| phylogenetic analysis of the archaeal community in an alkaline-saline soil of the former lake texcoco (mexico). | the soil of the former lake texcoco is an extreme environment localized in the valley of mexico city, mexico. it is highly saline and alkaline, where na+, cl(-), hco3(-) and co3(2-) are the predominant ions, with a ph ranging from 9.8 to 11.7 and electrolytic conductivities in saturation extracts from 22 to 150 ds m(-1). metagenomic dna from the archaeal community was extracted directly from soil and used as template to amplify 16s ribosomal gene by pcr. pcr products were used to construct gene ... | 2008 | 18097633 |
