摘 要：Tianchi Volcano and Julong alkaline geothermal springs in Changbai Mountain Nature Reserve,Northeast China,are of undeniable interest for microbiological studies,due to their unique,extreme environmental *** objective of this study was to provide a comprehensive analysis of the unexplored fungal and bacterial community composition,structure and networks in Tianchi Volcano crater soils and Julong Hot Spring sediments and water,using a combination of culture-based methods and *** Tianchi Volcano crater,117 fungal strains belonging to 51 species and 31 genera were *** and Trichoderma dominated the culturable fungal community.A considerable number of isolated microbes,including filamentous fungi,such as Aureobasidium pullulans and Epicoccum nigrum,yeasts(Leucosporidium creatinivorum),and bacteria(Chryseobacterium lactis and Rhodococcus spp.),typical of high-altitude,cold,and geothermal extreme environments,provided new insights in the ecological characterization of the investigated crater,and may represent a precious source for the isolation of new bioactive *** analyses suggested that the fungal community could be more sensitive to environmental and geographical change compared to the bacterial community,whose network was characterized by more complicated and closer *** Julong geothermal springs,a total of 65 fungal and 21 bacterial strains were isolated from two analyzed pond *** genera Trichoderma and Cladosporium were dominant in sediments,while the most abundant fungi in hot spring water were Aspergillus and *** community in sediments and water was dominated by the genera Chryseobacterium and Pseudomonas,*** analysis revealed significant differences in the microorganism communities from the two hot spring *** suggested a strong influence of pH on the analyzed microbial diversity,at least when the environmental conditions became clearly alka
