Methanol addition after glucose depletion improves rPOXA 1B production under the pGap in P. pastoris X33: breaking the habit
Open accessAbstract
The purpose of this study was to demonstrate that methanol addition after glucose depletion has a positive effect on improving rPOXA 1B production under the control of pGap in P. pastoris.Four different culture media (A, B, C and D) were used to culture P. pastoris X33/pGapZα A-LaccPost-Stop(clone 1), containing a previously optimized POXA 1B synthetic gene coding for P. ostreatus laccase, which after glucose depletion was supplemented or not with methanol. Enzyme activity in culture media without methanol (A, B, C and D) was influenced by media components, presenting activity of 1254.30 ± 182.44, 1373.70 ± 182.44, 1343.50 ± 40.30 and 8771.61 ± 218.79 U L−1, respectively. In contrast, the same culture media (A, B, C and D) with methanol addition 24 h after glucose depletion attained activity of 4280.43 ± 148.82, 3339.02 ± 64.36, 3569.39 ± 68.38 and 14,868.06 ± 461.58 U L−1 at 192 h, respectively, representing an increase of approximately 3.9-, 2.4-, 3.3- and 1.6-fold compared with culture media without methanol. Methanol supplementation had a greater impact on volumetric enzyme activity in comparison with biomass production. We demonstrated what was theoretically and biochemically expected: recombinant protein production under pGap control by methanol supplementation after glucose depletion was successful, as a feasible laboratory production strategy of sequential carbon source addition, breaking the habit of utilizing pGap with glucose.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
