We evaluated endolithic fungal diversity associated with rocks sampled at the polyextreme Brazilian São Pedro and São Paulo archipelago using a DNA amplicon metagenomics approach. We detected 808,547 fungal DNA reads grouped into 92 amplicon sequence variants (ASVs). The rocks sampled were geologically characterized as mylonitized peridotites, serpentinized peridotites, and carbonate-matrix sedimentary breccias. Ascomycota was...

Yeasts can produce microbial oil from hydrophobic substrates such as glycerol, a byproduct of the biodiesel industry that is often undervalued in the market. Yarrowia lipolytica is capable of degrading glycerol and is considered a model organism for studying lipid accumulation. Different yeast strains and culture conditions can result in varying lipid yields with distinct fatty acid profiles. Thus, in this study, five strains...

This study investigated the diversity of Alternaria and Fusarium species in atmospheric aerosols and plant tissue in a common wheat crop in NW Spain. The relationship between atmospheric fungal spore concentrations and weather conditions was analysed. To this end, non-viable and viable aerobiological monitoring methodologies were combined with isolates from plants showing symptoms of fungal infection. The isolates were identif...

Purpose Strongyloidiasis is an intestinal helminthiasis that can induce structural alterations in the intestinal mucosa during infection. The present study evaluated histomorphometric alterations of the small intestine in mice experimentally infected with Strongyloides venezuelensis and treated with Rosmarinus officinalis essential oil. Methods Infected animals were treated orally with R. officinalis essential oil (200 or 400...

Understanding resource partitioning and niche segregation is crucial for explaining coexistence among seabirds. During the breeding season, colonial seabirds, such as storm-petrels, act as central-place foragers and face strong competition for resources. This study focused on intersexual niche segregation and interspecific differences in two sympatric storm-petrel species, the Black Storm-petrel ( Hydrobates melania ) and Leac...

Zoonotic parasites are an increasingly recognised challenge for seafood safety. Anisakid nematodes currently represent the most significant fish‐borne parasitic threat in Atlantic wild fisheries. Recent regional surveys and global syntheses suggest significant increases in the prevalence and intensity of anisakid infections across multiple commercially important fish species, raising concerns for public health, marketability a...

Background and aims Legume residues are important organic inputs, but their effects depend on residue chemistry and application rate. This study examined how pea ( Pisum sativum ) and field bean ( Vicia faba ) residues with contrasting phytochemical compositions influenced soil functioning and subsequent barley growth, assessing how residue quality and dose shape soil responses. Methods A sandy loam soil was amended with resid...

Microbial pigments have been gaining prominence as sustainable alternatives to synthetic dyes, which are often associated with environmental impacts and potential health risks. A wide range of microorganisms, including bacteria, fungi and yeasts, are capable of producing pigments of industrial interest. Despite their potential, large-scale production still faces challenges related to cultivation costs and, in particular, extra...

The valorization of fruit peel waste through microwave-assisted co-pyrolysis (MACP) offers a sustainable pathway for producing high-performance functional materials. This study employed a Central Composite Design (CCD) and multi-objective desirability function to engineer biochars tailored for soil amendment (BCop-bf) and pollutant adsorption (BCop-ads). Synergistic effect analysis provided empirical evidence of the superiorit...
