    FYI - please be SPECIFIC with today's picture. Most of you have gotten the general idea but need more specificity.

    Example. If the picture were of a white tiger it would not be sufficient to say a feline or a mammal...

    in other words.

    genus at least people :slight_smile:
    a guess at species is even better!
    (though you can't necessarily tell the species based solely on the picture)

    Was colloidal silver nanoparticles specific for quantum dots :wink:

    I really liked yesterdays, but I think the hint made it easy for people to google a few terms and then find the answer

    All we have to do is identify it? No additional significance or explanation necessary?

    not sure if i needed to be more specific, so i resubmitted with more details.

    If you can identify it I trust that you know the significance

    I also resubmitted my answer to be a bit more specific.

    Damn! I thought I'd make it back in time to submit. Oh well.

    isn't the species bruxellensis?

    bruxellensis and lambicus are the same species
    but yes... many people answered Bruxelensis ... a few answered just brettanomyces which I also took :slight_smile:

    really surprised that we lost some perfect scores on that one. almost seemed like a gimme to me.

    don't underestimate us former AP science students who have since abandoned the trade. i'm really surprised at how much of this i recognize or at least have a solid idea of based on the picture. kudos to my former teachers...perhaps i didn't choose my ideal profession as this is a lot of fun and i can't believe that i'm still in it!!!

    Ouch... I missed that one. That's what I get for never looking at what they look like under a microscope I suppose. I guess 6 out of 7 isn't too bad. For the record I asked a micro-biologist here at work after I came up with my answer. I will inform them they are dumb. Haha!

    I hated myself because I guessed Saccharomyces. Oh well.

    Same. I work with yeasts actually on my PhD thesis project and I guessed saccharomyces.

    There is really no way you can distinguish between several different types of yeasts under microscopy without some more information like scalebars to determine size, a larger field to see the change in morphology through the cell cycle, etc.

    If this were an exam question, I'd annoyed, but it's for free beer so :sunglasses:

    ahh, I did not know that. I was thinking they were different since white labs offers both a Brux and a lambicus. Also, I have seen then elsewhere mentioned separately. I just looked further into it and I guess only brux and anomalus are separate species and others are just synonyms.

    What a kick ass LIF, I love looking into other science fields. The last time I studied biology was in 9th grade. I was glad that I knew the photo right away, but had to go on a scavenger hunt to figure out the species...now I know why finding the difference between brux and lambicus was so hard.

    They are different strains of the same species!
    There are very few species of yeasts used in brewing but many many strains!

    I see, thanks. I am now off to read more about this. I wish I would have taken a biology course in college.
