Functional and molecular characterization of a cold-active lipase from Psychrobacter celer PU3 with potential a*ntibiofilm property. Int J Biol Macromol 2022; 211:741-753. [PMID: 35504418 DOI: 10.1016/j.ijbiomac.2022.04.174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 04/07/2022] [Accepted: 04/24/2022] [Indexed: 11/05/2022]
Abstract
The lipase gene from Psychrobacter celer PU3 was cloned into pET-28a(+) expression vector and overexpressed in E. coli BL21 (DE3) pLysS cells. The purified Psychrobacter celer lipase (PCL) was characterized as an alkaline active enzyme and has a molecular mass of around 30 kDa. The PCL was active even at a low temperature and the optimum range was observed between 10 and 40 °C temperatures. MALDI-TOF and phylogenetic analysis ensued that Psychrobacter celer PU3 lipase (PCL) was closely related to P. aureginosa lipase (PAL). MD simulation results suggests that temperature change did not affect overall structure of PCL, but it may alter temperature- dependent PCL structural changes. R1 (129-135 AA) and R2 (187-191 AA) regions could be important for temperature-dependent PCL function as they fluctuate much at 35 °C temperature. PMSF completely inhibited PCL lipase activity and it demonstrates the presence of serine residues in the active site of PCL. PCL is moderately halophilic and most of the tested organic solvents found to be inhibiting the lipase activity except the solvents ethanol and methanol. PCL activity was increased with surfactants (SDS and CTAB) and bleaching agents (hydrogen peroxide). The effect of different metal ions on PCL resulted that only mercuric chloride was found as the enhancer of the lipase activity. Antibiofilm property of PCL was evaluated against pathogenic Vibrio parahaemolyticus isolated from the diseased shrimp and MIC value was 500 U. PCL significantly altered the morphology and biofilm density of V. parahaemolyticus and the same was observed through scanning electron microscope (SEM) and confocal laser scanning microscope (CLSM) imaging. RT-PCR analysis revealed that the mRNA expression level of biofilm, colony morphology and major toxin-related (aphA, luxS, opaR, tolC, toxR) genes of V. parahaemolyticus were significantly downregulated with PCL treatment.

Characterization of Some Salt-Tolerant Bacterial Hydrolases with Potential Utility in Cultural Heritage Bio-Cleaning. Microorganisms 2022; 10:microorganisms10030644. [PMID: 35336219 PMCID: PMC8949325 DOI: 10.3390/microorganisms10030644] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/11/2022] [Accepted: 03/15/2022] [Indexed: 02/04/2023] Open
Abstract
Salt-tolerant enzymes produced by halophilic and halotolerant microorganisms have been proposed to be used in various applications that involve high saline conditions. Considering their biotechnological significance and the current need for more efficient producers of such catalysts, the present study aimed to evaluate the extracellular proteolytic, esterolytic, cellulolytic and xylanolytic activities of some halotolerant strains, and to characterize their functional parameters. A total of 21 bacterial and fungal strains belonging to the genera Bacillus, Virgibacillus, Salinivibrio, Salinicoccus, Psychrobacter, Nocardiopsis, Penicillium, Aspergillus, and Emericellopsis were assayed by quantitative methods. Among them, the members of the Bacillus genus exhibited the highest catalytic activities. The exoenzymes produced by three selected Bacillus strains were active over wide ranges of salinity, temperature and pH. Proteases were active at 20–80 °C, pH 6–10, and 0–1 M NaCl, while esterases showed good catalytic activities at 20–80 °C, pH 7.5–10, and 0–4 M NaCl. Cellulases and xylanases were active at 20–80 °C, pH 5–10, and 0–5 M NaCl. Due to such properties, these hydrolases could be used in a newly proposed application, namely to clean aged consolidants and organic deposits accumulated over time from the surfaces of salt-loaded wall paintings.

Abstract
Microbial lipases are commercially significant due to their versatile catalytic function of hydrolysis triacylglycerol. Among these, lipases from extremophiles are optimal for industrial application. Halophilic microorganisms living in a high salinity environment, such as the ocean, salt lakes, salt wells, and so on, produce halophilic lipases. In recent decades, many remarkable achievements have been made related to the properties and application of halophilic lipases. This review offers information collected over the last decades on halophilic lipase sources as well as advances in production, factors influencing activity, stability under various conditions, structural characteristics, progress in industrial applications such as food flavor modification, biodiesel production, and waste treatment, to provide theoretical and methodological references for the research in this direction.

