Removal of Di-(2-ethylhexyl)phthalate (DEHP) from water using a LECA-Pseudomona...
Rosales, E.; Cobas, M.; Tavares, M. T.; Sanromán, M. A.; Pazos, M.The removal and biodegradation of an organic toxic pollutant, di-(2-ethylhexyl) phthalate (DEHP), has been investigated. Initially, a screening of different degrading bacteria has been developed and Pseudomonas putida showed the highest degradation ability. This bacterium was immobilised in an inert support, light expanded clay aggregate (LECA). After the biofilm formation on the LECA, the degradation of DEHP w...
Assessment of Arthrobacter viscosus as reactive medium for forming permeable re...
Ferreira, L.; Cobas, M.; Tavares, M. T.; Sanromán, M. A.; Pazos, M.Polycyclic aromatic hydrocarbons (PAHs) are significant environmental contaminants as they are present naturally as well as anthropogenically in soil, air and water. In spite of their low solubility, PAHs are spread to the environment, and they are present in surface water, industrial effluent or groundwater. Amongst all remediation technologies for treating groundwater contaminated with PAHs, the use of a perm...
Development of permeable biobarrier for the removal of PAH’s by Trichoderma lon...
Cobas, M.; Ferreira, L.; Tavares, M. T.; Sanromán, M. A.; Pazos, M.In this work, the formation of permeable reactive biobarriers (PRBBs) using Trichoderma longibrachiatum over nylon sponge as bioreactive medium for removal of polycyclic aromatic hydrocarbons (PAHs) was studied. Colony formation was pretested without PAH presence by inoculation of fungus into nylon sponge. The fungus formed a large quantity of strongly adhesive biofilm among nylon sponge. Afterwards, the abilit...
