Intact Recombinant Cells of the Yeast Hansenula Polymorpha, Over-Producing Formaldehyde Dehydrogenase, as the Sensitive Bioelements for Amperometric Assay of Formaldehyde

A Reagentless Amperometric Formaldehyde-Selective Chemosensor Based on Platinized Gold Electrodes

“…FA-selective biosensors are based on cells [18] or enzymes, such as alcohol oxidase (AOX) or formaldehyde dehydrogenase (FdDH), which are used as biorecognition elements [19,20,21,22,23,24,25]. Potentiometric biosensors consisting of a pH-sensitive field effect transistor as a transducer, and containing either the enzyme AOX or permeabilized yeast cells, have been described by Korpan et al [21].…”

“…A number of attempts to develop biosensors for the detection of FA were reported, including amperometric sensors [ 17 , 18 , 19 , 20 ] and potentiometric detection schemes [ 21 ]. FA-selective biosensors are based on cells [ 18 ] or enzymes, such as alcohol oxidase (AOX) or formaldehyde dehydrogenase (FdDH), which are used as biorecognition elements [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ]. Potentiometric biosensors consisting of a pH-sensitive field effect transistor as a transducer, and containing either the enzyme AOX or permeabilized yeast cells, have been described by Korpan et al [ 21 ].…”

Alcohol oxidase- and formaldehyde dehydrogenase-based enzymatic methods for formaldehyde assay in fish food products

“…Recent achievements in the field of FA analysis include enzymatic and biosensor approaches based on the use of bacterial or yeast recombinant formaldehyde dehydrogenase (Ali et al, 2006;Ali et al, 2007;Demkiv, Paryzhak, Gayda, Sibirny, & Gonchar, 2007;Demkiv et al, 2008;Ho & Richards, 1990;Nikitina et al, 2007;Paryzhak, Demkiv, Schuhmann, & Gonchar, 2008) and yeast alcohol oxidase which is able to oxidise FA (Dmytruk et al, 2007;Gonchar, Strzelczyk, Maidan, Bień , & Sibirny, 1998;Sibirny et al, 2008).…”
