p>Alternatively,
Storms et al. define
adsorption efficiency as "The
adsorption efficiency is the fraction of
phage that
adsorbs irreversibly to the
host." Their definition and that presented above are equivalent in that the occurrence of phage-
bacterial collision is implicit to the Storms
et al. definition. The Storms
et al. definition is narrower, however, in that it also is implicitly suggestive that the failure to irreversibly adsorb is a relatively long-term property of the
virion particle rather than a

et al. effectively are rebranding the concept of
residual fraction as that phage
population defined by one minus adsorption efficiency.

et al. (1988) appear to use "adsorption efficiency" similarly. It is important to note, however, that when adsorption is measured using end-point determinations, rather than kinetically, then it can be difficult to distinguish between adsorption "inefficiency" as defined prior to this paragraph or instead in terms of a
residual fraction. That is, end-point adsorption determinations cannot distinguish between incomplete adsorption that has a occurred due to slow but consistent rates of adsorption versus the existence of two
phage populations, one that adsorbs relatively rapidly and one that does not.
Coetzee et al. (1986) by contrast use "adsorption efficiency" perhaps similarly to the concept of capacity, though in terms of phage adsorption to detached pili rather than to whole bacteria.
Note that the literature search employed to generate this entry was not exhaustive and indeed not only were a number of publications in which "adsorption efficiency" was used not cited, due to ambiguity in meaning, but in fact a substantial number of publications using this term were not examined by the author.
