Published: December 1992

A new type of flow bioreactor designed to remove nitrate from water was developed. Denitrification activity of native Paracoccus denitrificans cells was used, the cells being separated from the refined medium by a semipermeable membrane. Relationships between the degree of nitrate conversion and the denitrification rate, on the one hand, and the volume flow rate and the amount of biomass, on the other, together with the results concerning denitrification during closed-circuit recirculation of the medium are discussed.

The lactic acid bacterial (LAB) species have proven multifaceted roles in sustainable agriculture due to their biologically safe nature, making them eco-friendly. However, their plant growth-improving mechanisms in stressed and non-stressed conditions are still under consideration. Thus, the current work has been planned to evaluate the drought tolerance potential and plant growth-promoting (PGP) traits of Loigolactobacillus coryniformis BCH-4 in Zea mays L.

Synthesis of the photocatalysts with near-infrared light response usually involves upconversion materials or plasmon-assisted noble metals. Herein, NiTiO/TiO was synthesized by using waste tobacco stem-silks as biotemplates and tetra-tert-butyl orthotitanate and nickel nitrate as precursors in a one-pot procedure. NiTiO(1.

The complex pollution and nutrient-poor characteristics of surface waters result in the limited ability of conventional reactors to remove pollutants. In this study, a novel modified ceramsite material, modified with trivalent iron (Fe(III)) and fulvic acid (FA) to form ceramsite@Fe(III)@FA (HC), was used for the first time as a biocarrier to immobilize strain Cupriavidus sp. W12, constructing a biofilter to enhance nitrate (NO-N) removal in micro-polluted water.

Microbial manganese redox cycling drives co-removal of nitrate and ammonium.

State Key Laboratory of Urban Water Resource and Environment, Harbin Institute of Technology, Harbin, 150090, China. Electronic address:

Manganese (Mn), abundant in the Earth's crust, can act as an oxidant or a reductant for diverse nitrogen biotransformation processes. However, the functional microorganisms and their metabolic pathways, as well as interactions, remain largely elusive. Here, a microbial consortium was enriched from a mixture of freshwater sediments and activated sludge by feeding ammonium, nitrate and Mn(II), which established manganese-driven co-removal of nitrate and ammonium with removal rates of 5.

Biological semi-passive mine water treatment technologies are used in the mining industry as an alternative to or in conjunction with active treatment systems to remediate mine impacted water (MIW) containing nitrate and selenium oxyanions such as selenate and selenite. In semi-passive biological treatment systems, MIW is pumped through a saturated, porous media (either a gravel bed or waste rock) which provides ample surface area for biofilm growth and the creation of anoxic, subaqueous environments. Additional nutrients and carbon sources are pumped into the system to encourage the growth of microbes that biochemically reduce selenate and selenite to insoluble reduced Se species such as selenium nanoparticles (SeNP) by respiring selenate and selenite.
