Spongin

Spongin, a modified type of collagen protein, forms the fibrous skeleton of most organisms among the phylum Porifera, 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 class Demospongiae.[2]

Research directions

Use in the removal of phenolic compounds from wastewater

Researchers have found spongin to be useful in the photocatalytic degradation and removal of bisphenols (such as BPA) in wastewater. A heterogeneous catalyst consisting of a spongin scaffold for iron phthalocyanine (SFe) in conjunction with peroxide and UV radiation has been shown to remove phenolic wastes more quickly and efficiently than conventional methods.[3] Other research using spongin scaffolds for the immobilization of Trametes versicolor Laccase has shown similar results in phenol degradation.[4]

gollark: Or just general coloring.
gollark: I think there's a rust library for 256 color or whatever.
gollark: I don't know how that happened.
gollark: Also, it then proceeded to stop my shell prompt running, because that calls out to external processes too.
gollark: `thread 'main' panicked at 'Could not spawn the process.: Os { code: 1, kind: PermissionDenied, message: "Operation not permitted" }'` after a lot of tput runs.
