Two identical DNA sequences from guano heaps in two of the caves with recent bat droppings were retrieved. These sequences were closely related to several unidentified Geomyces clones and to pathogenic G. destructans, but definitive identification remained elusive. Despite the presence of Geomyces species, thus far there has been no report of Whitenose syndrome (WNS) symptoms in bats in Slovenia. Overall physical and chemical conditions in guano, particularly in large guano heaps, offer a suitable environment which might serve as a reservoir for pathogenic Geomyces strains and could represent a permanent reservoir for in situ infection of bats. Screening of guano and analysis of more data related to guano ecology could lend clues to control WNS outbreaks and mortality linked to G. destructans.展开更多

The results revealed that G. luteus fermentation could significantly improve the antioxidant activity and total phenolic content of S. miltiorrhiza. The main antioxidant constituents were characterized by spec- troscopic analysis as salvianolic acids. High-performance liquid chromatography (HPLC) quantification also showed the enhanced content of salvianolic acid B after fermentation. The present study suggests that G. luteus fermentations are effective in the S. miltiorrhiza salvianolic acids' enrichment process.展开更多
