Abstract
AbstractStudies on the diversity, distribution and ecological role ofSaprolegniales(Oomycota) in freshwater ecosystems are currently receiving attention due to a greater understanding of their role in carbon cycling in various aquatic ecosystems. In this study, we characterized severalSaprolegnialesspecies isolated from Anzali lagoon, Gilan province, Iran, using morphological and molecular methods. Four species ofSaprolegniawere identified, includingS. anisosporaandS. diclinaas first reports for Iran. Evaluation of the ligno-, cellulo- and chitinolytic activities were also measured using plate assay methods. Most of theSaprolegnialesisolates were obtained in autumn and nearly 50% of the strains showed chitinolytic and cellulolytic activities. However, only a fewSaprolegnialesstrains showed lignolytic activities. This study has important implications for better understanding the ecological niche of oomycetes, and to differentiate them from morphologically similar but functional different aquatic fungi in freshwater ecosystems.
