The use of waste as raw material is important for government economy and natural balance. purpose this work was to study the production CMCase xylanase by a Brazilian strain Thermoascus aurantiacus in solid state fermentation (SSF) using different agricultural residues (wheat bran, sugarcane bagasse, orange corncob, green grass, dried sawdust corn straw) substrates without enrichment medium characterize crude enzymes.The extracellular cellulolytic hemicellulolytic enzymes showed that T....
The aim of this study was the detailed characterization phenolic composition and determination antioxidant activity Bordô grape (Vitis labrusca) cultivated in South Brazil. edible parts grapes (flesh skin) contained 1130 mg/kg total compounds (as gallic acid), mainly located skins. Anthocyanin content skins high, largely as 3,5-diglucosides (1359 mg/kg, malvidin 3,5-diglucoside). Total flavonols accounted for 154 μmol/kg, with myricetin 3-glucoside principal flavonol both parts. Very low...
Aims To obtain new cellulases and xylanases from thermophilic fungi; evaluate their potential for sugarcane bagasse saccharification. Methods Results Thirty-two heat-tolerant fungi were isolated the environment, identified (morphological/molecular tools) production of enzymes was evaluated by solid state fermentation using lignocellulosic materials as substrates. Myceliophthora thermophila JCP 1-4 best producer endoglucanase (357·51 U g−1), β-glucosidase (45·42 xylanase (931·11 g−1)...
One hundred sixty eight bacterial strains, isolated from soil and samples of vegetable in decomposition, were screened for the use citrus pectin as sole carbon source. 102 positive pectinase depolymerization assay plates evidenced by clear hydrolization halos. Among them, 30% presented considerable pectinolytic activity. The cultivation these strains submerged semi-solid fermentation polygalacturonase production indicated that five Bacillus sp produced high quantities enzyme....
Pectin lyase and polygalacturonase production by newly isolated Penicillium viridicatum strain Rfc3 was carried out means of solid state fermentation using orange bagasse, corn tegument, wheat bran mango banana peels as carbon sources. The maximal activity value (Pg) (30U.g-1) obtained source while pectin (Pl) (2000 U.g-1) in medium composed bagasse. Mixtures or with sugar cane bagasse resulted increased Pg Pl compared to fermentations which this residue not used. mixture (50%) the 55 U.g-1...
Pectin lyase and polygalacturonase production by newly isolated fungal strains was carried out in solid-state fermentation. Moniliella SB9 Penicillium sp EGC5 produced polygalcturonase (PG) pectin (PL) on mixture of orange bagasse, sugar cane bagasse wheat bran as substrate. PG PL presented optimum activity at pH 4.5 10.0 55 45°C, respectively, while these enzymes from 4.5-5.0 9.0 40°C, respectively.
Twenty-seven thermophilic and thermotolerant fungal strains were isolated from soil, decaying organic matter sugarcane piles based on their ability to grow at 45ºC medium containing corn straw cardboard as carbon sources. These fungi identified in the genera Aspergillus, Thermomyces, Myceliophthora, Thermomucor Candida. The majority of produced xylanase cellulases under solid state fermentation (SSF). highest cellulase productions obtained by cultivation Aspergillus fumigatus M.7.1...
Microbial rennet-like milk-clotting enzymes are aspartic proteinases that catalyze milk coagulation, substituting calf rennet. Crude enzymatic extract produced by the thermophilic fungus, Thermomucor indicae-seudaticae N31, on solid state fermentation (SSF) using wheat bran, exhibited high activity and low proteolytic after 24 h of fermentation. Highest (MCA) was at pH 5.7, 70 °C in 0.04 M CaCl2; it stable range 3.5–4.5 for up to 45 1 h. MCA highly inhibited pepstatin A. Hydrolytic profile...
Sugarcane bagasse (SCB) was treated in three stages using ozone oxidation (O), washing an alkaline medium (B) and ultrasonic irradiation (U). The impact of each pretreatment stage on the physical structure SCB evaluated by its chemical composition, infrared technique (FTIR-ATR), thermogravimetric analysis (TGA/DTG). sequence O, B, U provided a significant reduction lignin hemicellulose, which confirmed changes absorption bands corresponding to these compounds, when observed infrared....
