Technologies to recover nitrogen, phosphorus, and potassium from waste streams have
undergone accelerated development in the past decade, predominantly due to a surge in …

Heavy metals affect the biochemical reactions that take place during anaerobic digestion
processes of organic matter. In this review, the different effects observed in anaerobic …

A non-parametric method for texture synthesis is proposed. The texture synthesis process
grows a new image outward from an initial seed, one pixel at a time. A Markov random field …

Preservation of the soil resources stability is of high importance for ecosystems, particularly
in the current era of environmental change, which presents a severe pollution burden (eg by …

A novel, clean biological transformation reaction by immobilized Rhodobacter sphaeroides
has been developed for the synthesis of zinc sulfide (ZnS) nanoparticles with an average …

Bioremediation with microorganisms is a promising technique for heavy metal contaminated
soil. Rhodobacter sphaeroides was previously isolated from oil field injection water and …

Metal contamination poses serious biotoxicity and bioaccumulation issues, affecting both
abiotic conditions and biological activity in ecosystem trophic levels, especially sediments …

Purple non-sulfur bacteria are anoxygenic photosynthetic microorganisms characterized by
an extremely versatile metabolism, allowing them to grow in a broad variety of conditions as …

Photosynthetic bacteria have flexible metabolisms and strong environmental adaptability,
and require cheap, but plentiful, energy supplements, which all enable their use in Cr (VI) …

The trace metal selenium is in demand for health supplements to human and animal
nutrition. We studied the reduction of selenite (SeO3− 2) to red elemental selenium by …
