Abstract
The production of recombinant biopharmaceutical proteins is a multi-billion dollar market. Protein recovery represents a major part of the production costs. Pichia pastoris is one of the microbial systems most used for the production of heterologous proteins. The use of a cold-induced promoter to express lytic enzymes in the yeast after the growth stage could reduce protein recovery costs. This study shows that a cold-shock can be applied to induce lysis of the yeast cells. A strain of P. pastoris was constructed in which the endogenous eng gene encoding a putative endo-β-1,3-glucanase was overexpressed using the cold-shock induced promoter of the cctα gene from Saccharomyces cerevisiae. In the transgenic P. pastoris, the expression of eng increased 3.6-fold after chilling the cells from 30 to 4 °C (cold-shock stage) followed by incubation for 6 h (eng expression stage). The culture was heated to 30 °C for 6 h (ENG synthesis stage) and kept at 37 °C for 24 h (lysis stage). After this procedure the cell morphology changed, spheroplasts were obtained and cellular lysis was observed. Thus, a clone of P. pastoris was obtained, which undergoes autolysis after a cold-shock.

Abstract
The methylotrophic yeast Komagataella (Pichia) pastoris has become one of the most utilized cell factories for the production of recombinant proteins over the last three decades. This success story is linked to its specific physiological traits, i.e., the ability to grow at high cell density in inexpensive culture medium and to secrete proteins at high yield. Exploiting methanol metabolism is at the core of most P. pastoris-based processes but comes with its own challenges. Co-feeding cultures with glycerol/sorbitol and methanol is a promising approach, which can benefit from improved understanding and prediction of metabolic response. The development of profitable processes relies on the construction and selection of efficient producing strains from less efficient ones but also depends on the ability to master the bioreactor process itself. More specifically, how a bioreactor processes could be monitored and controlled to obtain high yield of production. In this review, new perspectives are detailed regarding a multi-faceted approach to recombinant protein production processes by P. pastoris; including gaining improved understanding of the metabolic pathways involved, accounting for variations in transcriptional and translational efficiency at the single cell level and efficient monitoring and control of methanol levels at the bioreactor level.

Abstract
Pichia pastoris has been recognized as one of the most industrially important hosts for heterologous protein production. Despite its high protein productivity, the optimization of P. pastoris cultivation is still imperative due to strain- and product-specific challenges such as promoter strength, methanol utilization type and oxygen demand. To address the issues, strategies involving genetic and process engineering have been employed. Optimization of codon usage and gene dosage, as well as engineering of promoters, protein secretion pathways and methanol metabolic pathways have proved beneficial to innate protein expression levels. Large-scale production of proteins via high cell density fermentation additionally relies on the optimization of process parameters including methanol feed rate, induction temperature and specific growth rate. Recent progress related to the enhanced production of proteins in P. pastoris via various genetic engineering and cultivation strategies are reviewed. Insight into the regulation of the P. pastoris alcohol oxidase 1 (AOX1) promoter and the development of methanol-free systems are highlighted. Novel cultivation strategies such as mixed substrate feeding are discussed. Recent advances regarding substrate and product monitoring techniques are also summarized. Application of P. pastoris to the production of biodiesel and other value-added products via metabolic engineering are also reviewed. P. pastoris is becoming an indispensable platform through the use of these combined engineering strategies.

Abstract
Pichia pastoris is widely used as a platform for heterologous protein expression because of its high volumetric productivity. Multicopy integration of the target gene is commonly used to improve the production of the target protein. Cre/lox recombination system is a powerful tool for the marker rescue during multiple integrations with one selection marker. Here we reported a novel expression vector based on the Cre/lox recombination system for multiple integrations of target gene to construct multicopy expression strain of P. pastoris. PAOX1 promoter was fused to cre to construct a methanol inducible Cre recombinase. The leakage expression of Cre recombinase in Escherichia coli was blocked by introducing the operator gene lacO. The expression vector designed pMCO-AOXα was stable in E. coli and could effectively rescue the Zeocin resistance gene for next round of integration in P. pastoris. Phytase AppA from E. coli was chosen as a reporter gene. Transformants with 2-16 copies of appA were constructed by using a single antibiotic. Expression of appA was gene dosage dependent when <12 copies were integrated. The protein yield increased 4.45-folds when 12 copies of appA were integrated comparing with the single copy integration. Our results showed that pMCO-AOXα was highly effective for rational construction of multicopy transformat in P. pastoris.

