Biorremediação de solo contaminado por isobutanol, Bis-2-etil-hexilftalato e Di-isodecilftalato

Embora os ftalatos sejam um dos poluentes mais frequentemente encontrados no meio ambiente, há escassez de dados na literatura sobre biorremediação de solos tropicais contaminados por esses compostos. Por esse motivo, este estudo avaliou a biorremediação de um solo contaminado com os plastificantes DEHP (Bis-2-etilhexilftalato), DIDP (Di-isodecilftalato) e álcool isobutílico, por uma indústria no Estado de São Paulo. A biorremediação ocorreu pela utilização de microrganismos presentes no solo e pela adição de inóculo adaptado em reator em fase de lama. O reator foi monitorado durante 120 dias, sendo corrigida apenas a umidade do solo. Os resultados indicaram que a biodegradação dos ftalatos seguiu uma cinética de primeira ordem e a biorremediação ocorreu na faixa de pH entre 7,4 e 8,4 e temperaturas entre 17 e 25 ºC, com eficiência de remoção de contaminantes acima de 70 %. Após 120 dias, o teor de DEHP estava abaixo de 4 mg kg-1, limite estipulado pela legislação brasileira para solo de uso residencial.

Aggregation of integrins and RhoA activation are required for Thy-1-induced morphological changes in astrocytes.

Thy-1, a cell adhesion molecule abundantly expressed in mammalian neurons, binds to a beta(3)-containing integrin on astrocytes and thereby stimulates the assembly of focal adhesions and stress fibers. Such events lead to morphological changes in astrocytes that resemble those occurring upon injury in the brain. Extracellular matrix proteins, typical integrin ligands, bind to integrins and promote receptor clustering as well as signal transduction events that involve small G proteins and cytoskeletal changes. Here we investigated the possibility that the cell surface protein Thy-1, when interacting with a beta(3)-containing integrin on astrocytes, could trigger signaling events similar to those generated by extracellular matrix proteins. DI-TNC(1) astrocytes were stimulated with Thy-1-Fc immobilized on beads, and increased RhoA activity was confirmed using an affinity precipitation assay. The effect of various inhibitors on the cellular response was also studied. The presence of Y-27632, an inhibitor of Rho kinase (p160ROCK), a key downstream effector of RhoA, significantly reduced focal adhesion and stress fiber formation induced by Thy-1. Similar effects were obtained when astrocytes were treated with C3 transferase, an inhibitor of RhoA. Alternatively, astrocytes were transfected with an expression vector encoding fusion proteins of enhanced green fluorescent protein with either the Rho-binding domain of Rhotekin, which blocks RhoA function, or the dominant-negative N19RhoA mutant. In both cases, Thy-1-induced focal adhesion formation was inhibited. Furthermore, we observed that RhoA activity after stimulation with soluble Thy-1-Fc molecule was augmented upon further cross-linking using protein A-Sepharose beads. The same was shown by cross-linking beta(3)-containing integrin with anti-beta(3) antibodies. Together, these results indicate that Thy-1-mediated astrocyte stimulation depended on beta(3) integrin clustering and the resulting increase in RhoA activity.
