Resumo

This is the first report on abundance and diversity of cultured yeasts and filamentous fungi in the sediments of the Laptev and East Siberian seas. A total of 63 isolates of mycelial fungi belonging to 32 morphotypes were obtained from 35 sediment samples. Most morphotypes were represented by single colonies in individual samples; the most often occurring species were Pseudeurotium zonatum, Pseudogymnoascus pannorum, and Cordyceps farinosа. In both seas, abundance of filamentous fungi (up to 12 colonies per 1 g wet sediment) was lower than that of yeasts (up to 68 colonies per 1 g wet sediment). In the Laptev Sea, yeast abundance was low at all stations, while in the East Siberian Sea higher values were found at near-estuarine stations.

The diameter of the marks is proportional to the number of fungi in 1 g of soil at each of the stations: lighter circle - to the number of yeasts, darker - to mycelial fungi. The stations of the MSU CMI voyage - ‘station 1’ and ‘station 2’ - are also marked
