Xylanase production by a recombinant strain of Saccharomyces cerevisiae: the effect of carbon catabolite repression and ethanol concentration in batch and continuous cultures
(University of the Free State, 1999-09)English: Endo-β-I,4-xylanase production by a recombinant strain of Saccharomyces cerevisiae Y294, transformed with a Trichoderma reesei xylanase gene (XYN2), was evaluated in batch and continuous cultures. Expression of ... -
Yeast diversity in blue mould ripened cheeses
(University of the Free State, 2003-01)English: Blue veined cheese is considered a speciality cheese and is not as popular as other cheese varieties, such as Cheddar or Gouda. Their popularity is however increasing worldwide making it important to study their ... -
Yeast diversity in white mould-ripened cheeses
(University of the Free State, 2002-01)Surface mould-ripened cheeses represent a small proportion of world cheese production. However, these cheeses are becoming increasingly popular with the consumer, as there is an increasing demand for it (Gripon, 1987). ... -
Yeast sensors reveal chloroquine as yeast fertility drug
(University of the Free State, 2013-11)English: Previous unpublished research by Kock and co-workers indicated that the antimalarial drug chloroquine (CQ) stimulates yeast sexual stages (biosensors). Consequently several indicator yeasts (Eremothecium ashbyi, ... -
A yeast-based assay for detection of mutations in the human p16 gene
(University of the Free State, 1999-05)Cyclin-dependent kinases (CDKs) are crucial regulators of the cell cyele. CDKs themselves are subject to control by both cyelins and CDK inhibitors. Among the inhibitors, p 16 is very prominent, since it has been found ... -
Yeasts as adjunct starter cultures in cheese making
(University of the Free State, 2011-01)A literature review on the role and presence of microorganisms in cheese was reviewed. The biochemical pathways involved in the cheese manufacture from the milk to the resultant cheese curd at the end of manufacturing were ... -
Yeasts from Lesotho: their classification and possible applications
(University of the Free State, 2004-11)In view of the decline of natural habitats due to urban and industrial development, the need to search for new yeasts is pressing since few natural habitats have been thoroughly investigated for yeast species. Yeasts have ... -
