Abstract
The filamentous Thermoascus aurantiacus fungus characterized by its thermophilic nature, is recognized as an exceptional producer of various enzymes with biotechnological applications. This study aimed to explore biotechnological applications using polygalacturonase (PG) derived from the Thermoascus aurantiacus PI3S3 strain. PG production was achieved through submerged fermentation and subsequent purification via ion-exchange chromatography and gel filtration methods. The crude extract exhibited a diverse spectrum of enzymatic activities including amylase, cellulase, invertase, pectinase, and xylanase. Notably, it demonstrated the ability to hydrolyze sugarcane bagasse biomass, corn residue, and animal feed. The purified PG had a molecular mass of 36 kDa, with optimal activity observed at pH 4.5 and 70 °C. The activation energy (Ea) was calculated as 0.513 kJ mol-1, highlighting activation in the presence of Ca2+. Additionally, it displayed apparent Km, Vmax, and Kcat values of at 0.19 mg mL-1, 273.10 U mL-1, and 168.52 s-1, respectively, for hydrolyzing polygalacturonic acid. This multifunctional PG exhibited activities such as denim biopolishing, apple juice clarification, and demonstrated both endo- and exo-polygalacturonase activities. Furthermore, it displayed versatility by hydrolyzing polygalacturonic acid, carboxymethylcellulose, and xylan. The T. aurantiacus PI3S3 multifunctional polygalacturonase showed heightened activity under acidic pH, elevated temperatures, and in the presence of calcium. Its multifunctional nature distinguished it from other PGs, significantly expanding its potential for diverse biotechnological applications.

Abstract
Synthetic dye bioremediation is a topic of great importance since these pollutants possess toxic effects, and huge quantities of them are being discharged into water bodies. Ligninolytic enzyme treatment stands out for being a cost-effective methodology, capable of obtaining high decolorization levels. In this work, a laccase enzyme treatment was evaluated to effectively perform a cycle of dye bioremediation. Furthermore, a dye decolorization improvement was also assessed through laccase immobilization. Particularly, a Trametes pubescens enzyme extract was concentrated, immobilized onto calcium alginate beads, and characterized to assess its dye decolorization potential. Ammonium sulfate precipitation and vacuum evaporation were evaluated to concentrate the crude extract and to decolorize allura red AC. Both treatments reached a high enzyme yield recovery (>90%), but only the vacuum-evaporated extract achieved a high allura red AC decolorization level after 16 h of contact time. This suggested that essential compounds for allura red AC decolorization were present in the crude extract, implying that neither a complete laccase purification process nor an addition of synthetic mediators are necessary. Under optimized immobilization conditions, 94.6% immobilization efficiency and 49.8% activity recovery were obtained with 0:1 alginate:enzyme (v/v), 100 mM CaCl2, and 5.0% w/v sodium alginate. Furthermore, by immobilizing the laccase concentrated extract, both the pH and temperature stabilities were improved. The decolorization of allura red AC by free and immobilized laccase was 68.4% and 4.6%, respectively, showing that although the enzyme stability was improved, dye decolorization was negatively affected. Thus, an efficient allura red AC decolorization was obtained with concentrated-free laccase by a feasible and low-cost methodology.

Abstract
Pectinases and other carbohydrate-active enzymes are important for the food industry, mainly for juice processing. In addition, the use of peels to produce enzymes can aggregate value to these agro-industrial residues and at the end of the process enhance qualitatively and quantitatively the juice production. In this work, three different extracts produced by Penicillium oxalicum LS09 using agro-industrial residues were optimized and analyzed by mass spectrometry. It was observed an increased production of pectinases in the medium containing orange peel and optimized for production of pectin lyase and pectinesterase (PE). Interestingly, not only pectinases, but also different plant cell wall degrading enzymes (i.e. glucanases, xylanases, arabinases), with a higher ratio (42/73) was identified in the medium optimized for PE. The crude extracts produced by P. oxalicum also reveal the potential for application in the fruit juice industry, showing an increased yield and qualitative characteristics of extracted juices. The presence of other cell wall-degrading enzymes identified by proteomics, reinforce the combination for obtaining clarified and depectinized juice in a single step.

Abstract
Polygalacturonases (PG) represent an important member of pectinases group of enzymes with immense industrial applications. A fungal strain Aspergillus niger MTCC478 was used for the production of polygalacturonase both under submerged and solid-state fermentation condition. Further its production was optimized under solid-state fermentation condition with media comprising of wheat bran and tea extract. Purification of an exo-PG was achieved by acetone precipitation (60-90%) and CM-cellulose column chromatography revealing 15.28-fold purification with a specific activity of 33.47 U/mg protein and 1.2% yield. A relative molecular mass of purified PG was approximately 124.0 kDa. The pH and temperature optimum was found to be 4 and 50 °C, respectively. The k cat and K m value for degradation of PGA by the purified enzyme was found to be 194 s-1 and 2.3 mg/mL, respectively. Cu2+ was found to enhance the PG activity while Ag+ completely inhibited the enzyme activity. The application of the purified PG in orange juice clarification was elucidated.

Abstract
An endo-polygalacturonase secreted by <i>Aspergillus sojae </i>was characterized after being purified to homogeneity from submerged cultures with orange peel as the sole carbon source by gel filtration and ion-exchange chromatographies. According to SDS-PAGE and analytical isoelectric focusing analyses, the enzyme presents a molecular weight of 47 kDa and pI value of 4.2. This enzyme exhibits considerable stability under highly acidic to neutral conditions (pH 1.5-6.5) and presents a half-life of 2 h at 50°C. Besides its activity towards pectin and polygalacturonic acid, the enzyme displays pectin-releasing activity, acting best in a pH range of 3.3-5.0. Thin-layer chromatographic analysis revealed that tri-galacturonate is the main enzymatic end product of polygalacturonic acid hydrolysis, indicating that it is an endo-polygalacturonase. The enzyme exhibits Michaelis-Menten kinetics, with K<sub>M</sub> and V<sub>MAX</sub> values of 0.134 mg/mL and 9.6 µmol/mg/min, respectively, and remained stable and active in the presence of SO<sub>2</sub>, ethanol, and various cations assayed except Hg<sup>2+</sup>.

Abstract
Polygalacturonases represents an important member of pectinases group of enzymes with diverse industrial applications and is widely distributed among fungi, bacteria, yeasts, plants and some plant parasitic nematodes. An endo-polygalacturonase from a new fungal source Aspergillus fumigatus MTCC 2584 was produced under solid-state fermentation conditions and was purified simply by acetone precipitation and gel-filtration chromatography technique. The approximate molecular weight of the purified PG was found to be 43.0 kDa as revealed by SDS-PAGE. The pH optimum of the purified enzyme was found to be 10.0 and was stable in the pH range of 7-10. The optimum temperature of purified PG was found to be 30 °C. The Km and Kcat of the purified enzyme were 2.4 mg/ml and 44 s-1, respectively, and the metal ions Cu2+ and K+ were found to enhance the enzyme activity while Ag+, Ca2+ and Hg2+ were inhibitory in nature. Based on its alkaline nature, the potential of purified PG in retting of natural fiber Crotalaria juncea was elucidated in the absence of EDTA. This is probably the first report of alkaline PG from Aspergillus fumigatus.
