| 中文摘要: |
| 家庭毛巾是日常生活中使用频率最高的的棉纺织品之一，但是霉菌污染严重影响毛巾的使用及威胁人类健康。为了解家庭毛巾真菌群落的组成，采用高通量测序分析了中国七大地区家庭毛巾表面真菌群落组成、结构及其影响因素。结果表明，家庭毛巾表面真菌群落分属5门、18纲、47目、111科、177属和256种，其中优势菌门为子囊菌门（Ascomycota）和担子菌门（Basidiomycota），优势菌属为曲霉属（ Aspergillus）、枝孢属（Cladosporium）、葡萄穗霉属（Stachybotrys）。 PCoA和PerMANOVA分析均表明沿海和内陆环境对家庭毛巾真菌群落结构具有较大的影响，内陆样本（IA）α-多样性指数的平均值均高于沿海样本（CA）。dbRDA分析表明 Aspergillus、Cladosporium、Chaetomium 等真菌的相对丰度与当地的温度和湿度呈正相关，同时这些高丰度真菌在毛巾表面真菌群落的稳定性上起着重要作用。FunGuild功能预测表明，家庭毛巾表面真菌群落主要为腐生营养型。该研究为家庭毛巾中真菌的防控提供了参考。 |
| 英文摘要: |
| Household towels are one of the most frequently used cotton textiles in daily life, but mold contamination can seriously affect their use and pose a threat to human health. To understand the fungal community composition of household towels, this study utilized high-throughput sequencing to analyze the fungal community composition, structure, and influencing factors on the surface of household towels from seven major regions in China. The results showed that the fungal communities on the surface of household towels belonged to 5 phyla, 18 classes, 47 orders, 111 families, 177 genera, and 256 species. The dominant phyla were Ascomycota and Basidiomycota, while the dominant genera included Aspergillus, Cladosporium, and Stachybotrys. Both PCoA and PerMANOVA analyses indicated that coastal and inland environments significantly influenced the fungal community structure of household towels. Additionally, the average α-diversity index of inland samples (IA) was higher than that of coastal samples (CA). The dbRDA analysis indicated that the relative abundance of fungi such as Aspergillus, Cladosporium, and Chaetomium was positively correlated with local temperature and humidity. Moreover, these high-abundance fungi played a crucial role in maintaining the stability of the fungal communities on towel surfaces. FunGuild functional prediction indicated that the trophic composition of fungal communities on household towel surfaces was saprotroph. This study provides a theoretical basis for the prevention and control of fungal contamination in household towels. |
