Methods Control the methanol feeding in growth phase of Hansenula polymorpha by online monitoring. In induction phase, the expression levels of HBsAg when the methanol feeding were controlled by DO-Stat/pH-Stat method and by offline gas chromatography, as well as those when only methanol was fed and glycerol and methanol were fed alternatively, were compared.
