what are the two problems with culturing in the lab?

Answer 1

Culturing in the lab breeds bacteria that are the most efficient in reproducing and consuming the plenty available food.

Bacteria in real conditions usually have more limiting factors like competition and lack of resources. This means that wild-type bacteria are more hardy but due to the hardiness they reproduce slower. This is an example of survival of the fittest, the ones who are the most fit in a specific environment will be the dominate type.

The problems created is that the cultured bacteria do not necessarily accurately show the characteristics of bacteria in the wild. If you are intrested in learning about the bacteria and how it grows in the wild you can't sue cultured bacteria.

Another problem is that the growing medium grows most types of bacteria and other microorganisms very very well. This leaves great potentional of contamination if you're not very careful.

Answer 2

Cross contamination would be the most common especially when dealing with a large number of strains. there is also the fact that in a lab setting we are not able to measure the true growth of the bacteria in question. this is due to a number of factors which include high nutrient availability and optimum temperature, this means that we are creating a number of artificial parametres for growth to occur.

Answer 3

One problem is that not all bacteria can be grown in pure culture in a lab. Some are only able to grow in the natural environment, not in a synthetic one.

Answer 4

could cause contamination, and it does not always measure the growth of a nicroorganism accuretly
