The increased use of engineered nanomaterials (ENMs) in commercial products and the
continuous development of novel applications, is leading to increased intentional and …

Biogenic formation of nano-sized particles composed of various materials (in particular,
selenium) by live microorganisms is widespread in nature. This phenomenon has been …

To date, comparatively little is known about the role of natural Fe (II)-bearing minerals in
bioremediation of chromium (VI) contaminated aquifers subject to chemoautotrophic …

Background Biofilms in sulfide-rich springs present intricate microbial communities that play
pivotal roles in biogeochemical cycling. We studied chemoautotrophically based biofilms …

Selenium (Se) deficiency and toxicity affect over a billion people worldwide. Plants can
mitigate both problems, via Se biofortification and phytoremediation. Here we explore the …

The co-occurrence of toxic vanadium (V) and chromium (VI) in groundwater receives
incremental attention while knowledge on their interactions in biogeochemical processes is …

Arsenic and barium are ubiquitous environmental toxins that accumulate in higher trophic-
level organisms. Whereas metazoans have detoxifying organs to cope with toxic metals …

Cardamine violifolia (family Brassicaceae) is the first discovered selenium hyperaccumulator
from the genus Cardamine with unique properties in terms of selenium accumulation, ie …

Microbial processes are known to mediate selenium (Se) oxidation–reduction reactions,
strongly influencing Se speciation, bioavailability, and transport throughout the environment …

Biofilms, which are aggregates of microorganisms and extracellular matrices, widely
colonize natural water bodies, wastewater treatment systems, and body tissues, and have …
