Öğe Airborne fungi and actinomycetes concentrations in the air of Eskisehir city (Turkey)(Sage Publications Ltd, 2004) Asan, A; Ilhan, S; Sen, B; Erkara, IP; Filik, C; Cabuk, A; Demirel, RThe present study investigated the isolation and identification of airborne fungi from three different urban stations located in Eskisehir (Turkey). Air samples were taken by exposing a Petri dish with Rose-Bengal streptomycin agar medium for 15 min and after incubation the number of growing colonies was counted. The sampling procedure for fungi was performed 35 times at the research stations weekly between March and November 2001. A total of 2518 fungal and 465 actinomycetes colonies were counted on 420 Petri plates over a nine-month period. In total, some 20 mould species belonging to 12 genera were isolated. Alternaria alternata, Cladosporium cladosporioides and Scopulariopsis brevicaulis were the most abundant species in the study area (13.66, 5.80 and 5.50% of the total, respectively). Relationships between fungal spore numbers, aerosol air pollutants (that is the particulate matter in the air) and sulphur dioxide together with the meteorological conditions were examined using statistical analysis. Number of fungi and actinomycetes were tested by multivariate analysis (MANOVA) according to the areas and months. Fungal numbers were nonsignificant according to the areas and months (p > 0.05), but the number of actinomycetes recorded was significant (p < 0.01).Öğe Airborne fungi in urban air of Edirne city (Turkey)(Versita, 2002) Asan, A; Sen, B; Sarica, SThis paper provides the isolation and identification of airborne fungi from 6 different urban stations located in Edirne (Turkey). Samples were taken from air by exposing a Petri dish with Rose Bengal streptomycin agar medium for 15 minutes and then growing colonies were enumerated. Sampling procedure for fungi was performed 12 times in research stations monthly between September 1999 - August 2000. A total of 2481 fungal colonies were counted on 216 Petri plates in a year. As a result, 37 mould species belonging to 11 genera have been isolated. Of these, 5 species belonging to the Aspergillus and Penicillium genera are new records for Turkey. Alternaria citri and Penicillium asperosporum were the most abundant species in the study area. The relationships among fungal spore numbers, air pollutants [aerosols (it means particulate matter in air) and SO(2)] and meteorological factors were examined using statistical analysis. Relation between concentrations of SO(2) and colony numbers (r = -0.687) and, relation between temperature and colony numbers (r = 0.591) are significant statistically at 0.05 level according to Spearman Correlation Calculation (Non-linear).Öğe Aspergillus, Penicillium and related species reported from Turkey(Mycotaxon Ltd, 2004) Asan, AThis database, available online, reviews 250 published accounts and presents a list of species representing the genera Aspergillus, Penicillium and related species in Turkey. Aspergillus niger, A. flavus, A. fumigatus, A. versicolor and Penicillium chrysogenum are the most common species in Turkey respectively. According to the published records, 365 species have been recorded from various subtrates in Turkey.Öğe Indoor airborne fungal spores and home characteristics in asthmatic children from Edirne region of Turkey(Mosby, Inc, 2002) Yazicioglu, M; Asan, A; Önes, Ü; Vatansever, U; Sen, B; Ture, M; Bostancioglu, M[Abstract Not Available]Öğe Isolation, identification and seasonal distrubution of airborne and waterborne fungi in Terkos Lake (Istanbul-Turkey)(Wiley-V C H Verlag Gmbh, 2003) Asan, A; Kirgiz, T; Sen, B; Camur-Elipek, B; Guner, U; Guher, HThis paper focuses on isolation and identification of airborne and waterborne fungi from different parts of Terkos Lake located in Istanbul (Turkey). The quantitative and qualitative fungal composition of the air and water of the Lake was surveyed monthly for a year (August 2000-July 2001). Water samples were taken at five different stations at Terkos Lake. Airborne fungal spore levels were estimated by exposing a petri dish containing Rose-Bengal streptomycin agar medium to air for 15 minutes. A total of 2372 fungal colonies (1032 from air and 1340 water) was counted on 216 petri plates. We isolated twenty mould species belonging to 9 genera. Scopulariopsis brevicaulis, Penicillium expansum and Cladosporium herbarum were the most abundant species (22.0%, 13.4% and 12.9%, respectively). Cladosporium herbarum and sphaerospermum are very common in air samples (29.7% and 27.0%, respectively). Many of the species isolated are rarely in the atmospheric and water environment such as Aspergillus niger and Cladosporium variabile. Statistical analysis revealed a positive correlation between total CFUs and a number of environmental factors.Öğe Microfungi in cultivated fields in Eskisehir Province (Turkey)(Wiley, 2005) Demirel, R; Ilhan, S; Asan, A; Kinaci, E; Oner, SThe soil microfungi flora was investigated in four locations of Eskisehir (Turkey). 