Abstract
The constitutive glyceraldehyde-3-phosphate dehydrogenase promoter (PGAP ), which is one of the benchmark promoters of Pichia pastoris, was analyzed in terms of putative transcription factor binding sites. We constructed a synthetic library with distinct regulatory properties through deletion and duplication of these putative transcription factor binding sites and selected transcription factor (TF) genes were overexpressed or deleted to understand their roles on heterologous protein production. Using enhanced green fluorescent protein, an expression strength in a range between 0.35- and 3.10-fold of the wild-type PGAP was obtained. Another model protein, recombinant human growth hormone was produced under control of selected promoter variants and 1.6- to 2.4-fold higher product titers were reached compared to wild-type PGAP . In addition, a GAL4-like TF was found to be a crucial factor for the regulation of PGAP , and its overexpression enhanced the heterologous protein production considerably (up to 2.2-fold compared to the parental strain). The synthetic PGAP library generated enabled us to investigate the different putative transcription factors which are responsible for the regulation of PGAP under different growth conditions, ergo recombinant protein production under PGAP .

Abstract
BACKGROUND Pichia pastoris shows physiological advantages in producing recombinant proteins, compared to other commonly used cell factories. This yeast is mostly grown in dynamic cultivation systems, where the cell's environment is continuously changing and many variables influence process productivity. In this context, a model capable of explaining and predicting cell behavior for the rational design of bioprocesses is highly desirable. Currently, there are five genome-scale metabolic reconstructions of P. pastoris which have been used to predict extracellular cell behavior in stationary conditions. RESULTS In this work, we assembled a dynamic genome-scale metabolic model for glucose-limited, aerobic cultivations of Pichia pastoris. Starting from an initial model structure for batch and fed-batch cultures, we performed pre/post regression diagnostics to ensure that model parameters were identifiable, significant and sensitive. Once identified, the non-relevant ones were iteratively fixed until a priori robust modeling structures were found for each type of cultivation. Next, the robustness of these reduced structures was confirmed by calibrating the model with new datasets, where no sensitivity, identifiability or significance problems appeared in their parameters. Afterwards, the model was validated for the prediction of batch and fed-batch dynamics in the studied conditions. Lastly, the model was employed as a case study to analyze the metabolic flux distribution of a fed-batch culture and to unravel genetic and process engineering strategies to improve the production of recombinant Human Serum Albumin (HSA). Simulation of single knock-outs indicated that deviation of carbon towards cysteine and tryptophan formation improves HSA production. The deletion of methylene tetrahydrofolate dehydrogenase could increase the HSA volumetric productivity by 630%. Moreover, given specific bioprocess limitations and strain characteristics, the model suggests that implementation of a decreasing specific growth rate during the feed phase of a fed-batch culture results in a 25% increase of the volumetric productivity of the protein. CONCLUSION In this work, we formulated a dynamic genome scale metabolic model of Pichia pastoris that yields realistic metabolic flux distributions throughout dynamic cultivations. The model can be calibrated with experimental data to rationally propose genetic and process engineering strategies to improve the performance of a P. pastoris strain of interest.

Abstract
In this review article, extremophilic lignocellulosic enzymes with special interest on xylanases, β-mannanases, laccases and finally cellulases, namely, endoglucanases, exoglucanases and β-glucosidases produced by Pichia pastoris are reviewed for the first time. Recombinant lignocellulosic extremozymes are discussed from the perspectives of their potential application areas; characteristics of recombinant and native enzymes; the effects of P. pastoris expression system on recombinant extremozymes; and their expression levels and applied strategies to increase the enzyme expression yield. Further, effects of enzyme domains on activity and stability, protein engineering via molecular dynamics simulation and computational prediction, and site-directed mutagenesis and amino acid modifications done are also focused. Superior enzyme characteristics and improved stability due to the proper post-translational modifications and better protein folding performed by P. pastoris make this host favourable for extremozyme production. Especially, glycosylation contributes to the structure, function and stability of enzymes, as generally glycosylated enzymes produced by P. pastoris exhibit better thermostability than non-glycosylated enzymes. However, there has been limited study on enzyme engineering to improve catalytic efficiency and stability of lignocellulosic enzymes. Thus, in the future, studies should focus on protein engineering to improve stability and catalytic efficiency via computational modelling, mutations, domain replacements and fusion enzyme technology. Also metagenomic data need to be used more extensively to produce novel enzymes with extreme characteristics and stability.

