ABSTRACT:
This invention relates to a transfer mechanism for microorganisms and more specifically, to a device for duplicating a growth pattern of microorganisms. The apparatus comprises a body and a transfer material on one surface of the body. The transfer material is brought into contact with a primary medium having a growth of microorganisms on the surface thereof, and transfers that growth to at least one secondary medium. The apparatus is particularly suitable for use with a hydrophobic grid membrane filter. This apparatus replaces slow and cumbersome methods for transferring microorganisms from a primary medium to a secondary medium and is an automated and efficient apparatus to effect such transfer. This device makes it now possible to transfer and duplicate the colonies of microorganisms growing on a hydrophobic grid membrane filter to fresh or different culture media.
