Selective elimination of aphid endosymbionts: effects of antibiotic dose and host genotype, and fitness consequences.

abstract：:This paper demonstrates the first microbiological sampling of the Outokumpu deep borehole (2516 m deep) aiming at characterizing the bacterial community composition and diversity of sulphate-reducing bacteria (SRB) in Finnish crystalline bedrock aquifers. Sampling was performed using a 1500-m-long pressure-tight tube ...
