Oxygen transfer in hydrocarbon-aqueous dispersions and its applicability to alkane-based bioprocesses
(Stellenbosch : University of Stellenbosch, 2007-12)
Adequate provision of oxygen to aerobic bioprocesses is essential for the optimisation of process kinetics. In bioprocesses in which the feedstock is an alkane, the supply of sufficient oxygen is of particular concern ...
Development and evaluation of an alkane bioconversion process using genetically modified Escherichia coli
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Alkanes can be used as an inexpensive feedstock to produce more valuable alcohols. The biotransformation of alkanes to alcohols provides an alternative to conventional chemical procedures. The scope ...
The phase equilibrium of alkanes and supercritical fluids
(Stellenbosch : University of Stellenbosch, 2001-12)
Current methods for wax fractionation result in products with large polydispersity, and due to the high temperatures required, thermal degradation of the wax is often incurred. The need for an alternative process thus ...
Bioconversion of alkylbenzenes by Yarrowia lipolytica
(Stellenbosch : University of Stellenbosch, 2009-03)
The abundance of alkane by-products formed in South Africa presents a feedstock opportunity for the production of a wide range of commercially important products, such as long-chain dioic acids and alcohols. These compounds ...
