Fabrication of lipase-loaded particles by coacervation with chitosan. Food Chem 2022; 385:132689.

Abstract
Coacervation of the lipase from Aspergillus oryzae (AOL) with chitosan was a feasible way to fabricate lipase-loaded particles and the optimum conditions were phase separation pH 5.5, chitosan to AOL mass ratio 1:5, and temperature 25 °C in the absence of NaCl, which conferred an AOL loading efficiency of up to 95.48% and activity recovery of 69.60%. The AOL-chitosan coacervates were highly porous and more susceptible to weight loss upon heating. Coacervation with chitosan increased the activity of AOL and shifted its optimum pH from 7.0 to 6.0, but exerted no effect on its optimum temperature (45 °C). Thermal deactivation kinetics analysis revealed that the coacervated AOL was more thermal stable, while the Michaelis-Menten kinetics analysis indicated that coacervation with chitosan increased the Vmax of AOL by 2.4 folds, but decreased its substrate affinity by 3.6 folds. Hence, the AOL-chitosan coacervates are potential in the construction of Pickering emulsion-based lipase catalysis systems.

Expression and characterization of a novel lipase from Bacillus licheniformis NCU CS-5 for application in enhancing fatty acids flavor release for low-fat cheeses. Food Chem 2022; 368:130868. [PMID: 34438173 DOI: 10.1016/j.foodchem.2021.130868] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2021] [Revised: 08/12/2021] [Accepted: 08/12/2021] [Indexed: 01/10/2023]
Abstract
A novel lipase from Bacillus licheniformis NCU CS-5 was expressed in different Escherichia coli cells. The recombinant enzyme achieved a high activity (161.74 U/mL) with protein concentration of 0.27 mg/mL under optimal conditions at the large-scale expression of 12 h. The recombinant lipase showed optimal activity at 40 ℃ and pH 10.0, and maintained more than 80% relative activity after 96 h of incubation at pH 9.0-10.0. This typical alkaline lipase was activated under medium temperature conditions (30 and 45 ℃ for 96 h). The lipase exhibited a degree of adaptability in various organic solvents and metal ions, and showed high specificity towards triglycerides with short and medium chain fatty acids. Among different substrates, the lipase showed the strongest binding affinity towards pNPP (Km = 0.674 mM, Vmax = 950.196 μM/min). In the experiments of its application in enhancing fatty acids flavor release for low-fat cheeses, the lipase was found to hydrolyze cheeses and mainly increase the contents of butyric acid, hexanoic acid, caprylic acid and decanoic acid. The results from NMR and GC provided the possibility of enhancing fatty acids flavor released from low-fat cheeses by the lipolysis method.

Abstract
Aspergillus niger MH078571.1 and A. niger MH079049.1 were identified previously as the two highest Aspergillus niger strains producing lipase. Biochemical characterizations of lipase activity and stability for these two strains were examined and revealed that the optimal temperature is 45 °C at pH 8for A. niger MH078571.1 and 55 °C for MH079049.1. The lipase production of both strains was studied on medium contains waste oil, as a cheap source to reduce the industrial cost, showed that the optimal incubation period for the enzyme production is 3 days. Moreover, an experiment on lipase activates in organic solvents demonstrated that 50% of acetone is the best solvent for the two strains. In the presence of surfactants, 0.1% of tween 80 surfactant showed the best lipase activities. Furthermore, Mg2+ and Zn2+ ions enhanced the lipase activity of A. niger MH078571.1, while Na2+ and Cu2+ enhanced the enzyme activity of A. niger MH079049.1. Lipase activity was also tested for industrial applications such as integrating it with different detergents. Maximum lipase activity was obtained with 1% of Omo as a powder detergent for both strains. In liquid detergent, 0.1% of Fairy showed maximum lipase activity in A. niger MH078571.1, while the lipase in A. niger MH079049.1 was more effective in 1% of Lux. Moreover, the degradation of natural animal fat with crude enzyme was tested using chicken and sheep fats. The results showed that more than 90% of fats degraded after 5 days of the incubation period.

Gene Expression, Biochemical Characterization of a sn-1, 3 Extracellular Lipase From Aspergillus niger GZUF36 and Its Model-Structure Analysis. Front Microbiol 2021; 12:633489.

