“…Previous studies have demonstrated the importance of meteorological factors like wind speed, radiation, and precipitation affecting spore density in the air (Oh, 1998;Burge and Rogers, 2000;Deacon, 2006). Three meteorological variables were different between A21/M30 and A28 [max wind direction, mean cloud amount and horizontal radiation (Table 1)] and may be related to the shift from Ascomycota to Basidiomycota dominance seen in this study (Table 3).…”

Fungal spores are widespread and common in the atmosphere. In this study, we use a metagenomic approach to study the fungal diversity in six total air samples collected from April to May 2012 in Seoul, Korea. This springtime period is important in Korea because of the peak in fungal spore concentration and Asian dust storms, although the year of this study (2012) was unique in that were no major Asian dust events. Clustering sequences for operational taxonomic unit (OTU) identification recovered 1,266 unique OTUs in the combined dataset, with between 223-396 OTUs present in individual samples. OTUs from three fungal phyla were identified. For Ascomycota, Davidiella (anamorph: Cladosporium) was the most common genus in all samples, often accounting for more than 50% of all sequences in a sample. Other common Ascomycota genera identified were Alternaria, Didymella, Khuskia, Geosmitha, Penicillium, and Aspergillus. While several Basidiomycota genera were observed, Chytridiomycota OTUs were only present in one sample. Consistency was observed within sampling days, but there was a large shift in species composition from Ascomycota dominant to Basidiomycota dominant in the middle of the sampling period. This marked change may have been caused by meteorological events. A potential set of 40 allergyinducing genera were identified, accounting for a large proportion of the diversity present (22.5-77.2%). Our study identifies high fungal diversity and potentially high levels of fungal allergens in springtime air of Korea, and provides a good baseline for future comparisons with Asian dust storms.

“…An important stage in the life cycle of fungi is the spore, the dispersal agent of the organism that is either discharged into the air or becomes airborne from rain splash (Deacon, 2006). Due to this airborne stage, fungal spores are widespread and common in the atmosphere.…”

“…Conversely, the presence of microbes can be beneficial; for example, Enterococcus faecium has been found to increase fitness of pied flycatcher (Ficedula hypoleuca) nestlings [39], while Eupenicillium javanicum contains the cyclic depsipeptide, Eujavanicin A, the antifungal properties of which are effective against Aspergillus fumigates, a cause of avian aspergillois [17,40].

“…Ligninolytic enzymes are very versatile and attack a large spectrum of chemical compounds with structure similar to lignin. This property confers the ability to degrade different human made aromatic compounds, hydrocarbons, dyes with heterocycles (Balaeș et al, 2014), while in natural conditions these fungi degrade lignin and also other chemical compounds from wood (Deacon, 2006). Considering these facts, we hypothesize that the versatility of ligninolytic enzymes could also be a factor that influence the ecological adaptation in terms of colonizing very different types of wood (varied chemical composition).…”

“…Depending on their ecology and type of nutrition, these species decay the wood, decomposing cellulose, hemicelluloses and sometimes lignin, which is one of the most abundant biomacromolecule on Earth (Knežević et al, 2013). Degradation of lignin might offer fungi advantages such as eliminating the barrier for the degradation of cellulose and increasing the availability of nitrogen in a substrate with a very high C : N ratio, through degradation of other wood constituents (Deacon, 2006). This study is aimed at testing if the number of ligninases produced is influencing the spectrum of substrate / wood type / hosts, thus having ecological meanings.…”

Abstract. Lignicolous macrofungi are the most important group of wood decomposers. Among the enzymes involved in wood decomposition, ligninases play an important role in this process and species that produce those enzymes degrade both cellulose and lignin. In this study we hypothesized that ligninases are influencing the ecological success of lignicolous macrofungi. Three hypotheses have been tested: h1 -the species producing several types of ligninases have a broader spectrum of hosts / substrates; h2 -the obligate saprotrophic species have a greater potential in degrading lignin and related compounds than the other groups; and h3 -the frequencies of lignicolous species is related to the production of highly active enzymes. Scientific data compiled from literature and completed with our own experimental results have been statistically interpreted using XLStat and MaxLite Software. Our results confirm the first two hypotheses, proving that ligninases play a direct role in colonizing a wide range of wood types, with chemical particularities. The third hypothesis should be rejected as no correlation has been observed. The present study offers new insights into ecological meanings of ligninases, and is the first attempt to connect the ligninolytic enzyme system to host range.
