Comparison of biodegradative efficiency of wildtype versus mutagenised Scenedesmus vacuolatus of spent coolant waste: dehydrogenase activity and total petroleum degradation studies

This study aims to compare the biodegradability efficiency of spent coolant waste by wild-type microalga versus mutagenised Scenedesmus vacuolatus. The biodegradation efficiency of both groups microalgae was evaluated using dehydrogenase activity (DHA) and total petroleum hydrocarbon (TPH) degradation using gas chromatography and mass spectrometry (GCMS). The DHA of both microalgae was conducted in relation to the triphenyl formazan production...
