Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

Parasites at the Summit: Unexpected Geographic Distribution of the Blood Parasite Lineage Found in the Endangered Giant Lizard of Tenerife

open access: yesIntegrative Zoology, EarlyView.
We combined microscopic screening and molecular phylogenetic analyses to characterize blood parasites infecting Gallotia intermedia from the coastal cliffs of Montaña de Guaza and to place these infections in a broader biogeographic context. We detected apicomplexan parasites of the genus Karyolysus infecting 53.6% of G.

Brillouin–Raman micro‐mapping of silicone‐hydrogel contact lenses: Revealing chemical and mechanical heterogeneities

open access: yesJournal of Microscopy, EarlyView.
Abstract Joint Brillouin–Raman micro‐spectroscopy (BRMS) enables simultaneous, non‐destructive characterisation of the mechanical and chemical properties of soft materials at the micrometre scale, combining GHz‐range viscoelastic information from acoustic modes with the vibrational fingerprint of molecular species.
