Hybrid machine learning model based predictions for properties of poly(2-hydroxyethyl methacrylate)-poly(vinyl alcohol) composite cryogels embedded with bacterial cellulose. J Chromatogr A 2024; 1727:464996. [PMID: 38763087 DOI: 10.1016/j.chroma.2024.464996] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 05/10/2024] [Accepted: 05/13/2024] [Indexed: 05/21/2024]
Abstract
Supermacroporous composite cryogels with enhanced adjustable functionality have received extensive interest in bioseparation, tissue engineering, and drug delivery. However, the variations in their components significantly impactfinal properties. This study presents a two-step hybrid machine learning approach for predicting the properties of innovative poly(2-hydroxyethyl methacrylate)-poly(vinyl alcohol) composite cryogels embedded with bacterial cellulose (pHEMA-PVA-BC) based on their compositions. By considering the ratios of HEMA (1.0-22.0 wt%), PVA (0.2-4.0 wt%), poly(ethylene glycol) diacrylate (1.0-4.5 wt%), BC (0.1-1.5 wt%), and water (68.0-96.0 wt%) as investigational variables, overlay sampling uniform design (OSUD) was employed to construct a high-quality dataset for model development. The random forest (RF) model was used to classify the preparation conditions. Then four models of artificial neural network, RF, gradient boosted regression trees (GBRT), and XGBoost were developed to predict the basic properties of the composite cryogels. The results showed that the RF model achieved an accurate three-class classification of preparation conditions. Among the four models, the GBRT model exhibited the best predictive performance of the basic properties, with the mean absolute percentage error of 16.04 %, 0.85 %, and 2.44 % for permeability, effective porosity, and height of theoretical plate (1.0 cm/min), respectively. Characterization results of the representative pHEMA-PVA-BC composite cryogel showed an effective porosity of 81.01 %, a permeability of 1.20 × 10-12 m2, and a range of height of theoretical plate between 0.40-0.49 cm at flow velocities of 0.5-3.0 cm/min. These indicate that the pHEMA-PVA-BC cryogel was an excellent material with supermacropores, low flow resistance and high mass transfer efficiency. Furthermore, the model output demonstrates that the alteration of the proportions of PVA (0.2-3.5 wt%) and BC (0.1-1.5 wt%) components in composite cryogels resulted in significant changes in the material basic properties. This work represents an attempt to efficiently design and prepare target composite cryogels using machine learning and providing valuable insights for the efficient development of polymers.

J Chromatogr B Analyt Technol Biomed Life Sci 2024; 1234:124027.

Abstract
This study investigated the purification of bromelain obtained from pineapple fruit using a new adsorbent for immobilized metal ion affinity chromatography (IMAC), with chlorophyll obtained from plant leaves as a chelating agent. The purification of bromelain was evaluated in batches from the crude extract of pineapple pulp (EXT), and the extract precipitated with 50 % ammonium sulfate (EXT.PR), the imidazole buffer (200 mM, pH 7.2) being analyzed and sodium acetate buffer, pH 5.0 + 1.0 NaCl as elution solutions. All methods tested could separate forms of bromelain with molecular weights between ±21 to 25 kDa. Although the technique using EXT.PR stood out in terms of purity, presenting a purification factor of around 3.09 ± 0.31 for elution with imidazole and 4.23 ± 0.12 for acetate buffer solution. In contrast, the EXT methods obtained values between 2.44 ± 0.23 and 3.21 ± 0.74 for elution with imidazole and acetate buffer, respectively, for purification from EXT.PR has lower yield values (around 5 %) than EXT (around 15 %). The number of steps tends to reduce yield and increase process costs, so the purification process in a monolithic bed coupled to the chromatographic system using the crude extract was evaluated. The final product obtained had a purification factor of 6, with a specific enzymatic activity of 59.61 ± 0.00 U·mg-1 and a yield of around 39 %, with only one band observed in the SDS-PAGE electrophoresis analysis, indicating that the matrix produced can separate specific proteins from the total fraction in the raw material. The IMAC matrix immobilized with chlorophyll proved promising and viable for application in protease purification processes.

