Epiphytic and endophytic microbiome of the seagrass Zostera marina: Do they contribute to pathogen reduction in seawater? THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 908:168422.

Abstract
Seagrass meadows provide crucial ecosystem services for coastal environments and were shown to reduce the abundance of waterborne pathogens linked to infections in humans and marine organisms in their vicinity. Among potential drivers, seagrass phenolics released into seawater have been linked to pathogen suppression, but the potential involvement of the seagrass microbiome has not been investigated. We hypothesized that the microbiome of the eelgrass Zostera marina, especially the leaf epiphytes that are at direct interface between the seagrass host and the surrounding seawater, inhibit waterborne pathogens thereby contributing to their removal. Using a culture-dependent approach, we isolated 88 bacteria and fungi associated with the surfaces and inner tissues of the eelgrass leaves (healthy and decaying) and the roots. We assessed the antibiotic activity of microbial extracts against a large panel of common aquatic, human (fecal) and plant pathogens, and mined the metabolome of the most active extracts. The healthy leaf epibiotic bacteria, particularly Streptomyces sp. strain 131, displayed broad-spectrum antibiotic activity superior to some control drugs. Gram-negative bacteria abundant on healthy leaf surfaces, and few endosphere-associated bacteria and fungi also displayed remarkable activities. UPLC-MS/MS-based untargeted metabolomics analyses showed rich specialized metabolite repertoires with low annotation rates, indicating the presence of many undescribed antimicrobials in the extracts. This study contributes to our understanding on microbial and chemical ecology of seagrasses, implying potential involvement of the seagrass microbiome in suppression of pathogens in seawater. Such effect is beneficial for the health of ocean and human, especially in the context of climate change that is expected to exacerbate all infectious diseases. It may also assist future seagrass conservation and management strategies.

Abstract
IMPORTANCE Candida albicans is an important human pathogen that can cause lethal systemic infections. The ability of C. albicans to colonize and establish infections is closely tied to its highly adaptable nature and capacity to resist various types of stress, including oxidative stress. Previous studies showed that four C. albicans proteins belonging to the flavodoxin-like protein family of quinone reductases are needed for resistance to quinones and virulence. Therefore, in this study, we examined the role of a distinct type of quinone reductase, Zta1, and found that it acts in conjunction with the flavodoxin-like proteins to protect against oxidative stress.

Abstract
The fungal pathogen Candida albicans is capable of causing lethal infections in humans. Its pathogenic potential is due in part to the ability to resist various stress conditions in the host, including oxidative stress. Recent studies showed that a family of four flavodoxin-like proteins (Pst1, Pst2, Pst3, Ycp4) that function as quinone reductases promotes resistance to oxidation and is needed for virulence. Therefore, in this study Zta1 was examined because it belongs to a structurally distinct family of quinone reductases that are highly conserved in eukaryotes and have been called the ζ-crystallins. The levels of Zta1 in C. albicans rapidly increased after exposure to oxidants, consistent with a role in resisting oxidative stress. Accumulation of reactive oxygen species was significantly higher in cells lacking ZTA1 upon exposure to quinones and other oxidants. Furthermore, deletion of ZTA1 in a mutant lacking the four flavodoxin-like proteins, resulted in further increased susceptibility to quinones, indicating that these distinct quinone reductases work in combination. These results demonstrate that Zta1 contributes to C. albicans survival after exposure to oxidative conditions, which increases the understanding of how C. albicans resists stressful conditions in the host.

Abstract
Endophytic fungi comprise host-associated fungal communities which thrive within the tissues of host plants and produce a diverse range of secondary metabolites with various bioactive attributes. The metabolites such as phenols, polyketides, saponins, alkaloids help to mitigate biotic and abiotic stresses, fight against pathogen attacks and enhance the plant immune system. We present an overview of the association of endophytic fungal communities with a plant host and discuss molecular mechanisms induced during their symbiotic interaction. The overview focuses on the secondary metabolites (especially those of terpenoid nature) secreted by endophytic fungi and their respective function. The recent advancement in multi-omics approaches paved the way for identification of these metabolites and their characterization via comparative analysis of extensive omics datasets. This study also elaborates on the role of diverse endophytic fungi associated with key agricultural crops and hence important for sustainability of agriculture.

Abstract
Quinones are widespread in plants, animals, insects, and microorganisms. Several anticancer agents contain quinone structures as critical parts to show remarkable potential and distinctive modes of actions. The purpose of this study was to investigate the structure-activity relationships of microbial quinones and their derivatives as anticancer agents. A series of p-terphenylquinone and seriniquinone derivatives were therefore prepared. Treatment of the synthesized quinones possessed antiproliferative activity on human leukemia HL-60 cells in a dose-dependent fashion. In addition, seriniquinone derivatives elevated cellular reactive oxygen species (ROS) levels, thereby triggering the ensuing apoptotic events. Our findings emphasize the excellent potential of seriniquinone derivatives as redox cycling-induced ROS-modulating anticancer agents.

Abstract
Fungal quinones can be used for a variety of applications, such as pharmaceuticals, food colorants, textile dyes, and battery electrolytes. However, when producing quinones by fungal cultivation, many considerations arise regarding the feasibility of a production system, such as the quinone yield, purity, ease of extraction, and the co-production of mycotoxins. In this work, we display the initial screening of filamentous fungi for quinone production and evaluate their potential for future optimization. We investigated toluquinone (TQ) potentially produced by Penicillium cf. griseofulvum, terreic acid (TA) produced by Aspergillus parvulus and A. christenseniae, and anthraquinone (AQ) monomers and dimers produced by Talaromyces islandicus. The strains grew on various agar and/or liquid media and were analyzed by ultra-high-performance liquid chromatography–diode array detection–quadrupole time-of-flight mass spectrometry (UHPLC-DAD-QTOF MS). In the case of AQs, feature-based molecular networking (FBMN) was used for the identification of AQ analogs. TQ was not observed in the production strains. TA constituted one of the major chromatogram peaks and was secreted into the growth medium by A. parvulus. The AQs constituted many major chromatogram peaks in the mycelium extracts and endocrocin and citreorosein were observed extracellularly in small amounts.

Abstract
Society faces the challenge of storing energy from sustainable sources in inexpensive, nontoxic ways that do not deplete the limited resources of Earth. In this regard, quinone redox flow batteries have been proposed as ideal; however, industrially used quinones have traditionally been synthesized from fossil fuels. Therefore, we investigated the production of phoenicin (compound 1), a deep violet dibenzoquinone produced by certain Penicillium species, for its industrial potential. Strains grew as surface cultures on customized growth media with varying production parameters, and phoenicin production was assessed by ultrahigh-performance liquid chromatography-diode array detection-quadrupole time of flight mass spectrometry (UHPLC-DAD-QTOF MS) analysis of the supernatant. Phoenicin production was reliant on the sucrose concentration, and by varying that, we produced 4.94 ± 0.56 g/L phoenicin on a Czapek yeast autolysate broth (CY)-based medium with Penicillium phoeniceum (CBS 249.32) as the production host, with 71.91% phoenicin purity in the resulting medium broth. Unexpectedly, metabolites corresponding to phoenicin polymers were tentatively identified in P. phoeniceum, of which the dimer (diphoenicin) was a major chromatographic peak. An MS-based metabolomics study was conducted on P. atrosanguineum using feature-based molecular networking and multivariate statistics, and it was found that few or no known secondary metabolites besides phoenicin were secreted into the growth medium. Finally, the effects of sucrose, sodium nitrate, and yeast extract (YE) in the growth medium were investigated in a 23 full factorial design. The results indicated an optimal sucrose concentration of 92.87 g/L on CY when NaNO3 and YE were fixed at 3 and 5 g/L, respectively. IMPORTANCE This work was undertaken to explore the production of fungal quinones in wild-type strains for use as electrolytes in redox flow batteries. As society converts energy production in a more sustainable direction, it becomes increasingly more important to store sustainable energy in smart ways. Conventional battery technologies imply the use of highly toxic, expensive, and rare metals; thus, quinone redox flow batteries have been proposed to be a desirable alternative. In this study, we explored the possibility of producing the fungal quinone phoenicin in Penicillium spp. by changing the growth parameters. The production of other secondary metabolites and known mycotoxins was also investigated in a metabolomics study. It was shown that phoenicin production was activated by optimizing the carbon concentration of the medium, resulting in high titers and purity of the single metabolite.