Abstract
In this study, a sn-1, 3 extracellular lipases from Aspergillus niger GZUF36 (PEXANL1) was expressed in Pichia pastoris, characterized, and the predicted structural model was analyzed. The optimized culture conditions of P. pastoris showed that the highest lipase activity of 66.5 ± 1.4 U/mL (P < 0.05) could be attained with 1% methanol and 96 h induction time. The purified PEXANL1 exhibited the highest activity at pH 4.0 and 40°C temperature, and its original activity remained unaltered in the majority of the organic solvents (20% v/v concentration). Triton X-100, Tween 20, Tween 80, and SDS at a concentration of 0.01% (w/v) enhanced, and all the metal ions tested inhibited activity of purified PEXANL. The results of ultrasound-assisted PEXANL1 catalyzed synthesis of 1,3-diaglycerides showed that the content of 1,3-diglycerides was rapidly increased to 36.90% with 25 min of ultrasound duration (P < 0.05) and later decreased to 19.93% with 35 min of ultrasound duration. The modeled structure of PEXANL1 by comparative modeling showed α/β hydrolase fold. Structural superposition and molecular docking results validated that Ser162, His274, and Asp217 residues of PEXANL1 were involved in the catalysis. Small-angle X-ray scattering analysis indicated the monomer properties of PEXANL1 in solution. The ab initio model of PEXANL1 overlapped with its modeling structure. This work presents a reliable structural model of A. niger lipase based on homology modeling and small-angle X-ray scattering. Besides, the data from this study will benefit the rational design of suitable crystalline lipase variants in the future.

Abstract
Background Rhizopus species is among the most well-known lipase producers, and its enzyme is suitable for use in many industrial applications. Our research focuses on the production of lipase utilizing waste besides evaluating its applications. Results An extracellular lipase was partially purified from the culture broth of Rhizopus oryzae R1 isolate to apparent homogeneity using ammonium sulfate precipitation followed by desalting via dialysis. The partially purified enzyme was non-specific lipase and the utmost activity was recorded at pH 6, 40 °C with high stability for 30 min. The constants Km and Vmax, calculated from the Lineweaver-Burk plot, are 0.3 mg/mL and 208.3 U/mL, respectively. Monovalent metal ions such as Na+ (1 and 5 mM) and K+ (5 mM) were promoters of the lipase to enhance its activity with 110, 105.5, and 106.5%, respectively. Chitosan was used as a perfect support for immobilization via both adsorption and cross-linking in which the latter method attained immobilization efficiency of 99.1% and reusability of 12 cycles. The partially purified enzyme proved its ability in forming methyl oleate (biodiesel) through the esterification of oleic acid and transesterification of olive oil. Conclusion The partially purified and immobilized lipase from Rhizopus oryzae R1 approved excellent efficiency, reusability, and a remarkable role in detergents and biodiesel production.

Gene cloning, expression, purification and characterization of a sn-1,3 extracellular lipase from Aspergillus niger GZUF36. Journal of Food Science and Technology 2020; 57:2669-2680.

Abstract
Sn-1,3 extracellular Aspergillus niger GZUF36 lipase (EXANL1) has wide application potential in the food industry. However, the A. niger strain has defects such as easy degradation and instability in the expression of sn-1,3 lipase. To obtain a stable expression of this lipase and its subsequent enzymatic properties, the gene encoding EXANL1 was cloned and expressed in Escherichia coli BL21 (DE3) cells using pET-28a as the expression vector. The temperature-induced conditions were optimized, and we successfully achieved its active expression in E. coli. These conditions significantly influenced the active expression of EXANL1 (P < 0.05), and the highest enzyme activity of the supernatant of lysis cells expressed at 20 °C was at 7.02 ± 0.05 U/mL. The expressed recombinant EXANL1 was purified using Ni-NTA, showing an estimated relative molecular mass of 35 kDa. The recombinant EXANL1 exhibited maximum activity at 35 °C and pH 4.0, with a wide acid pH range. Thin-layer chromatography analysis showed that the enzyme displayed sn-1,3 positional selectivity toward triolein. The recombinant EXANL1 could maintain its relative activities (> 80%) after 24 h of incubation at pH 3-10, suggesting its suitability for a wide range of industrial applications. After comparing these properties with those of the other A. niger lipases, we found that some key amino acids may play a decisive role in enzymology. This work laid a foundation for the stable expression of the EXANL1 gene and its potential industrial application.

