BIOFLOCCULANT AND BIOSORBENT DERIVED FROM DEAD CELLS OF MARINE FILAMENTOUS BACTERIUM FOR HEAVY METAL AND WASTE MATERIAL REMOVAL

摘要

The present invention relates to a method of producing an article suitable for use as a bioflocculant or a biosorbent for waste material and heavy metal removal. The method preferably comprises the steps of growing cells of a marine filamentous bacterium in a culture medium to achieve a log phase of bacteria growth (100); harvesting by way of separating the said cells of marine filamentous bacterium from the culture medium (200), wherein the step of harvesting includes centrifugation; and fixing the harvested cells of marine filamentous bacterium by subjecting the same to treatment with formaldehyde (300), wherein the said article comprises the fixed cells of marine filamentous bacterium.
