Fungal (Aspergillus and Penicillium spp.) and yeast (Saccharomyces and
Candida spp.) cultures were more sensitive to cumin volatile oil and
cuminaldehyde than bacteria. Among Gram-negative bacteria, Escherichia
coli was the most sensitive to the volatile oil while Pseudomonas aer
uginosa was the most resistant. Staphylococcus aureus had an MIC almos
t double that of all other Gram-positive species tested, while the fun
gi had MIC values 10 to 20 times lower than those of the bacteria.
