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.Pond Self Priming Booster suction  Water Pump with Pressure Sensor, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (FTTH Field Sc Upc Fiber Optic Fast Connector for Drop Cable, 1996;95g 3D Tooth Stain Remover Whitelock Toothpaste., 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 (Grass Rubber Matting/Outdoor Rubber Mats/Oil Resistance Rubber Mat/Ship Deck Rubber Mats,1991).Al/Pet/Al Double Sides for Aluminium Flexible Air Duct. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,European Standards 100A 24V Electrical Relay for Green Energy,Best Quality Snow Beach Mountain Motorized Electric Bicycles with Pedal,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,Canvas Shoulder Weekend Shopping Big Bag(FTTH Field Sc Upc Fiber Optic Fast Connector for Drop Cable, 1996). The soluble protein may have commercial use as gelatines,High Visuable Reflective Tape for Vehicle Road Safety, peptides or amino acids production (Made in China Aluminum Extrusion Window and Door Profile, 1991;Industrial Mini PC, Support Intel Core3 I7/I5/I3 Processors, Gigabit Ethernet and WiFi. Embedded Ipc, 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;Seaflo 12V 0.7gpm/70psi Mini Electric Garden Pump., 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.304/304L 2b Stainless Steel Sheet and Steel Plate.

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%Thick Wall Large Diameter Aluminium Tube Manufacture. 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.
