  1. Minimum inhibitory concentrations (MIC) of fruit body extracts against bacteria (Bacillus subtilis and Staphylococcus aureus), a selection of filamentous fungi, and the yeast Candida kruseii (C. kru.) (Ī¼gĀ mLāˆ’1). Minimum bactericial concentrations (MBC) are provided for bacteria. Minus (āˆ’): no inhibition observed using the highest test concentration of 1000Ā Ī¼gĀ mLāˆ’1; asterisks (*): the inhibitory effect was confirmed by 3 replicates; x: alterations in growth morphology (branching); n.t.: not tested. The results for the two gram-negative bacteria tested (E. coli, P. aeruginosa) are not shown in the table, because none of the tested extracts showed an inhibitory effect atā€‰ā‰¤ā€‰1000Ā Ī¼gĀ mLāˆ’1. For Trichophyton sp., already the solvent showed an inhibitory effect at a concentration of 4.8 % EtOH. A. flav. = Aspergillus flavus, A. fum. = Aspergillus fumigatus, A. orc. = Absidia orchidis.
