Author:Wolfaardt, F; Taljaard, JL; Jacobs, A; Male, JR; Rabie, CJDate:Oct 2004Wood-inhabiting Basidiomycetes have been screened for various applications in the pulp and paper industry and it is evident that different fungi need to be used to suit the specific requirements of each application. This study assessed the ...Read more
Author:Brady, D; Beeton, A; Zeevaart, J; Kgaje, C; Van Rantwijk, F; Sheldon, RADate:Mar 2004Bio-catalytic transformations converting aromatic and arylaliphatic nitriles into the analogous related amide or acid were investigated.These studies included synthesis of the beta-substituted nitrile 3-hydroxy-3-phenylpropionitrile, subsequent ...Read more
Author:Louw, M; Reid, SJ; Watson, TGDate:Jan 1993A Bacillus brevis gene coding for an endo-(1, 3-1, 4)-beta-glucanase was cloned in Escherichia coli and sequenced. The open reading frame contains a sequence of 759 nucleotides encoding a polypeptide of 252 amino acid residues. The amino acid ...Read more
Author:Louw, M; Reid, SJ; James, DM; Watson, TGDate:Oct 1994The sacU region from an alkalophilic Bacillus brevis was cloned and sequenced. The two open reading frames of the degS-degU operon encode polypeptides that gave calculated molecular masses of 43.8 kDa and 27.0 kDa, respectively. Sequence ...Read more
Author:Steenkamp, Lucia H; Brady, DDate:Jun 2010The non-steroidal anti-inflammatory drug naproxen is most effective as the single S-naproxen enantiomer. However, typical synthetic routes to naproxen yield the racemate of both the R and the S stereoisomers. Biocatalysts can be used to resolve ...Read more
Author:Maila, MP; Cloete, TEDate:2002The sensitivity of Lepidium sativum germination to polycyclic aromatic hydrocarbons (PAHs) was investigated in soil(s) artificially and historically contaminated with mixtures of PAR The level of germination of L. sativum decreased with ...Read more
Author:Byaruhanga, YB; Bester, BH; Watson, TGDate:Jun 1999The growth and survival of B. cereus, a known pathogen commonly found in cereals, during lactic acid fermentation of mageu, a sour maize beverage, was studied. In the mageu base inoculated with both the starter culture and B. cereus, the ...Read more
Author:Brady, D; Steenkamp, Lucia H; Skein, E; Chaplin, JA; Reddy, SDate:04 Mar 2004In a biocatalytic reaction the immobilized lipase ChiroCLEC-CR enantioselectively hydrolysed a naproxen ethyl ester racemate, yielding (S)-naproxen with an enantiomeric excess of more than 98%, an enantiomeric ratio (E) of more than 100, and ...Read more
Author:Moolman, FS; Rolfes, H; Van der Merwe, SW; Focke, WWDate:29 Jul 2004The oxygen carrying performance of a perfluorooctyl bromide (PFOB) emulsion is considered. The intended purpose is to enhance hepatocyte growth and function in a bio-artificial liver support system (BALSS). Such oxygen carrying emulsions have ...Read more
