Biocatalytic resolution of substituted styrene oxides
(Potchefstroom University for Christian Higher Education, 2001)Stereochemistry and chirality are arguably two of the most important subjects pertaining to the development of new pharmaceutical drugs. Since enantiomers have the potential to encompass different pharmacological effects ... -
Biochemical analyses of deficiencies in the oxidative phosphorylation system in human muscle
(North-West University, 2007)MitochondriaI disorders are caused by biochemical abnormalities of the mitochondrial respiratory chain (RC), a key component of oxidative phosphorilation (OXPHOS). The diagnosis of a RC deficiency can be invasive, expensive, ... -
Biochemical and Structural Characterization of the Adenylyl Cyclase Activity of a Fusion Epsin N-terminal Homology Protein from Arabidopsis thaliana
(North-West University (South Africa), 2020)Adenylate cyclases (ACs) are enzymes that are known to produce 3',5'-cyclic adenosine monophosphate (cAMP) from 5'-adenosine triphosphate (ATP) as a result of some associated extracellular stimulations. However, the ... -
A biochemical estimation of efficient energy expenditure during the performance or arduous manual efforts

Die biochemiese basis van die gebruik van orotiensuur in die diagnose van aangebore metaboliese defekte
(North-West University, 2005)Metabolic screening tests like the ferrichloride- and Benedict tests are commonly used as screening tests for inborn errors of the phenylalanine and carbohydrate metabolic pathways. Just so the excretion of orotic acid ... -
'n Biochemiese benadering tot die identifisering van peroksisomale defekte
(North-West University, 2005)Peroxisomes have an indispensable role in cellular metabolism (Wanders et al, 2001). Peroxisomal disorders are characterized by abnormal pathogenesis (Moser, 1999), and metabolically by accumulation of very long chain fatty ... -
Biochemiese veranderinge in die hartspierweefsel van skape met gousiekte onder lede
(North-West University (South Africa), 1978)Gousiekte is a congestive type of cardiomyopathy which occurs among ruminants. Post mortem analysis perfonned in this investigation•;on hearts from animals suffering from gousiekte have shown that this cardiomyopathy is ... -
Biocide resistant and antibiotic cross-resistant potential pathogens from sewage and river water from a wastewater treatment facility in the North-West, Potchefstroom, South Africa
(IWA Publishing, 2019)Exposure to antibiotics, biocides, chemical preservatives, and heavy metals in different settings such as wastewater treatment plants (WWTPs) may apply selective pressure resulting in the enrichment of multiple resistant, ... -
Biocompositional and thermodecompositional analysis of South African agro-waste corncob and husk towards production of biocommodities
(Wiley, 2017)Biocompositional and thermodecompositional analyses of locally abundant agro-wastes of South African corn were evaluated for their potential utilization as biocommodities via thermochemical and bioconversion processing. ... -
Biocultural diversity of herpetofauna in South Africa : State and relevance as a science-based policy tool for conservation and social inclusion
(North-West University (South Africa), 2022)The world’s regions of high biodiversity in general also have high cultural or linguistic diversity. Researchers noticed this coincidence and started to question whether the connection between the two diversities extended ... -
Biodiesel production from a butter factory effluent
(North-West University, 2012)The production of biodiesel from a butter factory effluent was the main focus of the study. The alkali transesterification reaction was used to produce the biodiesel. The effect of the temperature, alcohol to oil molar ... -
Biodiesel production from municipal waste using lipase catalysis
(North-West University (South Africa)., 2022)Municipal solid waste (MSW) and sewage sludge are attractive feedstocks for biofuel production through hydrothermal liquefaction (HTL) due to high moisture content, availability, and low costs. HTL has the advantage of not ... -
Biodiesel production from plant oils of African origin
(North-West University, 2018)As the search for alternative sources of energy to supplement traditional fossil-derived energy has intensified across the globe, biodiesel derived from biolipids has emerged as a promising alternative to diesel fuel. This ... -
Biodiesel production from sunflower oil using microwave assisted transesterification
(North-West University, 2013)Biofuels are becoming more attractive worldwide because of the high energy demands and the fossil fuel resources that are being depleted. Biodiesel is one of the most attractive alternative energy sources to ... -
