This article applies findings from the recent national review of South African doctoral qualifications to examine ways in which universities interpret the formulation of, and apply in the context of a differentiated higher ...

AIMS : To assess the impact of winery wastewater (WW) on biological sand filter (BSF) bacterial community structures, and to evaluate whether BSFs can constitute alternative and valuable treatment- processes to remediate ...

2,6-Dimethoxyphenol is a phenolic compound that is extensively used for the measurement of laccase activity, but is often not exploited for its potential as an antioxidant compound. Since laccase can be used to modify ...

The paper focuses on the iterative relationship between planning and review, and the use of performance indicators in annual cycles of research review and realignment. In a large, complex institution such as the University ...

Immobilised enzyme-catalysed conversions frequently provide specific advantages of selectivity overchemical conversions and further, facilitate continuous operation through biocatalyst retention andreuse. This study focuses ...

The extracellular peroxidase from Streptomyces albidoflavus BSII#1 was purified to near homogeneity using sequential steps of acid and acetone precipitation, followed by ultrafiltration. The purified peroxidase was ...

In this study, three biological sand filter (BSF) were contaminated with a synthetic iron- [1500 mg L⁻¹ Fe(II), 500 mg L⁻¹ Fe(III)] and sulphate-rich (6000 mg L⁻¹ SO₄²⁻) acid mine drainage (AMD) (pH = 2), for 24 days, to ...

This study explored technologies for recovering energy from wastewater through production of biomass, combustion and gasification, generation of biogas, production of bioethanol, heat recovery and microbial fuel cells. A ...
