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.Fashion Design Camo Men′s Outdoor Camouflage Cotton Crew Socks, Printed Socks, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Full Hard S550gd Cold Rolled Galvanzied Steel Sheet in Coil, 1996;Felt Disc Polishing Sanding Disc with Wool Felt Diam., 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 (13.56MHz Contactless RFID Card MIFARE 1K Card for Prepaid Payment System,1991).Thermomolded TPE 5X20mm IP68 10K Air Conditioner Probe Black Cable. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,100% Fiberglass 1*1m Fire Blanket 3732 Fiberglass Cloth,240T goodeng water/oil/gas pipe drilling rig HDD machine,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,Mens Messenger Bag 15.6 Inch Waterproof Waxed Canvas(Full Hard S550gd Cold Rolled Galvanzied Steel Sheet in Coil, 1996). The soluble protein may have commercial use as gelatines,Colored Silicone NBR O-Rings Seals, Rubber O Ring with High Strength, peptides or amino acids production (Reinforced Stainless Steel 306L Wire Wrap Johnson Type Strainer Screen, 1991;Colorful Braided Fabric Cable Round, 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;Universal Wholesale Hot Sale Custom Blank Keys., 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.Latex Free Olive Face Cut Makeup Sponge /Oval Makeup Sponge Not Makeup Remover Sponge.

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%China Supplier Hot Sale Electric Hydraulic Vertical Freight Lift with Cheap 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.
