Microbioma
Los avances en la investigación del microbioma impulsan la innovación en salud, agricultura y biotecnología a través de la comprensión de las comunidades microbianas y sus interacciones.

El ámbito del microbioma se centra en las complejas comunidades de microorganismos que habitan diversos entornos, en particular dentro de organismos huéspedes, y sus genomas colectivos. En este campo se integran la metagenómica, la ecología, y las interacciones huésped-microbio para dilucidar la diversidad microbiana, el potencial funcional y la dinámica que influyen en la salud, la enfermedad y los procesos medioambientales. Las investigaciones abarcan la colonización microbiana, la disbiosis, la producción de metabolitos y la modulación del microbioma mediante intervenciones como los probióticos y los trasplantes. La siguiente recopilación presenta publicaciones científicas recientes e innovaciones patentadas que permiten avanzar en la comprensión de la estructura y la función de la comunidad microbiana, así como de sus aplicaciones en medicina, agricultura y biotecnología:

Published on 2026-05-27 by Hirohito Yamasaki, Yui Iwamoto, Taiji Ito, Kimitoshi Fukunaga @NATURE

Abstract: Polymer Journal, Published online: 27 May 2026; doi:10.1038/s41428-026-01203-3We prepared a mixed-type PVA spherical hydrogel (PVA-mix-βCyD/HDI) was prepared, in which βCyD/HDI was accumulated and distributed at contents of 18–55 μmol g−1. The internetwork distance on the hydrogel surface increased from ~20 to 30 μm as the amount of β-CyD increased, as confirmed by SEM cross-sectional images. This trend is opposite to that observed for the homogeneously dispersed PVA-co-βCyD hydrog[...]


Our summary: The study investigates the ecological characteristics of β-cyclodextrin-bearing PVA hydrogels for microbial immobilization. A mixed-type PVA hydrogel was prepared, showing increased internetwork distance with higher β-CyD content. PhOH-degrading bacteria were effectively immobilized, enhancing degradation rates as β-CyD concentration increased.

Microplastic contamination and the benefits of blue flag beach status

Published on 2026-05-06 by @OXFORD

Abstract: AbstractThis study aimed to determine the effect of “Blue Flag” status, an award that reflects a strong dedication to the sustainable management and protection of coastal resources, on the level of microplastic (MP) in beach samples. Quantitative determination of MPs was carried out at two beach locations in Greece, a Blue Flag beach in Glyfada, Attica, and beaches of the remote island of Leros without Blue Flag status. Samples of surface sand sampled at a maximum depth of 3 cm were taken a[...]


Our summary: This study evaluates the impact of Blue Flag status on microplastic levels at beaches in Greece. Samples from a Blue Flag beach showed significantly lower microplastic contamination compared to non-Blue Flag beaches. The findings suggest that Blue Flag designation contributes to better beach management and environmental protection.
