Freshwater ascomycetes are a group of fungi of great ecological importance because they are involved in decomposition processes and the recycling of organic matter in aquatic ecosystems. The taxonomy of these fungi is complex, with representatives in several orders of the phylum Ascomycota. In the present study, we collected ninety-two samples of plant debris submerged in freshwater in different locations in Spain. The plant specimens were placed in wet chambers and developed several fungi that were later isolated in pure culture. A main phylogenetic tree using the nucleotide sequences of D1-D2 domains of the 28S nrRNA gene (LSU) was built to show the taxonomic placement of all our fungal strains, and, later, individual phylogenies for the different families were built using single or concatenated nucleotide sequences of the most suitable molecular markers. As a result, we found a new species of that produces a coelomycetous asexual state, a new species of that produces an asexual state, a new species of that forms both sexual and asexual states in vitro, and the sexual states of two species of none of which have been reported before for these genera. In addition, we describe a new species of characterized by the production of copper-colored globose conidiomata, and of , which produces well-developed conidiophores.

Harmful cyanobacterial blooms (HCB) have become a common issue in freshwater worldwide. Biological methods for controlling HCB are relatively cost effective and environmentally friendly. The strain of ascomycete GF6 was isolated from a water sample collected from the estuarine zone of the eastern part of the Gulf of Finland.

Lichen-associated endophytic Actinobacteria, particularly Streptomyces species, are recognized for their production of bioactive secondary metabolites with significant pharmaceutical potential. With the escalating prevalence of diseases, Streptomyces species are being investigated for its natural source of antimicrobial compounds for new antibiotics. This study focuses on the bioactive properties of secondary metabolites from lichen-associated endophytic Actinobacteria, focusing on Streptomyces glaucescens NTSB-37 isolated form lichen, Parmotrema perlatum (Huds.

Eurotiales fungi are thought to be distributed worldwide but there is a paucity of information about their occurrence on diverse substrates or hosts and at specific localities. Some of the Eurotiales, including Aspergillus and Penicillium species, produce an array of secondary metabolites of use for agricultural, medicinal, and pharmaceutical applications. Here, we carried out a survey of the Eurotiales in South Korea, focusing on soil, freshwater, and plants (dried persimmon fruits and seeds of Perilla frutescens, known commonly as shiso).

Plant-growth-promoting (PGP) endophytic bacteria are beneficial microorganisms that can help plants withstand biotic stress caused by fungal phytopathogens. In the present study, 78 endophytic bacterial isolates were isolated from chilli (Capsicum annuum L.).