Abstract
Deacidification of high-acid soy sauce residue (SSR) oil is crucial to utilization of SSR oil. Aspergillus niger lipase (ANL) has been widely applied for such purpose while its immobilization still has large room for improvement. ANL was immobilized onto six different macroporous acrylic resins, accounting the effect of the different textural properties of resins on stability and their potential for application in enzymatic deacidification. The resin MARE with lower porosity, higher bulk density, and medium hydrophobicity, was chosen as the best carrier for the best thermostability and reusability. ANL-MARE is a promising catalyst than Novozym 40086, which not only exhibited higher deacidification activity and good thermostability, but also was continuously reused for 15 cycles and efficiently catalyzed from high-acid SSR oil into diacylglycerol-enriched oil. Therefore, immobilized ANL was a novel, low-cost and recyclable biocatalyst that could be used as a good alternative to higher-cost commercial lipases in industrial applications.

Abstract
Innovative materials were made via the combination of chitin and lignin, and the immobilization of lipase from Aspergillus niger. Analysis by techniques including FTIR, XPS and 13C CP MAS NMR confirmed the effective immobilization of the enzyme on the surface of the composite support. The electrokinetic properties of the resulting systems were also determined. Results obtained from elemental analysis and by the Bradford method enabled the determination of optimum parameters for the immobilization process. Based on the hydrolysis reaction of para-nitrophenyl palmitate, a determination was made of the catalytic activity, thermal and pH stability, and reusability. The systems with immobilized enzymes were found to have a hydrolytic activity of 5.72 mU, and increased thermal and pH stability compared with the native lipase. The products were also shown to retain approximately 80% of their initial catalytic activity, even after 20 reaction cycles. The immobilization process, using a cheap, non-toxic matrix of natural origin, leads to systems with potential applications in wastewater remediation processes and in biosensors.

Abstract
This study introduces a novel bacterium-Pseudomonas sp. strain BUP6-isolated from the rumen of the Malabari goat with efficiency for producing lipase. It showed significant production of lipase when grown in a newly designed basal medium, supplemented with vegetable oil. Suitability of five vegetable oils such as groundnut oil, coconut oil, olive oil, sunflower oil, and palm oil as inducer for the production of lipase was examined, and groundnut oil supported the highest production of lipase (96.15 U/mL). Various physical parameters required for the maximum production of lipase were statistically optimized. Plackett-Burmann design was employed to study the interactive effects of physical parameters and found that temperature, agitation, and pH effected the production of lipase significantly. The optimum conditions for lipase production (37 °C, 200 rpm, and pH 6.9) were detected by Box-Behnken design and response surface methodology, which resulted in the 0.3-fold increase (i.e., 126 U/mL) of the lipase activity over the unoptimized condition. The apparent molecular mass of partially purified lipase was 35 kDa, as judged by SDS-PAGE; the activity of lipase was also confirmed by native PAGE. Thus, this study focuses on the need for the exploitation of rumen microbes for the production of industrially significant and human-friendly biomolecules to meet the future needs.

Abstract
Lipases are water-soluble enzymes that act on insoluble substrates and catalyze the hydrolysis of long-chain triglycerides. Lipases play a vital role in the food, detergent, chemical, and pharmaceutical industries. In the past, fungal lipases gained significant attention in the industries due to their substrate specificity and stability under varied chemical and physical conditions. Fungal enzymes are extracellular in nature, and they can be extracted easily, which significantly reduces the cost and makes this source preferable over bacteria. Soil contaminated with spillage from the products of oil and dairy harbors fungal species, which have the potential to secrete lipases to degrade fats and oils. Herein, the strategies involved in the characterization of fungal lipases, capable of degrading fatty substances, are narrated with a focus on further applications.

Abstract
Lipase A from Candida antarctica (CAL A) was purified to apparent homogeneity in a single step using hydroxyapatite (HAP) chromatography. CAL A bound to HAP was eluted with 10mM Na-phosphate buffer, pH 7.0 containing 0.5% Triton X-100. The protocol resulted in a 3.74-fold purification with 94.7% final recovery and 400.83 U/mg specific activity. Silver staining after SDS-PAGE revealed the presence a single band of 45 kDa. The enzyme exhibited a temperature optimum of 60°C, was unaffected by monovalent metal ions, but was destabilized by divalent metal ions (Zn(2+), Ca(2+), Mg(2+), Cu(2+), Mn(2+)) and stimulated by 50mM Fe(2+). Detergents at 0.1% concentrations did not affect lipase activity. Except for Triton X-100, detergent concentrations of 1% had a destabilizing effect.

