“Most engineers accept the ‘no free lunch’ principle, which states that any mechanism that increases robustness in one setting (i.e., to one type of perturbation, or with respect to one type of output) always compromises it in another” (Lander et 7al. 2009).


Extreme alkaliphiles, like extremophiles in general, possess numerous structural, metabolic, physiological, and bioenergetic adaptations that enable them to function well under their particular “extreme” condition or, in the case of poly-extremophiles, under several extreme conditions at once (see also  Chaps. 2.1 Introduction and History of Alkaliphiles,  2.4 Anaerobic Alkaliphiles and Alkaliphilic Poly-Extremophiles). If they are facultative extremophiles, many of the adaptations are present even under non-extreme growth conditions. That is, the adaptations to the extreme condition are “hard-wired” although their expression may increase further when the bacteria confront the extreme condition(s). The...
