Abstract: The objective of this work was to evaluate the catabolic gene diversity for the bacterial degradation of aromatic hydrocarbons in anthropogenic dark earth of Amazonia (ADE) and their biochar (BC). Functional diversity analyses in ADE soils can provide information on how adaptive microorganisms may influence the fertility of soils and what is their involvement in biogeochemical cycles. For this, clone libraries containing the gene encoding for the alpha subunit of aromatic ring-hydroxylating dioxygenase… Show more

“…The isolates' identification corroborates Navarrete et al [14] and Germano et al [15], who studied the bacterial community of ADE by strict molecular analysis and found the following bacterial phyla: Firmicutes, Proteobacteria, Verrucomicrobia, Acidobacteria, Gemmatimonadetes, Actinobacteria and Nitrospira.We had 78% of positive isolates for the degradation of phenanthrene and 86% of positive isolates for the degradation of diesel oil, but there were degradation capacity variations, which can be seen in Figures 1 and 2, for phenanthrene and diesel oil, respectively. In the Supplementary Material we provide the full visualization of all isolates for each substrate degradation.…”

“…Amongst the several microorganisms that are found on ADE, the most abundant bacteria are from the phyla, Firmicutes, Proteobacteria, Verrucomicrobia, Acidobacteria and Actinobacteria [14,15]. Some members have an infinite number of beneficial characteristics for ecology and the economy, being biodegraders, as well.…”

“…Amazon have also contributed to our understanding of the effects of land-use changes on the soil microbial communities (CENCIANI et al, 2009;O'NEILL et al, 2009;GROSSMAN et al, 2010;PAZINATO et al, 2010;NAVARRETE et al, 2011;GERMANO et al, 2012;TAKETANI et al, 2013).…”

“…Apesar do aumento da valorização da diversidade microbiana dos solos nas regiões tropicais, pouco ainda se sabe sobre a resposta de alguns táxons, e muito menos sobre aspectos funcionais, para as alterações nas propriedades químicas e fertilidade do solo em consequência do desmatamento e manejo agrícola dos solos de floresta. (CENCIANI et al, 2009;O'NEILL et al, 2009;GROSSMAN et al, 2010;PAZINATO et al, 2010;NAVARRETE et al, 2011;GERMANO et al, 2012;TAKETANI et al, 2013 Ferramentas de estatística e bioinformática foram utilizadas para integrar os dados para uma interpretação ecológica.…”
