However more context would be needed.

Enrichtment culture:
Enrichment culture is the process of using a specific growth medium to encourage the growth of one microbe over others, therefore enriching a sample for the microorganism of interest. Enrichment cultures have been used to raise the number of targeted organisms, which occur in limited numbers, to measurable levels.

Aus der Anreicherungskultur kann mittels besonderer Reinigungstechniken, die die Trennung verschiedener Mikroorganismen (gewünschter von ungewünschten) bewirken, eine Reinkultur (Klon s.u.) angelegt werden.

Eine Anreicherungskultur bietet Wachstumsbedingungen, die für einen bestimmten Mikroorganismus oder eine bestimmte physiologische Gruppe von Mikroorganismen günstiger sind als für andere Mikroorganismen, mit dem Ziel, diese selektiv <b >anzureichern, … Dies wird genutzt, um bestimmte Mikroorganismen zu deren Nachweis anzureichern oder um ihren Stoffwechsel für bestimmte Zwecke zu nutzen.

A microbiological culture, or microbial culture, is a method of multiplying microbial organisms by letting them reproduce in predetermined culture medium under controlled laboratory conditions.

Second, the isolate is cultured on mannitol salt agar, which is a selective medium with 7.5% NaCl that allows S. aureus to grow, producing yellow-colored colonies as a result of mannitol fermentation and subsequent drop in the medium's pH.

Additionally, numerous studies indicate that many small molecules referred to as compatible solutes, such as glutamine, proline and glycine betaine, can intracellularly accumulate in S. aureus due to increased biosynthesis or uptake, and decreased degradation modes, resulting in an improvement in osmotolerance

Multiplication
After attaching to a surface, and in the presence of a sufficient nutrient source, the adherent S. aureus cells will begin to divide and accumulate. … It is this time of cell division and accumulation that we have termed the multiplication stage (Figure 1B).

As expected, there was a significant decrease in the maximal length of wild-type strain SA564 cells during the transition from an exponentially growing culture to a stationary-phase culture (0.873 ± 0.049 and 0.719 ± 0.042 μm, respectively; P > 0.0001).

However, time consuming incubation does not allow for a quick estimation of the number of bacteria in a growing culture. In the present study, the resul...

For continuous cultures sterile fresh medium was added from a reservoir to the growing culture with a peristaltic pump.