Abstract
Enzyme immobilization has been reported as a promising approach to improving parameters such as thermal stability, pH and reusability. In this study, a polyacrylamide cryogel functionalized with L-phenylalanine was prepared to be used in the adsorption of β-glucosidase from Thermoascus aurantiacus, aiming at its separation and also its immobilization on the cryogel matrix. The enzyme was produced by solid state fermentation. First, the adsorption was studied as a function of the pH and the resulting yield (Y, %) and purification factor (PF, dimensionless) were determined (1.57-5.13 and 64.19-91.20, respectively). The PF and yield from eluate samples obtained at pH 3.0 were the highest (5.13 and 91.20, respectively). Then, β-glucosidase was immobilized on the hydrophobic cryogel and the recovery activities (%) were determined as a function of temperature and in the presence of different saline solutions. The values ranged from 14.45 to 45.97. As expected, salt type and ionic strength affected the activity remained in the immobilized β-glucosidase. The average bioreactor activity was 39.9 U/g of dry cryogel and its operational stability was measured, with no decrease in activity being observed during seven cycles. Kinetic parameters of free and immobilized enzyme were determined according to different models.

Abstract
Changes in microbial community structure are widely known to occur after soil amendment with low-molecular-weight organic compounds; however, there is little information on concurrent changes in soil microbial functional diversity and enzyme activities, especially following sorbitol and mannitol amendment. Soil microbial functional diversity and enzyme activities can be impacted by sorbitol and mannitol, which in turn can alter soil fertility and quality. The objective of this study was to investigate the effects of sorbitol and mannitol addition on microbial functional diversity and enzyme activities. The results demonstrated that sorbitol and mannitol addition altered the soil microbial community structure and improved enzyme activities. Specifically, the addition of sorbitol enhanced the community-level physiological profile (CLPP) compared with the control, whereas the CLPP was significantly inhibited by the addition of mannitol. The results of a varimax rotated component matrix demonstrated that carbohydrates, polymers, and carboxylic acids affected the soil microbial functional structure. Additionally, we found that enzyme activities were affected by both the concentration and type of inputs. In the presence of high concentrations of sorbitol, the urease, catalase, alkaline phosphatase, β-glucosidase, and N-acetyl-β-d-glucosaminidase activities were significantly increased, while invertase activity was decreased. Similarly, this increase in invertase, catalase, and alkaline phosphatase and N-acetyl-β-d-glucosaminidase activities was especially evident after mannitol addition, and urease activity was only slightly affected. In contrast, β-glucosidase activity was suppressed at the highest concentration. These results indicate that microbial community diversity and enzyme activities are significantly affected by soil amendment with sorbitol and mannitol.

Abstract
Immobilized metal-ion affinity chromatography (IMAC) has been developed for the rapid isolation and purification of recombinant proteins. In this chapter, megaporous cryogels were synthesized having metal-ion affinity functionality, and their adsorptive properties were investigated. These cryogels have large pore sizes ranging from 10 to 100 μm with corresponding porosities between 80 and 90%. The synthesized IMAC-cryogel had a total ligand density of 770 μmol/g. Twelve milligram of a His6-tagged protein (NAD(P)H-dependent 2-cyclohexen-1-one-reductase) can be purified from a crude cell extract per gram of IMAC-cryogels. The protein binding capacity is increased with higher degrees of grafting, although a slight decrease in column efficiency may result. This chapter provides methodologies for a rapid single-step purification of recombinant His6-tagged proteins from crude cell extracts using IMAC-cryogels.

Abstract
Cryogels are highly elastic three-dimensional materials consisting of a network of interconnected macropores. This unique morphology combined with high mechanical and chemical stability provides excellent mass flow properties. The matrices are synthesized at subzero temperatures from almost any gel-forming precursor. The main fields of application are in biotechnology as 3D-scaffold for cell cultivation, and tissue engineering, or bioseparation as chromatographic media for the separation and purification of biomolecules. This chapter briefly highlights the preparation, properties, and application of these materials.

