Bio-guided screening is an important method to identify bioactive compounds from fungi. In this study we applied a fast digital time-lapse microscopic method for assessment of the antibacterial properties of secondary metabolites from the fungal genus Fusarium. Here antibacterial effects could be detected for antibiotic Y, aurofusarin, beauvericin, enniatins and fusaric acid after six hours of cultivation. The system was then used in a bio-guided screen of extracts from 14 different Fusarium species, which had been fractionated by HPLC. In this screen, fractions containing the red pigments aurofusarin and bikaverin showed effects against strains of Lactobacillus and Bifidobacterium. The IC50 for aurofusarin against Lactobacillus acidophilus was 8 mu M, and against Bifidobacterium breve it was 64 mu M. Aurofusarin only showed an effect on probiotic bacteria, leading to the speculation that only health-promoting bacteria with a positive effect in the gut system are affected.

Cyclic, Hydrophobic Hexapeptide Fusahexin Is the Product of a Nonribosomal Peptide Synthetase in Fusarium graminearum

Klaus R. Westphal, Simone Bachleitner, Manja M. Severinsen, Mathias L. Brundto, Frederik T. Hansen, Trine Sorensen, Rasmus D. Wollenberg, Erik Lysoe, Lena Studt, Jens L. Sorensen, Teis E. Sondergaard, Reinhard Wimmer

Summary: The plant pathogenic fungus Fusarium graminearum was found to produce a new cyclic hexapeptide named fusahexin, and a biosynthetic model for it was proposed based on the structure of fusahexin and the domain architecture of NRPS4. NRPS4 gene cluster plays a significant role during infection and oxidative and osmotic stress, making it an important pathogen in plant infection.

High molecular weight DNA extraction methods lead to high quality filamentous ascomycete fungal genome assemblies using Oxford Nanopore sequencing

Summary: In the past two decades, whole-genome sequencing has greatly impacted genetic research in various kingdoms, including fungi. With the advancement of third-generation long-read DNA sequencing, highly contiguous assemblies can be obtained, but the challenge lies in extracting high molecular weight DNA, particularly from species with cell walls like fungi. Developing efficient extraction and purification methods is crucial for obtaining quality DNA for sequencing, and the study successfully demonstrated two straightforward methods for extracting high quality, high molecular weight DNA from filamentous ascomycetes, resulting in complete and contiguous assemblies for haploid fungal genomes.

Summary: Apiospora and Arthrinium have undergone significant changes in phylogenetic affiliation in the past decade. They have recently been divided into two separate clades, with Apiospora being the majority and several species changing from Arthrinium to Apiospora. The first genome annotation was available in 2020, revealing the high potential for novel secondary metabolite production in these unexplored genera. This review presents the current knowledge of 269 secondary metabolites isolated from these fungal genera, highlighting compounds with known biological or toxic effects.

Summary: This study demonstrates the influence of phoenicin and its dimer on the capacity performance of phoenicin as a negolyte in a redox flow battery. The biosynthesized fungal quinone mix of phoenicin shows the ability to store four electrons per phoenicin molecule in a redox flow battery negolyte. A detailed analysis is conducted to understand the chemical stability of phoenicin in an alkaline environment.

Are biologically synthesized electrolytes the future in green energy storage?

Charlotte Overgaard Wilhelmsen, Jens Muff, Jens Laurids Sorensen

Summary: The production of renewable energy from solar panels and windmills has been growing rapidly in recent years. However, a major obstacle in the green transition is the need for cost-efficient energy storage to fully exploit their potential. A promising solution is the use of redox flow batteries (RFBs) with quinones as electron carriers. Currently, quinones derived from crude oil are used, which does not align with the goal of sustainable energy production from renewable sources. Recent research has shown that filamentous fungi have great potential for quinone production, and a proof-of-concept RFB using fungal-produced quinones has been developed. We discuss the challenges that need to be addressed before fungal-produced quinone RFBs can be applied in the green transition.

6-MSA, a secondary metabolite distribution hub with multiple fungal destinations

Mihaela Bejenari, Teis Esben Sondergaard, Jens Laurids Sorensen

Summary: 6-methylsalicylic acid (6-MSA) is a small polyketide produced by fungi through horizontal gene transfer, serving as a metabolic hub for the production of various complex compounds. The most significant metabolite derived from 6-MSA is the mycotoxin patulin. Other important products include terreic acid and yanuthones. The aculin biosynthetic pathway demonstrates the most advanced modification of 6-MSA, involving non-ribosomal peptide synthase and terpene cyclase. This review summarizes the pathways originating from 6-MSA, gene clusters involved, and resulting biosynthetic pathways.

Summary: In this study, researchers sequenced 93 Penicillium isolates and established a species phylogeny and pangenome. They found that approximately half of the genes are shared among 98 or more isolates. They also discovered 15 lateral gene transfer events that have played a role in the evolution and adaptation of these fungi. This comprehensive characterization of the Penicillium genus surpasses single-reference genomes and captures the genetic variation.

Summary: This study investigates the life cycle and metabolome of the pathogenic fungus Fusarium graminearum, which has significant impacts on agriculture and human health. A previously unknown polyketide from the PKS2 gene cluster was identified and named fugralin A and B. Functional characterization showed that these compounds are not produced during infection and do not affect pathogenicity or visual growth. The compounds are volatile, suggesting potential functions for further investigation.
