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 ...

A novel lipid from the brown alga Notheia anomala

open access: yes, 1980
The brown alga Notheia anomala has yielded a C19 lipid diol, (6S,7S,9R,10R)-6,9-epoxynonadec-18-ene-7,10-diol, as the major component. The structure, assigned on the basis of spectral data, was confirmed by single-crystal X-ray analysis, which also ...

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

open access: yesPolymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Hydroazulenoid diterpenes from the brown alga dictyota dichotoma var. Implexa*1

open access: yes, 1986
Together with the previously described pachydictyol A and dictyol B acetate, a new hydroazulenoid diterpene, dictyol I acetate, was isolated from the brown alga Dictyota dichotoma var. implexa obtained from the Northern Adriatic sea. The structure of the

Tetraprenyltoluquinols from the brown alga Cystoseira jabukae

open access: yes, 1985
The chloroform extract of the brown alga Cystoseira jabukae afforded two new tetraprenyltoluquinols and two tetraprenyltoluquinones. The structures were determined by spectral analysis and chemical correlations. The quinones are possibly artifacts formed

High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.
