The objective of this study is to assess the uncultured bacterial diversity in the snowpack of the Mont Blanc (MtBl) glacier containing Saharan dust deposited during four dust events over the period 2006 - 2009, by means of molecular phylogenetics. Bacterial diversity was evaluated using rybotyping and subsequent sequencing of partial (V3-V5) and full-length 16S rRNA genes. For comparison purpose we also studied following samples: MtBl snow containing no Saharan dust (by both rDNA and rRNA approaches); Saharan sand collected in Tunisia; Saharan dust collected in Grenoble (200 m a.s.l.) and recovered later on MtBl (4250 m a.s.l.). Species content and dominant phylotypes and their assigning to major divisions varied significantly in alpine sn...
