Influence of Surface Acidity in Lactose Oxidation Over Supported Pd Catalysts
Microporous and Mesoporous Materials, 2008Lactose oxidation to lactobionic acid was investigated over palladium forms of Beta and MCM-22 zeolites. Different support acidity and the method of palladium introduction were applied. It was observed that the catalyst preparation methods, as well as acidity, influence the activity and selectivity. Pd-H-MCM-22 zeolites were more active, than palladium

Electro-Oxidation of Lactose on Platinum and on Modified Platinum Electrodes in Alkaline Medium
Electrochimica Acta, 1994Abstract In this priliminary work, the electro-oxidation of lactose was investigated by cyclic voltammetry in alkaline medium on platinum electrodes. Tafel slopes and variation of electrochemical parameters indicated that the electrocatalytic oxidation of lactose was controlled by diffusion.

Interaction of Isoniazid with Magnesium Oxide and Lactose
Journal of Pharmaceutical Sciences, 1970Interactions of isoniazid with magnesium oxide and with lactose were investigated in the solid state. In the isoniazidmagnesium oxide system, chemisorption as well as physical adsorption of isoniazid molecules onto the magnesium oxide surface was confirmed by diffuse reflectance spectroscopic data.

Supercritical water oxidation of lactose
The Canadian Journal of Chemical Engineering, 2017AbstractNew data on total organic carbon (TOC) reduction and H2 production were obtained by using supercritical water oxidation of lactose with and without oxidant agents (H2O2 and t‐BHP) in a continuous Inconel 625 flow reactor. The oxidation reactions were carried out at 550 and 700 °C, 22.5 MPa, 0.025 g/g (2.5 wt%) lactose concentration, feed flow ...

Production and characterization of aluminium oxide nanoshells on spray dried lactose
International Journal of Pharmaceutics, 2017Atomic layer deposition (ALD) enables deposition of dense nanometer thick metal oxide nanoshells on powder particles with precise thickness control. This leads to products with low weight fraction coating, also when depositing on nano- or micron sized powder particles.

Kinetics of lactose and rhamnose oxidation over supported metal catalysts
Physical Chemistry Chemical Physics, 2011Several mono- and bimetallic Pd, Pt, Rh and Ru supported on alumina and active carbon catalysts were characterized by CO chemisorption, nitrogen adsorption, XPS and XRD and acidity titrations were performed for active carbon supported catalysts. These catalysts were tested in oxidation of two sugars, namely lactose and rhamnose, at 60 °C and at 70 °C ...

Bacterial Oxidation of Lactose and Melibiose
Nature, 1958DURING an investigation of bacteria isolated from blocks of whale meat, two distinct strains of paracolon bacteria (Blx, urease-positive; and C6, urease-negative) were obtained, the sugar metabolism of which was interesting. Tested in the normal way with Durham tubes, these organisms produced acid from lactose within 5–12 days at 30° C.

Enzyme and Microbial Technology, 2001
Abstract We report a novel and efficient way of producing lactose-derived galacto-oligosaccharides (GOS) that do not contain remaining lactose and monosaccharides. The initial sugar mixture was obtained by enzymatic transformation at 70°C of a lactose solution of 270 g/liter using recombinant β-glycosidase from the Archaeon Sulfolobus solfataricus .