Abstract
B-cell maturation antigen (BCMA) fused at the C-terminus to the Fc portion of human IgG1 (BCMA-Fc) blocks B-cell activating factor (BAFF) and proliferation-inducing ligand (APRIL)-mediated B-cell activation, leading to immune disorders. The fusion protein has been cloned and produced by several engineering cell lines. To reduce cost and enhance production, we attempted to express recombinant human BCMA-Fc (rhBCMA-Fc) in Pichia pastoris under the control of the AOX1 methanol-inducible promoter. To produce the target protein with uniform molecular weight and reduced immunogenicity, we mutated two predicted N-linked glycosylation sites. The secretory yield was improved by codon optimization of the target gene sequence. After fed-batch fermentation under optimized conditions, the highest yield (207 mg/L) of rhBCMA-Fc was obtained with high productivity (3.45 mg/L/h). The purified functional rhBCMA-Fc possessed high-binding affinity to APRIL and dose-dependent inhibition of APRIL-induced proliferative activity in vitro through three-step purification. Thus, this yeast-derived expression method could be a low-cost and effective alternative to the production of rhBCMA-Fc in mammalian cell lines.

Abstract
OBJECTIVES To develop a new vector for constitutive expression in Pichia pastoris based on the endogenous glycolytic PGK1 promoter. RESULTS P. pastoris plasmids bearing at least 415 bp of PGK1 promoter sequences can be used to drive plasmid integration by addition at this locus without affecting cell growth. Based on this result, a new P. pastoris integrative vector, pPICK2, was constructed bearing some features that facilitate protein production in this yeast: a ~620 bp PGK1 promoter fragment with three options of restriction sites for plasmid linearization prior to yeast transformation: a codon-optimized α-factor secretion signal, a new polylinker, and the kan marker for vector propagation in bacteria and selection of yeast transformants. CONCLUSIONS A new constitutive vector for P. pastoris represents an alternative platform for recombinant protein production and metabolic engineering purposes.

Abstract
Abstract
Seventeen carbon sources were screened to identify those with the potential to support pGAP-regulated recombinant enzyme production by Pichia pastoris, using phytase as a model product. Of these, four, namely glucose, glycerol, fructose and ethanol, supported cell growth and enzyme production, and the performance of the latter two was analyzed. Ranges of acceptable residual carbon source concentrations, i.e. those at which no substrate-related growth inhibition occurred, were determined and used to design fed-batch bioreactor-based processes. In fed-batch cultures, fructose supported higher biomass concentrations and equivalent extracellular enzyme activities than glucose. The same metrics for the cultures grown on ethanol were comparable to those of the cultures grown on glucose, but with a greater required fermentation time.

Abstract
UNLABELLED In this study, we co-expressed the human prolyl 4-hydroxylases (P4H) with human collagen α1 (III) (COL3A1) in an inducible system: Pichia pastoris (pPICZB), and one constitutive system: P. pastoris (pGAPZαB). The P4H catalyses the post-translational hydroxylation of proline residues in collagen strands. Conventional protein expression system such as bacteria and yeasts, which lack endogenous P4H, are not efficient for the production of recombinant collagen. In this study, the P4H gene was constructed in pGAPZαB plasmid and pPICZB plasmid respectively. These two plasmids were transformed in P. pastoris #1 that carrying COL3A1. Colony PCR analysis and sequencing after electroporation P. pastoris GS115 showed that the target gene had inserted successfully. The results of reverse transcript-qPCR, SDS-PAGE, Western blotting and LC-MS/MS analysis of the rhCOL3A1 demonstrated that the P4H was expressed successfully. Besides, it is noted that low copy number, constitutive system was suitable for hydroxylated rhCOL3A1. SIGNIFICANCE AND IMPACT OF THE STUDY Successful co-expression of recombinant human collagen α1 (III) (rhCOL3A1) and human prolyl 4-hydroxylases (P4H) in Picha pastoris GS115, simultaneously results in the acquisition of rhCOL3A1 with hydroxylation of proline (Hyp). Further, this experiment also discusses that the high or low copy numbers and different promoters affect the Hyp degree of rhCOL3A1. Selecting more appropriate strains can express high degree Hyp of rhCOL3A1. This work will be helpful to the collagen structure study.
