How would the pH of the culture medium be influenced by sugar fermentation?
If it ferments a sugar, the pH drops (becomes more acidic) -- lower pH #
A substance with a pH of 11 is what times more what than a substance with a pH of 8?
A pH of 11 is 1000x more alkaline than a pH of 8. The pH scale is a logarithmic scale. This means that in a pH scale, a change of one whole number represents a tenfold change in the pH. So a pH of 8 is 10x more alkaline than a pH of 7.
Change in the pH should the enzyme?
If you change the pH, the enzyme can become inactive and won't be able anymore to forfill its function.
Why does acid clot appear pink or white with a pink band at the top?
Litmus milk is an undefined medium consisting of skim milk and the pH indicator azolitmin. Azolitmin is purple between pH of 4.6 and 8.2. It turns pink when pH reaches 4.5 and blue at a pH of 8.3. Lactose ferminatation turns the litmus pink due to acidity. If litmus is reduced during lactose fermentation it will turn the medium white. Acid may cause an acid clot this is due to the casein precipitating. Heavy gas production can cause stormy fermentation, this is due to the breaking up of the clot.
Identify two factors that could cause enzyme denaturation?
Temperature and pH are the two factors that can cause enzymes to denature.
Does the pH of the media change during sterilization why?
The pH is dependent on the temperature.
How can one remedy the effect of pH CHANGE due to sterilization?
The effect of pH change due to sterilization is that it cold altered the media
Does the pH change during the course of the fermentation?
the medium becomes acidic
What does a color change in an acid-base titration mean?
according to change of PH of medium where the indicator color is changed according to PH of medium
Can calcium chloride damage plants?
yes. it dissolves in water and can change the pH of the medium
What is a bioindicator?
A biological indicator is a device to monitor the sterilization process that consists of a standardized population bacterial spores known to be resistant to the mode of sterilization being monitored. Biological indicators indicate that all the parameters necessary for sterilization were present.
Does pH level change during pregnancy?
Yes, more alkaline
Why does the medium's pH need to be standardized at 5.8 while preparing the MS medium?
Because it is the pH of the Apoplast. Cells are happy in it.
What is the pH of filler?
It is a acidic medium . . .
Why is the pH of the medium important in edta titration?
why is the pH of the meadium important in EDTA titration
During periods of physical exercise there is an increased production of carbonic acid does the pH body fluids rise or fall?
The Ph in your body would not change
What will lowering the pH of a medium do to the angle of refraction of light?
Lowering the pH of a medium, such as a liquid, will not have a direct effect on the angle of refraction of light. The angle of refraction of light is primarily determined by the refractive index of the medium, which is not inherently influenced by pH changes. However, extreme changes in pH may induce changes in the optical properties of the medium, potentially leading to alterations in the refraction of light.
