Biodegradation of bone glue as an environment-friendly organic adhesive suitable for building materials

Popis výsledku v původním jazyce

Bone glue is a protein-based adhesive made from collagen of bones. Its formation with sodium lignosulfonate leads to strong bindings necessary for its adhesive properties. Bone glue is considered as an ecological material thanks its zero production of toxic gases into air, but its biodegradation has never been studied. For this reason, there was tested biodegradation potential of pure bone glue, pure sodium lignosulfonate and their mixture on the agar test with aerial molds under defined laboratory conditions (7 days, 28 °C, in the dark) in the present study. The results indicated that all samples were affected by molds. The degree of mold presence in the samples of glue, sulfonate and their mixtures was similar, or even higher, than in the pure, sterile control agar. This may be due to the higher amount of nutrients in the tested samples compared to the control, as bone glue is a pure natural biological material and lignosulfonate is used in agriculture as a fertilizer. In every case, a presence of bone glue influenced the mold composition species, contrary to pure lignosulfonate.
