Spongin, a modified type ofcollagenprotein, forms the fibrousskeleton of most organisms among the phylumPorifera, the sponges. It is secreted by sponge cells known as spongocytes.[1]
Spongin gives a sponge its flexibility. True spongin is found only in members of the classDemospongiae.[2]
Research directions
editUse in the removal of phenolic compounds from wastewater
editResearchers have found spongin to be useful in thephotocatalytic degradation and removal ofbisphenols (such asBPA) in wastewater. A heterogeneous catalyst consisting of a spongin scaffold for ironphthalocyanine (SFe) in conjunction withperoxide andUV radiation has been shown to remove phenolic wastes more quickly and efficiently than conventional methods.[3] Other research using spongin scaffolds for the immobilization ofTrametes versicolorLaccase has shown similar results in phenol degradation.[4]