Abstract
Aspergillus niger lipase (ANL), a widely used hydrolase, was displayed for the first time on the surface of Saccharomyces cerevisiae using a-agglutinin as an anchor protein. Localization of ANL on the cell surface was confirmed by immunofluorescence microscopy. The displayed ANL was confirmed to be active toward tributyrin and p-nitrophenyl caprylate (pNPC). The hydrolytic activity toward pNPC reached 43.8 U/g of dry cell weight after induction by galactose for 72 h. The ANL-displaying cells were characterized for their use as whole-cell biocatalysts. The optimum temperature was 45 °C, and the pH was 7.0. The cells had good thermostability, retaining almost 80% of the full activity after incubation at 60 °C for 1 h, and >80% of the full activity at 50 °C for 6 h. The displayed lipase showed a preference for medium-chain fatty acid p-nitrophenyl esters. Therefore, the produced whole-cell catalyst is likely to have a wide range of applications.

Abstract
We have cloned a novel lipase gene, lip2, from Aspergillus niger and expressed it in Escherichia coli. Upon purification of the recombinant Lip2 protein, its properties were characterized. In comparison with a previously identified lipase Lip1, both enzymes are acid lipases (optimal pH <6.5), Ca(2+)-dependent and PMSF-sensitive, but have different molecular weights (35 and 43 kDa), optimal substrate spectra (C10 and C8), optimal reaction temperatures (45 and 50 degrees C) and thermal stability. Circular dichroism spectroscopy revealed that Lip2 contains a typical Ca(2+)-active site. This first report on the cloning of the Lip2 gene and its enzymatic characteristics may greatly facilitate its potential industrial application.

Abstract
Este trabalho teve por objetivo estabelecer um processo para obter e caracterizar os produtos da cristalização das frações do óleo de pescado hidrolisado com lipase pancreática. A hidrólise enzimática foi realizada em 60 minutos com uma concentração de substrato de 1262 mmols, 38 °C, pH 8 e com uma concentração de extrato enzimático de 7,647 mg.mL-1. Os produtos da hidrólise foram separados por cromatografia em coluna e caracterizados por cromatografia em camada delgada e cromatografia em fase gasosa. A temperatura de cristalização foi controlada entre 5 °C e -18 °C. A fração TAG foi melhor cristalizada a 0 °C enquanto que as frações DAG + AGL e MAG foram cristalizadas a 5 °C. Foi observado que o ácido docosahexaenoico (DHA) concentra-se na fase líquida da fração DAG + AGL representando 97,17% em relação ao óleo de pescado. O ácido palmítico foi cristalizado na fração DAG, perfazendo aproximadamente 50% do total de ácidos graxos. Foi observado que os ácidos graxos insaturados de cadeia longa, principalmente o EPA, concentram-se na fase sólida da fração TAG, esses resultados sugerem que o processo combinado de hidrólise enzimática seguido de cristalização possibilita a obtenção destes ácidos graxos do óleo de pescado.

Abstract
Two recombinant strains of Aspergillus niger (NW 297-14 and NW297-24) producing a heterologous lipase from Thermomyces lanuginosus were constructed. The heterologous lipase was expressed using the TAKA amylase promoter from Aspergillus oryzae. The production kinetics of the two strains on different carbon sources in batch and carbon-limited chemostat cultivations were evaluated. In batch cultivations, the highest total product yield coefficient (Y(xp total)), given as the sum of extracellular and intracellular yields, was obtained during growth on glucose for the transformant strain NW297-24 (5.7+/-0.65 KU/g DW), whereas the highest total product yield coefficient was obtained during growth on maltose for the transformant strain NW297-14 (6.3+/-0.02 KU/g DW). Both transformants were evaluated in glucose-limited chemostat cultures. Strain NW297-14 was found to be the best producer and was thus employed for further analysis of the influence of carbon source in chemostat cultures. Here, the highest total specific lipase productivity (r(p total), the sum of extracellular and intracellular lipase productivity) was found to be 1.60+/-0.81 KU/g DW/h in maltose-limited chemostats at a dilution rate of 0.08 h(-1), compared with a total specific lipase productivity of 1.10+/-0.41 KU/g DW/h in glucose-limited chemostats. At the highest specific productivity obtained in this study, the heterologous enzyme accounted for about 1% of all cellular protein being produced by the cells, which shows that it is possible to obtain high productivities of heterologous fungal enzymes in A. niger. However, SDS-PAGE analysis showed that most of the produced lipase was bound to the cell wall.
