Abstract :
The Mycoflora of eight different fabrics (natural, synthetic,and blended), collected from warehouses in Jeddah, Saudi Arabia,were isolated by different methods; contact plate, dilution, Stomacher,and moisturization that followed by contact plate method. Twentythree different species were isolated. Aspergilli were the mostdominant (35%), followed by penicilli and fusaria (13% each). Thehighest fungal count (1932 CFU/cm2) was concomitant with cottonfabrics, even when blended with polyester. Wool textiles came in thesecond order of fungal counts (1421 CFU/cm2). While natural silkfibers, was less susceptible for fungal attack, polyamide textiles hadmoderate affinity toward fungal colonization.The influence of some environmental conditions (temperature,growth medium, pH and relative humidity) on the linear growth of 10representative isolates, that may have health hazards to man (Alternariaalternata, Aspergillus flavus, A. fumigatus, A. niger, Fusarium oxysporum,Geotrichum sp., Gliocladium atrum, Penicillium chrysogenum,Rhizopus nigricans and Trichoderma viride), were tested.The cellulytic and proteolytic activities of these fungi indicated that T.viride, Geotrichum sp. A. niger, A. alternata and P. chrysogenumwere with the highest activities. Antimycotic activity of twodetergents was studied and indicated that the tested fungi respondeddifferently to the detergent type and its concentration.
