Each colony is a mass of bacterial clones, usually founded by one individual cell. So each colony represents one original microbe.
A group of bacteria that grew from another colony forming unit.
false
The bacterial growth curve is usually exponential in shape just like most of the living organism.
This is one part of a two part answer. Q: Does each discrete colony represent the growth of one cell? Explain your answer. Why can a single colony on a plate be used to start a pure culture? A: No because a discrete colony is the growth of the descendants of a single cell. The cell will self replicate it self on the growth medium to produce more copies of it self thus creating a colony. A single colony has many cells in the colony. Cells from the colony can be extracted and then placed in a pure culture for better growth. A.C.
because the growth of the unknown bacterial colony will create a pattern when it is grown that is characteristic and can help identify the unknown organism
they need oxygen and heat and moisture to live.

2. The bacteria may release a substance that prevents mold growth.

Bacterial hand wash favors the growth of bacteria on the surface of the skin ( hands). On the other hand ( no pun intended) ANTI bacterial hand wash does not favor bacterial growth and in fact contains agents to prevent any bacterial growth on the hands.
The "danger zone" for bacterial growth are temperatures between 5 and 60 degrees
because the growth of the unknown bacterial colony will create a pattern when it is grown that is characteristic and can help identify the unknown organism
No, drug tests are designed with things such as bacterial growth in mind.
by distorting it
they need oxygen and heat and moisture to live.
inhibit bacterial growth
