TITLE OF PROJECT: Effects of Chemoattractants of Pseudomonas Aeruginosa Through a Capillary Tube. PROPOSED COST: $1764.90 ABSTRACT: This project will show how strong certain bacteria that are commonly found in biofilms attract to Pseudomonas aeruginosa through a capillary tube. It will test ten bacteria to see which bacteria have more chemoattractants with Pseudomonas aeruginosa . These bacteria are all motile‚ so to come together to form a biofilm‚ they must lose their ways of

When the Antibiotics Quit Working It seems as though antibiotics are slowly losing the battle against infectious disease thus causing a greater demand for researchers to invent new antibiotics that have new mechanisms for killing microbes as well as new vaccines. The problem is that bacteria are becoming resistant to antibiotics. When bacteria are exposed to antibiotics they are under “selective pressure” that allows

Biodegradation is the breakdown of polymer by microbial organism such as bacteria‚ fungi etc. into smaller compounds. The microbial organisms degrade the polymer through metabolic or enzymatic processes. Synthetic plastics are resistant to degradation‚ and consequently their disposal is fuelling an international drive for the development of biodegradable polymers. A variety of natural‚ synthetic‚ and biosynthetic polymers are bio and environmentally degradable. A polymer based on a C-C backbone tends

INTERPRETATION: · Place the metric ruler across the zone of inhibition‚ at the widest diameter‚ and measure from one edge of the zone to the other edge. HOLDING THE DISH UP TO THE LIGHT MIGHT HELP. · The disc diameter will actually be part of that number. · If there is NO zone at all

Black periwinkles are a type of marine snail. Periwinkles may live out of the water for several days and can survive in challenging conditions. Out of the water‚ they can stay moist by closing the trap doors on the opening of their shells. This is called an operculum. Periwinkles are herbivores that feed on algae such as‚ Green algae and diatoms. Green algae is common in areas where light is abundant‚ such as shallow water or rock pools. They use their radular (tiny teeth) to scrape algae off

Microbes in environment and health Micro-organisms are very dangerous but they can also help you. They cure you but they can also kill you. They have been around longer than dinosaurs. They can adjust to almost any environment. There are six types of microbes. There is Archaea‚ Bacteria‚ Fungi‚ Protista‚ Viruses and Microbial mergers. Microbes play a big part in people’s health and in the environment. Good Microbes play a big part in people’s health. They mostly

It functions independently. However‚ multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another. Multicellular organisms

Innovation and technological advancement are two reasons why humanity has come so far from its origins. However‚ could one of mankind’s breakthroughs lead to its downfall? Sickness has its place in history as one of the most prolific killers of people. The Black Plague in the Middle Ages wiped out significant human populations. In the present‚ research in medicine has brought forth antibiotics – a way of stopping harmful bacteria from infecting a person. Growing concern is centered on the fear that

An Ode to E. Coli There is a natural human tendency to dismiss what we cannot see. This idea is based in evolutionary biology. Throughout most of human history‚ threats to our survival have been deadly predators . It is only natural then‚ that we should focus our concern on objects whose importance we can see. For this reason bacteria seem insignificant on the surface‚ its invisibility marking its lack of precedence as a threat. This is a misconception‚ because bacteria hold enormous power. It can

March 26‚ 2013 Methods and Materials (Bread Mold Lab) Block 1 The materials needed to conduct this experiment are six small squares of bread‚ a container of milk‚ four small Ziploc bags‚ a thermometer‚ a phone to record data and a heat lamp. The container of milk will be used for residue on the inside of two of the plastic bags. The heat lamp will be used to generate heat onto the bread towards the possibility of mold. The thermometer is used to measure the heat that the heat lamp is producing;
