Abstract
β-1, 4-Endoglucanase (EG) from Bacillus subtilis LH was expressed in Escherichia coli Rosetta (DE3) and Pichia pastoris GS115, respectively. The CMCase activity of EG (EGE) from the cell lysate of DE3 reached 20,010U/ml, and that of EG (EGP) from the supernatant of GS115 was only 2008U/ml. EGE and EGP were bifunctional cellulases excluding β-1, 4-glucosidase (BGL). The CMCases of them, optimally active at 65°C and pH 6.8, exhibited more than 80% residual activity at pH 5-10 and 60% activity at 40-70°C and pH 5-9. EGE (EGP) mixed with BGL had more than 1.5-fold higher CMCase and filter paperase activities compared to EGE (EGP). N-glycosylation protected EGP from immobilized-papain attack and accounted for 30kDa and a higher thermostability, whereas EGE was decomposed into a 33kDa active truncated EG (EGT) and two 18kDa fragments. EGE and EGP performed much better than EGT in denim biostoning.

Engineering aggregation resistance in IgG by two independent mechanisms: lessons from comparison of Pichia pastoris and mammalian cell expression. J Mol Biol 2012; 417:309-35.

Abstract
Aggregation is an important concern for therapeutic antibodies, since it can lead to reduced bioactivity and increase the risk of immunogenicity. In our analysis of immunoglobulin G (IgG) molecules of identical amino acid sequence but produced either in mammalian cells (HEK293) or in the yeast Pichia pastoris (PP), dramatic differences in their aggregation susceptibilities were encountered. The antibodies produced in Pichia were much more resistant to aggregation under many conditions, a phenomenon found to be mainly caused by two factors. First, the mannose-rich glycan of the IgG from Pichia, while slightly thermally destabilizing the IgG, strongly inhibited its aggregation susceptibility, compared to the complex mammalian glycan. Second, on the Pichia-produced IgGs, amino acids belonging to the α-factor pre-pro sequence were left at the N-termini of both chains. These additional residues proved to considerably increase the temperature of the onset of aggregation and reduced the aggregate formation after extended incubation at elevated temperatures. The attachment of these residues to IgGs produced in cell culture confirmed their beneficial effect on the aggregation resistance. Secretion of IgGs with native N-termini in the yeast system became possible after systematic engineering of the precursor proteins and the processing site. Taken together, the present results will be useful for the successful production of full-length IgGs in Pichia, give indications on how to engineer aggregation-resistant IgGs and shed new light on potential biophysical effects of tag sequences in general.

Abstract
Having decided on yeast as a production host, the choice of species is often the first question any researcher new to the field will ask. With over 500 known species of yeast to date, this could pose a significant challenge. However, in reality, only very few species of yeast have been employed as host organisms for the production of recombinant proteins. The two most widely used, Saccharomyces cerevisiae and Pichia pastoris, are compared and contrasted here.

Abstract
Design of a unique, single-platform, integrated, multichannel sensor based on carbon nanotube (CNT)-protein adducts specific to each one of the major analytes of blood, glucose, cholesterol, triglyceride, and Hb1AC is presented. The concept underlying the sensor, amperometric detection, is applicable to various disease-monitoring strategies. There is an urgent need to enhance the sensitivity of glucometers to <5% level instead of greater than the present 15% standard in these detectors. CNTs enhance the signals derived from the interaction of the enzymes with the different analytes in blood. Fabricated sensors using the new methodology is a point-of-care device that is targeted for home, clinical, and emergency use and can be redesigned for continuous monitoring for critical care patients.

Abstract
Glycoengineering enabled the production of proteins with human N-linked glycans by Pichia pastoris. This study used a glycoengineered P. pastoris strain which is capable of producing humanized glycoprotein with terminal galactose for monoclonal antibody production. A design of experiments approach was used to optimize the process parameters. Followed by further optimization of the specific methanol feed rate, induction duration, and the initial induction biomass, the resulting process yielded up to 1.6 g/L of monoclonal antibody. This process was also scaled-up to 1,200-L scale, and the process profiles, productivity, and product quality were comparable with 30-L scale. The successful scale-up demonstrated that this glycoengineered P. pastoris fermentation process is a robust and commercially viable process.

