(2013) reported a method for isolation of E. coli O157 from meat sample. Twenty five grams of meat sample was blended with 225 ml of sterile modified tryptone soya broth containing vancomycin (40 μg/ml) followed by incubation at 37 °C for 18 h. Enriched culture was plated onto sorbitol MacConkey agar supplemented with cefixime and potassium

different cultures were observed. In order to proceed identification‚ those cultures were isolated as separate organisms‚ using inoculating streak technique and incubated until the next class period. The expected result was supposed to show Gram positive and Gram negative bacterium growing on a separate media. Having checked two Nutrient plates‚ signs of visible growth of two different bacterium were present. Due to the fact‚ that one type of bacteria didn’t appear to be fully

In the video “Into Nepal – A Journey through the Kathmandu Valley‚” there were many concepts that were easily recognizable due to the information that was given during the first semester of the AP Human Geography course. The Hindu people who are pictured in the video segment‚ Budanilkantha: A Hindu Wedding‚ are practicing a custom of many Hindu people. A custom is the frequent repetition of an act‚ to the extent that it becomes a characteristic of the group of people performing the act. Although

how the bacteria function. Over a two week period‚ eight prepared types of test media were provided to identify the assigned unknown mixed cultures. Not all of these tests were performed on every culture‚ as some were used only for gram positive or gram negative bacteria. The tests performed and what constituted a positive or negative test are as follows: Lab day 1; today in lab we obtained the unknown mixed culture “041”and one brain-heart infusion agar (BHIA).

unknown material was tube number twenty. I did a gram stain‚ oxidase test‚ and used three different medias to narrow down and identify my unknown organism. The first step I took in identifying was a gram stain. This gram stain would reveal whether my organism is gram positive or gram negative which would narrow my choices from fifteen options down to six. After completing the gram stain‚ my unknown was the color pink. This revealed my unknown as being gram negative. I also used the microscope to identify

Jody Kaur Pure Cultures Lab 1/31/13 Introduction : Pure cultures are made of only one type of organisms and can be used to study their properties. A method used to isolate pure cultures is making a steak-plate‚ which is a dilution process in which culture is spread over an agar plate in a certain manner. Using a loop rod‚ culture was taken from the tube and dragged across area 1 several time‚of the agar. The agar was then turned 90º‚ and the loop was flamed and cooled. Taking some culture

The identification of the unknown culture was accomplished by identifying the bacteria based on its specific metabolic characteristics and morphology. It is suggested that culture 11 is a sample of Enterobacter aerogenes. Introduction: This experiment was centered on metabolic and biochemical testing
