Arsenic contamination of drinking water threatens more than 100 million people worldwide, particularly in regions where decentralized, low-cost treatment solutions are urgently needed. Although biochar-based adsorbents have shown promise, the perform...
The limited accessibility of fermentable substrates in marine macroalgal biomass constrains efficient biohydrogen production. This study evaluated thermal, disperser and biosurfactant pretreatments individually and in combination to enhance Ulva reti...
Macroalgal surfaces harbor epiphytic bacterial communities with potential roles in host metabolism, stress tolerance, chemical defense, and ecological interactions, yet their genome-resolved diversity remains poorly characterized across major macroal...
The marine microalga Nannochloropsis oceanica is a promising organism for sustainable production of lipids, omega-3 fatty acids, and biomass with a high nutritional value. We demonstrate UV mutagenesis combined with visual screening to generate novel...
Macrobenthic seaweeds are key species in temperate and boreal nearshore rocky ecosystems, and their interspecific interactions profoundly affect the species composition, spatial distribution and dynamic succession of the community. This paper systema...
Many red algal species described solely from morphology have historically been assigned to inappropriate genera because of superficial morphological similarity. Laurencia chilensis, originally described for specimens from Chile, has long been recogni...
The cultivation of Chondracanthus chamissoi has advanced in Chile and Peru, but seedstock production still depends on thalli collected from natural beds. This dependence may limit commercial scale-up and increase pressure on natural beds. This study...
Abiotic stresses severely limit agricultural productivity and have stimulated growing interest in microalgae as sources of stress-resilient traits and biostimulants. However, comparative genomic assessments integrating multiple stress-associated gene...
Microalgae biomanufacturing is a promising technology that converts carbon dioxide into valuable products. However, it faces limitations in scaling, online monitoring, and controlling biological variables. In photobioreactors, light intensity influen...
Anthropogenic pollution of aquatic ecosystems presents a significant global challenge, underscoring the urgent need for resilient, biologically mediated remediation strategies. In this context, microalgae have emerged as a compelling solution, owing...
We reexamined the critical importance of water motion in measuring algal growth and photosynthetic rates, addressing a significant limitation in traditional static incubation approaches. It presents a comprehensive framework for dynamic measurement m...
The association of microalgae with aquatic animal egg masses plays an important role in the reproductive ecology of several species. The first descriptions of this phenomenon were reported in 1888 for the egg masses of the spotted salamander Ambystom...
Cyanobacteria are prolific producers of secondary metabolites, some of which are potent cyanotoxins that threaten ecosystem integrity and human health. Although blooms have been extensively studied in temperate regions, Southeast Asia’s (SEA&rs...
The Murmansk Region (the Russian Arctic) faces severe environmental degradation due to heavy metal (HM) pollution from copper–nickel smelting, resulting in vast industrial barrens with elevated concentrations of copper (Cu) and nickel (Ni). Con...
DNA barcoding is a reliable technique for seaweed identification. However, high concentrations of sulfated polysaccharides and secondary metabolites hinder the extraction of DNA templates of suitable quality. Therefore, this study assessed four DNA e...
Microalgal growth-promoting bacteria (MGPBs) represent a promising strategy to enhance biomass productivity, yet the mechanistic basis of these mutualistic interactions remains poorly understood. Here, we isolated a new MGPB, Cupriavidus oxalaticus M...
Interactions between cyanobacteria and eukaryotic algae are traditionally viewed as favoring cyanobacteria, which are often the dominant competitors in freshwater ecosystems. However, increasing evidence suggests that eukaryotic algae also possess ef...
The pet food industry is undergoing a significant transformation, driven by the growing trend of companion animal humanization and increasing concerns over the environmental sustainability of conventional protein and lipid sources. Consumers now seek...
Using multivariate analysis in three zones of the Great Atlantic Sargassum Belt (GASB), we found close associations between the density of sargassum, dust deposition, and surface iron concentration on the sea surface during 2002–2010, before th...
Microalgae represent a promising raw material for the bioeconomy and biotechnology. One of the key factors regulating their metabolism is light. However, the traditional approach to cultivation, aimed at maximising biomass productivity due to high li...
Water pollution can compromise the ecological integrity of freshwater habitats, thereby exposing freshwater communities to sources of pollution such as wastewater and agricultural and industrial discharges. Diatoms are key organisms because of their...
Freshwater phytoplankton communities are currently being influenced by ongoing climate change. This study aimed to investigate the effects of warming and dissolved inorganic carbon (DIC) on chlorophyll-a concentration and physicochemical variables in...
Sargassum muticum is an invasive brown macroalga that has rapidly expanded along the Moroccan Atlantic coast, posing ecological challenges while representing an abundant marine biomass with potential biotechnological value. This study investigated th...
The evolution of plant cell walls was critical for land colonization, yet its genetic basis remains incompletely understood. Charophyte green algae are the closest relatives of land plants and provide key insights into the origins of cell wall biosyn...
The global crisis of expanded polystyrene (EPS) waste and the rising demand for affordable water purification technologies necessitate the development of sustainable, high-performance filtration materials. This study reports the successful upcycling...
Forensic diagnosis of drowning remains challenging because postmortem findings are often supportive rather than pathognomonic. The classical diatom test has long been used as an ancillary tool, but its interpretation remains controversial because of...
Since 2011, Caribbean and West African countries have experienced the deposit of millions of tonnes of the pelagic brown seaweed sargassum. While these algal blooms are well documented in the Caribbean, less information is available on the occurrence...
Among cyanobacterial genera, Microcystis spp. dominate aquatic systems and form harmful algal blooms (HABs) under favorable environmental conditions, such as temperature and nitrogen availability. Numerous studies have examined the effects of these d...
The rare charophyte species Chara corfuensis, which has an almost exclusively Mediterranean distribution, was recorded for the first time in two small waterbodies in southern Serbia, deep inland and far from the coast. Habitat characteristics were de...
The red macroalga Halymenia durvillei is a cultivated tropical biomass with potential for aqueous recovery of phycoerythrin (PE)-containing fractions. This study investigated the effects of biomass-to-solvent ratio, extraction temperature, extraction...
Oyster-associated microbiomes represent a dynamic interface between marine hosts and their environment, yet the diversity, evolution, and functional potential of their associated cyanobacteria remain poorly understood. For microbial organisms, such a...
Phytoplankton are the major primary producers in the Southern Ocean, are important to global nutrient cycles, and are at the base of marine food webs. Polar ecosystems are unique in their extended periods of darkness in the winter, and prolonged dark...
Sargassum fusiforme is a commercially important macroalga in Eastern Asia. To support the conservation and restoration of S. fusiforme populations, we investigated its predominant reproductive mode using a population genetics approach. Two sampling s...
Perennially ice-covered lakes in the McMurdo Dry Valleys, Antarctica, are shaped by permanent stratification, extreme oligotrophy, and salinity gradients, yet these features are vulnerable to climate-driven hydrologic change. Because phytoplankton an...
