Acid dye biodegradation using saccharomyces cerevisiae immobilized with polyethyleneimine-treated sugarcane bagasse
Chemical reagents used by the textile industry are very diverse in their composition, ranging from inorganic compounds to polymeric compounds. Strong color is the most notable characteristic of textile effluents, and a ...
Immobilized and free cells of geotrichum candidum for asymmetric reduction of ketones: Stability and recyclability
Marine-derived fungus Geotrichum candidum AS 2.361 was previously reported by our group as an active strain for the enantioselective reduction of ketones. Although some other Geotrichum strains were also found from the ...
FT-IR analysis of acid black dye biodegradation using saccharomyces cerevisiae immobilized with treated sugarcane bagasse
Textile industries use large amounts of water in dyeing processes and a wide variety of synthetic dyes. A small concentration of these dyes in the environment can generate highly visible pollution and changes in aquatic ...
Clavulanic acid production by immobilized cells if Streptomyces clavuligerus
(Inst Tecnologia Parana, 2006-02-01)
A clavulanic acid production process with immobilized Streptomyces clavuligerus cells was investigated. Cells were immobilized in diatomaceous earth, calcium alginate gel as well as in the form of natural pellets and ...
Characterization of Saccharomyces cerevisiae immobilized onto chrysotile for ethanol production
(John Wiley & Sons LtdW SussexInglaterra, 1998)
Asymmetric ketone reduction by immobilized Rhodotorula mucilaginosa
In our previous study, Rhodotorula mucilaginosa (R. mucilaginosa) was selected via high throughput screening as a very active and selective whole-cell biocatalyst for the asymmetric reduction of ketones. In this study, the ...
Acid Black 48 dye biosorption using Saccharomyces cerevisiae immobilized with treated sugarcane bagasse
(I W A Publishing, 2012-01-01)
The textile industry consumes large quantities of water and chemicals, especially in dyeing and finishing processes. Textile dye adsorption can be accomplished with natural or synthetic compounds. Cell immobilization using ...
Scavenging of nickel and chromium toxicity in Aulosira fertilissima by immobilization:: Effect on nitrogen assimilating enzymes
(Pontificia Universidad Católica de Valparaíso, 2004)
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 ...
Use of sugarcane bagasse as biomaterial for cell immobilization for xylitol production
(ELSEVIER SCI LTD, 2008)
This study provides a preliminary contribution to the development of a bioprocess for the contintious production of xylitol from hemicellulosic hydrolyzate utilizing Candida guilliermondii cells immobilized onto natural ...
