This thesis concern with studying the diversity of fungal growth in Jeddah city houses. About 240samples of air and dust samples from 48 houses of the four regions of Jeddah city (North, South, East and West), were collected and the isolated fungi were enumerated and identified. The highest count were in South by 1099 and North by 1053. Eleven species of fungi were identified as Black mold Alternaria alternate, A.chlamydospora, Aspergillus niger, Chatomium funicola Cladosporium herbarium, C.macrocarpum, Exophila jeanseleni, Humicola grisea, H.lanuginosa, Syncephelastrum racomosum and Ulocladium chartarium, 9 of them were toxigenic fungi. The mycotoxins production was detected using two different method (TLC and LC-ESI-MS) they produce Alternariol, Luteoskyrin, Cychlopiazonic acid, Sterigmatocystin and Rubratoxin B. Only 5 of the toxigenic fungi were selected for studying the effect of various factors on the growth and toxin production they were Alternaria chlamydospora, Aspergillus niger, Chatomium funicola, Cladosporium macrocarpum and H.lanuginosa . The effect of different media such as PDA, MEA and Wood chips on fungal growth were studied and the best medium were MEA medium. At different temptertute 25-30ºC was the best, 98-100% were the best relative humidity. Dettol was the most effective disinfected on fungal growth, followed by Clorox and Flash disinfected, while both of OXY mold , Mold Armor which made especially for mold was not effective as the other disinfected. |
