Diversity of marine culturable fungal population in mangrove wetlands of Zhanjiang

Abstract:

[Objective] The objective of this study is to define the species and distribution of the fungi in mangrove wetlands, and to lay the foundation for the development and utilization of marine fungi. [Methods] Five hundred fifty soil samples were collected from different soil types of trees (Avicennia maria, Aegiceras corniculatum, Bruguiera gymnorrhiza, Rhizophora stylosa) and tidal zone (low, middle, high). The fungal isolate was isolated by dilution plate technique from the soil samples. Fungal diversity and species identification was carried out by based on the fungal morphology and rDNA ITS analysis. [Results] A total of 274 fungal isolates were isolated from the soil samples. Among the 274 isolates, 39 fungal species in 19 genera were found. The dominant fungal genera within Zhangjiang mangrove tidal-flat area were Aspergillus, Penicillium and Trichoderma. In addition, the fungal species of Talaromyces helicus was a new record specie in China. [Conclusion] There is a wide variety of fungal species in mangrove wetlands of Zhanjiang, and with potential prospects off development and utilization.
