“…Interestingly, A. saccharicola , A. arundinis , and Arthrinium sp. 1 were found in both Sargassum fulvellum and the egg masses of A. japonicus [19] . A. japonicus spawns the largest number of eggs on Sargassum fulvellum , one of the major endophytic hosts of Arthrinium spp.…”

“…can easily be transferred to the egg masses of A. japonicus . In another study, the fungal diversity of the A. japonicus egg masses were investigated, and eight Arthrinium species were founded: A. saccharicola , A. sacchari , A. phaeospermum , A. arundinis , and A. rasikravindri , as well as three unknown Arthrinium species [19]. According to Park et al (2018), Arthrinium accounts for a small portion of the strains isolated from egg masses of A. japonicus .…”

In our previous study, all Arthrinium isolates from Sargassum sp. showed high bioactivities, but studies on marine Arthrinium spp. are insufficient. In this study, a phylogenetic analysis of 28 Arthrinium isolates from seaweeds and egg masses of Arctoscopus japonicus was conducted using internal transcribed spacers, nuclear large subunit rDNA, β-tubulin, and translation elongation factor region sequences, and their bioactivities were investigated. They were analyzed as 15 species, and 11 of them were found to be new species. Most of the extracts exhibited radical-scavenging activity, and some showed antifungal activities, tyrosinase inhibition, and quorum sensing inhibition. It was implied that marine algicolous Arthrinium spp. support the regulation of reactive oxygen species in symbiotic algae and protect against pathogens and bacterial biofilm formation. The antioxidant from Arthrinium sp. 10 KUC21332 was separated by bioassay-guided isolation and identified to be gentisyl alcohol, and the antioxidant of Arthrinium saccharicola KUC21221 was identical. These results demonstrate that many unexploited Arthrinium species still exist in marine environments and that they are a great source of bioactive compounds.

“…A total of 21 Penicillium strains were identified in this study. They were isolated from egg masses of Arctoscopus japonicus , mudflats, sea sand, and seaweeds by using previously described methods [10,13,27]. All plates were incubated at 25 °C for 7–15 days, and each Penicillium strain was transferred to a new PDA plate.…”

Species that belong to Penicillium section Sclerotiora are commonly found in various terrestrial environments, but only a few have been reported in marine environments. Because the number of Penicillium species reported in marine environments is increasing, we investigated the diversity of Penicillium section Sclerotiora in marine environments in Korea. Based on sequence analyses of β-tubulin and calmodulin loci, 21 strains of section Sclerotiora were identified as P. bilaiae , P. daejeonium , P. exsudans , P. herquei , P. cf. guanacastense , P. mallochii , P. maximae , and P. viticola . Three of them were confirmed as new to Korea: P. exsudans , P. mallochii , and P. maximae . Here, we have provided detailed morphological descriptions of these unrecorded species.

“…To date, Penicillium has been reported in 25 sections of 345 species worldwide through the use of standardized methods [9]. In Korea, approximately 102 Penicillium species from terrestrial environments [10,11] and 100 Pencillium species from marine environments [12][13][14][15][16][17] have been reported. It was confirmed that many Pencillium species from marine environments are different from those found in terrestrial environments.…”

Penicillium, the most common genus plays an important ecological role in various terrestrial and marine environments. However, only a few species have been reported from rhizosphere soil. As part of a project to excavate Korean indigenous fungi, we investigated rhizosphere soil of six plants in the forest (terrestrial habitat) and sand dunes (coastal habitat) and focused on discovering Penicillium species. A total of 64 strains were isolated and identified as 26 Penicillium species in nine sections based on morphological characteristics and the sequence analysis of b-tubulin and calmodulin. Although this is a small-scale study in a limited rhizosphere soil, eight unrecorded species and four potential new species have been identified. In addition, most Penicillium species from rhizosphere soil were unique to each plant.
