Bioconversion of airborne formaldehyde by immobilized formaldehyde dehydrogenase from the recombinant methylotrophic yeast Hansenula polymorpha
نویسندگان
چکیده
Formaldehyde (FA) is a very toxic pollutant. FA in indoor air has a negative effect on human health and should be removed by ventilation or by conversion to non-toxic products. The formaldehyde dehydrogenase (FdDH), a NADand glutathione-dependent enzyme from recombinant methylotrophic yeast Hansenula polymorpha, was tested for its ability to oxidize airborne FA. A continuous fluidized bed bioreactor was designed to enable a bioconversion of airborne FA by FdDH or by recombinant yeast cells immobilized in calcium alginate beads. The results demonstrated that such the bioreactor with immobilized FdDH provides 97-100% elimination of airborne FA and the bioreactor with immobilized cells eliminates 94-100% of

Bioconversion of Airborne Methylamine by Immobilized Recombinant Amine Oxidase from the Thermotolerant Yeast Hansenula polymorpha
Aliphatic amines, including methylamine, are air-pollutants, due to their intensive use in industry and the natural degradation of proteins, amino acids, and other nitrogen-containing compounds in biological samples. It is necessary to develop systems for removal of methylamine from the air, since airborne methylamine has a negative effect on human health. The primary amine oxidase (primary ami...
متن کاملMolecular characterization of the Hansenula polymorpha FLD1 gene encoding formaldehyde dehydrogenase.
Glutathione-dependent formaldehyde dehydrogenase (FLD) is a key enzyme required forthe catabolism of methanol as a carbon source and certain primary amines, such as methylamine as nitrogen sources in methylotrophic yeasts. Here we describe the molecular characterization of the FLD1 gene from the yeast Hansenula polymorpha. Unlike the recently described Pichia pastoris homologue, the H. polymorp...
متن کاملComparison of biochemical properties of recombinant phytase expression in the favorable methylotrophic platforms of Pichia pastoris and Hansenula polymorpha
Phytic acid is the dominant form of phosphorous in plant seeds. However, phytic acid cannot beutilized by animals and causes them serious phosphate deficiency. Utilization of phytase as ananimal feed additive can affect liberation of phosphor and its mineral availability. In this study,heterologous expression of the A. niger phyA gene was investigated in the methylotrophic yeastsP. pastoris and...
متن کاملComparison of biochemical properties of recombinant endoglucanase II of Trichoderma reesei in methylotrophic yeasts, Pichia pastoris and Hansenula polymorpha
Bioconversion of cellulosic material into bioethanol needs cellulase complex enzymesthat contain endoglucanase, exoglucanase and beta glucosidase. One of the most important organisms that produce cellulases is the filamentous fungi, Trichoderma reesei which able to secrete large amounts of different cellulases. These enzymes are probably the most widely used cellulases industrially, however, th...

A yeast isolate revealing unique enzymatic activities and substrate-dependent polymorphism was obtained from autochthonous microflora of soil heavily polluted with oily slurries. By means of standard yeast identification procedures the strain was identified as Trichosporon cutaneum. Further molecular PCR product analyses of ribosomal DNA confirmed the identity of the isolate with the genus Tric...
