- ... The development of new biotechnology methods can solve public concerns especially on global warming and environmental pollution. This can be achieved by using integrated biorefinery bioprocesses to introduce biomass as a very best renewable source, to replace petroleum and to develop new bio-based products in an industrial scale. Genetic engineering of organisms and improving bioreactors is curren ...

- ... The main objective of this study was to investigate the efficiency of biological treatment of azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafiltration. The performance of the system was quantified by measuring the chemical oxygen demand and azo dye concentration. The biodegradation was carried out under combined alternating anaerobic and aerobic conditions ...
