Results
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. Tadaa.

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.
Protocol:PHO80 PHO85 FRT+ PHO85 Master mix (µL) 50 50 50 H2O DNAse Free (µL) 45 45 45 Resistance plasmid (µL) 1 1 1 PHO80 5'Primer (µL) 2 PHO80 3'Primer (µL) 2 PHO85 5'Primer (µL) 2 PHO85 3'Primer (µL) 2 PHO85 + FRT 5'Primer (µL) 2 PHO85 + FRT 3'Primer (µL) 2
