Cobalamin (vitamin B12) deficiency is widely spread in India, due to diet that is mostly vegetarian.
We aimed at introducing a high-level cobalamin producer to the rice batter.

Culture
The saccharomyces cerevisiae SK1 was thaw and sow 100µL of it on YPD medium overnight. (at 30°C)
This yeast will be transformed.
PCR
3 PCR were realized on OH plasmid to create a Kanamicine resistance marker, thanks to 3 pair of primers wich have tails we’ll be use to knock out genes PHO80, PHO85 and both in the yeast.
