decompose faster than others, and why they decompose. For my science fair project I want to find out why what types of decomposition there are, and how the process of decomposition works. I like to observe the tiny things in life, and why it works, or why it happens, and I feel like I could gain some knowledge on…

About 68% of people in America listen to the first statistic they hear, and believe whatever the so-called "fact" is, as long as it is coming from a semi official source. The main focus point of the entire narrative is that a very popular weapon used by people who are skeptical of new advancements in agricultural biotechnology claim that there has been little to no evaluation of the safety concerning GM crops, and that there is no scientific consensus on this issue. Those claims as well as the…

(DeLoney-Marino CR, 2013) Vibrio Fischeri is a heterotroph and has the ability to be anaerobic and aerobic which was determined through genome sequencing and chemical assays. One of the ways in which it is able to grow anaerobically is by using mixed-acid fermentation. (Ruby et al. 2005) Vibrio Fischeri is also oxidase positive. Location: Vibrio Fischeri is found in shallow marine environments and has a symbiont relationship with certain squid and fish (see Figure 1). Vibrio Fischeri stops the…

tequila, bourbon ext… All of the alcoholic beverages you can purchase have a different taste, and a different method of making them. “Ethyl alcohol, or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches. It is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine into the bloodstream.” (Alcohol National Institute On Drug Abuse) The process of distilling and…

Antifungal agents.  Echinocandins Echinocandins are the first class of antifungals which target the fungal cell wall, also was a significant achievement in antifungal chemotherapy. Echinocandins discovered during the search for new antibiotics, as fermentation metabolites with antifungal activity. Three semi-synthetic echinocandin derivatives have been developed for clinical use: • caspofungin, • micafungin, • anidulafungin All three types of derivative are structurally similar cyclic…

Refrigeration prevents any damage to the cargo or decay of perishable foods like oxidation, fermentation, and drying out of cargo. As the main purpose of the vessel carrying refrigerated cargo is to ensure the cargo is transported in good and healthy condition, it is uttermost important that the refrigeration system works perfectly at all times. Regulations…

DROPLET PRECAUTIONS These are used for organisms that can be transmitted by close, face-to-face contact, such as influenza or meningococcal meningitis. Droplet precautions include the following: ◊ Place client in private room ◊ If a private is not available, place client with another client who is infected with the same microorganism ◊ Wear a mask if working within 3 feet of the client. ◊ Limit movement of client outside the room to essential purposes. ◊ Place a surgical mask on the…
