🌍Biodegradation by Algal Cultures:
🔎 Introduction: Algal cultures effectively remove substances, but there's limited research on pharmaceuticals' impact.
▶️ Algal Cultures for Nutrient and Contaminant Removal: Certain algae can break down carbamazepine, but high concentrations hinder growth.
▶️ Limited Studies on Pharmaceutical Removal: Concentration influences removal rates and inhibition.
▶️ Removal Rates of Carbamazepine: Different rates for Scenedesmus obliquus and Chlamydomonas mexicana.
▶️ Effect of Concentration on Removal and Inhibition: Higher concentrations decrease removal and increase inhibition.
▶️ Proposed Mechanisms for Carbamazepine Degradation: Potential mechanisms include epoxidation and oxidation.
▶️ Removal of Other Pharmaceuticals using Chlorella sorokiniana: Chlorella sorokiniana effectively removes various pharmaceuticals.
🌍 Biodegradation Using Biocatalysts:
🔎Introduction: Biocatalysis, including laccases, is effective for enzymatic bioremediation.
▶️B. Enzymes Used in Biocatalysis: Laccases play a crucial role, but large-scale applications face challenges.
🌍 Fungal Laccases:
🔎 Introduction: Laccases from Pycnoporus sanguineus CS43 fungi are effective biocatalysts.
▶️ Laccases from Pycnoporus sanguineus CS43 Fungi for Wastewater Bioremediation: Effective degradation of various pharmaceuticals.
▶️ Degradation of Pharmaceuticals: Laccase cocktails effectively degrade diclofenac and tricyclic antidepressants.
▶️ Influence of Functional Groups: Electron-donating groups enhance enzymatic degradation.
🌍 Immobilization Techniques:
🔎 Introduction: ▶️ Immobilizing laccases enhances effectiveness in pharmaceutical removal.
▶️ Immobilization of Laccases on Mesoporous Silica Spheres: pH influences the efficiency of diclofenac biotransformation.
