Another advantage of "P. pastoris" is its similarity to the well-studied yeast model — "Saccharomyces cerevisiae". As a model organism for biology, "S. cerevisiae" have been well studied for decades and used by researchers for various purposes throughout history. The two yeast genera; "Pichia" and "Saccharomyces", have similar growth conditions and tolerances; thus, the culture of "P. pastoris" can be adopted by labs without many modifications. Moreover, unlike "S. cerevisiae", "P. pastoris" has the ability to functionally process proteins with large molecular weight, which is useful in a translational host.
