The Influence of Cinnamldehyde and Citral on the Pigmentand the mRNA Expression of alb1 Gene of Aspergillus fumigatus

Abstract:

The influence of the active ingredients of citral and cinn on the pigment and the mRNA expressions of alb1 gene of Aspergillus fumigatus were studied. Results indicated that in Czapak's solid culture medium,the higher the concentration of ingredient was,the thinner the lawn would be,and the pigment became lighter and lighter gradually,even white; citral and cinn could obviously repress the expressions of alb1 gene and this effect was weakened by lower concentrations， The two can avaliably suppress the mRNA expression of alb1 gene which is essential for the biosynthesis of Aspergillus fumigatus's pigment.