56 soil samples were seasonaly collected from 14 stations in the areas of Karacahoyuk, Bahcecik, OGU I, and OGU II. A total of 110 species belonging to 32 genera were encountered including Absidia, Acremonium, Alternaria, Aspergillus, Beauveria, Botryoderma, Chaetomium, Chrysosporium, Cladosporium, Eupenicillium, Eurotium, Fusarium, Geotrichum, Gliocladium, Gonytrichum, Metarrhizium, Mucor, Myrothecium, Paecilomyces, Penicillium, Phoma, Plectosphaerella, Rhizoctania, Rhizopus, Scopulariopsis, Septonema, Stachybotrys, Trichocladium, Trichoderma, Ulocladium, Verticillium, and Wardomyces. Twenty five species were more frequent (all locations) while twenty seven species were rare (only one sample). Mainly, Acremonium kiliense, Aspergillus ochraceus, A. terricola var. americanus, A. versicolor, Cladosporium cladosporioides, Fusarium oxysporum, F. solani, Gliocladium roseum, Penicillium chrysogenum, P. corylophum, P. expansum, P. griseofulvum, P. implicatum, P. restrictum, and Stachybotrys chartarum were the most common and abundant microfungi in all locations. Five species Aspergillus subsessilis, A. terreus var. africanus, Eupenicillium egyptiacum, Paecilomyces ramosus, and Penicillium novae-zeelandiae are likely to be newly recorded for Turkey. The microfungi number in Eskisehir soils was between 25 000-234 000 CFU/g (mean value at 126 375 CFU/g).Öğe Monitoring indoor airborne fungi and bacteria in the different areas of Trakya University Hospital, Edirne, Turkey(Sage Publications Ltd, 2002) Sarica, S; Asan, A; Otkun, MT; Ture, MThe aim of this investigation was to monitor monthly the densities and distribution of indoor airborne fungi and bacteria in 6 different areas of Trakya University Hospital (Edirne, Turkey). Areas monitored were an operating theatre, birthing-room, emergency department, service area for infectious diseases, intensive care unit and the canteen. Our method was to expose Petri dishes which contained rose-bengal streptomycin agar and 5% sheep-blood agar media to room air for 10-min periods. Samples were collected at 1-month intervals from September 2000 to February 2001. A total of 156 microfungal and 535 bacterial colonies were counted on 144 plates. During a 6-month period, 10 bacterial genera (Acinetobacter, Bacillus, Corynebacterium, Enterococcus, Escherichia, Listeria, Micrococcus, Propionibacteria, Staphylococcus and Streptococcus)7 fungal genera (Altemaria, Aspergillus, Cladosporium, Paecilomyces, Penicillium, Scopulariopsis and Trichothecium) and 33 fungal species were isolated from the hospital air. Penicillium loliense, P. melinii and P. phoeniceum were newly recognised species for Turkey. Some bacterial species such as coagulase-negative Staphylococcus, Micrococcus and Corynebacterium spp. were predominant (percentages of colonies counted were 72.2, 10.7 and 8.8%, respectively). Cladosporium and Penicillium were the most prevalent fungal genera. Cladosporium was predominant in September, November and February, Alternaria in October and December and Penicillium in January. Staphylococcus spp. was the most common bacterial species in all months. Statistical analyses (regression with optimal scaling test) were applied to the data.Öğe Monitoring of fungi and bacteria in the indoor air of primary schools in Edirne city, Turkey(Sage Publications Ltd, 2005) Aydogdu, H; Asan, A; Otkun, MT; Ture, MWe monitored levels of bacteria and fungi in the indoor air at selected sites of several public primary schools in the city of Edirne, Turkey. Sampling was by the Petri plate method onto both a Rose-Bengal streptomycin agar medium and a 5% sheep-blood agar medium exposed to the air for 10-minute periods. Samples were collected monthly over a period of 6 months between August 2001 and January 2002. A total of 941 microfungi and 2066 bacterial colonies were counted on 90 Petri plates. During this 6-month period, 19 bacterial genera, 15 fungal genera and 48 species of fungi were isolated from the air in the schools. Some bacteria, such as coagulase-negative Staphylococcus, Corynebacterium and Bacillus, were predominant (42.7%, 20.4% and 6.9% of the total, respectively). Penicillium, Cladosporium and Alternaria were the most common fungal genera (42.8%, 19.3% and 10.1% of the total, respectively). Staphylococcus, Acinetobacter, Corynebacterium, Propionibacterium and Pseudo-monas genera were found in every month. Statistical analysis of the data showed a positive correlation between the concentrations of bacteria and air humidity (p = 0.002, R-2 = 0.726) and between bacterial concentrations and age of the schools (p=0.045, R-2 = 0.787). Also, that there was seasonal variation since the concentrations of fungi and bacteria varied according to the months (p = 0.001).Öğe Soilborne fungi in wheat fields of Kirka Vicinity (Eskisehir-Turkey)(Versita, 2001) Ilhan, S; Asan, AThe quantity, quality, the seasonal and ecologic variation of microfungi in the soil samples collected with the Brown's technique from the five wheat fields of Kirka Vicinity, Eskisehir between August 1995 and May 1996 were studied. The dilution plate technique was used for isolation of microfungi. The number of microfungi ranged from 20.000 to 275.000 CFU. A total of 11 genera (Alternaria, Aspergillus, Cladosporium, Gliocladium, Microdochium, Papularia, Penicillium, Rhizopus, Talaromyces, Trichoderma, Verticillium) and 28 species (Alternaria alternata, A. radicina, Aspergillus flavipes, A. ficuum, A. fumigatus, A. niveus, A. nutans, A. parvulus, A. terricola, A. wentii, Cladosporium herbarum, Gliocladium roseum, Microdochium nivale, Penicillium adametzii, P. allahabadense, P. citrinum, P. commune, P. crateriforme, P. decumbens, P. estinogenum, P. lanosum, P. olsonii, P. paneum, P. piceum, P. restrictum, P. rugulosum, P. velutinum, Talaromyces wortmannii) were determined. G. roseum and A. wentii were found as the most common species and both were detected in 5 separate stations. The probability of being new for Turkish soil mycobiota is considerably high for A. nutans, P. allahabadense, P. crateriforme and P. paneum species.
