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

Polymer 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 ...

Simulating Arctic Greening: Microbial Responses in Thawing Yedoma Permafrost

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Arctic permafrost soils and sediments store vast amounts of organic carbon. With global warming intensifying, these soils are increasingly exposed to microbial decomposition. Further, Arctic warming and longer growing seasons drive regional greening, potentially accelerating the degradation of the previously frozen organic matter through ...

An interdisciplinary review of the interplay of conflict, socio‐economic factors, and land cover and vegetation dynamics in Colombia

PLANTS, PEOPLE, PLANET, EarlyView.
Colombia's forests play a crucial role in preserving biodiversity and mitigating climate change, but they are currently facing severe degradation, particularly after the 2016 Peace Agreement. Our literature review highlights a growing research interest in this topic and demonstrates how interdisciplinary approaches combining diverse methods can enhance

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

PLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Challenges and limitations of introducing pigeonpea as a new crop into smallholder farming systems through farmer‐to‐farmer education in Zambia

PLANTS, PEOPLE, PLANET, EarlyView.
Legume plants offer generous benefits for both the planet and people by supporting sustainable farming, food and feed systems through their ability to symbiotically fix atmospheric nitrogen. While grain legumes are cultivated and consumed globally, their adoption, market development, and integration into cropping systems vary.