Abstract
The Yarrowia lipolytica lipase LIP2 (YlLIP2) gene lip2 and Vitreoscilla hemoglobin gene vgb were co-expressed in Pichia pastoris, both under the control of AOX1 promoter, in order to alleviate respiration limitation under conditions of high cell-density fermentation and enhance YlLIP2 production. The results showed that recombinant P. pastoris strains harboring the lip2 and vgb genes (VHb(+)) displayed higher biomass and YlLIP2 activity than control strains (VHb(-)). Compared with VHb(-) cells, the expression levels of YlLIP2 in VHb-expressing cells when oxygen was not a limiting factor were improved 31.5% in shake-flask culture and 22% in a 10-L fermentor. Under non-limiting dissolved oxygen (DO) conditions, the maximum YlLIP2 activity of VHb(+) in a 10-L fermentor reached 33,000 U/mL. Oxygen limitation had a more negative effect on YlLIP2 productivity in VHb(-) cells than in VHb(+) cells. The highest YlLIP2 activity of VHb(+) cells was approximately 1.84-fold higher than that of VHb(-) cells at lower DO levels. Moreover, the recombinant strain VHb(+) exhibited a higher specific oxygen uptake rate and achieved higher cell viability under oxygen limiting and non-limiting conditions compared with VHb(-) cells. Therefore, the above results suggest that intracellular expression of VHb in recombinant P. pastoris has the potential to improve cell growth and industrial enzyme production.

Abstract
The aim of this article is to review how yeast has contributed to contemporary biotechnology and to seek underlying principles relevant to its future exploitation for human benefit. Recent advances in systems biology combined with new knowledge of genome diversity promise to make yeast the eukaryotic workhorse of choice for production of everything from probiotics and pharmaceuticals to fuels and chemicals. The ability to engineer new capabilities through introduction of controlled diversity based on a complete understanding of genome complexity and metabolic flux is key. Here, we briefly summarise the history that has led to these apparently simple organisms being employed in such a broad range of commercial applications. Subsequently, we discuss the likely consequences of current yeast research for the future of biotechnological innovation.

Abstract
African animal trypanosomosis (nagana) is arguably the most important parasitic disease affecting livestock in sub-Saharan Africa. Since none of the existing control measures are entirely satisfactory, vaccine development is being actively pursued. However, due to antigenic variation, the quest for a conventional vaccine has proven elusive. As a result, we have sought an alternative 'anti-disease vaccine approach', based on congopain, a cysteine protease of Trypanosoma congolense, which was shown to have pathogenic effects in vivo. Congopain was initially expressed as a recombinant protein in bacterial and baculovirus expression systems, but both the folding and yield obtained proved inadequate. Hence alternative expression systems were investigated, amongst which Pichia pastoris proved to be the most suitable. We report here the expression of full length, and C-terminal domain-truncated congopain in the methylotrophic yeast P. pastoris. Differences in yield were observed between full length and truncated proteins, the full length producing 2-4 mg of protein per litre of culture, while the truncated form produced 20-30 mg/l. The protease was produced as a proenzyme, but underwent spontaneous activation when acidified (pH <5). To investigate whether this activation was due to autolysis, we produced an inactive mutant (active site Cys→Ala) by site-directed mutagenesis. The mutant form was produced at a much higher rate, up to 100mg/l culture, as a proenzyme. It did not undergo spontaneous cleavage of the propeptide when subjected to acidic pH suggesting an autocatalytic process of activation for congopain. These recombinant proteins displayed a very unusual feature for cathepsin L-like proteinases, i.e. complete dimerisation at pH >6, and by reversibly monomerising at acidic pH <5. This attribute is of utmost importance in the context of an anti-disease vaccine, given that the epitopes recognised by the sera of trypanosome-infected trypanotolerant cattle appear dimer-specific.

