you can prepare 20nM sodium phosphate buffer pH7.0.
calculate mass of enzyme and dilute in volume buffer to reach concentration you want.
good luck
When you are looking to make a potassium thicyanate solution you have to dissolve 0.972 g of KSCN in enough H2O to make a 100 mL solution.
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.
To make a potassium thiocyanate solution, dissolve 0.972 g potassium thiocyanate (KSCN) in enough water to make 100 ml.
Calculate the weight of sucrose for the desired volume and concentration of the solution.
a solution
No, E. coli is urease-negative
No. Streptococcus species are not urease positive.
most definitely. it is a strong positive urease producer.
Urease positive means that an organism can produce the enzyme urease, which reacts with urea to produce ammonia and carbon dioxide. This reaction can be detected by the change in pH of the media, typically turning it pink or red. Urease positivity is often used in microbiology to help identify certain bacterial species.
Urease breaks down the compound urea into ammonia and carbon dioxide.
Can you relate urease production to a diaper rash in infants
Proteus urease is considered a positive organisim. This occurs when enterics hydrolyze urea and cause a rapid deterioation. This term is also referred to as rapid urease positive organisms.
Because M.tuberculosis produces urease. thus indicating a person has the bacteria can cause tuberculosis.
Urease enzymes are responsible for the conversion of ammonia to carbon dioxide. It is said to be beneficial to the bacteria because it neutralizes the acidity in the stomach.
Urease!
yes
Urea which is protein substrate
