Study of Aeromycoflora in the Indoor Environment of College Library

Few studies have focused on the aeromycoflora of the indoor environment, despite the fact that certain airborne microorganisms in the indoor atmosphere are responsible for the biodeterioration of library materials. The fungi found in the library's ancient books and paper materials and how they contribute to deterioration. The bio - deterioration includes decolorization of the books as well as mildewing of the substrate, which is the true manifestation of the interaction between organism and material,according to Tilak et al. (1989). Old books with bindery glues and wooden partitions also support the growth of fungi in the favorable condition. The purpose of the present aero mycological investigation was to better understand the library's indoor aeromycoflora. Any learning institution's primary information and knowledge resource center is the library. According to( Sahare N.H. and Chinchkhede -2017), polysaccharides from green plants that yield fibers that are suitable for papermaking, glue, gum in bonded quantities, and occasionally leather can be utilized as a binding material can all contribute to bio degradation in the materials held in libraries. Students, teachers, and other stakeholders use these paper resources in the form of books, newspapers, and journals. The majority of their time was spent handling books by library workers. The primary challenge facing librarians is to preserve these materials in meticulous and protective ways for many years. Recently, it was thought that artificial climate control was the only way that would maintain the right temperature and humidity conditions. Natural ventilation often proves to be the most suitable choice, especially in libraries where maintaining an air conditioning system would be challenging and it would operate intermittently. Good air circulation, however, may allow more effective moisture exchange between objects and the air (Saoji A.A. and Giri S.K. 1997). According to research on Aeromycoflora in libraries undertaken by J. S. Ambhore and V. P. Mali in 2007, in in addition to damaging the books, it may also induce allergy disorders in library visitors as well as staff members who spend the majority of their time therein. (Bhagat G.S., Ambhore J.S., Mali V.P., Ambhore J.S., and B. N. Pande 2015) papers can lead to respiratory and cardiac issues as well as allergic reactions in both staff members and visitors. The aeromycoflora of the Library's indoor environment have been identified during the current research effort. This library's aeromycoflora was reviewed. The primary objective of this study was to identify the aeromycoflora, their concentration, and diversity in the working library's indoor environment. According to V. J. Ambhore et.al.( 2020.) ( Kalbende., Dalal L., Bhowal (2012). investigation, the library's indoor environment contained isolated aeromycoflora, some of which were found to be responsible for the deterioration of books preserved there and for contributing to respiratory disorders, allergic diseases, and asthma in readers and visitors. The prevalence of aeromycoflora indoors may be a result of conducive environments (such as cluttered bookcases and old newspapers) for fungal development.

The result of aeromycological survey conducted in the Govt. B.Ed. College library, shows that library is full with aeromycoflora in indoor environment. A total of 13 types of fungal colonies were identified from indoor environment of the library, with single sterile hyphae and rest 12 spore types (table 1).According to their occurrence in the exposed petriplate samples, the highest population in terms of percentage occurrence were of Aspergillus niger -10.86and Alternata alternaria and Rhizopus sp.(outdoor 16%) and Aspergillus flavus Candida sp. and Rhizopus sp (indoor-14.28 % and outdoor-66%). From Govt. B.Ed. College library total 12 fungi were isolated out of which 11 were spore types and one was sterile hyphae. Highest population among the exposed petriplate samples were of Curvularia-11.4% Aspergillus-10.86%, Didymosphaeria-10.86%, Alternaria.-10.32%, Cladosporium.- 9.78%, Botryosphaeria.- 8.69%,Rhizopus-8.69%,Helminthosporium- 6.52%, Cercospora -5.43%. Penicillium 4.89%, Bispora-3.26%, Nigrospora-3.26%. Among all the fungal spore types. The taxonomic group Deuteromycotina showed dominance in the total spore contribution. Vacuum cleaners and antimicrobial properties. Materials needed to be used. This will help in reducing the level of dust and aero spores.

Resulting from this investigation aeromycoflora indoors from libraries has been li nked to allergy and airborne disorders, as well as the destruction of both cellulosic and no n-cellulosic materials found there. The current study shows that the library's indoor atmos phere contains a variety of mycoflora. Further research based on atmospheric parameters may yield information that will help us better comprehend the relationship between abioti c and biotic processes. Concern has also been raised about the impact of airborne fungus spores on human health, which might be investigated using the preliminary information i n this research paper. Students and others who are exposed to indoor airborne inhalant m ould allergens may experience respiratory symptoms, airway diseases, and allergies.
