What are advantages of a solid?
The culture on solid media (agar) surface aids microbiologist in identifying microorganism because individual species often from colonies of characteristic size and appearance. When mixed population has been plated properly, it sometimes is possible to identify the desired colony based on its overall appearance and use it to obtain a pure culture. Whereas in liquid broth we get mixed culture and can not identify the seprate colony of any microbial species in that mixed culture.
