Isolation of active coagulant protein from the seeds of Strychnos potatorum - a potential water treatment agent.

The application of natural coagulants for decentralized water treatment is gaining importance as a part of global sustainable initiative. This study focuses on the isolation of active coagulation components responsible for water clarification with respect to Strychnos potatorum seeds. The active coagulant components, protein and polysaccharide, were successfully isolated, dialysed and subjected to gel permeation chromatography.
