37. Molecular characterization of a Xylanase-producing fungus isolated from fouled soil
Xylanase (EC 3. 2. 1. 8), hydrolyzes xylo-oligosaccharides into D-xylose and required for complete hydrolysis of native cellulose and biomass conversion. It has broad range of applications in the pulp and paper, pharmaceutical and Agri-food industries. Fifty fungal species were isolated from the fouled soil around an oil refinery and screened for the product

38. Optimization of fibrinolytic protease production from Bacillus subtilis I-2 using agro-residues
The aim of this work was to study the production of fibrinolytic protease by Bacillus subtilis I-2 on agricultural residues. Molasses substantially enhanced (63%) protease production (652.32 U/mL) than control (398.64 U/mL). Soybean meal supported maximum protease production (797.28 U/mL), followed by malt extract (770.1 U/mL), cotton cake (761.04 U/mL), gel

39. Soybean β-Glucosidase immobilisated on chitosan beads and its application in soy drink increase the aglycones
The objective of this study was to investigate the immobilisation efficiency of soybean β-glucosidase (181.6 U/mL; 23.8 mg protein/mL) on activated chitosan beads. Central Composite Rotational Design (CCDR) 23 was used and the application of immobilised enzyme in commercial soy drink was evaluated. The activation of chitosan beads was achieved with establis

40. É necessário aumentar a dose de levotiroxina em pacientes com hipotireoidismo que usam omeprazol?
Objetivo Acredita-se que o pH gástrico possa interferir na absorção de levotiroxina. O omeprazol, ao inibir a secreção de ácido gástrico, poderia interferir no controle do hipotireoidismo em pacientes em uso de levotiroxina de forma dose-dependente. O presente estudo tem como objetivo investigar essa hipótese. Sujeitos e métodos Vinte e um paci

41. Concomitant production of detergent compatible enzymes by Bacillus flexus XJU-1
A soil screened Bacillus flexus XJU-1 was induced to simultaneously produce alkaline amylase, alkaline lipase and alkaline protease at their optimum levels on a common medium under submerged fermentation. The basal cultivation medium consisted of 0.5% casein, 0.5% starch and 0.5% cottonseedoil as an inducer forprotease, amylase, and lipase, respectively. The

42. Peptidase with Keratinolytic Activity Secreted by Aspergillus terreus During Solid-State Fermentation
The aim of this study was to evaluate peptidase production by Aspergillus terreus in solid-state bioprocess and evaluate its parameters. The best conditions were 5.0 g of wheat bran as substrate, incubation temperature 30°C, inoculum 2.0x105spores/g and 75% saline volume, with production reaching 677 U/mL (5400 U/g culture medium) after 72 h of fermentation

43. Diagnóstico preventivo de laminite em bovinos de leite
Esta pesquisa teve como objetivo desenvolver um sistema especialista baseado em inferência Fuzzy para prevenir a laminite em vacas leiteiras. O comprimento do casco, parâmetros nutricionais e propriedades do piso (rugosidade) foram utilizados para construir o sistema de inferência Fuzzy. A arquitetura do sistema especialista foi definida utilizando a Unif

44. Optimization of biodegradable plastic production on sugar cane molasses in Enterobacter sp. SEL2
Contaminated environments have a large number of bacteria which can accumulate PHA as their energy reserves. Out of 54 isolated bacterial strains from three groups of contaminated sites 48 were found PHA positive. The sites were grouped on the basis of the type of carbon sources i.e. sugars, fatty acids and much diverse type. Strains MFD5, MFD11, UML3, USL2,

45. Aflatoxin detoxification by manganese peroxidase purified from Pleurotus ostreatus
Manganese peroxidase (MnP) was produced from white rot edible mushroom Pleurotus ostreatus on the culture filtrate. The enzyme was purified to homogeneity using (NH4)2SO4 precipitation, DEAE-Sepharose and Sephadex G-100 column chromatography. The final enzyme activity achieved 81UmL-1, specific activity 78 U mg-1 with purification fold of 130 and recovery 1.

46. Cloning, characterization and expression of a novel laccase gene Pclac2 from Phytophthora capsici
Laccases are blue copper oxidases (E.C. 1.10.3.2) that catalyze the one-electron oxidation of phenolics, aromatic amines, and other electron-rich substrates with the concomitant reduction of O2 to H2O. A novel laccase gene pclac2 and its corresponding full-length cDNA were cloned and characterized from Phytophthora capsici for the first time. The 1683 bp ful

47. Application of decolourized and partially purified polygalacturonase and α-amylase in apple juice clarification
Polygalacturonase and α-amylase play vital role in fruit juice industry. In the present study, polygalacturonase was produced by Aspergillus awamori Nakazawa MTCC 6652 utilizing apple pomace and mosambi orange (Citrus sinensis var mosambi) peels as solid substrate whereas, α-amylase was produced from A. oryzae (IFO-30103) using wheat bran by solid state fe

48. A new enzymatic process for the treatment of phenolic pollutants
This work aimed to develop a new economic enzymatic process to treat the phenolic pollutants using pure tyrosinase in stirred vessel and adopting temperature (T), pH, rotational speed (N), initial phenol (C P,o) and enzyme (C T) concentrations as independent variables. Experimental data of the residual phenol concentration (C P) were used to calculate the ox
