We aimed at the systematic evaluation of air-borne fungal flora of the National Library, Kolkata for a period of three months beginning from February to April, 2010 to determine their identification, concentration and diversity in both indoor and outdoor environment to understand the cumulative aeromycoflora composition. The period of study was the post winter period followed by pre-summer months that was mild to moderate warm and low to high humid condition with temperature and humidity ranges of 17.0-38.2°C and 26-92% respectively. Air sample was collected with interval of two weeks by means of gravitational settling method using petri dishes with Malt Extract Agar (MEA) media. Fungal colonies that formed after 3-5 days incubation period at 25-28°C were identified on the basis of micro and macro morphological characteristics and finally percentage contributions of individual fungal species were calculated. A total of 21 types of fungal spores were identified from indoor environmen...

A relative study of aeromycoflora in Pt. Sundar Lal Sharma Library in Pt. Ravishankar Shukla University(C.G.) was studied during 2014-15. In the present disquisition period it was observed that fungal population varied from season to season and month to month. Environmental factor plays an important part for the distribution of the fungal spores. The fungal population isn't homogenous throughout the time and shows seasonal variation. The present work was grounded on the collection of fungal spores from the atmospheric air from the spore trapper technique, potato dextrose agar media was used for the culture of fungal spores. The disquisition showed variation in number as well as in composition of fungal species of these areas. It was observed that maximum fungal population was observed in winter season, due to favorable temperature and relative moisture, moderate in rainy season and minimal number of fungal populations was recorded in summer season, conceivably due to inimical temperature and relative moisture for mycoflora.

Fungi are heterotrophic eukaryotes that are usually filamentous, devoid of chlorophyll and chitinous cell wall, and produces spores. They are found in the soil, water, air, on vegetation, on humans, and everywhere in the environment. Many species of Fungi are present in the air and results in allergy reactions which is technically called as Aeroallergens. Fungal density in the air varies in accordance with geographical regions and seasons. Besides, climatic parameters such as wind, humidity, temperature, precipitation, altitude, and flora combination may also affect the type and amount of fungi in the air. In the present study, the prevalence of industrially beneficial fungal population in Sacred Heart College campus was studied. The prevalence of industrially beneficial fungi (Aspergillus niger and Penicillium chrysogenum) was high in the month of June 2017, August 2017, and November 2017, and low in July 2017, September 2017, and October 2017. It was observed that the growth and prevalence of A. niger was very high in Sacred Heart College campus when compared to P. chrysogenum.

Observation on the Fungal airspora of some indoor & outdoor environments of Indira Gandhi medical College & Hospital, Nagpur were carried out from January 2008 to December 2009, using Petridish exposure method. A total of 18 fungal spores were recorded during the study period. Some of the dominant fungal forms encountered w.ere Cladosporium, Aspergilli, Peniciillium, Alternaria, Curvularia. etc. Impact of airospores on human allergic disorders is discussed

In an average, 2106 fungal colony forming units were settled within ten minutes on one square meter area at noon from the air of Dhaka University campus during February 2011 to January 2012. Among the identified fungi, Aspergillus was one of the most dominating genus in all the stations over the study period. The second was Penicillium followed by Cladopsorium, Curvularia, Alternaria, Fusarium, Trichoderma, Pestalotia, Rhizopus and Colletotrichum. In the dry winter (December - February), Alternaria, Cladosporium, Curvularia and Rhizopus showed its peak. Hot humid summer (April) is the most favourable season for the occurrence of Colletotrichum. Similarity has been found in fungal biodiversity in the indoor and outdoor air. However, higher number of colony was recorded from indoor (57.23%) than that of outdoor air. DOI: http://dx.doi.org/10.3329/bjb.v42i2.18029 Bangladesh J. Bot. 42(2): 273-278, 2013 (December)

Fungi constitute a major part of air flora along with bacteria, algal spores, filaments, pollen grain etc. The air borne fungal spores cause serious health problem like allergy, asthma, skin diseases etc. Large number of fungal spores presents indoor environments like houses, hospitals, colleges, schools as well as public places like library environment because they growing on books and causes air pollution and health problems. The present investigation describes a qualitative and qualitative assessment in indoor environment of library of Govt. E. Raghvendra Rao P.G. Science College, Bilaspur (C.G.). A total of 25 types of fungal colonies were identified from pre- exposed Petri plates. Aspergillus niger, Aspergillus flavus, Mucor sps., Cladosporium cladospriodes, Alternaria alternata, Fusarium oxysporum, Penicillium crysogenum, Rhizopus nigricans were dominant fungal species isolated from old book section and Aspergillus niger, Alternaria alternata, Aspergillus flavus, Mucor sps., cladosporium herbarium. Fusarium oxysporum, Cladosporium cladospuriodes and Ttrichoderma viridae were dominant fungal species isolated from new book section.

Airborne fungal spores constitute one of the important components of microbial population of ambient air. Aeromycological study was conducted for two years (January, 2012 to December, 2013) using Rotorod air sampler in the indoor air of certain residential dwellings in Thanjavur District, Tamil Nadu, India. During the present investigation, 15 fungal types were detected of which Trichoderma spores contributed highest concentration. Maximum concentration of fungal spores was observed in the month of August in 2012 and November in 2013 while minimum concentration was observed in the month of September in both years. Allergenically significant fungal spores responsible for serious health hazards were detected throughout the investigation period. Seasonal variation of airborne fungal spores was correlated with meteorological parameters.

Aeromycoflora over slum area at Raipur (Kukurbeda) was earned out from June 2004 to December 2004 with the help of gravity petriplates method. During present investigation 435 colonies of 28 fungal species were identified. Maximum 17 species fungal species were observed in the month of November while minimum 10 fungal species were observed in August. Out of total fungal flora, the percentage contributions of different classes were as follows, Zygomycotina (7 .14% ). Deuteromycotina (67.85%), unidentified groups (21.42%) and Mycelia sterilia (3.57%). Out of total fungal population Aspergillus niger (12.87%) was most dominated whereas; Curvularia sp. (11.72%), Cladosporium sp. (9.88%), Altemaria sp. (9.19%) and Penicillium sp. (6.66%) were codominant fungal spores. Keywords : Aeromycoflora, Dominant, Slum area.

Air borne fungi of Hill fort region of Channagiri is studied with help of Petriplate exposure method using Pottato dextrose agar media, petriplate exposure time is 15min. Sampling is taken in the month of January 2013 total 74 fungal colonies represented 07 fungal types were observed during the present investigation period. Environmental condition plays an importance role in the distribution of the fungal spores. Out of 07 fungal species most numbers of fungi are anamorphic groups. The fungal species were Aspergillus, Pencillium, Curvilaria, Cladosporium, Fusarium Rhizopus, Alternaria species were identified. Aspergillus species (47.2%) showing maximum contribution is observed where as Rhizopus shows minimum contribution.DOI: http://dx.doi.org/10.3126/ijasbt.v1i2.8203 Int J Appl Sci Biotechnol, Vol. 1(2): 60-62
