Sulfate pollution: evidence for electrochemical production of persulfate by oxidizing sulfate released by the surfactant sodium dodecyl sulfate
(2018-06-01)
There is increasing concern about contamination by surfactants that are used to extract organic pollutants during remediation of polluted soils and aquifers. For instance, the surfactant sodium dodecyl sulfate may produce ...
Integrated sulfate reduction and biosorption process for the treatment of mine drainages
(Trans Tech, 2017)
Sulfate is a pollutant present in the mining waste water and acid mine drainage. High levels of sulfate can generate important environmental problems. One of the alternatives proposed for the treatment of water with high ...
Design of a bioprocess for metal and sulfate removal from acid mine drainage
(Elsevier B.V., 2018)
© 2018 The high levels of sulfate and the metals in acid mine drainages generate important environmental problems. This paper describes the synergistic combination of a biosorption process and a new sulfate removal process. ...
A Kinetic Analysis of Microbial Sulfate Reduction in an Upflow Packed-Bed Anaerobic Bioreactor
(Brasil, 2012)
The effects of initial sulfate concentration on anaerobic sulfate reduction and sulfide generation kinetics were investigated in an up-flow bioreactor, using a consortium of sulfate-reducing bacteria (SRB) from water ...
Galactosaminoglycans from normal myometrium and leiomyoma
(Associação Brasileira de Divulgação Científica, 2001-05-01)
In many tumors, the amount of chondroitin sulfate in the extracellular matrix has been shown to be elevated when compared to the corresponding normal tissue. Nevertheless, the degree of chondroitin sulfate increase varies ...
Anaerobic treatment of sulfate-rich wastewater in an anaerobic sequential batch reactor (AnSBR) using butanol as the carbon source
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Biological sulfate reduction was studied in a laboratory-scale anaerobic sequential batch reactor (14 L) containing mineral coal for biomass attachment. The reactor was fed industrial wastewater with increasingly high ...
POSSIBLE ROLE for CHONDROITIN SULFATE in UROLITHIASIS - INVIVO STUDIES in AN EXPERIMENTAL-MODEL
(Elsevier B.V., 1992-06-15)
The effect of chondroitin sulfate upon the growth of calcium oxalate crystals was measured in vivo by using an experimental model in rats. Adult male Wistar rats were treated by cronical i.p. injections of chondroitin ...
Effects of sulfated and non-sulfated β-glucan extracted from Agaricus brasiliensis in breast adenocarcinoma cells – MCF-7
(2015)
The β-glucans (β-G) are polysaccharides produced by various organisms, and sulfation of β-G renders them more soluble. With the objective to assess the effects of sulfated and non-sulfated β-G extracted from Agaricus ...
The treatment of sulfate-rich wastewater using an anaerobic sequencing batch biofilm pilot-scale reactor
(ELSEVIER SCIENCE BV, 2009)
This paper presents the results from 92 cycles of an anaerobic sequencing batch biofilm reactor containing biomass immobilized on inert support (mineral coal) applied for the treatment of an industrial wastewater containing ...
Heparan sulfate and control of endothelial cell proliferation: increased synthesis during the S phase of the cell cycle and inhibition of thymidine incorporation induced by ortho-nitrophenyl-beta-D-xylose
(Elsevier B.V., 2004-08-04)
The effect of xylosides on the synthesis of [S-35]-sulfated glycosaminoglycans by endothelial cells in culture was investigated. Orthonitrophenyl-beta-D-xylose (10(-3)M) produces a dramatic enhancement on the synthesis of ...
