Degrading Tire Rubber: Could Isolation of Filamentous Fungi Work?
Author(s): Salomé Gómez-Gómez, Luis David Gómez-Méndez* and Angela María Alvarado-Fernández
Tire Rubber (TR) is a material that despite being recalcitrant can be biodegraded. Biodegradation is more
effective after detoxification, and includes biodeterioration, depolymerization, and assimilation of the material by
microorganisms. The potential for TR biodegradation in filamentous fungi isolated from deteriorated tires was
explored. Its growth was evaluated on Radha agar with ground tire rubber (GTR) at concentrations (w/v) of 0.6,
1.5, 15, 45, 100% and in liquid media at 0.8%. The best growth was obtained at the 15% concentration, possibly
due to a balance between the carbon source and the toxicity of the material. Six morphotypes grew significantly at
the 100% concentration, and four significantly acidified the liquid media, suggesting the ability to solubilize metals.
These ten (10) morphotypes that showed biodeterioration potential by growing on the po.. View More»
