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.Cute Pink Cashmere Soft Plush Lining Warm Bootie, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (3kw 24V 310mm Vertical Agv Drive Wheel Assembly, 1996;Sofa Materials PU Leather with Flock Backing., 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 (Three Phase 800mm Plate Fan,1991).ASTM Approved Popular Indoor Trampoline of Park. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cheap Bent 6mm 8mm 10mm 12mm Clear Curved Tempered Glass for Construction Building,Adjustable Office Commercial Suspended Pendant LED Aluminum Channel Profile for Ceiling Light,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,Wholesale Genuine Leather Credit Card Mens Wallet(3kw 24V 310mm Vertical Agv Drive Wheel Assembly, 1996). The soluble protein may have commercial use as gelatines,Yitai Die Making 13mm Beech Rotary Plywood, peptides or amino acids production (Gear Rolling Machine Zh28/25 Spline Hobbing Machine, 1991;OEM ODM Custom Moulding Silicone EPDM Nr SBR NBR Acm NR Rubber Molding Molded Industrial Parts Product Auto Rubber Parts, 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;Men Ankle Business Socks Hot Mens Dress Cotton Socks Wholesale., 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.Partial Thread Steel/Iron Hex Head Self Tapping 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%Petrol Chain Saw Wood Cutting Machine 38cc Chainsaw CS3800. 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.
