Bacterial culturing is a laboratory technique used to grow and multiply bacteria under controlled conditions. This process typically involves placing a small sample of bacteria onto a nutrient-rich medium, such as agar plates or broth, which provides the necessary environment for growth. The cultures are then incubated at specific temperatures to encourage bacterial reproduction. Once the bacteria have grown, scientists can study their characteristics, identify species, and test their responses to antibiotics. This technique is essential in fields like microbiology, medicine, and food safety, helping researchers understand bacterial behavior and develop treatments for infections caused by harmful bacteria.
