Diversidade de genes catabólicos em amostras de sedimentos do sistema estuarino de Santos e São Vicente, SP

Abstract: The catabolism of organic compounds in nature is one of the most important processes of nutrients recycle. Biodegradation process occurs by diversified enzymatic complex present in microorganisms, mainly in bacteria. Presence of catabolic genes encoding degradative enzymes can indicate a potential for bioremediation. The purpose of this work was to investigate the occurrence and diversity of catabolic genes in sediment samples of Santos and São Vicente Estuarine Systems, through culture-independent methods.

“…Crude oil/ formation water samples were not filtered or centrifuged before DNA extraction. The PCR amplifications of the three functional genes were performed independently using the respective set of primers (Table 1) [35]. Twenty five microliter reaction mixtures contained 5 µl of total DNA, 1 U Platinum Taq DNA polymerase (Invitrogen), 0.2 mM dNTP mix (GE Healthcare), 1.2 µM of each primer, 1X Taq buffer and 1.5 mM MgCl 2 .…”

“…Vale ressaltar que nos últimos anos, a detecção de genes que codificam dioxigenases, que era feita exclusivamente com primers específicos para cada gene, passou a ser realizada também com primers degenerados, devido à diversidade genética encontrada nas famílias das ARHDs. Esses primers foram desenhados com base na mesma região dos genes, que é a subunidade α do componente terminal da dioxigenase (BELICANTA, 2004;KUHN, 2007).…”

“…The mangrove metagenomic DNA was used as template for ARHD gene PCR-based amplification using the degenerate primers: ARHDf (TTY RYI TGY AII TAY CAY GGI TGG G) and ARHDr (AAI TKY TCI GCI GSI RMY TTC CA) (Bellicanta, 2005). These primers were designed to flank a highly conserved region of the alpha subunit from ARHD gene, with an expected amplicon size ranging between 300 and 329 bp.…”
