You know, Jay, I've been reading and hearing this for years now, about
the "grape-like" or "fruity" odor of P.aeruginosa. I know my sense of
smell is good, and every lab I've ever worked in thus far (since 1992)
has used this organism, among others, as a control bug (for media growth
promotions, USP preservative efficacy testing, preparatory testing for
USP microbial limits), so I'm very "intimate" with it. I've smelled pure
cultures of it and to me it has NEVER smelled like grapes or any other
kind of fruit. The pyocyanin I always see, yes, but I never smell the
odor I'm told it's supposed to have. Could this be the strain? The one I
always worked with (and still do) is ATCC 9027, and again, it doesn't
smell like fruit of any kind. No way! Do any of you others out here
notice what I do, or does this strain of P.aeruginosa smell like fruit to
*you*? (Maybe I've been inhaling too many kill loads lately?)
Infectionately,
Yersinia.
