It seemed that those test organisms that best survived the
artificial mixture also possessed some of the highest IC50
values eg. A. fumigatus, G. cingulata and F. culmorum.
(Table 2). The results nicely paralleled those obtained with
the M. albus cz-620 artificial test mixtures [7]. There was an
exception to this however, with P. cinnamoni having an IC50
of 0.19 and yet succumbing to the artificial mixture
(Table 1). On the other hand, the artificial mixture did kill
V. dahliae, but the fungal VOC’s had only an inhibitory
effect on this test fungus and the same phenomenon occurred
with C. coccodes (Table 2). Comparable anomalies in results
on test microbes were also observed in the past with M. albus
isolate cz-620 [7]. Most interesting, was the activity of
isolate M. albus I-41.3s against S. chartarum. This fungus is
one of the chief causes of mouldy walls, floors and other
structures in poorly ventilated structures and this finding
suggests the possibility of using M. albus or its products for
industrial use.
