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.Baby Feeding Chair Plastic Chair, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Reflective Hand Hold Thermoplastic Road Marking, 1996;Wide Jaws Adjustable Wrench with Big Grip Multi-Used (FM-W04)., 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 (Wooden Heavy Door All Kind of Stainless Steel Ball Bearing Door Hinge,1991).Food Grade Stainless Steel Threated Butterfly Valve. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,PVC/PP/PE Twin Screw Plastic Granules Extruding Granulator Machine,Zw32m-12 Vcb 12kv Outdoor High Voltage Vacuum Circuit Breaker,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,Suction Function Handheld Cool and Heat Food Bowl for Baby(Reflective Hand Hold Thermoplastic Road Marking, 1996). The soluble protein may have commercial use as gelatines,9.0m Long 26PCS Globe Bulbs Solar Powered G40 LED String Light, for Patio Garden Backyard (Warm white), peptides or amino acids production (JIS S Type Cast Iron Water Filter Dn25, 1991;Machined Self-Locking Trapezoidal Leadscrew, Power Screw, Translation Screw. Left and Right Hand Screws, Split Nut, Half Nut, 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;Factor Direct Adult Sex Toy Doll for Male Sex., 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.C Axis CNC Lathe Machine Tool, CNC Lathe Machine Milling, CNC Lathe Machine Price Servo Turret EL52L.

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%Automotive Acrylic Wholesale Masking Tape Factory Price. 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.
