Field Notes

Description:

This is the traditional yeast that makes beer, wine, other alcoholic drinks and bread. Is a unicelular organism that lives in colonies of multiple clones.
Images in green have particular proteins within the yeast tagged with a fluorescent green protein. The picture after shows colonies growing in a petri dish. The picture in blue shows calcofluor staining to see the bud scars that mother cells have when the daughter cells separate from them.

Habitat:

Laboratories and industries. In nature can be found in berries like grapes and flowers.

Notes:

Microscopy pictures made with a fluorescent microscope in laboratories where I worked over the years.

What an interesting field of work!

Hehee..the model organism of one scientist may be the annoying contaminant for another scientist :-) for people growing Drosophilas (fruit fly) yeast is food for their babies :-) anyway, I saw some people asking for microscopy pictures so I decided post a few from my daily life experiments :-)

Cool to see a unicellular organism on Noah Marta! Yeasts are fascinating. Still, I used to grow amphibian and mammalian cells and did not like to see yeasts in my Petri dishes!
