secrete a versatile armory of antimicrobial
molecules that exert a wide range of antimicrobial activities
against Gram-negative and -positive bacteria. The present
study was concerned with the antimicrobial activity of benzaldehyde
identified from P. temperata M1021. The antimicrobial
activities of benzaldehyde were evaluated against
bacteria and fungi. The potency was assessed by the percent
inhibition of bacterial and fungal growth in comparison with
control. Zero concentration was considered as a negative
control. Generally, benzaldehyde killed 72‒80% at the minimum
inhibitory concentration (MIC), but the inhibitory effect
varied according to the type of tested microorganism
(Table 2).
