Improved production of 3-hydroxypropionaldehyde by complex formation with bisulfite during biotransformation of glycerol.
Biotechnol. Bioeng. 110(4) , 1243-8, (2013) 3-Hydroxypropionaldehyde (3HPA) is an important specialty chemical which can be produced from glycerol using resting cells of Lactobacillus reuteri. This biocatalytic route, however, suffers from substrate- and product-mediated loss of enzyme activity within ... |

Determination of free and reversibly-bound sulfite in selected foods by high-performance liquid chromatography with fluorometric detection.
J. AOAC Int. 91(1) , 98-102, (2008) A rapid and accurate method for measuring low part-per-million levels of free and reversibly-bound sulfites in selected foods by using high-performance liquid chromatography (HPLC) with fluorometric detection was developed. Sulfites were extracted with sodium... |

Light-induced formation of hydroxyl radicals in fog waters determined by an authentic fog constituent, hydroxymethanesulfonate.
Chemosphere 51(3) , 175-9, (2003) The determination of the photo-production rate of hydroxyl radical (OH) in atmospheric liquids is of fundamental importance to an understanding of atmospheric aquatic chemistry. Recently, several studies have been performed to examine the photo-chemical forma... |

Acid fog-induced bronchoconstriction. The role of hydroxymethanesulfonic acid.
Am. Rev. Respir. Dis. 141(3) , 546-51, (1990) Hydroxymethanesulfonate (HMSA), the bisulfite (HSO3-) adduct of formaldehyde (CH2O), is a common constituent of California acid fogs. HMSA, most stable in a fog pH range of 3 to 5, dissociates at 6.6, the pH of the fluid lining human airways. The dissociation... |

Determination of free and reversibly bound sulphite in foods by reverse-phase, ion-pairing high-performance liquid chromatography.
Food Addit. Contam. 7(5) , 575-81, (1990) The reaction of sulphite with formaldehyde to form hydroxymethylsulphonate (HMS), which is very stable under the controlled conditions of this assay, was used as the first step in an analytical procedure to determine foodborne sulphite. The effect of mobile-p... |
