An important point to emphasize here is the extreme
sensitivity of microorganisms generally to very small changes
in their chemical environment. Thus, by adjusting the concentration
of phosphate relative to that of other components in
the medium, the whole wall structure can be caused to
change radically. This change in wall composition can have
far-reaching consequences, as is shown not only by a
changed sensitivity to antibiotics and lytic agents (as mentioned
previously) but by a change in ability to bind certain
phages. 2° For example, it is known that bacteriophage ( ... )

the synthesis of a specific envelope protein that is
thought to function, in conjunction with the enterochelin,
as a high-affinity iron uptake system 37 and that serves as a
binding site for some phages (T1, T5 and ~b80).
могут действовать они не прямиком! Шасть в купе...
Finally, as
with a sulphate-limitation, an iron limitation has been
shown to affect the synthesis and function of some ironsulphur
proteins and to cause a loss of site 1 energy conservation
in Candida utilis cells.
