Total volume required is 40*5= 200 40 tubes 5 ml each that is
200ml of broth is required.
If rehydration is done to nutrient broth 1000ml that is 1litre contains 10gram .so for 200ml in 40 tubes that
1000ml = 10g
200ml=x ?
Cross multiply
X=200*10/1000
=2grams of rehydrated broth is required.
You are asked to make 40 tubes of nutrient broth. Each tube holds 5ml each. What...
You are given 2 nutrient broth tubes each containing a pure culture of one of two Gram Positive bacteria. Unfortunately, the labels have washed off and you are asked to determine which tube contains Streptobacillus epidermidis and which tube contains Diplococcus anginosus. a. Name a technique you would use b. DRAW the expected results used to sort the 2 tubes. Make sure to label your drawings (which is S. epidermidis and which tube contains D. anginosus)
Q1 ) Nutrient broth is referred to as a general purpose medium. Explain what is meant by this statement. When considering your answer, you may wish to consider what substance nutrient broth is prepared from in addition to the further information about microbiological growth media on pg. 45 of the practical manual. ( 1 mark) page 45 => Bacterial growth media – nutrient broth The medium used in this practical session to study the growth of bacteria is a liquid...
You wish to have sufficient TSA to make 10 pour plates. Each plate holds approximately 20 ml of agar. The instructions on the container are that 40 grams are to be used to make a liter. How much dehydrated medium do you need?
You have a tube with 5ml of infected blood that has a concentration of bacteria at 10(8) cells per ml. You wish to make a serial dilution of the blood so when you take 100 ul of the last dilution and spread it on a Petri dish you will have between 30-300 colonies growing on the plate. You have plenty of empty 1.5 ml microfuge tubes, a bottle of sterile water, a p1000 pipettor (100-1000ul) and tips, for the dilutions,...
A. You have been given a tube of E. coli. You are asked to make 1 mL total volume of 10-1 dilution of the bacterial culture. Explain how you would do this. Show all necessary calculations. ____ ml cells + _____ ml water = 1 ml (total volume) B. Next, you were asked to make a 10-2 dilution of the bacterial sample. Explain how you would perform this. Show all necessary calculations. You have bacteria at a concentration of 2...
I need help answering the following microbiology
questions.
1. The three tubes in the image to the right contain glucose and the pH indicator phenol red. The middle and left tubes were inoculated with bacteria, and the right tube was left uninoculated as a control. Which of the tubes show evidence of heterolactic fermentation? a. Left tube Gas b. Middle tube c. Right tube d. None of the three tubes Yellow Red Red 2. Which of the three tubes in...
Suppose you were asked to make 100ml of an Acetic Acid/Sodium Acetate buffer with a pH of 5.73 and a concentration of 0.1M What mass (in grams) of Sodium Acetate is needed? What volume (in ml) of Acetic Acid is needed
phenol is in each of your unknowns. 1. You will be given a nitrophenol solution of concentration 400 nmoles/mL and you will use this stock solution to make a serial dilution as follows: To make the serial dilution you need to prepare 5 tubes with 1 ml water. Next, add 1ml from the 400 nmoles/ml stock to the first tube. Pipette the solution up and down carefully and remove 1 ml of this solution to the next tube. Repeat this...
Methods A. Setting up your tubes: Label (1, 2, 3, 4, 5, and 6) the six 1.5 ml size tubes at your station. Put 25 HL of red water solution into test tube number 1 Put 30 uL of yellow water solution into test tube number 3 Put 40 HL of blue water solution into test tube number 5 B. Constructing color spectrum: Make sure you record action in Table II below: Take 5 L from tube number 1 and...
