vedelikukultuure

Vedelikukultuur, meaning liquid culture in Estonian, refers to a method of growing microorganisms or plant cells in a liquid medium. This technique is widely used in various scientific fields, including microbiology, biotechnology, and plant science. The liquid medium typically contains essential nutrients, water, and sometimes other additives that support the growth and proliferation of the target organisms.

In microbiology, liquid cultures are used to cultivate bacteria, yeasts, and fungi for research, diagnostics, and industrial production. This method allows for easy manipulation of the culture, such as sampling and inoculation, and can yield large quantities of microorganisms. The growth rate and density of the culture can be monitored by measuring turbidity, which is the cloudiness of the liquid caused by the presence of microorganisms.

In plant biotechnology, liquid culture, often referred to as suspension culture, involves growing plant cells or small aggregates of cells in a constantly agitated liquid medium. This technique is valuable for rapid multiplication of plant material, genetic transformation, and the production of secondary metabolites. It offers advantages over solid media, such as more uniform growth and easier nutrient uptake.

The success of a liquid culture depends on maintaining sterile conditions to prevent contamination by unwanted microorganisms. Sterilization of the medium, equipment, and environment is crucial. The temperature, pH, and oxygen availability are also critical parameters that need to be controlled to optimize the growth of the specific organism being cultured.
