Question

D Question 6 1 pts Why is the concentration of glucose ten fold less than that of either lactose or sucrose in the TSI agar test? The lower concentration permits detection of utilization of only this substrate. If the dextrose concentration were as high as sucrose and lactose, it would be toxic to the bacteria. Dextrose is an acidic compound. Too much will artificially color the slant yellow Since dextrose is a monosaccharide too much would permit the bacteria to use itas the sote carbon source evernrif they are capable of using other carbon sources

Explanation / Answer

Since dextrose is a monosacchride, too much concentration would permit the bacteria to use thsi carbon source even it is capable of using other carbon sources. the concentration of glucose is 0. 1%. This test is used to find out the lactose and sucrose fermenting bacteria. If glucose is high those bacteria which uses glucose will also grow.
