  • A Study On Nutrient Agar

    1078 Words  | 5 Pages

    Nutrient Agar To observe the colony morphology, the original unknown culture was streaked for isolation on nutrient agar using the quadrant streaking technique, inverted, and incubated at 37° C for 48 hours. This allowed for observation of the colony morphology. Separation of Gram-positive and Gram-negative The original unknown culture was streaked for isolation on Columbia CNA agar and MacConkey agar using a quadrant streak, inverted, and placed in a 37° C incubator for 48 hours. CNA agar contains

  • The Role of Agarase in Agar-Degrading Bacteria

    1848 Words  | 8 Pages

    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

  • Is A Selective And Differential Media Used To Eosin Methylene Blue Agar?

    951 Words  | 4 Pages

    MacConkey Agar plate Extremely similar to Eosin Methylene Blue Agar, MacConkey Agar is a selective and differential media used to isolate organisms based on their lactose fermentation ability. It contains lactose, bile salts, neutral red, and crystal violet (Leboffe, A Photographic Atlas for the Microbiology Laboratory). Just like the Eosin Y and Methylene Blue dyes in the EMB plate, the bile salts and crystal violet in the MacConkey plate encourage the growth of Gram-negative bacteria while preventing

  • What Is 5. 5 Antimicrobial Agar Diffusion Assay

    751 Words  | 4 Pages

    5.5 Antimicrobial Activity The antimicrobial agar diffusion assay was performed according to disc diffusion method against four bacterial strains; Bacillus subtilis , Shigella flexneri, Escherichia Coli ,Enterobacter cloacae and four species of fungi Saccharomyces cerevisiae, Aspergillus candidus, Aspergillus niger and Pencillium Species.Potato Dextrose Agar for fungus and NAM(Nutrient agar media) for bacteria was prepared according to the accurate composition and immediately after autoclaving,

  • The Agar Of Agar Plate

    2 where that’s at the Agar in the plate shifted to the left side of the Agar plate. As a result, it was a failure. This was an indication to start the experiment portion of lab number 2 over again. The results for lab number 3 was successful. Look at figure number 1.0 on page 17. The plaques are distributed nicely throughout the Agar plates. The plaques are also opaque, large, and without any white spots known as contaminates. Lab number 5 revealed one successful Agar plate with a minor contamination

  • Taxol’s Effect on Rates of Tip Growth and Nuclei Position in Neurospora Crassa

    2889 Words  | 12 Pages

    ABSTRACT The purpose of the study was to detect the rates of hyphal tip growth and nuclei position of N. crassa in influence of drug medium, Taxol. The results of the experiments show that the rate of hyphal tip growth and nuclei position are much lower in drug medium than in the control. Taxol have different effect on growth of tip and distance travelled by nuclei. Moreover, the rate at which the nuclei displace and growth of the tips are dependent on the medium and not on each other. Thus, the

  • Tetracycline and Chloramphenicol Against Serratia Marcescens

    1158 Words  | 5 Pages

    Still holding the vial at a 45 degree angle, the swab was inserted into the vial to soak up the S. marcescens for 10 seconds. Partly lifting the lid of one petri dish, shielding it over top like an umbrella, we inoculated S. marcescens onto the agar growth medium in the petri dish. We repeated these steps 2 more times to inoculate all 3 petri dishes. Once all three plates were inoculated with the S. marcescens we removed our forceps from the alcohol. We air dried them, and then passed them through

    there to prevent the water from evaporating in the microwave, had completely popped off. I cleaned up the mess in the microwave and made the nutrient agar mixture again; however, this time I placed the mixture in a larger beaker and covered it with the top of a sterile petri dish similarly to how I had previously boiled Mr. Goble’s Erlenmeyer flask of agar. Again, after 30 seconds in the microwave, the petri dish lid had come off of the beaker and the mixture had boiled over and onto the microwave. I

  • Case Study: Hibiscus Gellan Gum

    905 Words  | 4 Pages

    1.1. Hibiscus rosa-sinens The mucilage of this plant has disintegrating properties, it contains L-rhamnose, D-galactose, D-galactouronic acid, and D-glucuronic acid [6,28]. Shah and Patel prepared acelofenac ODT by DC using 6% of this disintegrant, the disintegration time was found to be 20 seconds. The results of Swelling Ratio (SR) , angle of repose, bulk density and compressibility index were observed as 9, 26.5oC, 0.65g/cc and 16% respectively [40] which indicates excellent flow and good compressibility
