The utilisation of bacterial species diversity as a bioindicator for biocide efficacy in water systems
(Stellenbosch : Stellenbosh University, 2019-04)ENGLISH ABSTRACT: The poor quality of cooling water, utilised by South African power plants, necessitates the use of biocides and bio dispersants to manage microbiological fouling. The two most common biocides used are ... -
Utilising Grape Pomace for Ethanol Production
(South African Society for Enology and Viticulture, 2002)Chemical analyses of grape pomace revealed the presence of significant amounts of fermentable sugars that are retained in the pomace after pressing of the grapes. Furthermore, treatment of the pomace with purified hydrolases ... -