Abstract
The production of heterologous proteins by secretion from cellular hosts is an important determinant for the cost of biotherapeutics. A single-cell analytical method called microengraving was used to examine the heterogeneity in secretion by the methylotrophic yeast Pichia pastoris. We show that constitutive secretion of a human Fc fragment by P. pastoris is not cell-cycle dependent, but rather fluctuates between states of high and low productivity in a stochastic manner.

Abstract
Background The prevalence of diabetes is predicted to rise significantly in the coming decades. A recent analysis projects that by the year 2030 there will be ~366 million diabetics around the world, leading to an increased demand for inexpensive insulin to make this life-saving drug also affordable for resource poor countries. Results A synthetic insulin precursor (IP)-encoding gene, codon-optimized for expression in P. pastoris, was cloned in frame with the Saccharomyces cerevisiae α-factor secretory signal and integrated into the genome of P. pastoris strain X-33. The strain was grown to high-cell density in a batch procedure using a defined medium with low salt and high glycerol concentrations. Following batch growth, production of IP was carried out at methanol concentrations of 2 g L-1, which were kept constant throughout the remaining production phase. This robust feeding strategy led to the secretion of ~3 gram IP per liter of culture broth (corresponding to almost 4 gram IP per liter of cell-free culture supernatant). Using immobilized metal ion affinity chromatography (IMAC) as a novel approach for IP purification, 95% of the secreted product was recovered with a purity of 96% from the clarified culture supernatant. Finally, the purified IP was trypsin digested, transpeptidated, deprotected and further purified leading to ~1.5 g of 99% pure recombinant human insulin per liter of culture broth. Conclusions A simple two-phase cultivation process composed of a glycerol batch and a constant methanol fed-batch phase recently developed for the intracellular production of the Hepatitis B surface antigen was adapted to secretory IP production. Compared to the highest previously reported value, this approach resulted in an ~2 fold enhancement of IP production using Pichia based expression systems, thus significantly increasing the efficiency of insulin manufacture.

Abstract
The beneficial fungus Trichoderma virens secretes a small cysteine-rich protein (Sm1) that induces defense responses in dicot and monocot plants and is a member of the cerato-platanin family. Purification of Sm1 from T. virens results in low protein yield limiting the application of this protein for crop disease protection to small-scale assays. To increase the yield of Sm1, we cloned the sm1 gene in the pPIC9K vector for transformation into the AOX1 locus of Pichia pastoris strain GS115. Transformants of P. pastoris were selected based on the presence of the vector insert as indicated by PCR analysis and the ability to secrete high levels of the rSm1 protein. The optimal incubation period and methanol concentrations for induction were determined for production of rSm1 in shake flasks. One Pichia transformant was estimated to express approximately 55 mg/l of rSm1 after 4 days culture in a 1% final concentration of methanol. The secreted rSm1 was purified by ammonium sulfate precipitation, ion exchange chromatography and gel column chromatography. SDS-PAGE and Western blot analysis revealed that the purified rSm1 expressed in Pichia was recognized by anti-Sm1 polyclonal antibody. The protein sequence was verified by ESI/MS/MS analysis of a tryptic digest of the rSm1. Greater than 90% peptide coverage was obtained and determined to be identical to the predicted sequence. The MALDI/TOF/MS analysis revealed the molecular mass of rSm1 to be 13.1 kDa, which is higher than native Sm1 (12.6 kDa). Edman sequencing of the purified protein revealed an N-terminal extension of six amino acids (EAEAYV). The extension is the result of insufficient activity of the Ste13 protease preventing efficient cleavage of the spacer (EAEA) downstream of the Kex2 cleavage site. Maize (cv. Silver Queen) treated with rSm1 or native Sm1 demonstrated the induction of two defense genes. Enhanced production of this elicitor has implications for the treatment of specialty crops to promote disease resistance.

Abstract
High-level extracellular production of Fusarium solani cutinase was achieved using a Pichia pastoris expression system. The cutinase-encoding gene was cloned into pPICZalphaA with the Saccharomyces cerevisiae alpha-factor signal sequence and methanol-inducible alcohol oxidase promoter by two different ways. The additional sequences of the c-myc epitope and (His)6-tag of the vector were fused to the C-terminus of cutinase, while the other expression vector was constructed without any additional sequence. P. pastoris expressing the non-tagged cutinase exhibited about two- and threefold higher values of protein amount and cutinase activity in the culture supernatant, respectively. After simple purification by diafiltration process, both cutinases were much the same in the specific activity and the biochemical properties such as the substrate specificity and the effects of temperature and pH. In conclusion, the high-level secretion of F. solani cutinase in P. pastoris was demonstrated for the first time and would be a promising alternative to many expression systems previously used for the large-scale production of F. solani cutinase in Saccharomyces cerevisiae as well as Escherichia coli.

Secreted production of an elastin-like polypeptide by Pichia pastoris. Appl Microbiol Biotechnol 2009; 85:293-301.

Abstract
Elastin-like polypeptides (ELPs) are biocompatible designer polypeptides with inverse temperature transition behavior in solution. They have a wide variety of possible applications and a potential medical importance. Currently, production of ELPs is done at lab scale in Escherichia coli shake flask cultures. With a view to future large scale production, we demonstrate secreted production of ELPs in methanol-induced fed-batch cultures of Pichia pastoris and purification directly from the culture medium. The production of ELPs by P. pastoris proved to be pH dependent within the experimental pH range of pH 3 to 7, as an increasing yield was found in cultures grown at higher pH. Because ELP produced at pH 7 was partly degraded, a pH optimum for production of ELP was found at pH 6 with a yield of 255 mg of purified intact ELP per liter of cell-free medium.

Abstract
Background Hepatitis B is a serious global public health concern. Though a safe and efficacious recombinant vaccine is available, its use in several resource-poor countries is limited by cost. We have investigated the production of Hepatitis B virus surface antigen (HBsAg) using the yeast Pichia pastoris GS115 by inserting the HBsAg gene into the alcohol oxidase 1 locus. Results Large-scale production was optimized by developing a simple fed-batch process leading to enhanced product titers. Cells were first grown rapidly to high-cell density in a batch process using a simple defined medium with low salt and high glycerol concentrations. Induction of recombinant product synthesis was carried out using rather drastic conditions, namely through the addition of methanol to a final concentration of 6 g L-1. This methanol concentration was kept constant for the remainder of the cultivation through continuous methanol feeding based on the on-line signal of a flame ionization detector employed as methanol analyzer in the off-gas stream. Using this robust feeding protocol, maximum concentrations of ~7 grams HBsAg per liter culture broth were obtained. The amount of soluble HBsAg, competent for assembly into characteristic virus-like particles (VLPs), an attribute critical to its immunogenicity and efficacy as a hepatitis B vaccine, reached 2.3 grams per liter of culture broth. Conclusion In comparison to the highest yields reported so far, our simple cultivation process resulted in an ~7 fold enhancement in total HBsAg production with more than 30% of soluble protein competent for assembly into VLPs. This work opens up the possibility of significantly reducing the cost of vaccine production with implications for expanding hepatitis B vaccination in resource-poor countries.

Abstract
Pichia pastoris is an efficient host for the expression and secretion of heterologous proteins and the most important feature of P. pastoris is the existence of a strong and tightly regulated promoter from the alcohol oxidase I (AOX1) gene. The AOX1 promoter (pAOX1) has been used to express foreign genes and to produce a variety of recombinant proteins in P. pastoris. However, some efforts have been made to develop new alternative promoters to pAOX1 to avoid the use of methanol. The glyceraldehyde-3-phosphate dehydrogenase promoter (pGAP) has been used for constitutive expression of many heterologous proteins. The pGAP-based expression system is more suitable for large-scale production because the hazard and cost associated with the storage and delivery of large volume of methanol are eliminated. Some important developments and features of this expression system will be summarized in this review.
