Saharan dust carries desert bacteria across the Atlantic to Amazon rainforest

Viewed under a microscope, the air above the Amazon rainforest teems with activity. It is full of pollen, fungal spores, tiny plant particles and bacteria. Normally, the composition of this bioaerosol community is quite stable. A team that included researchers from the University of Graz, the Max Planck Institute for Chemistry in Mainz and Brazilian partner institutions has now shown that microorganisms are transported across the Atlantic along with desert dust from the Sahara.