Abstract
Megaporous cryogels with metal-ion affinity functionality, which possess enhanced protein-binding ability, were synthesized and their properties were investigated. These highly porous materials (pore sizes up to 100 μm) allowed the direct capture of a recombinant His(6)-tagged protein from a partially clarified extract. The total ligand density of the material was found to be 770 μmol/g. Application of a partially clarified cell extract in order to recover a His(6)-tagged protein (NAD(P)H-dependent 2-cyclohexen-1-one-reductase) yielded 12 mg of highly purified recombinant product per gram of adsorbent. Increased dynamic binding capacities were observed upon larger degrees of grafting, although some reduction in the quality of the system hydrodynamics was also observed. Nevertheless, these immobilized metal-ion affinity cryogels show potential for a convenient single-step purification of recombinant proteins from raw cell extracts without the need for laborious pre-chromatographic sample clean-up procedures.

Abstract
The concept of biocompatibility with reference to chromatographic stationary phases for separation of biomolecules (including proteins and peptides) is introduced. Biocompatible is a characteristic that indicates resistance to nonspecific adsorption of biomolecules and preservation of their structures and biochemical functions. Two types of biocompatible polymeric monoliths [i. e., polyacrylamide- and poly(meth)acrylate-based monoliths] used for protein and peptide separations are reviewed in detail, with emphasis on size exclusion, ion exchange, and hydrophobic interaction chromatographic modes. Biocompatible monoliths for enzyme reactors are also included. The two main synthetic approaches to produce biocompatible monoliths are summarized, i. e., surface modification of a monolith that is not inherently biocompatible and direct copolymerization of hydrophilic monomers to form a biocompatible monolith directly. Integration of polyethylene glycol into the poly(meth)acrylate monolith network is becoming popular for reduction of non-specific protein interactions.

Abstract
This communication presents an effective method for isolating adenosine triphosphate (ATP) from a yeast fermentation broth using an anion-exchange supermacroporous cryogel column at high flow velocities. The breakthrough and elution behaviors of pure ATP in the cryogel bed were investigated at flow velocities of 2, 5, and 10 cm/min and the ATP binding capacities were determined. Then the ATP-containing yeast fermentation broth was employed as the test feedstock and various chromatographic runs were conducted to isolate ATP by the cryogel at different high flow velocities. The ATP samples obtained were analyzed quantitatively by HPLC. The results showed that even at a flow velocity of 5 or 10 cm/min, a product purity of 97.4 or 98.0% can be achieved, illustrating the potential of the present method for separation of high-purity ATP directly from fermentation feedstock at high flow velocities.

Abstract
A novel separation method was developed to isolate directly cytidine triphosphate (CTP) from fermentation broth of yeast using anion-exchange supermacroporous cryogel. The anion-exchange cryogel with tertiary amine groups was prepared by graft polymerization. The breakthrough characteristics and elution performance of pure CTP in the cryogel bed were investigated experimentally and the CTP binding capacity was determined. Then the separation experiments of CTP from crude fermentation broth of yeast using the cryogel column were carried out using deionized water and 0.01 M HCl as washing buffer, respectively. The chromatographic behavior was monitored and analyzed. The purity and concentration of the obtained CTP in these processes were determined quantitatively by HPLC. The maximal purity of CTP obtained at the condition of 0.01 M HCl as washing buffer and 0.5 M NaCl in 0.01 M HCl as elution buffer reached 93%.

Abstract
Graft polymerization of monomer chains with expected functional groups onto the matrix pore surfaces by initiator is an effective approach for introducing ion-exchange groups to cryogel matrix to get anion- or cation-exchange supermacroporous cryogels. In this work, a novel cation-exchange cryogel with sulfo binding groups was prepared by grafting of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) onto polyacrylamide-based cryogels in glass columns. The grafting polymerization was achieved in an in-situ manner which was performed by pumping the initiator and the reactive solution of graft monomer with sulfo binding groups directly through a cryogel bed pre-produced in a glass column under frozen condition. The axial liquid dispersion characteristics within the monolithic cryogel beds before and after the in-situ polymerization were compared by measuring residence time distributions (RTDs) at various liquid flow rates using tracer pulse-response method. Microstructure morphology of pores within cryogels was analyzed by scanning electron microscopy (SEM). Chromatography of lysozyme was carried out to reveal the protein breakthrough and elution characteristics in the obtained cryogel beds.
