Mikrobiviljelyt, known in English as microbial cultures, refers to the process of growing microorganisms in a controlled laboratory environment. This involves providing a suitable medium, such as an agar plate or liquid broth, that contains the necessary nutrients for the specific microorganisms to thrive. The goal is to isolate, identify, and study these tiny life forms, which include bacteria, fungi, viruses, and other microscopic organisms.

The preparation of microbial cultures begins with obtaining a sample, which can come from various sources like soil, water, food, or clinical specimens. This sample is then inoculated onto or into the growth medium. Incubation follows, where the culture is placed in specific temperature and atmospheric conditions to encourage microbial growth. Over time, visible colonies or turbidity may appear, indicating the presence and proliferation of microorganisms.

Microbial cultures are fundamental tools in many scientific disciplines. In medicine, they are crucial for diagnosing infections by identifying the causative agent and determining the most effective antibiotic treatment. In food science, they are used to monitor food safety and to develop fermented products like yogurt and cheese. Environmental microbiology utilizes cultures to study microorganisms in ecosystems and their roles in nutrient cycling. Furthermore, research in molecular biology and genetics often relies on pure cultures to investigate microbial behavior, gene expression, and metabolic pathways. Maintaining sterile techniques throughout the process is paramount to prevent contamination and ensure the accuracy of experimental results.
