subjected to disc diffusion assay to ascertain their antibacterial effect. Results Hot water and acetone seed extracts showed considerably good antibacterial activity against all the bacteria except Klebsiella pneumoniae and one strain of Pseudomonas aeruginosa. Minimum inhibitory concentration for aqueous and acetone seed extracts ranged from 20–80 mg/ml and 5–15 mg/ml respectively. Viable cell count studies revealed the bactericidal nature of the seed extracts. Statistical analysis proved the better/equal

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

A certain study also says that the methanolic leaves extracts of the said species was found effective against Pseudomonas aeruginosa (http://www.stuartxchange.org/Dalunot.html). This study hopes to look more into the Dalunot and use the leaves as an antibiotic against Salmonella enterica and Escherichia

Introduction In my report I will discuss what I did as an experiment and what I hope for it to achieve. Firstly I carried out an experiment to assay the effectiveness that a range of disinfectants have on the growth of ecoli and whether or not it can prevent it from growing. From the experiment i should be able to see that some disinfectants have a greater effect than others do. From this I shall then draw a conclusion and evaluation on what was the most effective‚ and could there have been any

Control of Postharvest Anthracnose Using Chitosan and Lemongrass Oil Abstract Anthracnose is a postharvest disease of mango caused by the fungus Colletotrichum gleoesporiodes that results in major economic challenges during transportation and storage. It limits mango production in our country especially where high humidity prevails during the cropping season. Symptoms of this postharvest disease are black spots‚ starting from the stem‚ then proceeding to infect the mango fruit itself. For the control

Pseudomonas aeruginosa Pseudomonas aeruginosa is the bacteria of my initial unknown project. Determining which bacteria I had was completed by many steps. The one fact that I had‚ was that it was a gram negative bacteria because on the gram stain it appeared pink. Its cell wall is composed of a plasma membrane‚ periplasmic space‚ peptidoglycan and an outer membrane (lipopolysaccharide and protein). By looking at the agar plate it was easy to tell that it was not a swarmer and it did not have any

different evidences on the isolation of Pseudomonas from the soil experiment. Firstly‚ the plate count agar is a medium for the enumeration of viable organisms in food‚ water‚ waste water and also from clinical samples‚ and thus it is non-selective to any species. Whereas the CFC agar is a selective agar which contains reduced amounts of cetrimide but also cephaloridine and fucidin are added to allow the isolation of most Pseudomonas species. If the Pseudomonas species are present‚ a blue-green or

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
