Effect of sulfide concentration on autotrophic denitrification from nitrate and nitrite in vertical fixed-bed reactors
(ELSEVIER SCI LTDOXFORD, 2012)
Autotrophic denitrification coupled with sulfide oxidation represents an interesting alternative for the simultaneous removal of nitrate/nitrite and sulfide from wastewaters. The applicability of such bioprocess is especially ...
Characterization and kinetics of sulfide-oxidizing autotrophic denitrification in batch reactors containing suspended and immobilized cells
(IWA PUBLISHING, 2011)
Sulfide-oxidizing autotrophic denitrification is an advantageous alternative over heterotrophic denitrification, and may have potential for nitrogen removal of low-strength wastewaters, such as anaerobically pre-treated ...
Determination of the intrinsic kinetic parameters of sulfide-oxidizing autotrophic denitrification in differential reactors containing immobilized biomass
(ELSEVIER SCI LTDOXFORD, 2012)
Nitrogen removal coupled with sulfide oxidation has potential for the treatment of effluents from anaerobic reactors because they contain sulfide, which can be used as an endogenous electron donor for denitrification. This ...
Influence of Light Stress on the Accumulation of Xanthophylls and Lipids in Haematococcus pluvialis CCALA 1081 Grown under Autotrophic or Mixotrophic Conditions
(OMMEGA Publishers, 2018-04-04)
The influence of light stress and trophic environmental conditions on the production of astaxanthin, other xanthophylls and lipids from an Argentinian strain of Haematococcus pluvialis was investigated. Microalgae cultures ...
Predicting Accumulation of Intermediate Compounds in Nitrification and Autotrophic Denitrification Processes: A Chemical Approach.
Nitrification and sulfur-based autotrophic denitrification processes can be used to remove ammonia from wastewater in an economical way. However, under certain operational conditions, these processes accumulate intermediate ...
Responses to sublethal copper exposure in two strains of Chlamydomonas reinhardtii (Volvocales, Chlorophyceae) in autotrophic and mixotrophic conditions
(Int Phycological Soc, 2011-01)
The aim of this work was to determine the responses to sublethal copper exposure (20 and 40 mM CuCl) in two Chlamydomonas reinhardtii strains: the wild type 4A+and the pleiotropic mutant cur9, originally selected as a ...
Enhancement of astaxanthin production from Haematococcus pluvialis under autotrophic growth conditions by a sequential stress strategy
(Taylor & Francis, 2018-07)
The study of microalgal culture has been growing in recent decades, because the cellular structure of microalgae has diverse highly valuable metabolites that have attract attention of numerous companies and research groups. ...
Enrichment of Autotrophic Denitrifiers From Anaerobic Sludge Using Sulfurous Electron Donors
(2021-06-07)
This study compared the rates and microbial community development in batch bioassays on autotrophic denitrification using elemental sulfur (S0), pyrite (FeS2), thiosulfate (S2O32–), and sulfide (S2–) as electron donor. The ...
