The proper term for the type of medium used in this scenario is selective medium. Selective medium is designed to select for the growth of specific organisms while inhibiting the growth of others. In this case, the Lowenstein-Jensen medium is designed to selectively allow the growth of Mycobacterium species while suppressing unwanted background organisms. It is not a differential medium since it does not differentiate between different types of organisms based on their characteristics.
