Long-term release of such wastewater may result in the accumulation of heavy metals in soil exerting a selection pressure on soil micro-biota.
The presence of a particular compound in the feedstock content has the potential to exert a selection force in the fermentors that may favour some specific microorganisms (Tosetto 2008).
Overall farming approach (categorised here as organic, integrated and conventional) appeared to exert a selection pressure on the species composition of the seedbank, building up different communities under the three farming approaches over time.
Our data indicate a coevolutionary process, in which alfalfa exerts a selection pressure for resistance to MsSN1 on rhizobial bacteria.
The insecticides particles contained in the water could exert a selection pressure on the larvae of An. gambiae[ 27].
In this work, data also suggest a coevolutionary process, in which alfalfa exerts a selection pressure for resistance to MsSN1 on rhizobial bacteria.
Cytotoxic drugs had already been shown to exert a selection pressure on certain cancer cell lines, resulting in the enrichment of a of drug-resistant cancer cell fraction.
For example, Medel (2000) presented evidence that mistletoe infection exerts a selection pressure for long spines, which reduce perching of mistletoe dispersers, in Echinopsis chiloensis (Cactaceae).
The phylogenetic and functional analyses showed here, propose that MsSN1 is an ancestral plant gene involved in biotic stress resistance, suggesting a coevolutionary process, in which alfalfa exerts a selection pressure for resistance to MsSN1 on rhizobial bacteria.
Treatment options in severe infection are limited, and many infectious diseases practitioners and medical microbiologists are concerned about the resulting overuse of carbapenems exerting a selection pressure leading to the emergence of carbapenemase-producing microorganisms [ 3, 4].
