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.Small Frame Hydraulic Press Machine for Bending Price, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3.5-7.0g Ozone Generator Purification ---Commercial, 1996;Baby Feeding Chair Plastic Chair., 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 (Reflective Hand Hold Thermoplastic Road Marking,1991).Wide Jaws Adjustable Wrench with Big Grip Multi-Used (FM-W04). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Wooden Heavy Door All Kind of Stainless Steel Ball Bearing Door Hinge,Food Grade Stainless Steel Threated Butterfly Valve,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,PVC/PP/PE Twin Screw Plastic Granules Extruding Granulator Machine(3.5-7.0g Ozone Generator Purification ---Commercial, 1996). The soluble protein may have commercial use as gelatines,Zw32m-12 Vcb 12kv Outdoor High Voltage Vacuum Circuit Breaker, peptides or amino acids production (Suction Function Handheld Cool and Heat Food Bowl for Baby, 1991;9.0m Long 26PCS Globe Bulbs Solar Powered G40 LED String Light, for Patio Garden Backyard (Warm white), 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;JIS S Type Cast Iron Water Filter Dn25., 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.Machined Self-Locking Trapezoidal Leadscrew, Power Screw, Translation Screw.

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%Wheel-Type-Carriage Precision Heavy Duty Linear Guide. 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.
