A microbial ecologist wants to study a bacterium that is adapted to growth in lake water containing very low nutrient concentrations. Assuming that a suitable growth medium is available for this organism, which type of culture would be best to use for growing this organism in the lab

Hello. You forgot to enter the answer options. The options are:

"A) This organism cannot be grown in the lab.  B) a batch culture using a low-nutrient medium  C) on Petri plates containing a low-nutrient medium  D) a chemostat using a low-nutrient medium"

D) a chemostat using a low-nutrient medium

Explanation:

The most appropriate culture medium for this bacteria to be grown in the laboratory is a chemostat using a medium with low nutrient content. This is because this culture provides similar resources to the resources that this bacteria finds in its natural habitat. Thus it would be possible for these bacteria to develop in the laboratory, presenting characteristics similar to those it presents in nature, allowing the full study of this microorganism.

Culture media products prepared to provide nutrients necessary for the growth of microorganisms outside their natural habitats. These media are prepared in laboratories and are essential for all branches of microbiology.
