This study isolated a novel halotolerant Pseudomonas aeruginosa M4, that was able to degrade oil and produce rhamnolipids. Various carbon sources, nitrogen inoculum ratio, pH, temperature were tested optimize the degradation conditions. The highest rate of 85.20% lipase activity 23.86 U/mL obtained under optimal conditions (5% at 35 °C pH 8). components products different times analyzed explore...

Abstract Various human activities have led to multiple contamination of natural water systems. The present study investigated the effect a novel multifunctional biochar treat nutrients, oil, and harmful algae in water. Specifically, magnesium (Mg) biosurfactant rhamnolipid (RL) were incorporated into biochar, including Mg-biochar, RL-biochar, Mg-RL-biochar. Their adsorption efficiency on phosph...
