Biocatalytic oxidation reactions offer several important benefits such as regio- and stereoselectivity, avoiding the use of toxic metal based catalysts and replacing oxidizing reagents by allowing the use of oxygen. In this contribution the oxygen requirements are analysed for different process scenarios, considering different biocatalyst formats and variation of the desired productivity. Also, the applicability of two different oxygen supply methods (bubbling and membrane aeration) is considered. The results indicate that growing cells could be used to reach productivities up to 3.5g L-1h-1 without oxygen supply being limiting. Also, membrane contactors can provide a feasible oxygen supply method when bubble-less aeration is desired. However, in order to support high productivity the oxygen flux using air may be insufficient, thus requiring the use of oxygen. © 2015 Elsevier B.V.

A controlled reaction schema for addition curing silicones leads to both significantly lower elastic modulus and lower viscous dissipation than for the chemically identical network prepared by the traditional reaction schema. © 2012 The Royal Society of Chemistry.
