Generation of clonal microplants and hairy root cultures of the aromatic medicinal plant Salvia runcinata L.f.
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: Bacterial and fungal pathogens have developed numerous defence mechanisms against antimicrobial chemical agents, and resistance to old and new produced drugs are on the rise. Discovery of natural products ...
Screening, isolating and characterizing acetyl xylan esterase enzymes from a novel ecological niche
(Stellenbosch : Stellenbosch University, 2015-03)
ENGLISH ABSTRACT: Hemicellulose, a plant cell wall polysaccharide composed amongst other 6-carbon sugars of xylose, a 5-carbon fermentable sugar, has various side-chains which hinder breakdown by the hydrolytic enzyme ...
Development of gene-linked molecular markers in South African abalone (Haliotis midae) using an in silico mining approach
(Stellenbosch : University of Stellenbosch, 2010-03)
ENGLISH ABSTRACT: The South African abalone, Haliotis midae, is the only endemic species of commercial value. Aquaculture remains the only avenue for expanding the industry, since the closure of the fishery. The current ...
