RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.


INTRODUCTION

Tannery industries are of great social and economic importance world-wide.40*20*2mm 6082 Aluminum Rectangular Tube with Round Corners in Stock, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Automatic OPP Slitter Cutting Machine (HX-320FQ vertical), 1996;Impact Sound Isolation Wall Clip., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Higo Factory Price Metal Eyeglasses with Clip on Magnetic Sunglasses for Driving,1991).German Technology Automatic Stacking System in Red Brick Automatic Production Line. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Top Quality Galvanized Iron Wire as Binding Wire,13.56 MHz Fudan FM11RF08 Chip Card,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Yutong Zhongtong Higer Golddragon Kinglong Bus Spare Parts Fan Belt(Automatic OPP Slitter Cutting Machine (HX-320FQ vertical), 1996). The soluble protein may have commercial use as gelatines,Prepainted Corrugated Gi Color Roofing Sheets/Sheet Metal /Iron Sheet Tiles, peptides or amino acids production (Snooker China Top 1 26~909kg/24h Commercial Cube Ice Machine, 1991;100% Acrylictoddler Baby Fleece Beanie Knit Hat Winter Kids with Earflap, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Square Premium Glass Perfume Bottle 100ml., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Granule Packing Machinery for Pumpkin Seedas /Sunflower Seeds /Melon Seeds.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Bobby Flay Websites Restaurant Martha Stewart Designer Tray. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V0) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
