You have a few options of which the most main stream is modulation of the
bacterial population with subl lethal
doses of antibiotics, included as a component of the agar.
For example I think that if you were to examine sample X on or in an array
of agar forumulations having Chloramphenicol levels
ranging between 0 and 25 ppm in 5 ppm incriments you would defintely
observe modulation of the bacterial population. The same could be achieved
with Oxyteracycline also.
Alterantively and conversly you might try Rosebengal Chloramphenicol agar
without supplimentation with Chloramphenicol. Rose bengal itself is only a
mild retardent of bacteria growth.
One obtuse way might be to feezeshock your mixed cultures with the hope of
differentially inducing a increased lag phase in bacterial growth.
How about microfiltration at say 45 20 10 5 2 micron. That should
retain the fungal (hyphal) loading whilst gradioently allowing passage of
"most" or some proportion of the bacterial population. Recover and culture
How about calibrated centrifugation
The only other alternative I can think of is to play music in the lab which
only moulds like
I hope this helps
