Characterization and identification of microbial communities in pigeon droppings using Culture-Independent techniques

Leareng, Samuel Keeng (2015-08)

Pigeon droppings, found in abundance in most cities and towns where pigeons are found, are a source of potential yeast and molds into the environment. Invasive fungal infections are a cause of morbidity and often mortality ...
Co-production of inulinase by Kluyveromyces marxianus and Saccharomyces cerevisiae in solid state fermentation

Molefe, Nnana Mantsopa (2014-02)

Solid-state fermentation (SFF) has emerged as a good method for the production of microbial enzymes such as inulinases. The use of low-cost agricultural plants and agro-industrial residues as substrates in SSF processes ...
Cobalt and cadmium chalcogenide nanomaterials from complexes based on thiourea, urea and their alkyl derivatives : synthesis and characterization

Morifi, E. L. (2015)

Cadmium and cobalt complexes of urea and thiourea were synthesized using ethanol as a solvent. All complexes were refluxed at 70 - 80 °C, left to cool at room temperature, washed with methanol and acetone to remove impurities ...
The cognitive impact of the implementation of an entry level certificate in information technology

Van Staden, Corne Johandia (2013-07-18)

Research has found that learners find it difficult to solve programming problems in a logical way, therefore the failure rate in Programming I is high. The Entry-level Certificate in Information Technology was introduced ...
