Biotransformation and detoxification of reactive black dye by Ganoderma tsugae

In this study, the decolourization potential of the white-rot fungus Ganoderma tsugae, which is capable of producing laccase was investigated to degrade reactive black dye. Biodegradation of reactive black dye was analyzed by using spectrophotometer at an absorbance of 585 nm. Laccase, manganese peroxidase and pH were served as biodegradation indices. Fourier transform infrared (FTIR) and gas chromatography mass...

Screening of hydrocarbon degrading fungi in crude oil polluted soil isolated in the Niger Delta

Bioremediation has been argued to be cheaper and more environmental friendly when compared to other remediation technology. Bioremediation make use of the ability of bacteria and fungi to biodegrade organic compound to cleanup hydrocarbon pollution. Many fungi have been shown to biodegrade simple and complex polycyclic aromatic hydrocarbon. In this study, petroleum hydrocarbon degrading fungi have been isolated and...

Technical evaluation of soil and water conservation measures in Maego Watershed, North Ethiopia

Soil and water conservation (SWC) practices have been carried out to solve land degradation problems in Ethiopia since the last 3 decades. Technical evaluation of the implemented SWC structures is essential for effectiveness and sustainability of the measures. Therefore, the objective of this study was to identify and evaluate the technical quality of constructed physical SWC structures in Maego watershed, Ethiopia. The...

Determination of cadmium, chromium and lead in four brands of herbal bitters preparation sold in Benin- city, Southern Nigeria

This study evaluated the level of three toxic heavy metals (cadmium, chromium and lead) in four selected brands of herbal bitter preparations sold in Benin City, Southern Nigeria purchased from chemists' shops, using the flame atomic absorption spectrophotometric technique. The result of the atomic absorption spectroscopy (AAS) analysis showed that Chromium (Cr) was not detected in any of the four brands. Lead (Pb)...
