Investigation of exopolysaccharide producing bacteria isolated
(Stellenbosch : Stellenbosch University, 2012-12)
ENGLISH ABSTRACT: The deterioration of harvested sugarcane as a result of bacterial growth causes
major losses of sucrose and a build-up of exopolysaccharides (EPS).
Polysaccharides present during production increase the ...
Identification of the genes encoding enzymes involved in the synthesis of the biopolymer paramylon from Euglena gracilis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Recent advances in medical pharmacology have identified the immune-potentiating effects of β-1,3-glucans on mammalian immune systems. Extensive research has identified and described the mechanisms of ...
Nitric oxide signaling and cysteine protease activity in the modulation of abiotic stress responses in soybean and maize
(Stellenbosch : University of Stellenbosch, 2010-11-24)
ABSTRACT: Nitric Oxide (NO) is an essential bioregulatory molecule in plant growth, development,
and tolerance against biotic and abiotic stresses. In legume root nodules, abiotic stresses
impose restraint on metabolic ...
An investigation into the effects of smoke-water and GR24 on the growth of nicotiana benthamiana seedlings
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Novel plant growth regulating substances (PGRs) are emerging as a useful tool to investigate important growth traits in plants. This study reports on growth promotion pathways leading to enhanced biomass ...
Identification of regulatory elements mediating responses of SOD and cystatin transcripts to salt stress and nitric oxide in soybean nodules
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: Nitric oxide (NO) has previously been shown to play a vital role in plants that are undergoing oxidative stress arising from abiotic stress. To better understand the role of NO on the antioxidative pathway, ...
Isolation and characterisation of genes encoding biopolymer manufacturing enzymes
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: Biopolymers exhibit the required material properties to replace conventional, non-biodegradable, petroleum-based polymer products. They have a closed carbon cycle, making them carbon neutral and environmentally ...
Production of libraries to study biopolymer metabolism in Arabidopsis thaliana and Tylosema esculentum
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: Biopolymers and bio-degradable polymers are of utmost importance to ensure a sustainable economy. Industry depends on raw material, which in many cases are derived from fossil fuels, but in light of looming ...
Manipulation of ascorbate biosynthesis in Solanum lycopersicum (cv Money maker)
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Vitamin C (ascorbate or AsA) is a secondary metabolite produced in many eukaryotes including yeasts, plants and animals. It plays essential roles as an anti-oxidant and enzyme cofactor, functions as an ...
Approaches for the study of leaf carbohydrate metabolic compartmentation in arabidopsis thaliana
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The study of plants on a sub-cellular level is an important, yet challenging area and its application allows for novel insight into the understanding of metabolism and its regulation. In this study I ...
Genetic engineering of sugarcane for increased sucrose and consumer acceptance
(Stellenbosch : Stellenbosch University, 2011-12)
ENGLISH ABSTRACT: Sugarcane is a crop that is farmed commercially due to the high amounts of sucrose that
is stored within the mature internodes of the stem. Numerous studies have been done to
understand sugar metabolism ...
