The inhibition of mycelium growth in a Zygorhynchus sp. and an Aspergi
llus niger isolates was studied, The inhibition rates (IR) caused by 4
essential oils (EO), 5 fatty acids and sodium chloride at various con
centrations were determined in Sabouraud Dextrose Agar. A synergy of a
ction was observed between sodium chloride at 7.5% and the EO of thyme
(0.04%), camomile (0.4%) and mugwort (0.2 and 0.1%) on A. niger and b
etween sodium chloride (5%) and the EO of camomile (0.1%) and mugwort
(0.1 and 0.01%) and sodium chloride (7.5%) and eucalyptus EO (0.4 and
0.2%) on Zygorhynchus sp. Camomile EO (0.13%) associated with propioni
c acid (0.075%), lauric acid (0.05%) or oleic acid (0.15%) led to syne
rgetic effect on Zygorhynchus sp. as well as thyme EO (0.04 and 0.05%,
respectively) with propionic acid (0.1%) and linolenic acid (0.075%)
on A. niger. Other combinations exerted no higher effects than each of
the substances used alone. Practical applications of the results obse
rved were discussed.
