Komagatella phaffi (Pichia pastoris)

    Technical Data

    Type of microorganism Yeast
    Microorganism name Komagatella phaffi (Pichia pastoris)
    Average yield in organism 1.5-2 g/L (average values from studies cited before)
    General temperature range 28-30 °C (average values from studies cited before)
    General pH range pH 5-6.5 (average values from studies cited before)
    Growth rate (µ)
    Ease of genetic modification Easy genetic manipulation, a lot of tools present (Lv & Cai, 2025)
    Feedstock case studies (suitable substrates) Corn waste, sugarcane leaves, soybean hydrolysate, rice bran, wheat bran, cottonseed hull, sugar beet molasses, bioethanol liquid waste, kitchen waste (Ergün et al., 2022)
    Downstream purification processing complexity (isloation, lysis, purification) * Possibility of adding a secretion signal to the protein, so easier purification & less downstream processing needed. (Spohner et al., 2015)
    Advantages Availability of strong, inducible promotors (like AOX1), easy genetic manipulation, low levels of host protein secretion,availibility of glycoeingineerd strains (Spohner et al., 2015)
    Challenges (Key limitations, risk factors) The strongest and most-used promotor is methanol-inducible, but methanol is toxic, flammable and explosive, making it hard to use in industrial context. (Pan et al., 2022)
