This is the PDA patch plate I made, and where I isolated my only producer. The other producers I have were generously given to me by Elizabeth Altman.

this is an image of my producer. It appears to have both a mix of both gram + and gram – bacilli.  I’m not sure how to characterize this, it could be a mixed culture.

Both isolates from Elizabeth looked very similar.  They show individual gram positive bacilli on the left, and filamentous “clusters” of cells on the right.
