I’m happy to announce, and provide the link, for a just-published article, in which the protocol that we developed for sampling and isolating yeast cells from ancient clay vessels is detailed.
The full reference to this article is:
Aouizerat, T., Maeir, A. M., Paz, I., Gadot, Y., Szitenberg, A., Alkalay-Oren, S., Coppenhagen-Glazer, S., Klutstein, M., and Hazan, R. 2020. Isolation and Characterization of Live Yeast Cells from Ancient Clay Vessels. Bio-Protocol 10(1): https://doi.org/10.21769/BioProtoc.3473.
This protocol was successfully used by our team in a previously published paper (which has been mentioned previously):
Aouizerat, T., Gutmana, I., Paz, I., Maeir, A. M., Gadot, Y., Gleman, D., Szitenberg, A., Drori, E., Pinkus, A., Schoeman, M., Kaplan, R., Ben-Gedalya, T., Coppenhagen-Glazer, S., Reich, E., Saragovi, A., Lipschits, O., Klutstein, M., and Hazan, R. 2019. Isolation and Characterization of Live Yeast Cells from Ancient Vessels as a Tool in Bio-Archeology. MBio 10:e00388–19.
I hope this will be of utility to other archaeological teams!
