Abstract:

A luminescence based marker system was developed for detection of genetically modified Pseudomonas fluorescens and E. coli. During batch growth in liquid culture, luminescence measured by luminometry was directly proportional to biomass concentration and enabled detection of 104 - 106 cells ml-1 of P. fluorescens and 101 cells ml-1 of E. coli, in actively growing cultures. Following inoculation into soil, detection levels were reduced ten-fold. After the subsequent utilisation of available nutrients, activity and luminescence decreased and luminometry then provided a direct, non-extractive mea

Abstract:

The concept behind this project was to continue the development of strains of Agrobacterium tumefaciens that were capable of producing pesticidal proteins in response to plant wounding, thereby killing the invading organism. To this end, vir induction was studied in A. tumefaciens and a protocol to elicit the maximum response was developed. In order for this concept to work, it was necessary to determine whether vir induction was occurring at plant wound sites and a method for showing this was developed, the results suggesting that indeed vir induction did occur.

Abstract:

With shifting preferences of consumers towards healthier food, organic food demand has been on the rise for the past two decades. This increased demand has created an opportunity for farmers to shift from conventional to organic production. However, there are risks and uncertainties associated with organic farming. The management of an organic farm in the absence of organic-based disease and pest suppressing strategies constrains farmers from adopting organic vegetable production. The use of cover crops to control soil-borne diseases and suppress weeds and other pests has increased because of

Thesis (MSc Food Sc)--Stellenbosch University, 2002.<br>ENGLISH ABSTRACT: The start-up period of Upflow Anaerobic Sludge Bed (UASB) reactors can significantly be reduced by enhancing the time-consuming granulation process through the batch cultivation of anaerobic granular sludge and thus seeding the reactor with this cultivated granular sludge, instead of raw anaerobic sludge. The precise mechanism for granule formation is not well known, but it is believed that extracellular polymers (ECP) play a critical role in the granulation process.

Abstract:

The use of silage additives can improve the reliability of the ensilage process. The fact that chemical additives are both highly corrosive to expensive farm machinery and hazardous to handle has prompted the development of alternative silage additives. Bacterial inoculants were developed to provide a source of homofermentative lactic acid bacteria. The objective of this study was to develop a bacterial silage inoculant that would improve the efficiency of ensilage of a crop. An inoculant termed SilCare II was developed.

Neste sentido, alimentos com um elevado valor nutritivo, como por exemplo as leguminosas (proteína, minerais, vitaminas e compostos bioativos) aparecem como uma resposta a esta necessidade. É, no entanto, essencial aumentar a sua produtividade. Ao mesmo tempo, é também necessário reduzir a aplicação de fertilizantes inorgânic

Abstract:

Associations between leguminous plants and symbiotic nitrogen-fixing bacteria (rhizobia) are a classic example of mutualism between a eukaryotic host and a specific group of prokaryotic microbes. Rhizobia improve plant yield furnishing fixed nitrogen; therefore, they are highly used as inoculants, especially in sustainable agriculture. Though this association is species-specific, legume roots are exposed to heterogeneous rhizobial populations where different compatible strains are present and, could be infected by more than one strain. It is known that within the same rhizobial species differe

Abstract:

Inoculation with diazotrophic bacteria is well documented as a means to enhance growth and increase yields of various crops, especially when used as an alternative or a supplement to the use of nitrogenous fertilizers and agrochemicals for sustainable agriculture. Nitrogen is the most limiting nutrient for increasing crop productivity, and the use of chemical sources of N fertilizers is expensive, and may contribute to environmental pollution. Therefore, there is a need to identify diazotrophic inoculants as an alternative or supplement to N-fertilizers for sustainable agriculture. The search
