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.Eco Friendly Heat Sealing Small Capacity Garbage HDPE LDPE Trash Biodegradable Plastic Bag Making Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Output Plastic Rubber Filing Masterbatch Extruder Machine, 1996;High Precision Mold Manufacturer Plastic Injection Mould., 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 (China Wholesale Oxide Aluminium Black Sand Blast Media,1991).Welded Stud Anchor Chain for Ship. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,SGCC Cold Rolled Z180 Coating Galvanized Metal Steel Strip for Industry,Line Scan Uvss System Portable Under Vehicle Surveillance,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,Folding Steel Manual Wheelchair with Chrome Frame(High Output Plastic Rubber Filing Masterbatch Extruder Machine, 1996). The soluble protein may have commercial use as gelatines,Piston Cooling Nozzle Valve Body Made of 45# 35# Carbon Steel, peptides or amino acids production (Fashion Style Lady Alloy Quartz Watch with Simple Dial, 1991;Rooftop HVAC Packaged Units (RTU) Amrta Manufacture, 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;Waterproof IP67 Outdoor Plastic Box Enclosure Electronic Junction Box., 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.Building Decoration Material Acrylic Dispersant for Coating.

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%Universal Wholesale Hot Sale Custom Blank Keys. 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.
