Protein signals cause cells to divide in a culture medium.
In pour plate technique the culture to be grwon is pour in melted agar medium, now when we add the diluted sample in agar plate and if the melted agar is very hot, it can lead to the damage of bacterial or fungal cell and may cause in abruption of growth, so the agar is cooled to get the optimum temp. for growth of microbial cell.
Urea hydrolysis produces ammonia, which can increase the pH of a culture. As ammonia accumulates in the culture medium, the pH becomes more alkaline due to its basic nature. Monitoring the pH of a culture can help understand the progress of urea hydrolysis and the resulting changes in the culture environment.
In a glucose-peptide medium, bacteria ferment glucose into acidic byproducts (such as lactic acid). However, as the bacteria consume peptides, they release ammonia, which acts as a base and neutralizes the acidic byproducts. This results in a net increase in pH in the medium.
Cause there is nothing to divide.
what might cause a culture today to decline or disappear
The Human factor
Cause janna said.
When people don't try and help, that is probably a big factor as why depression could be a cause of suicide.
a medium i bleive my mm is a 11 and she wears a medium in mens cause mens are more comfortable
