Antifungal Activity of Essential Oils Vapors Against Fungi Isolated from Car Air- Conditioner Filters
Abstract
Background/A car air conditioner AC filter is a suitable place for microbial growth. Fungal structures or/ and\r\ntheir by-products are pollutants of car air space. They are transmitted via air current forward passengers. Most\r\nisolates were reported as allergens and mycotoxins producers. Chemical and less nonchemical treatments\r\nwere followed to solve this problem. The current study aims to isolate and identify fungi associated with\r\nCAC filters and discuss the relationship between the fungal community with car age and the types of seat\r\ncoats. Also, we inspected the antifungal activity of the vapor and liquid phases of five essential oils in\r\nvitro. Methods/ A cross-section study was followed, a swap samples were collected during one week. They\r\nwere cultured on Sabouroad’s dextrose agar and Typha pollens agar. Plates were incubated at (25oC ±2).\r\nThe highest occurrence% were Penicillium sp. > Alternaria sp. > Aspergillus (3sp.), while Acremonium\r\nsp.,Rhizopus sp., Rodotorula sp. and Stachybotrys sp., showed low O% as well as yellow yeast and sterile\r\nmycelia. The crude oils of Hacinathus sp., Cymbopogon citratus, Myrtus communis, Eucalyptus sp.,\r\nand Cyperus rotundus were extracted and examined. ANOVA test showed that C.citratus oil vapor phase\r\nsignificantly affects the dominant isolate. Conclusion/ Car AC filter is a source of fungal structures with\r\nhealth impact. Liquid and vapor phases of EOs are probably practical alternatives to control fungal AC\r\ncontamination.\r\nKew words: Car, Antifungal, Air Conditioner Filter, Essential Oil, Vapor
