Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1835-1860, July/August 2026.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Turning Mediterranean Farmlands Into Priority Habitats: Natural Expansion of Juniper Woodlands After Agricultural Abandonment

open access: yesJournal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Spanish juniper woodlands are expanding across central Spain as farmland is abandoned. By combining 34 years of land‐cover data with high‐resolution photogrammetry and field measurements, we show that juniper growth depends on topography, solar exposure and competition with shrubs. High irradiance increases biomass in older stands but limits young ones,
