Abstract
Polar environments pose extreme challenges for life due to low temperatures, limited water, high radiation, and frozen landscapes. Despite these harsh conditions, numerous macro and microorganisms have developed adaptive strategies to reduce the detrimental effects of extreme cold. A primary survival tactic involves avoiding or tolerating intra and extracellular freezing. Many organisms achieve this by maintaining a supercooled state by producing small organic compounds like sugars, glycerol, and amino acids, or through increasing solute concentration. Another approach is the synthesis of ice-binding proteins, specifically antifreeze proteins (AFPs), which hinder ice crystal growth below the melting point. This adaptation is crucial for preventing intracellular ice formation, which could be lethal, and ensuring the presence of liquid water around cells. AFPs have independently evolved in different species, exhibiting distinct thermal hysteresis and ice structuring properties. Beyond their ecological role, AFPs have garnered significant attention in biotechnology for potential applications in the food, agriculture, and pharmaceutical industries. This review aims to offer a thorough insight into the activity and impacts of AFPs on water, examining their significance in cold-adapted organisms, and exploring the diversity of microbial AFPs. Using a meta-analysis from cultivation-based and cultivation-independent data, we evaluate the correlation between AFP-producing microorganisms and cold environments. We also explore small and large-scale biotechnological applications of AFPs, providing a perspective for future research.

Freezing-enhanced oxidation of iodide by hydrogen peroxide in the presence of antifreeze proteins from the Arctic yeast Leucosporidium sp.AY30. ENVIRONMENTAL RESEARCH 2022; 212:113233.

Abstract
Ice-binding proteins (IBPs), originating from Arctic or Antarctic microorganisms, have freeze-inhibiting characteristics, allowing these organisms to survive in polar regions. Despite their significance in polar environments, the mechanism through which IBPs affect the chemical reactions in ice by controlling ice crystal formation has not yet been reported. In this study, a new mechanism for iodide (I-) activation into triiodide (I3-), which is the abundant iodine species in seawater, by using hydrogen peroxide (H2O2) in a frozen solution with IBPs was developed. A significant enhancement of I- activation into I3- was observed in the presence of Arctic-yeast-originating extracellular ice-binding glycoprotein (LeIBP) isolated from Leucosporidium sp. AY30, and a further increase in the I3- concentration was observed with the introduction of H2O2 to the frozen solution (25 times higher than in the aqueous solution after 24 h of reaction). The reaction in the ice increased with an increase in LeIBP concentration. The in-situ pH measurement in ice using cresol red (CR) revealed protons accumulated in the ice grain boundaries by LeIBP. However, the presence of LeIBP did not influence the acidity of the ice. The enhanced freeze concentration effect of H2O2 by LeIBP indicated that larger ice granules were formed in the presence of LeIBP. The results suggest that LeIBP affects the formation and morphology of ice granules, which reduces the total volume of ice boundaries throughout the ice. This leads to an increased local concentration of I- and H2O2 within the ice grain boundaries. IBP-assisted production of gaseous iodine in a frozen environment provides a previously unrecognized formation mechanism of active iodine species in the polar regions.

Abstract
There are a large number of active cold-adapted microorganisms in the perennial cold environment. Due to their high-efficiency and energy-saving catalytic properties, cold-adapted microorganisms have become valuable natural resources with potential in various biological fields. In this study, a series of cold response strategies for microorganisms were summarized. This mainly involves the regulation of cell membrane fluidity, synthesis of cold adaptation proteins, regulators and metabolic changes, energy supply, and reactive oxygen species. Also, the potential of biocatalysts produced by cold-adapted microorganisms including cold-active enzymes, ice-binding proteins, polyhydroxyalkanoates, and surfactants was introduced, which provided a guidance for expanding its application values. Overall, new insights were obtained on response strategies of microorganisms to cold environments in this review. This will deepen the understanding of the cold tolerance mechanism of cold-adapted microorganisms, thus promoting the establishment and application of low-temperature biotechnology.

Abstract
Ice accretion on surfaces can cause serious damages and economic losses in industries and civilian facilities. Antifreeze proteins (AFPs) as evolutionary adaptation products of organisms to cold climates, provide solutions for alleviating icing problems. In this work, a chimeric protein Mfp-AFP was rationally designed combining mussel-inspired adhesive domain with Tenebrio molitor-derived antifreeze protein domain. Expectedly, the multifunctional Mfp-AFP can lower the freezing point of water and inhibit ice recrystallization. The chimeric protein could also readily modify diverse solid surfaces due to the adhesive domain containing Dopa, and resist frosting and delay ice formation due to the beetle-derived antifreeze fragment. Moreover, Mfp-AFP coatings display excellent biocompatibility proved by cytocompatibility and hemolysis assays. Here, the designed multifunctional protein coatings provide an alternative strategy for fabricating anti-icing surfaces.

