Lab 11 Methodology By using aseptic‚ a little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology

Einston Vue Mr. Andrews AP World History 19 October 2014 From the 5th C.E. century to the year 1325‚ the spread of Islam occurred in the trans- Saharan area in Africa. The spread of Islam impacted many of these societies‚ affecting the rule of kings‚ changing the daily lives of many people‚ and changing the religions. However‚ these changes did not transpire by themselves. The spread of Islam was possible because of the trade and merchants in the Sahara‚ the many kings and their servicemen‚

facilitates the handling of large numbers of bacterial clones for classification on a variety of media. METHODS Replica plating. A frequent chore in bacteriological work is the transfer of isolates from one substrate to other selective or indicator agar media. In place of an inoculating needle‚ one might imagine a device consisting of many needle tips in fixed array‚ so that one operation would substitute for repeated transfers with a single needle. The requirements of this design are met by pile

and starch agar. OBJECTIVES: distinguish between different bacterial species based on colony morphology on agar plates To distinguish the growth characteristics of microorganisms in various differential‚ and selective media. Differentiate bacteria based on their ability to hydrolyze starch. Materials: Plates of EMB‚ Starch and blood agar. Stool sample. Inoculating loop. Bunsen burner. Soil sample. Cotton soap. Skin sample. Gram iodine. Results: Starch agar: Special

Materials: 4 sterile cotton swab‚ sterile water in test tube‚ 4 agar plates and 2 blood agar plates‚ wax pencil and labels. Procedure: Appropriately label the cover of each plate as indicated in lab. 1. Determine 2 sampling sources‚ one from your body and one from the surrounding environment. 2. For the first agar plate‚ for sampling from air‚ remove the lids from the plate and allow it to sit uncovered for 15 minutes. 1. For second agar plate‚ open the “stick” end of the sterile cotton swabs to

observable microbial colonies on the surface of the Agar solid‚ as to determine the presence of microbes in consumable products i.e. yoghurt and blue vein cheese. HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products) will remain free of contamination and microbial growth. MATERIALS: - 3x Agar plates - 10g of berry yoghurt - 10g
Free Bacteria Agar plate Petri dish
An agar plate is a Petri dish that contains a combination of agar and nutrients that help microorganisms grow. The proper method of setting microorganisms on an agar plate is know as “streaking”. In order to streak‚ the microorganisms are placed on a sterile swab or metal wire‚ which is then dragged lightly against the agar solution‚ leaving behind the microorganisms. The amount of organisms is greatest at the beginning
