This hypothetical "multi-requirement" of MgtC is in accordance to several reports suggesting a connection of this virulence factor with the structural stability of Mg2+ channels in the bacterial cell membrane [7], linked to survival in Mn+2 depleted environments, or modifying the membrane potential of the host cell and affecting the host-pathogen interaction [33], [34].
Acquiring the ability to ferment novel substrates and/or to grow syntrophically could have facilitated expansion into Fe(III) oxide depleted environments.
Dr. Warhurst said that attempts to deregulate the fracking industry, coupled with the possibility of more austerity against an already depleted Environment Agency, will leave SSSIs under the threat of fracking even more at risk.

It has been shown experimentally that increasing the levels of BAFF in a B cell depleted environment can promote the survival of autoreactive B cells that would normally be silenced [22].
It has been postulated that a function of these adhesins may be similar to the FLO genes of S. cerevisiae [60], which also encode surface glycoproteins that promote cell to cell interactions, especially in a nutritionally depleted environment.
This energy metabolism versatility would be advantageous in this highly depleted environment, where secondary production might be boosted by chemolithotrophy much in the way that phototrophy helps heterotrophy at the surface [43].
This approach has been proven to be effective on prokaryotic communities [11], [24], [25], but to date has only been applied on protist communities in an oxygen depleted environment [26].
Furthermore, they are able to create an iron depleted environment in the phagosome by the activity of the natural resistance associated membrane protein (NRAMP) transporter [ 28, 29].
In conclusion, the experimental design to generate transcription profiles for gills at five time points over a 14-day period allowed us to study the changes in expression of individual genes during the period of acclimation to a zinc depleted environment.
The first was improved immune response to tumor cells based on a significant reduction of the IL-12 mediated antitumor effect in a T-cell or NK-cell depleted environment [ 8] and the development of antitumor resistance after the combined treatment modality [ 9].
