Localization of protein secretion in fungal colonies using a novel culturing technique; the ring-plate system.

ABSTRACT

A novel culturing technique, called the ring-plate system, is described. Fungal colonies are grown on a polycarbonate membrane placed on a plate with 6 ring-shaped wells that are filled with liquid medium. This culturing technique enables simultaneous monitoring of environmental conditions and secretion in different parts of the fungal colony.
