“…One of the possible explanations for this finding could be related to reduced ventilation in swine houses during winter to avoid heat loss resulted in increased concentrations of airborne particulates1617, which could lead to increase in fungal abundance during winter. Indoor air fungal concentration was shown to increase with PMs concentrations18. This explanation is also supported by the results of correlation analysis, which indicate a negative correlation between fungal abundance and temperature, and airspeed (Table 2), whereas CO 2 , NH 3 , and PM2.5 showed positive correlation with fungal abundance (Table 2).…”

We examined the abundance, diversity and community composition of airborne fungi in swine houses during winter and summer seasons by using quantitative PCR and Illumina HiSeq sequencing of ITS1 region. The abundance of airborne fungi varied significantly only between seasons, while fungal diversity varied significantly both within and between seasons, with both abundance and diversity peaked in winter. The fungal OTU composition was largely structured by the swine house unit and season as well as by their interactions. Of the measured microclimate variables, relative humidity, particulate matters (PMs), ammonia, and stocking density were significantly correlated with fungal OTU composition. The variation in beta diversity was higher within swine houses during summer, which indicates that the airborne fungal community composition was more heterogeneous in summer compared to winter. We also identified several potential allergen/pathogen related fungal genera in swine houses. The total relative abundance of potential allergen/pathogen related fungal genera varied between swine houses in both seasons, and showed positive correlation with PM2.5. Overall, our findings show that the abundance, diversity and composition of airborne fungi are highly variable in swine houses and to a large extent structured by indoor microclimate variables of swine houses.

“…Later, several investigations were conducted on airborne fungi in different cities and seasons. In most studies only the fungal propagules were quantified and if identification was performed, then it was based on morphology (Wu et al., 2000, Li et al., 2006, Si et al., 2007, Liu et al., 2014).

“…However, most surveys focused on total fungal counts and identified fungi to genera or species level based on phenotypic characters (Wu et al., 1982, Wu et al., 2000, Fang et al., 2005, Li et al., 2006, Si et al., 2007, Liu et al., 2014). Molecular based identifications are occasionally being performed and Luo et al.…”

Talaromyces contains both asexual and sexually reproducing species. This genus is divided in seven sections and currently has 105 accepted species. In this study we investigated the Talaromyces isolates that were obtained during a study of indoor air collected in Beijing, China. These indoor Talaromyces strains are resolved in four sections, seven of them are identified as T. islandicus, T. aurantiacus, T. siamensis and T. albobiverticillius according to BenA sequences, while 14 isolates have divergent sequences and are described here as nine new species. The new species are placed in four sections, namely sections Helici, Islandici, Talaromyces and Trachyspermi. They are described based on sequence data (ITS, BenA, CaM and RPB2) in combination with phenotypic and extrolite characters. Morphological descriptions and notes for distinguishing similar species are provided for each new species. The recently described T. rubrifaciens is synonymised with T. albobiverticillius based on presented phylogenetic results.

“…Davis drew on the related content of self-efficacy theory and the cost-benefit paradigm based on the theory of planned behavior and took "residents think that the use of new technology will make their lives and work better to a large extent" and "the trade-off of the difficulty level in using this technology on the basis of perceived benefits" into consideration in the study of the residents' technology acceptance. They used Perceived Usefulness and Perceived Ease of Use as its measuring indicators and put forward a TAM on this basis [31,32]. The model was originally used to find the reasons why computers were widely accepted.…”

Abstract:In order to explore the influence mechanism of traditional Chinese culture values on urban residents' acceptance of the reuse of recycled water, this paper selects interdependent self-constructional indicators representing the dependency relation between people as the representative of traditional culture values. In this paper, interdependent self-constructional indicators are introduced based on a technology acceptance model (TAM), in order to establish a hypothesis model. Following this, the writer conducts a study that shows the influence on the acceptance of recycled water through the formation of interdependent self-construction. Finally, the influence mechanism of traditional cultural values on citizens' behavior regarding the reuse of recycled water is determined. To start with, the writer verifies the reliability and validity of data from 584 samples, and then tests the goodness-of-fit between the sample data and the hypothesis model by AMOS21.0 (software). On this basis, the writer analyzes the direct and indirect influence through the hypothesis model and finds that the interdependent self-constructional intensity will accelerate the acceptance process of recycled water technology by positively influencing a change in the residents' attitudes to recycled water. The conclusion shows that traditional Chinese cultural values have a certain influence on urban residents' acceptance of the reuse of recycled water. Meanwhile, the writer clarifies the influence's mechanism.
