Question

Creating conditions in the laboratory that promote the growth of some microbes while inhibiting the growth of others is called ______

A) selective enrichment culturing.
B) complex culturing.
C) differential culturing.
D) transport conditions.
E) reducing conditions.

Answer 1

Selective enrichment culturing(a) is the process of creating conditions in the laboratory that promote the growth of some microbes while inhibiting the growth of others. Selective media are used to inhibit the growth of unwanted microorganisms and support the growth of the organism of interest.

Step-by-step explanation:

Creating conditions in the laboratory that promote the growth of some microbes while inhibiting the growth of others is called (a) selective enrichment culturing. Selective media are used to inhibit the growth of unwanted microorganisms and support the growth of the organism of interest. These media contain substances that interfere with the growth of certain bacteria while promoting the growth of others. An example of a selective medium is MacConkey agar, which favors the growth of gram-negative bacteria while inhibiting gram-positive bacteria.
