AB  - Pectinases are a type of enzymes frequently used in the food industry to clarify, liquefy, and stabilize fruit juices. The main challenge in fruit juice production is the cloudiness of the juice, which is largely caused by the presence of pectic polysaccharides. Endo-pectinases are enzymes that hydrolyze the glycosidic bonds in pectic polymers. Commercial pectinolytic enzymes are typically produced by fungi, with Aspergillus spp. being the most commonly used.
The aim of this research was the production and characterization of a novel endo-pectinase from the Aspergillus tubingensis strain for use in liquefying and clarifying different types of fruit juice. To accomplish this, solid-state fermentation was conducted on agricultural waste, such as sugar beet pulp and wheat bran, to produce pectinolytic enzymes. The resulting crude extract was concentrated via ultrafiltration and used to isolate the endo-pectinase via ammonium sulfate and ethanol precipitation methods. Ion-exchange chromatography technique on DEAE Sephadex A-25 matrix was used for further purification of the endo-pectinase.
The purified enzyme was characterized by the determination of total pectinolytic activity, specific pectinolytic activity, and SDS-PAA gel electrophoresis. The activity of the endo-pectinase was confirmed by a diffusion test and zymography with Ruthenium Red visualization. The resulting enzyme was used to liquefy apricot, banana, apple, quince, strawberry, and orange pulp, with juice yields ranging from 71% to 83%, depending on the fruit used. The juices treated with endo-pectinase showed much higher clarification compared to untreated juices. Additionally, the treated juices demonstrated more pronounced antioxidant properties, as determined through the DPPH assay.

AB  - The main goal of this study was to examine the efficiency of a newly isolated fungus from quince, Aspergillus tubingensis FAT43, to produce the pectinolytic complex using agricultural and industrial waste as the substrate for solid state fermentation. Sugar beet pulp was the most effective substrate inducer of pectinolytic complex synthesis out of all the waste residues examined. For endo-pectinolytic and total pectinolytic activity, respectively, statistical optimization using Placked-Burman Design and Optimal (Custom) Design increased production by 2.22 and 2.15-fold, respectively. Liquification, clarification, and an increase in the amount of reducing sugar in fruit juices (apple, banana, apricot, orange, and quince) processed with pectinolytic complex were identified. Enzymatic pre-treatment considerably increases yield (14%–22%) and clarification (90%). After enzymatic treatment, the best liquefaction was observed in orange juice, whereas the best clarification was obtained in apricot juice. Additionally, the pectinolytic treatment of apricot juice resulted in the highest increase in reducing sugar concentration (11%) compared to all other enzymatically treated juices. Optimizing the production of a highly active pectinolytic complex and its efficient utilization in the processing of fruit juices, including the generation of an increasing amount of waste, are the significant outcomes of this research.

AB  - Pectinases are widely used in the fruit juice industry for clarification, liquefaction and stabilization of juices. Primarily, these enzymes are responsible for the breakdown of long and complex molecules in the fruit pulp (pectin). Unlike the combination of polygalacturonase (PG) and pectin esterase (PE) commonly found in commercial products, pectin lyase (PNL) is the only known pectinase capable of breaking down highly esterified pectins (such those found in fruits) into short molecules via a β-elimination mechanism without producing methanol. Methanol is toxic and can be harmful to health. Commercial preparations with PNL as the major component are preferable in juices and wine processing because it avoids the production of methanol, precipitation of pectin partially de-esterified with endogenous calcium, and damage of the volatile ester content responsible for the specific aroma of various fruits. This study reports the first cloning and characterization of a PNL gene, ppr, from Bacillus velezensis, and the deduced amino acid sequence is compared with those of other lyases. In this work, the gene encoding the pectin lyase (PNL; EC 4.2.2.10) from Bacillus velezensis was successfully expressed under optimized conditions for high soluble protein expressions as soluble PNL-6His in E. coli M15[pREP4]. After expression, purification of 6xHis-labeled PNL was performed according to QIAGEN instructions. IMAC fractions were analyzed using SDS-PAGE. After purification, 3-fold purification was observed with a yield of 82%. In this study, we report for the first time a method to express PNL in E. coli and purify it as a pure native enzyme. The cloned PLN was used to clarify and liquefy apple and orange juices and to improve the flavor of these juices. In this way, pulp waste after juice extraction is reduced. Methanol content was determined by gas-liquid chromatography and was not detectable in the clarified juices.

AB  - Organophosphate-based pesticides have remarkably contributed to the agriculture industry, but their toxicity has a large negative impact on the environment as well as on the health of humans and other living organisms. Most of the methods developed to remedy the organophosphate pesticide toxicity are very time-consuming and are based on their adsorption onto different materials and/or their degradation to nontoxic species. In this study, detoxification of three structurally different organophosphate pesticides was investigated using an NU-1000 metal-organic framework. We showed that NU-1000 is an excellent agent for fast (average time ≤ 3 min) and effective removal of organophosphate pesticides with an aromatic heterocyclic moiety. In particular, superior detoxification of chlorpyrifos solution after NU-1000 treatment was achieved after only 1 min. The combination of experimental and computational methods revealed that the synergic effects of sorption and hydrolysis are responsible for the superior removal of CHP by NU-1000. The sorption process occurs on the Zr node (chemisorption) and pyrene linkers (physisorption) following pseudo-first-order kinetics during the first minute, and a pseudo-second-order model fits the entire time range. The multilayer adsorption of chlorpyrifos or its hydrolyzed product, 3,5,6-trichloro-2-pyridinol, takes place on a pyrene linker, whereas the aliphatic part of the molecule remains chemisorbed on the Zr node. Such unique synergy between induced sorption and hydrolysis of chlorpyrifos by NU-1000 results in its fast and effective removal with rapid detoxification in non-buffered solutions.

AB  - Investigation was carried out on austenitic material samples – stainless steel and iron base superalloy that are widely used at elevated temperatures and pressures. The samples were exposed to Nd:YAG pulsed laser, with wavelength  of 1064 nm and pulse duration of 170 ps. Different pulse energy and number of pulses were applied. Spots obtained by laser interaction were observed by optical and scanning electron microscope and analyzed by energo-dispersive spectroscopy. Vickers microhardness tests were performed. In this paper, the microstructural changes, arisen by different pulse energy and number of pulses, were discussed with the aim to determine optimal laser parameters in surface treatment process.