Abstract
Lipases are hydrolytic enzymes owing much importance in industrial applications. These enzyme-based detergents are ecofriendly and produce a wastewater with low level of COD (chemical oxygen demand). In the present work, a novel halophilous, thermoalkaline, and detergent-tolerant lipase produced by a newly isolated Aeribacillus pallidus strain VP3 was studied. Considerable interest has been given to this lipase by the improvement of its catalytic activity through the optimization of the pH, the (C/N) ratio, and the inoculum size, using the response surface methodology based on the Box-Behnken design of experiments. A total of 16 experiments were conducted, and the optimized pH, (C/N) ratio, and inoculum size were 10, 1, and 0.3, respectively. The results of the analysis of variance (ANOVA) test indicated that the established model was significant (p value < 0.05). The optimization of the production conditions leads to 2.83-fold of increase in the catalytic activity calculated as the ratio of the activity obtained after optimization (68 U) and the initial activity before optimization (24 U). All in all, the lipase of Aeribacillus pallidus could be considered as a potential candidate to be incorporated in detergent formulations since it shows a good stability towards detergents and wash performance.

Abstract
Global warming and the limitations of using fossil fuels are a main concern of all societies, and thus, the development of alternative fuel sources is crucial to improving the current global energy situation. Biofuels are known as the best alternatives of unrenewable fuels and justify increasing extensive research to develop new and less expensive methods for their production. The most frequent biofuels are bioethanol, biobutanol, biodiesel, and biogas. The production of these biofuels is the result of microbial activity on organic substrates like sugars, starch, oil crops, non-food biomasses, and agricultural and animal wastes. Several industrial production processes are carried out in the presence of high concentrations of NaCl and therefore, researchers have focused on halophiles for biofuel production. In this review, we focus on the role of halophilic microorganisms and their current utilization in the production of all types of biofuels. Also, the outstanding potential of them and their hydrolytic enzymes in the hydrolysis of different kind of biomasses and the production of biofuels are discussed.

Abstract
The aim of this study was to isolate a novel esterase from a hypersaline lake by sequence-based metagenomics. The metagenomic DNA was isolated from the enriched hypersaline lake sediment. Degenerate primers targeting the conserved regions of lipolytic enzymes of halophilic microorganisms were used for polymerase chain reaction (PCR) and a whole gene was identified by genome walking. The gene was composed of 783 bp, which corresponds to 260 amino acids with a molecular weight of 28.2 kDa. The deduced amino acid sequence best matched with the esterase from Halomonas gudaonensis with an identity of 91%. Recombinantly expressed enzyme exhibited maximum activity towards pNP-hexanoate with a kcat value of 12.30 s-1. The optimum pH and temperature of the enzyme were found as 9 and 30 °C, respectively. The effects of NaCl, solvents, metal ions, detergents and enzyme inhibitors were also studied. In conclusion, a novel enzyme, named as hypersaline lake "Acıgöl" esterase (hAGEst), was identified by sequence-based metagenomics. The high expression level, the ability to maintain activity at cold temperatures and tolerance to DMSO and metal ions are the most outstanding properties of the hAGEst.

Abstract
An approach was made to enhance the halophilic lipase secretion by a newly isolated moderate halophilic Marinobacter litoralis SW-45, through the statistical optimization of Plackett-Burman (PB) experimental design and the Face Centered Central Composite Design (FCCCD). Initially, PB statistical design was used to screen the medium components and process parameters, while the One-factor-at-a-time technique was availed to find the optimum level of significant parameters. It was found that MgSO4 · 7H2 O, NaCl, agitation speed, FeSO4 · 7H2 O, yeast extract and KCl positively influence the halophilic lipase production, whereas temperature, carbon source (maltose), inducer (olive oil), inoculum size, and casein-peptone had a negative effect on enzyme production. The optimum level of halophilic lipase production was obtained at 3.0 g L-1 maltose, 1% (v/v) olive oil, 30 °C growth temperature and 4% inoculum volume (v/v). Further optimization by FCCCD was revealed 1.7 folds improvement in the halophilic lipase production from 0.603 U ml-1 to 1.0307 U ml-1 . Functional and biochemical characterizations displayed that the lipase was significantly active and stable in the pH ranges of 7.0-9.5, temperature (30-50 °C), and NaCl concentration (0-21%). The lipase was maximally active at pH 8.0, 12% (w/v) NaCl, and 50 °C temperature. Besides, M. litoralis SW-45 lipase was found to possess the promising industrial potential to be utilized as a biocatalyst for the esterification.
