Lactobionic acid. This derivative is produced by oxidation of the free carbonyl group of lactose (Figure 2.25), chemically (Pt, Pd or Bi), electro-lytically, enzymatically or by fermentation. Its lactone crystallizes readily. Lactobionic acid has found only limited application its lactone could be used as an acidogen but it is probably not cost-competitive with gluconic acid-<5-lactone. It is used in preservation solutions for organs prior to transplants.

Application and Principle This procedure is used to determine glucose oxidase activity in preparations derived from Aspergillus niger var. The assay is based on the titrimetric measurement of gluconic acid produced in the presence of excess substrate and excess air. 

Specifically, rest of this chapter begins by very briefly considering MOO in general, followed by a more detailed discussion of the algorithm of net flow and rough set methods, whilst illustrating these with simple examples. The last section of the chapter is devoted to the application of this method to the production of gluconic acid.

Proof of the location of the methoxyl group at C3 was established by application of periodate oxidation to methyl 2-acetamido-2-deoxy-3-0-methyl-a-D-glucopyranoside and to 2-amino-2-deoxy-3-0-methyl-D-gluconic acid. The first compound was resistant to oxidation, whereas the second consumed two equivalents of periodate per mole and released one mole of formaldehyde and one mole of formic acid per mole, but afforded no ammonia. ... 

One important application is in the field of carbohydrate transformations, the catalytic oxidation of D-glucose to D-gluconic acid represents an economically competitive route with respect to biochemical oxidation [4], This new process is the result of extensive studies on the selective Cl-hydroxyl group oxidation in the presence of O2 using a Pt or Pd catalyst modified with cocatalysts [5].
