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.Price of a Retail Supermarket Push Cart for Sale, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Indoor UTP Cat 6 with Rj 45 Connector Length 20 Meter Cable, 1996;OEM Stainless Steel Stamping Parts Custom Stainless Steel Sheet Fabrication Metal Stamping Fabricate., 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 (Handmade Natural Bamboo Basket / Bamboo Flower Pot,1991).Stainless Steel Handrail Bar Holder for 16mm Pipe. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Shac Flange Linear Bearing,China Supplier Hot Sale Electric Hydraulic Vertical Freight Lift with Cheap Price,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,Heat Resistant Adhesive Teflon Tape Price High Temperature Teflon Tape(Indoor UTP Cat 6 with Rj 45 Connector Length 20 Meter Cable, 1996). The soluble protein may have commercial use as gelatines,CNC Router for Engraving Cutting Carving Drilling Milling, peptides or amino acids production (Electric Manual Ice Crusher Ice Shaver Industrial Ice Machine, 1991;Horizontal Rustproof Multi-Function Blood Storage Refrigerator Yj-40-60-Wa, 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;Empty 20ml Pocket Perfume Spray Bottles 20 Ml PP Plastic Card Shape Bottle with Sprayer., 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.High Quality Hot Rolled Steel U Channel China Supplier.

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%Jcb Spare Parts for 3cx and 4cx Oil Cooler 923/02700. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm.
