Nitrospina bacteria in a rocky intertidal habitat (Quintay Bay, central Chile)

MicrobiologyOpen, Volume 8, Issue 3, March 2019., 2019
Ecology of microorganisms in natural environments. Expanded distribution of marine Nitrospina. Rocky intertidal gradients. Abstract Nitrospina bacteria are among the most important nitrite oxidizers in coastal and open‐ocean environments, but the relevance of the genus contrasts with the scarceness of information on their ecophysiology and habitat ...

Environmental Contamination Affects Associated Bacterial Communities in a Neotropical Arboreal Ant

Biotropica, Volume 58, Issue 3, May 2026.
Environmental stressors such as contamination from mining tailings can alter microbial communities associated with insects, including social ants. Ants, as widespread and ecologically influential insects with stable microbial associations, offer a relevant model to examine these effects.

Active microbiome structure and its association with environmental factors and viruses at different aquatic sites of a high‐altitude wetland

MicrobiologyOpen, Volume 8, Issue 3, March 2019., 2019
Archaeal and bacterial active community structure and its association with physicochemical parameters and viruses from different aquatic ecosystems (i.e., ponds, springs, and lagoon) at a high‐altitude wetland (Salar de Huasco), northern Chile. Abstract Salar de Huasco is a high‐altitude wetland characterized by a highly diverse microbial life adapted ...

Metabarcoding Analysis Reveals Microbial Diversity and Its Environmental Drivers in the Pantanos de Villa Lagoons in Lima—Peru

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study characterized, for the first time, the microbial diversity in four lagoons of the Pantanos de Villa Wildlife Refuge in Lima, Peru, using 16S rRNA marker gene metabarcoding and identified the physicochemical drivers that influence the microbial community structure of these lagoons.

Microbial and Natural Metabolites That Inhibit Splicing: A Powerful Alternative for Cancer Treatment

BioMed Research International, Volume 2016, Issue 1, 2016., 2016
In eukaryotes, genes are frequently interrupted with noncoding sequences named introns. Alternative splicing is a nuclear mechanism by which these introns are removed and flanking coding regions named exons are joined together to generate a message that will be translated in the cytoplasm. This mechanism is catalyzed by a complex machinery known as the

Piper auritum (Kunth) Fungal Endophytes: A Source of Metabolites to Inhibit the Formation of Advanced Glycation End Products

Chemistry &Biodiversity, Volume 22, Issue 10, October 2025.
Endophytic fungi of P. auritum were evaluated for their ability to produce inhibitors of formation of advanced glycation end products (AGEs). Neopestalotiopsis sp. H2 and Diaporthe sp. H5 extracts were the most active. So, we performed their chemical profiling by untargeted and phenolics‐targeted metabolomic approaches to identify the potential ...

Field Studies on the Relationship between Fusarium verticillioides and Maize (Zea mays L.): Effect of Biocontrol Agents on Fungal Infection and Toxin Content of Grains at Harvest

International Journal of Agronomy, Volume 2011, Issue 1, 2011., 2011
Maize (Zea mays L.) is a staple food for the majority of the world′s population. Fusarium verticillioides (Sacc.) Nirenberg (Teleomorph: Gibberella moniliformis Wineland; synonym: F. moniliformis) is both a saprophyte and a parasite of maize and can also be found as an endophyte.

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.
