Abstract
Biodeterioration of indoor wood and microbial pollution inside buildings is one of important problem in humid areas. Number of fungi are associated with indoor wood and many of them are responsible for its deterioration by causing decay and stain. Some of them may release mycotoxins, which have hazardous impact on human health. In present study, fifteen fungi associated with wood surface were isolated and out of which genus Aspergillus dominate with four species. A. flavus was recorded from all locations. The potential of leaf extracts of nine tree species on the growth of A. flavus was evaluated by amending culture media. Considerable growth inhibition of A. flavus in the range of 1.14-45.45% was recorded on solid media and 9.37-86.66% in liquid media. Amendment of culture media @ 30% concentration of the leaf extract of Corymbia torelliana have recorded maximum growth inhibition irrespective of the media used.
