ECOLOGICAL STUDIES ON TILE SYMBIOSIS OF TER ITOMYCES ...

slight controlling Offect on the
_Paecil2Mces; variotii*
growth of Cephalos]22rium, and
Cellophanes novoblocin and the fungicides slightly Increased
the growth of Termit2=ces, and prevented or greatly reduced the
growth of Penicillium sp,, A. niger and prevented germination of
their spores. The growth of sterile imycelium was slightly reduced$
but there was no effect on Cephalosl! 2rium.
Ox bile inhibited the growth of P. variotii, A. nin and
Penicillium spog but also reduced the growth of TermitpmXSexp Gallic
acid slightly reduced the growth of CepjMlosg2rium.
The most suitable medium at this stage would appear to be that
containing the fungicides Benlatel Murphy and Itarathanal plus ox bilet

Concluaions
Substances a2l! earing to be unsultablo
Substances rejected due to their non-inhibitory effect on the
growth of the contaminating fungi and non-stimulatory effect on
