Suspended culture is a method used in biology to grow cells or microorganisms in a liquid medium. In this technique, cells are dispersed throughout the liquid, allowing them to access nutrients and oxygen while remaining in motion. This method is commonly used in research and industrial applications, such as producing vaccines or enzymes. In suspended culture, the growth conditions, such as temperature and pH, are carefully controlled to optimize cell development. This approach contrasts with adherent cultures, where cells grow attached to a surface. Techniques like bioreactors are often employed to maintain the ideal environment for suspended cultures.
