Flowing water can slow down bacteria

        In the Massachusetts Institute of technology a recent discovery has been made. (I felt like this tied in with what we went over in class on tuesday; about the different places where microbes live and thrive.) It turns out that you are less likely to find bacteria in moving waters, but you will find them attached to surfaces in those waters. This surfaces can be rocks, wood or any other object in the water. The flowing water can have two significant effects on microbes: Stocker says, "It quenches the ability of microbes to chase food and it helps microbes find surfaces.” 

The flow of the water determines the amount of microbes in it!

        In previous studies of microbes in water, researchers have never really taken into consideration, “the flow” of the water. This can play a crucial role, because it could be feeding the microbes or killing them. It makes us realize how much of an effect flow has on microbes.

        In their experiment they used tubes as the object in the water. They noticed that the bacteria would stick to the walls of the tube and create a biofilm, but this effect changed with the flow of the water. For lots of biofilm to form their needed to be a pretty high flow. 

        This information is great, because with this knowledge they can design medical equipment with slow rates of flow in order to prevent microbes from attaching to the tubes and growing; or it can work the other way around. Now that they understand the concept of microbes and flow they can manipulate it, to their convenience. This new discovery is important, because bacteria the builds a biofilm is 1,000 times more resistant to antibiotics. It is important to prevent the growth of microbes before they create their biofilms, because it is a lot easier and safer.

Garlic, More Powerful Then You Think

        Tim Holm Jakobsen, a PhD student at the Faculty of Health and Medical Sciences has recently discovered a remedy for killing resistant bacteria that can be hard to get rid of with the average antibiotic. 

Garlic, more powerful then you think

        We all know their are helpful Bacteria and harmful bacteria. Whether that bacteria is good or bad, it doesn't matter. Bacteria is always developing, and bad Bacteria are developing resistance at an alarming pace. So, new pharmaceuticals that can combat this threat are in great demand. Luckily for us a simple vegetable that can be found in our kitchens is the solution for these hard bacterial strains. What is this vegetable you may ask? Garlic, that yummy vegetable that leaves behind that great scent in our mouths. (Just kidding, I hate garlic!) Garlic has a potent chemical compound known as, “ajoene,” that neutralizes resistant bacteria, by paralyzing their communication system. When it paralyzes their communication system it prevents the bacteria from releasing a toxin known as rhamnolipid which destroys white blood cells in the body. White blood cells are crucial to our immune systems, because they fight off infections and kill harmful bacteria. 

        Bacteria clump together in a tough biofilm made up of organic material; this makes them resistant to the average antibiotic. Tim Holm Jakobsen explains that, “When we add antibiotics to biofilm they have very little effect, and ajoene alone barely makes any difference. It is only when the two are combined that something significant happens,”. In simple words ajoene, which is found in garlic, can help antibiotics kill the harmful bacteria in our bodies. 

        Although this new science is just beginning, their is a great demand and a lot of money in trying to cure illnesses. What better way then natural substances; In fact  2/3 of all new pharmaceuticals are based on natural substances. We know now that garlic is a great natural substance, but how much ajoene do we need for it to help the antibiotics? Garlic contains very little ajoene, in fact you would have to eat about 50 a day for it to reach its effect. Perhaps we could just extract the ajoene that we need, and mix it with the antibiotic. Why make stronger antibiotics that could or could not work, when the answer can be found in garlic. I'm just saying, go with what works and make it better!

Blog 4 - Microbes on Airplanes

        After writing my, “A day in the life of a microbe,” essay; on the common cold found in airplanes. I decided to expand my search on what other microbes can be found on airplanes. 

A flight attendant sprays disinfectant onboard

        Sure enough I was not disappointed in what I found and it turns out that airplanes are dirtier then we think. I mean think about it, they travel from state to state; many airplanes even travel from country to country. This allows for many viruses and bacteria to spread and very quickly. The author Douglas Wright made it very clear and explained very well what each of the following microbes can do and where they can be found. He simple put out the facts and supported them with concrete evidence.

        Many of us don’t even think about how dirty planes are. In your seat alone you can find, influenza A, B, and C viruses. This is also known as the flu and it is linked to between 3,000 and 49,000 deaths and 200,000 hospitalizations each year in the United States alone.  In the trays that many people eat off of, you can find MRSA, which is deadly superbug! (People eat off this) The MRSA is a flesh eating bacterium that is very hard to cure and is really resistant. 

        You know that very yummy food you had on the airplane? Well it turns out it might have Listeria, a microbe known to cause gastrointestinal illness and meningitis. In 2009, the meals made headlines when the FDA inspected the world's largest airplane carriers; American Airlines, Delta and United. They found the kitchens crawling with roaches too numerous to count and employees handling the food with bare hands or unwashed gloves. (Yum!) Another thing to be careful for is the water. In 2004, a random sampling of 327 unnamed domestic and international aircraft caused a stir when some water samples tested positive for E. coli. 

        When your getting sleepy and your flight attendant offers you a pillow or a blanket; think twice before you say yes. These blankets and pillows have been used by other passengers who where also sleepy and tired in previous flights. In 2007 an investigation by The Wall Street Journal revealed that airlines cleaned their blankets every 5 to 30 days. Germs like Aspergillus niger can be found; these germs can cause pneumonia and infections like, lung and eye infections.

        Next time think twice before using airplane resources; if possible bring your own water, snacks, blankets, etc. Alway remember to wash your hands to avoid getting sick and try not to touch everything.

New biofuel sources that don't require farmland

Bacteria used as energy

http://www.popularmechanics.com

        Just recently science has turned to farmland crops such as corn and soy for fuel, but to grow enough to use it as fuel takes extreme amounts of land. Fortunately, a new discover has been made, which is faster and it doesn't require removing valuable farmland form the food production chain. This new discover is a biofuel, made from bacteria. More specifically Streptomyces. Streptomyces is the main candidate for this new biofuel, because it can store large amounts of oils called triacylglycerlos (tags). These oils are direct precursors of biodiesel. Not only that, but manufacturers already know how to grow huge amounts of it, because it is also used to make life-saving antibiotics. 

This has caused lots of debate, because of its significant impact on Mother Nature. Some argue for a cleaner source of energy and others don't want to change from the traditional petroleum, but with the price of oil rising at a steady rate, it is time for new fuel alternatives. Some of these alternatives are crops, solar, wind and water, but unfortunately they all take up lots of space and some even damage ecosystems. So what this article is trying to push is a new alternative energy that doesn't require so much land, and the solution is bacteria biofuel. This new biofuel is safer and less expensive. It is also cleaner for the environment and easy to make in huge quantities.

I would have to agree with the American Chemical Society, because although we have found different alternative energy, it has not always been the best. For example hydraulic energy has been known to kill hundreds of fish and destroy their ecosystems, because of the dams. Another example is Solar energy, it has been proven to work, but it takes up huge amounts of land for the panels. When that land could be used for something else. On the other hand, Bacteria biofuel is easy to produce in large quantities and is very effective and powerful. It doesn't require much land and is safe to the environment. 

        So I do agree, that bacteria biofuel is the way to go, because of its benefits and it's potential to power the world and help it at the same time. What better way to make a change!
