Increasing energy demands require improved methods for enhanced oil recovery (EOR). Chemical EOR methods are most promising for maximum oil recovery, but, so far, limited due to high costs of chemicals and environmental concerns. Therefore, there is a huge interest in optimizing procedures for chemical EOR that minimize the amount of chemicals needed and rely on natural compounds, thus decreasi...

Abstract CotA laccase was successfully expressed from Pichia pastoris . Magnetic reduced graphene oxide (MRGO) nanocomposite synthesized and functionalized with iminodiacetic acid (IDA-NH 2 ), then chelated Cu 2+ for effective immobilization His-tagged laccase. The -chelated MRGO (MRGO-IDA-Cu ) showed 175 mg/g-support adsorption capacity. of MRGO-IDA-Cu nano-hybrid composite confirmed by Raman ...