Abstract
The antimicrobial peptide PMAP-36 is a cationic peptide derived from porcine myeloid. The N-terminally paired lysine of PMAP-36 was substituted with tryptophan, and the C-terminal hydrophobic tail was deleted, thereby obtaining the antimicrobial peptide PRW4. PRW4 is a α-helical antimicrobial peptide with broad-spectrum antimicrobial activity. In this study, PRW4 was fused to the 6× His-Trx, and the fusion protein was successfully expressed in Pichia pastoris GS115 from the vector pPICZαA. The maximal induction of recombinant protein occurred in the presence of 1% methanol after 96 h at pH 6.0. After purification by a Ni-NTA resin column and digestion by enterokinase protease, 15 mg of recombinant PRW4 with a purity of 90% was obtained from 1 L of fermentation culture. The results indicated that recombinant PRW4 had similar antimicrobial activity as synthetic PRW4 against bacteria such as Escherichia coli ATCC 25922, Escherichia coli UB 1005, Salmonella typhimurium C7731, Salmonella typhimurium 7913, Salmonella typhimurium ATCC 14028, Staphylococcus aureus ATCC 29213, Staphylococcus epidermidis ATCC 12228, and Streptococcus faecalis ATCC 29212. We have successfully expressed PRW4 in P. pastoris, and this work provides a reference for the production of modified antimicrobial peptides in P. pastoris.

Abstract
We examined the effect of ice‐binding protein derived from Leucosporidium (LeIBP) on the cryopreservation of bull semen and compared it with that derived from previously reported Antifreeze Protein III (AFPIII). Six concentrations of LeIBP (10–1 ~ 104 μg/ml) and AFPIII (10–1 ~ 104 μg/ml) were added to the bull semen extender, respectively. Sperm kinematic parameters were measured to examine sperm toxicity and cryopreserved sperm quality. Measures of antioxidant activity such as superoxide dismutase (SOD), reduced glutathione/oxidative glutathione (GSH/GSSG), and total antioxidant capacity (TAC) were analysed to identify the effect of LeIBP on sperm quality. In addition, sperm viability was analysed using a flow cytometer and fluorescence microscope by SYBR14/PI staining. The results showed that the LeIBP groups (0.1, 1 and 10 μg/ml) were less toxic, and the quality of the sperm were dramatically improved in the extenders containing 0.1 μg/ml LeIBP among concentrations of LeIBP and AFPIII. The SOD activity of LeIBP was greater than that of AFPIII and control. In addition, sperm viability was enhanced in the LeIBP‐treated group. In summary, LeIBP is a useful cryoprotective adjuvant for bull sperm cryopreservation, and the most efficient concentration of LeIBP is 0.1 μg/ml.

Abstract
Ice-binding proteins (IBPs) facilitate organism survival under extreme conditions by inhibiting thermal hysteresis and ice recrystallization. IBPs have been widely used as cryoprotectants to cryopreserve mammalian gametes and embryos. In the present study, we evaluated the protective effects of an Arctic yeast, Leucosporidium sp. AY30 derived ice-binding protein (LeIBP), on the vitrification of bovine metaphase II (MII) oocytes and embryos. When oocytes and embryos were frozen using the two-step vitrification method, the survival rate was significantly increased in the presence of LeIBP. The LeIBP supplementation decreased the levels of intracellular reactive oxygen species (ROS) and enhanced mitochondrial functions in the vitrified-warmed oocytes. Furthermore, LeIBP improved the developmental potential and suppressed apoptosis of the embryos derived from vitrified-warmed oocytes. Collectively, these data indicate that LeIBP can be used as a promising cryoprotectant to prevent cryoinjury during vitrification in bovine oocytes.

Abstract
More than 80% of Earth’s surface is exposed periodically or continuously to temperatures below 5 °C. Organisms that can live in these areas are called psychrophilic or psychrotolerant. They have evolved many adaptations that allow them to survive low temperatures. One of the most interesting modifications is production of specific substances that prevent living organisms from freezing. Psychrophiles can synthesize special peptides and proteins that modulate the growth of ice crystals and are generally called ice binding proteins (IBPs). Among them, antifreeze proteins (AFPs) inhibit the formation of large ice grains inside the cells that may damage cellular organelles or cause cell death. AFPs, with their unique properties of thermal hysteresis (TH) and ice recrystallization inhibition (IRI), have become one of the promising tools in industrial applications like cryobiology, food storage, and others. Attention of the industry was also caught by another group of IBPs exhibiting a different activity—ice-nucleating proteins (INPs). This review summarizes the current state of art and possible utilizations of the large group of IBPs.

Abstract
During the freezing process, ice crystal formation leads to the deterioration in physicochemical properties and networks of gluten proteins. The cryoprotective effects of recombinant carrot ( Daucus carota) antifreeze protein (rCaAFP), type II antifreeze protein from Epinephelus coioides (rFiAFP), and Tenebrio molitor antifreeze protein (rTmAFP) produced from Pichia pastoris GS115 on hydrated gluten, glutenin, and gliadin during freezing were investigated. The thermal hysteresis (TH) activity and ice crystals' morphology modification ability of recombinant antifreeze proteins (rAFPs) were analyzed by differential scanning calorimetry (DSC) and cryomicroscope, respectively. The freezing and melting properties, water state, rheological properties, and microstructure of hydrated gluten proteins were studied by DSC, low field nuclear magnetic resonance, rheometer, and scanning electron microscopy, respectively. The rTmAFP exhibited strongest TH activity and ice crystals' morphology modification ability, followed by rFiAFP and rCaAFP. The addition of the three rAFPs caused freezing hysteresis and weakened the damage of freezing to the networks of hydrated gluten, glutenin, and gliadin. During freezing, the cryoprotective effects of the three rAFPs on the freezable water content, water mobility and distribution, and rheological properties of hydrated gluten were achieved by protecting these corresponding properties of hydrated glutenin. Among the three rAFPs, rTmAFP was most effective in the cryoprotective activities on hydrated gluten proteins during freezing. The results demonstrate the potential of these rAFPs, especially rTmAFP, to preserve the above properties of hydrated gluten proteins during the freezing process.

Abstract
Pichia pastoris has been one of the most successful heterologous overexpression systems in generating proteins for large-scale production through high-cell-density fermentation. However, optimizing conditions of the large-scale high-cell-density fermentation for biochemistry and industrialization is usually a laborious and time-consuming process. Furthermore, it is often difficult to produce authentic proteins in large quantities, which is a major obstacle for functional and structural features analysis and industrial application. For these reasons, we have developed a protocol for efficient demonstration-scale high-cell-density fermentation of P. pastoris, which employs a new methanol-feeding strategy-biomass-stat strategy and a strategy of increased air pressure instead of pure oxygen supplement. The protocol included three typical stages of glycerol batch fermentation (initial culture phase), glycerol fed-batch fermentation (biomass accumulation phase), and methanol fed-batch fermentation (induction phase), which allows direct online-monitoring of fermentation conditions, including broth pH, temperature, DO, anti-foam generation, and feeding of glycerol and methanol. Using this protocol, production of the recombinant β-xylosidase of Lentinula edodes origin in 1000-L scale fermentation can be up to ~900 mg/L or 9.4 mg/g cells (dry cell weight, intracellular expression), with the specific production rate and average specific production of 0.1 mg/g/h and 0.081 mg/g/h, respectively. The methodology described in this protocol can be easily transferred to other systems, and eligible to scale up for a large number of proteins used in either the scientific studies or commercial purposes.

Abstract
Ice-binding protein (IBPs) protect cells from cryo-injury during cryopreservation by inhibiting ice recrystallization (IR), which is a main cause of cell death. In the present study, we employed two IBPs, one, designated LeIBP from Arctic yeast, and the other, designated FfIBP from Antarctic sea ice bacterium, in the cryopreservation of three economically valuable marine microalgae, Isochrysis galbana, Pavlova viridis, and Chlamydomonas coccoides. Both of the IBPs showed IR inhibition in f/2 medium containing 10% DMSO, indicating that they retain their function in freezing media. Microalgal cells were frozen in 10% DMSO with or without IBP. Post-thaw viability exhibited that the supplementation of IBPs increased the viability of all cryopreserved cells. LeIBP was effective in P. viridis and C. coccoides, while FfIBP was in I. galbana. The cryopreservative effect was more drastic with P. viridis when 0.05 mg/mL LeIBP was used. These results clearly demonstrate that IBPs could improve the viability of cryopreserved microalgal cells.

Abstract
Antifreeze proteins (AFPs) are biological antifreezes with unique properties, including thermal hysteresis(TH),ice recrystallization inhibition(IRI),and interaction with membranes and/or membrane proteins. These properties have been utilized in the preservation of biological samples at low temperatures. Here, we review the structure and function of marine-derived AFPs, including moderately active fish AFPs and hyperactive polar AFPs. We also survey previous and current reports of cryopreservation using AFPs. Cryopreserved biological samples are relatively diverse ranging from diatoms and reproductive cells to embryos and organs. Cryopreserved biological samples mainly originate from mammals. Most cryopreservation trials using marine-derived AFPs have demonstrated that addition of AFPs can improve post-thaw viability regardless of freezing method (slow-freezing or vitrification), storage temperature, and types of biological sample type.

Scaling-up Fermentation of Pichia pastoris to demonstration-scale using new methanol-feeding strategy and increased air pressure instead of pure oxygen supplement. Sci Rep 2016; 6:18439.

Abstract
Scaling-up of high-cell-density fermentation (HCDF) of Pichia pastoris from the lab or pilot scale to the demonstration scale possesses great significance because the latter is the final technological hurdle in the decision to go commercial. However, related investigations have rarely been reported. In this paper, we study the scaling-up processes of a recombinant P. pastoris from the pilot (10 to 100-L) to the demonstration (1,000-L) scales, which can be used to convert 7-β-xylosyl-10-deacetyltaxol into 10-deacetyltaxol by the β-xylosidase for semi-synthesis of Taxol. We demonstrated that a pure oxygen supplement can be omitted from the HCDF if the super atmospheric pressure was increased from 0.05 to 0.10 ± 0.05 MPa, and we developed a new methanol feeding biomass-stat strategy (0.035 mL/g/h) with 1% dissolved oxygen and 100 g/L initial induction biomass (dry cell weight). The scaling-up was reproducible, and the best results were obtained from the 1,000-L scale, featuring a shorter induction time and the highest enzyme activities and productions, respectively. The specific growth and specific production rates were also determined. This study lays a solid foundation for the commercial preparation of 10-deacetyltaxol through the recombinant yeast. It also provides a successful paradigm for scaling-up HCDF of P. pastoris to the demonstration scale.

Abstract
STUDY QUESTION Can antifreeze proteins (AFPs) from three different sources improve the efficacy of mouse oocyte vitrification? SUMMARY ANSWER Treatment with AFPs can improve both murine oocyte quality and embryo development, and reduce reactive oxygen species (ROS) production in vitrified-warmed oocytes. WHAT IS KNOWN ALREADY A previous study discovered that vitrification of immature oocytes and 2-cell stage embryos of mice augmented with antifreeze glycoproteins at 40 mg/ml dramatically improved the morphological integrity of the samples, suggesting that AFPs have the ability to inhibit ice formation and stabilize the plasma membrane. STUDY DESIGN, SIZE, DURATION Metaphase II oocytes were obtained from 4-week-old BD-F1 mice. AFPs from bacteria (Flavobacterium frigoris ice-binding protein (FfIBP)), yeast (Glaciozyma sp. ice-binding protein (LeIBP)) and fish (Type III AFP) were added to the vitrification and warming solutions individually. Survival and development, meiotic spindle organization, intracellular ROS, mitochondrial activity, DNA double-strand breaks (DSBs) and repair of damaged DNA were analyzed. PARTICIPANTS/MATERIALS, SETTING, METHODS Vitrification of oocytes was performed with the CryoTop (equilibration solution: 7.5% ethylene glycol (EG) and 7.5% 1,2-propandiol (PROH) for 5 min; vitrification solution: 15% EG, 15% PROH and 0.5 M sucrose for 1 min). Warming was performed in three steps with decreasing concentrations of sucrose (1.0, 0.5 and 0.25 M sucrose). MAIN RESULTS AND THE ROLE OF CHANCE AFP treatment can improve murine oocyte quality and embryo development. Survival rates, cleavage rates and blastocyst rates (blastocyst per cleaved and per survived oocytes) of oocytes in AFP-treated groups were significantly higher than those in the control group [75.0, 89.0, 90.0 and 85.0% for survival rate (P = 0.012); 58.7, 89.0, 87.8 and 81.2% for cleavage rate (P = 0.003); 52.3, 87.7, 78.5 and 76.8% for blastocyst per cleaved oocytes (P < 0.01); 30.7, 78.0, 68.9 and 62.4% for blastocyst per survived oocytes (P < 0.01) in control, FfIBP, LeIBP and Type III AFP-treated groups, respectively]. The mean (±SD) number of apoptotic blastomeres per blastocyst was significantly lower in AFP-treated groups than in the control group (9.1 ± 1.0, 2.0 ± 1.7, 2.3 ± 1.2 and 2.7 ± 2.4 in control, FfIBP, LeIBP and Type III AFP-treated groups, respectively, P = 0.040). FfIBP treatment was the most effective in maintaining normal meiotic spindle organization and chromosome alignment (52.0, 92.0, 80.0 and 83.0% in control, FfIBP, LeIBP and Type III AFP-treated groups, respectively, P < 0.01). Intracellular ROS levels (mean ± SD) significantly decreased in the AFP-treated groups (17.0 ± 11.2, 8.4 ± 8.2, 10.3 ± 6.4 and 11.6 ± 12.3 in control, FfIBP, LeIBP and Type III AFP-treated groups, respectively, P < 0.01), and the FfIBP and LeIBP groups had significantly lower DNA DSBs, compared with controls (65.2, 30.8, 44.4 and 55.8% in control, FfIBP, LeIBP and Type III AFP-treated groups, respectively, P < 0.01). LIMITATIONS, REASONS FOR CAUTION The origins of FfIBP and LeIBP were bacteria and yeast, respectively. Therefore, treatment of human oocytes and embryos with these AFPs should be tested before clinical application. WIDER IMPLICATIONS OF THE FINDINGS After further research, AFPs can potentially be applied to human oocyte cryopreservation to improve the efficacy of vitrification.

A non-ionic surfactant reduces the induction time and enhances expression levels of bubaline somatotropin in Pichia pastoris. Mol Biol Rep 2014; 41:855-63.

Abstract
This study describes a simple approach for enhanced secretory expression of bubaline somatotropin (BbST) in the methylotropic yeast Pichia pastoris. A Mut(s) Pichia transformant carrying multi-copy, non-codon optimized BbST cDNA sequence, expressed and secreted the recombinant protein into the culture medium to a level of 25 % of the total proteins in the culture supernatant, after 120 h of induction. Inclusion of polysorbate-80 in the inducing medium resulted in a significant improvement in the BbST expression (up to 45 % of the total culture supernatant proteins) with concomitant reduction in the induction time to 48 h. The amount of BbST obtained was 148 mg/L, which was around fivefold higher than that obtained without the surfactant. BbST was purified to near homogeneity by FPLC on Q-sepharose FF anion-exchange column. Protein authenticity was judged by SDS-PAGE and western blot analyses. A bioassay based on proliferation of Nb2 rat lymphoma cell lines confirmed that the purified, recombinant BbST is biologically active. Use of polysorbate-80 in combination with methanol, during the induction phase, is likely to have general applicability in lowering the induction time and enhancing the secretory expression of other commercially important proteins in Mut(s) strains of P. pastoris.

Abstract
A genetically engineered strain of Pichia pastoris expressing S-adenosylmethionine synthetase gene from Saccharomyces cerevisiae under the control of AOX 1 promoter was developed. Induction of recombinant strain with 1% methanol resulted in the expression of SAM2 protein of ~ 42 kDa, whereas control GS115 showed no such band. Further, the recombinant strain showed 17-fold higher enzyme activity over control. Shake flask cultivation of engineered P. pastoris in BMGY medium supplemented with 1% L-methionine yielded 28 g/L wet cell weight and 0.6 g/L S-adenosylmethionine, whereas control (transformants with vector alone) with similar wet cell weight under identical conditions accumulated 0.018 g/L. The clone cultured in the bioreactor containing enriched methionine medium showed increased WCW (117 g/L) as compared to shake flask cultures and yielded 2.4 g/L S-adenosylmethionine. In spite of expression of SAM 2 gene up to 90 h, S-adenosylmethionine accumulation tended to plateau after 72 h, presumably because of the limited ATP available in the cells at stationery phase. The recombinant P pastoris seems promising as potential source for industrial production of S-adenosylmethionine.
