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.Music Equipment Flight Case/Aluminum Flight Case Hardware/Guitar Effect Pedals Flight Case, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Electric Fabric and Non Woven Fabric Roll Slitting Machine (FQ-1600), 1996;Builtin Video Wall Controller 3X3 LCD Digital Signage Large Video Wall., 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 (Gsx750f Gsf1200 Bandit 01-06 Carb Repair Kit,1991).Charateristic Natural Anodized Aluminium Al6061-T6 CNC Machined Housing for Embroidered Beauty Pen (S-262). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cute Pink Cashmere Soft Plush Lining Warm Bootie,3kw 24V 310mm Vertical Agv Drive Wheel Assembly,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,Sofa Materials PU Leather with Flock Backing(Electric Fabric and Non Woven Fabric Roll Slitting Machine (FQ-1600), 1996). The soluble protein may have commercial use as gelatines,Three Phase 800mm Plate Fan, peptides or amino acids production (ASTM Approved Popular Indoor Trampoline of Park, 1991;Cheap Bent 6mm 8mm 10mm 12mm Clear Curved Tempered Glass for Construction Building, 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;Adjustable Office Commercial Suspended Pendant LED Aluminum Channel Profile for Ceiling Light., 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.Wholesale Genuine Leather Credit Card Mens Wallet.

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%Dbry-320 Christmas Stickers Labels Printing Machine. 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. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
