Abstract
Bio-refining lignocellulose could provide a sustainable supply of fuels and fine chemicals; however, the challenges associated with the co-utilization of xylose and glucose typically compromise the efficiency of lignocellulose conversion. Here we engineered the industrial yeast Ogataea polymorpha (Hansenula polymorpha) for lignocellulose biorefinery by facilitating the co-utilization of glucose and xylose to optimize the production of free fatty acids (FFAs) and 3-hydroxypropionic acid (3-HP) from lignocellulose. We rewired the central metabolism for the enhanced supply of acetyl-coenzyme A and nicotinamide adenine dinucleotide phosphate hydrogen, obtaining 30.0 g l-1 of FFAs from glucose, with productivity of up to 0.27 g l-1 h-1. Strengthening xylose uptake and catabolism promoted the synchronous utilization of glucose and xylose, which enabled the production of 38.2 g l-1 and 7.0 g l-1 FFAs from the glucose-xylose mixture and lignocellulosic hydrolysates, respectively. Finally, this efficient cell factory was metabolically transformed for 3-HP production with the highest titer of 79.6 g l-1 in fed-batch fermentation in mixed glucose and xylose.

Enhancing Antimicrobial Peptide Productivity in Pichia pastoris (Muts Strain) by Improving the Fermentation Process Based on Increasing the Volumetric Methanol Consumption Rate. FERMENTATION-BASEL 2023.

Abstract
The instability of the protein expression in Pichia pastoris strains has been an issue for various peptide productions. Some modifications to the traditional fermentation process could potentially solve the problem. Here, we consider a four-stage fermentation process to express the CAP2 (cell-penetrating antimicrobial peptide 2) candidate in P. pastoris KM71H, a slow methanol utilization strain. During the fermentation process, CAP2 productivity is limited (6.15 ± 0.21 mg/L·h) by the low overall methanol consumption (approximately 645 g), which is mainly the result of the slow methanol utilization of the P. pastoris KM71H. To overcome this limitation, we increased the cell concentration two-fold prior to the induction stage. A fed-batch process with exponential and dissolved oxygen tension (DOT) stat feeding strategies was deployed to control the glycerol feed, resulting in an increase in cell concentration and enhancement of the volumetric methanol consumption rate. The improved fermentation process increased the overall methanol consumption (approximately 1070 g) and the CAP2 productivity (13.59 ± 0.24 mg/L·h) by 1.66 and 2.21 times, respectively. In addition, the CAP3 (cell-penetrating antimicrobial peptide 3) candidate could also be produced using this improved fermentation process at a high yield of 3.96 ± 0.02 g/L without any further optimization. Note that there was no oxygen limitation during the improved fermentation process operating at high cell density. This could be due to the controlled substrate addition via the DOT stat system.

Abstract
Yeast is widely used in the fermentation industry, and the major challenges in fermentation production system are high capital cost and low reaction rate. High cell-density culture is an effective method to increase the volumetric productivity of the fermentation process, thus making the fermentation process faster and more robust. During fermentation, yeast is subjected to various environmental stresses, including osmotic, ethanol, oxidation, and heat stress. To cope with these stresses, yeast cells need appropriate adaptive responses to acquire stress tolerances to prevent stress-induced cell damage. Since a single stressor can trigger multiple effects, both specific and nonspecific effects, general and specific stress responses are required to achieve comprehensive protection of cells. Since all these stresses disrupt protein structure, the upregulation of heat shock proteins and trehalose genes is induced when yeast cells are exposed to stress. A better understanding of the research status of yeast HCDC and its underlying response mechanism to various stresses during fermentation is essential for designing effective culture control strategies and improving the fermentation efficiency and stress resistance of yeast.

Abstract
Multiple yeast strains have been developed into versatile heterologous protein expression platforms. Earlier works showed that Ogataea thermomethanolica TBRC 656 (OT), a thermotolerant methylotrophic yeast, can efficiently produce several industrial enzymes. In this work, we demonstrated the potential of this platform for biopharmaceutical manufacturing. Using a swine vaccine candidate as a model, we showed that OT can be optimized to express and secrete the antigen based on porcine circovirus type 2d capsid protein at a respectable yield. Crucial steps for yield improvement include codon optimization and reduction of OT protease activities. The antigen produced in this system could be purified efficiently and induce robust antibody response in test animals. Improvements in this platform, especially more efficient secretion and reduced extracellular proteases, would extend its potential as a competitive platform for biopharmaceutical industries.

Abstract
Methylotrophic yeasts have been widely recognized as a promising host for production of recombinant proteins and value-added chemicals. Promoters for controlled gene expression are critical for construction of efficient methylotrophic yeasts cell factories. Here, we summarized recent advances in characterizing and engineering promoters in methylotrophic yeasts, such as Komagataella phaffii and Ogataea polymorpha. Constitutive and inducible promoters controlled by methanol or other inducers/repressors were introduced to demonstrate their applications in production of proteins and chemicals. Furthermore, efforts of promoter engineering, including site-directed mutagenesis, hybrid promoter, and transcription factor regulation to expand the promoter toolbox were also summarized. This mini-review also provides useful information on promoters for the application of metabolic engineering in methylotrophic yeasts. KEY POINTS: • The characteristics of six methylotrophic yeasts and their promoters are described. • The applications of Komagataella phaffii and Ogataea polymorpha in metabolic engineeringare expounded. • Three promoter engineering strategies are introduced in order to expand the promoter toolbox.

Abstract
CRISPR multiplex gRNA systems have been employed in genome engineering in various industrially relevant yeast species. The thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC 656 is an alternative host for heterologous protein production. However, the limited secretory capability of this yeast is a bottleneck for protein production. Here, we refined CRISPR-based genome engineering tools for simultaneous mutagenesis and activation of multiple protein secretory pathway genes to improve heterologous protein secretion. We demonstrated that multiplexed CRISPR-Cas9 mutation of up to four genes (SOD1, VPS1, YPT7 and YPT35) in one single cell is practicable. We also developed a multiplexed CRISPR-dCas9 system which allows simultaneous activation of multiple genes in this yeast. 27 multiplexed gRNA combinations were tested for activation of three genes (SOD1, VPS1 and YPT7), three of which were demonstrated to increase the secretion of fungal xylanase and phytase up to 29% and 41%, respectively. Altogether, our study provided a toolkit for mutagenesis and activation of multiple genes in O. thermomethanolica, which could be useful for future strain engineering to improve heterologous protein production in this yeast.

Abstract
The thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC 656 is a potential host strain for industrial protein production. Heterologous proteins are often retained intracellularly in yeast resulting in endoplasmic reticulum (ER) stress and poor secretion, and despite efforts to engineer protein secretory pathways, heterologous protein production is often lower than expected. We hypothesized that activation of genes involved in the secretory pathway could mitigate ER stress. In this study, we created mutants defective in protein secretory-related functions using clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein 9 (Cas9) tools. Secretion of the model protein xylanase was significantly decreased in loss of function mutants for oxidative stress (sod1Δ) and vacuolar and protein sorting (vps1Δ and ypt7Δ) genes. However, xylanase secretion was unaffected in an autophagy related atg12Δ mutant. Then, we developed a system for sequence-specific activation of target gene expression (CRISPRa) in O. thermomethanolica and used it to activate SOD1, VPS1 and YPT7 genes. Production of both non-glycosylated xylanase and glycosylated phytase was enhanced in the gene activated mutants, demonstrating that CRISPR-Cas9 systems can be used as tools for understanding O. thermomethanolica genes involved in protein secretion, which could be applied for increasing heterologous protein secretion in this yeast.

Abstract
The thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC656 is a potential host for heterologous protein production. However, overproduction of heterologous protein can induce cellular stress and limit the level of its secretion. To improve the secretion of heterologous protein, we identified the candidate proteins with altered production during production of heterologous protein in O. thermomethanolica by using a label-free comparative proteomic approach. Four hundred sixty-four proteins with various biological functions showed differential abundance between O. thermomethanolica expressing fungal xylanase (OT + Xyl) and a control strain. The induction of proteins in transport and proteasomal proteolysis was prominently observed. Eight candidate proteins involved in cell wall biosynthesis (Chs3, Gas4), chaperone (Sgt2, Pex19), glycan metabolism (Csf1), protein transport (Ypt35), and vacuole and protein sorting (Cof1, Npr2) were mutated by a CRISPR/Cas9 approach. An Sgt2 mutant showed higher phytase and xylanase activity compared with the control strain (13%-20%), whereas mutants of other genes including Cof1, Pex19, Gas4, and Ypt35 showed lower xylanase activity compared with the control strain (15%-25%). In addition, an Npr2 mutant showed defective growth, while overproduction of Npr2 enhanced xylanase activity. These results reveal genes that can be mutated to modulate heterologous protein production and growth of O. thermomethanolica TBRC656.

Abstract
Methylotrophic yeasts have been used as the platform for expression of heterologous proteins since the
1980’s. They are highly productive and allow producing eukaryotic proteins with an acceptable glycosylation level.
The first Pichia pastoris-based system for expression of recombinant protein was developed on the basis of the treeexudate-
derived strain obtained in the US southwest. Being distributed free of charge for scientific purposes, this system
has become popular around the world. As methylotrophic yeasts were classified in accordance with biomolecular
markers, strains used for production of recombinant protein were reclassified as Komagataella phaffii. Although patent
legislation suggests free access to these yeasts, they have been distributed on a contract basis. Whereas their status
for commercial use is undetermined, the search for alternative stains for expression of recombinant protein continues.
Strains of other species of methylotrophic yeasts have been adapted, among which the genus Ogataea representatives
prevail. Despite the phylogenetic gap between the genus Ogataea and the genus Komagataella representatives,
it turned out possible to use classic vectors and promoters for expression of recombinant protein in all cases. There
exist expression systems based on other strains of the genus Komagataella as well as the genus Candida. The potential
of these microorganisms for genetic engineering is far from exhausted. Both improvement of existing expression systems
and development of new ones on the basis of strains obtained from nature are advantageous. Historically, strains
obtained on the southwest of the USA were used as expression systems up to 2009. Currently, expression systems
based on strains obtained in Thailand are gaining popularity. Since this group of microorganisms is widely represented
around the world both in nature and in urban environments, it may reasonably be expected that new expression systems
for recombinant proteins based on strains obtained in other regions of the globe will appear.

Abstract
In this study, production of fungal phytase in thermotolerant methylotrophic yeast Ogataea thermomethanolica TBRC656 employing methanol-inducible OtAOX promoter and sucrose-inducible OtMal promoter was investigated in a high cell density fed-batch fermentation. Although a similar maximum cell concentration was obtained in both expression systems, the OtMal system gave ~2-fold higher phytase activity, specific yield, production yield, volumetric productivity and specific productivity rate compared with the OtAOX system. In addition to being more efficient, the OtMal system is more flexible because sucrose or sugarcane molasses can be utilized as less expensive carbon sources instead of glycerol in batch and fed-batch stages. Phytase yields from the OtMal system produced using sucrose or sugarcane molasses are comparable with those obtained with glycerol. We estimate the cost of phytase production by the OtMal system using sucrose or sugarcane molasses to be ~85% lower than the OtAOX system.

Abstract
Phytases
are enzymes that initiate the removal of phosphate from phytate. This enzyme
has been widely utilized in animal feeding especially in the poultry industry
to enhance phosphorus intake and minimize environmental pollution. Phytases are
widely distributed in microbial, plants and animals. Supplementations of
phytase into the diets of poultry have great impact to the improvement of
poultry immune systems and increase bird weight. In addition to that, phytase
are able to improve both quantity and quality of eggs, egg mass and egg shell
quality. This review covers the classifications and distribution of phytases in
different biofactoris. In addition, it shed more light on the recent trends of
application and beneficial impact in poultry farming.

Abstract
Since the discovery of phytic acid in 1903 and phytase in 1907, extensive research has been carried out in the field of phytases, the phytic acid degradatory enzymes. Apart from forming backbone enzyme in the multimillion dollar-based feed industry, phytases extend a multifaceted role in animal nutrition, industries, human physiology, and agriculture. The utilization of phytases in industries is not effectively achieved most often due to the loss of its activity at high temperatures. The growing demand of thermostable phytases with high residual activity could be addressed by the combinatorial use of efficient phytase sources, protein engineering techniques, heterologous expression hosts, or thermoprotective coatings. The progress in phytase research can contribute to its economized production with a simultaneous reduction of various environmental problems such as eutrophication, greenhouse gas emission, and global warming. In the current review, we address the recent advances in the field of various natural as well as recombinant thermotolerant phytases, their significance, and the factors contributing to their thermotolerance.
