Utilización de la κ-carragenina como soporte de inmovilización de microorganismos marinos degradadores de hidrocarburos.

Abstract

Una marea negra provocada por el vertido deliberado o accidental de crudos de petróleo, aceite combustible, fangos o residuos petrolíferos y productos refinados, provoca un gran impacto sobre los ecosistemas marinos y costeros. En este trabajo, se desarrolla un producto compuesto por bacterias marinas inmovilizadas por atrapamiento en k- carragenina semirrefinada y en cuya formulación no se incluyen nutrientes. Los resultados muestran que la variante de inmovilización más ventajosa se obtuvo cuando fue empleada la κ-carragenina al 1% gelificada con una solución de KCL 1.5 M. Mediante análisis de Cromatografía Gaseosa de Alta Resolución y de espectroscopia (FTIR), se demostró la alta capacidad de degradación del bioproducto frente a petróleo del Yacimiento de Pina.

A black tide caused by the deliberate or accidental spills of raw petroleum, combustible oil, mires or oil residuals and refined products causes a great impact on the marine and coastal ecosystems. This work present the development of a product composed of bacteria marine immobilized by entrapped in k–carrageenan. Its formulation does not included nutrients. The results show that the variant of more advantageous immobilization was obtained when using k-carrageenan at 1-% jellified with a solution of KCL 1.5M. By means analysis of High Resolution Gas Chromatography and of Spectroscopy (FTIR), the high degrading capacity of this bioproduct was demonstrated before oil from Pina oil field.
