| Research Abstract |
A total of 1869 soil samples collected from 7 areas, 72 places in Xinjiang, China were used for isolation of oportunistic pathogenic fungi and mycotoxin producing fungi. The soil fungi were isolated by using the soil plate method on Czapeks agar, incubating the plates at 37 C for 10 days. The most common oportunitic pathogenic Aspergilli were Aspergillus flavus (5.1%), A. fumigatus (46.3%), A. neoellipticus (5.1%), A. niger. (19.4%), A. terreus (28.8%), Emericella spp. (25.3%), Neosartorya spp. (0.6%) and Petromyces alliaceus (3.4%). The frequencies of A. fumigatus are bight at the wasteland, steppe, field and paddy. A, niger, A. terreus and Emericella spp. Are bight at the field and paddy. Namely these Aspergilli are widely distributed in soil at dry area in Xinjiang Province. Emericella spp. Detected on 473 soil samples, 25.3% of the total samples. E. acristata, E. appenduculata, E. miyajii, E. nidulans, E. nidulans var. lata, E. qinqixianii and E. quadrilineata have been isolated from soil. E. appenduculata and E. qinqixianii have been reported as new taxon. E. appenduculata was isolated from damp grassland soil, Pamire plateau. The ascospores of E. appenduculata are characterized by ornamentation of convex surfaces which is composed of capitate swellings, and hyaline, filiform appendages. E. qinqixianii was isolated from desert soil at Taklimakan desert. The ascospores of E. qinqixianii are charactered by ornamentation of convex surfaces which is smooth, and hyaline, filiform appendages.
