Abstract

Three new compounds including one furanone, one morpholinone and one tetrahydrofuran together with three known compounds were isolated from the broth extract of the marine-derived fungus Talaromyces sp. PSU-MF07. The structures of the isolated compounds were determined on the basis of spectroscopic methods. The relative configuration was assigned using NOEDIFF data whereas the absolute configurations were established by Mosher’s method, specific rotations and electronic circular dichroism (ECD) data. Some isolated compounds were tested for antimicrobial activity. Only known penioxalicin exhibited weak antibacterial activity against methicillin-resistant Staphylococcus aureus SK1 with an MIC value of 200 µg/mL.

Abstract

A new species of Helicascus satunensis sp. nov. was collected on mature dead fruits of the Nypa palm in Satun Province, southern Thailand. Its morphological characteristics are similar to those of the genus Helicascus . Recently, a genus Helicascus with three species from marine habitats worldwide was studied. The morphology of this fungus was investigated and combined with multigene sequence analyzes of small subunit (SSU), large subunit (LSU), internal transcribed spacer (ITS) ribosomal DNA, translation elongation factor 1-alpha (TEF-1 α ) and RNA polymerase II (RPB2) genes. Morphologically, H. satunensis sp. nov. is characterized by semi-immersed, lenticular ascomata, multilocules, a bitunicate ascus and smooth, obovoid, dark brown ascospores that are one-septate and unequally two-celled. In addition, 3D visualization using synchrotron X-ray tomography was performed to investigate the interaction between fruiting body and substrata. Molecular phylogeny with multigene revealed that H. satunensis sp. nov. belongs to the family Morosphaeriaceae, order Pleosporales, class Dothideomycetes. Furthermore, H. satunensis sp. nov. forms a well-supported clade with Helicascus species described from marine habitats. Based on the unique morphological and molecular evidence, we propose this fungus, H. satunensis sp. nov., as a new species for Helicascus ., Competing Interests: The authors declare there are no competing interests., (©2024 Preedanon et al.)
