Low impact of Zostera marina meadows on sediment and water microbiota under brackish conditions

Environmental Microbiome, Год журнала: 2025, Номер 20(1)

Опубликована: Янв. 11, 2025

Abstract Background Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments water. Z. typically found marine systems, but it can also proliferate under brackish conditions. Changes salinity generally have a strong impact on biota, especially at salty divide between 6 9. To better understand of interaction sediment microbiota, we investigated effects meadows across range 6–15 Baltic Sea during summer using 16S 18S rRNA gene amplicon sequencing. Results Salinity was most factor for structuring within both sediment. The presence affected composition bacterial eukaryotic community alpha diversity However, this effect confined to alpha-mesohaline conditions (salinity 9–15). below 9 insignificant. Conclusions Increasing associated with longer leaf length , causing increased canopy height, which affects through reduced velocity. Hence, propose that may be major predictor explaining ’s interactions 9–15. These findings emphasize importance physical meadow services implications management changing climate.

Antibacterial insights into alternariol and its derivative alternariol monomethyl ether produced by a marine fungus

Applied and Environmental Microbiology, Год журнала: 2024, Номер 90(4)

Опубликована: Апрель 17, 2024

ABSTRACT Alternaria alternata FB1 is a marine fungus identified as candidate for plastic degradation in our previous study. This has been recently shown to produce secondary metabolites with significant antimicrobial activity against various pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and the notorious aquaculture pathogen Vibrio anguillarum . The antibacterial compounds were purified alternariol (AOH) its derivative, monomethyl ether (AME). We found that AOH AME primarily inhibited pathogenic bacteria (MRSA or V. ) by disordering cell division some other key physiological biochemical processes. further demonstrated could effectively inhibit unwinding of MRSA topoisomerases, which are closely related potential action target AOH. activities verified using zebrafish vivo model. Notably, did not significantly affect viability normal human liver cells at concentrations Finally, we developed genetic operation system A. blocked biosynthesis knocking out omtI (encoding an O-methyl transferase), facilitated only development this will accelerate discovery novel natural products bioactivity IMPORTANCE More more scientific reports indicate derivative (AME) exhibit activities. However, limited exploration their detailed mechanisms performed. In present study, produced disclosed vitro Given low toxicity on line under exhibiting different proposed be good candidates developing promising antibiotics also succeeded blocking AME, us easily obtain pure Moreover, based results, was enable polyethylene degradation.

Revealing the potential of biochar for heavy metal polluted seagrass remediation from microbial perspective

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 292, С. 117991 - 117991

Опубликована: Март 1, 2025

Seagrass meadows are under threat due to climate change and human activities, including heavy metal contamination, which can accumulate in seagrass tissues harm their health productivity. Despite extensive research, effective remediation strategies lacking. This study investigated biochar's potential as a agent for affected by pollution. Heavy pollution was simulated adding copper (Cu) chromium (Cd) Thalassia hemprichii, the effects of biochar were evaluated monitoring physiology, root-associated microbial communities, concentrations. Seagrasses metals, adversely affect alter communities. may resist stress releasing dissolved organic carbon (DOC) recruiting beneficial bacteria. Biochar reduced bioavailability restored ecosystem health, evidenced community dynamics. highlights promising role meadow restoration impacted

Societal value of seagrass from historical to contemporary perspectives

AMBIO, Год журнала: 2025, Номер unknown

Опубликована: Март 24, 2025

Seagrasses have been entwined with human culture for millennia, constituting a natural resource that has supported humanity throughout this history. Understanding the societal value of seagrass fosters appreciation these ecosystems, encouraging conservation and restoration actions to counteract historic predicted losses. This study overviews plethora use in history, ranging from spiritual ceremonial roles, direct indirect food resources, medicines raw materials, dating back more than 180 000 years. While many past uses abandoned modern societies, others persisted or are being rediscovered, new applications emerging. As seagrasses depend on harvesting, we also underscore need sustainable practices (re)generate positive interactions between society. Our review contributes revalue ecosystem services, highlighting ancient recent relationships incentivize actions.

A Helping Hand: Fungi, as Well as Bacteria, Support Ecophysiological Descriptors to Depict the Posidonia oceanica Conservation Status

Water, Год журнала: 2025, Номер 17(8), С. 1151 - 1151

Опубликована: Апрель 12, 2025

The crucial role of plant–microbe interactions in seagrass growth and overall fitness is widely recognized known to influence plant response stress. Human-induced changes coastal ecosystems necessitate efficient descriptors for monitoring. Recently, Posidonia oceanica meadows, an integrative approach combining ecophysiological with bacterial communities has been successfully applied. Conversely, the mycobiota remains largely unexplored fungal cannot be included yet as a putative descriptor. This study aims evaluate ecological status two P. meadows Akrotiri Bay (Cyprus), located under different geomorphological features (depth seabed type) degrees human pressure (port proximity vs. Marine Protected Area). A set including morphometry, biochemical markers collected 2023 are compared those collected, at same sites, 2017. Furthermore, investigation leaf-associated microbial community underrepresented communities, addition ones, their usefulness evaluating conservation status. Results indicated good both showing amelioration Limassol port meadow from In 2023, biometrical/biochemical were found comparable across sites differing 2017 results. Noteworthy, exhibited significant differences between clear reduction, meadow, dominant Posidoniomyces atricolor which specific colonizer roots. These results confirm strong relationship host, suggest its sensitivity environmental changes, able keep track shifts.
