(1) Substances rejected for use In the nelective medium
The substances which allowed no (Table 3*1,, _2) or very reduced
(under 50% of control growth
(Table 3-1-3) wero rejected. These were
Dithane, Karathane (at 0,, 0201-1)9 nystatin, OPP,, tannic acIdj
salic7ylanilides sorbic acid* P*L)oA*t Richards arjar and Oatmeal agar.
Zoberi (1979) vas unable to get. (; rowth of mycotCtes on P*D*A* but
13atra and Batra (1979) obtained growth from mycotates of Termitgamces
albuminopus on it. Batra and Batra (1966) isolated Termitamycen-on
PDA but with the addition of 10 gl-l of yeast extract which presumably
supplied the Ingredients missing from PDA necessary for the growth of
Termito=cene Although cycloheximide allowed the growth of
Ancistrotermen cavithorax and Hicrotermes associated cultures at
0.003 01-1 (Table 3-1-3). the culture from Microternes was reduced
bY 34%. It also affected the form of growth of Tormit=ce-9 and so
was rejected* Sabourauds agarp Czapek agar and Cornmeal agar were
not tested further as a great deal of contamination occurred an tlie
plates*
(1-7) Substances selected for further testing
Sub: 3tances which did noteffect the form of growth of Ter-mitomyces
(those mariced ' in Table 3,1,3) were tested further to assess their
effect on cont=inating fungi.
