Kultivointiliemessä

Kultivointiliemessä refers to a liquid medium used in microbiology for the cultivation of microorganisms. This medium typically contains essential nutrients that support the growth and reproduction of bacteria, fungi, yeast, or other microbes. The specific composition of a kultivointiliemessä varies widely depending on the type of microorganism being cultured and the purpose of the cultivation. Common components include a carbon source (like glucose), a nitrogen source (such as amino acids or peptones), salts, and sometimes growth factors.

The liquid nature of kultivointiliemessä allows for easy manipulation, aeration, and the assessment of microbial growth through turbidity measurements. It is widely used in research laboratories for isolating and identifying microorganisms, performing biochemical tests, and producing large quantities of microbial biomass for various applications. Sterilization of the medium before inoculation is crucial to prevent contamination by unwanted microorganisms. Kultivointiliemessä can be prepared in various forms, including broths and liquid agar formulations, though the term generally implies a liquid state. The process of growing microorganisms in such a medium is known as liquid culture or broth culture.
