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.Amazon Inserts Electric Fireplace with Gas Heaters Fan Modern Furniture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Three-Dimensional 3D Fashion Design Wall Covering Material PVC Wallpaper, 1996;Cold Rolled Coated Aluminum Coils 3003 H24 /1060/3004/5052., 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 (High Quality Disposable Blood Transfusion Set with Filter,1991).DIN1478 Closed Body Jaw Jaw Wire Rope Turnbuckle. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic Airtight Sliding Door Radiation X-ray Protection Lead Door Supplier (HF-J194),High Quality Brushless DC Electric Motor for Industrial Deduster,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,China Factory Light Soda Ash /Sodium Carbonate(Three-Dimensional 3D Fashion Design Wall Covering Material PVC Wallpaper, 1996). The soluble protein may have commercial use as gelatines,Regular Size Cigarette Rolling Papers, peptides or amino acids production (304L Stainless Steel U Channel Good Performance, 1991;Solar Photovoltaic Connector Mc4 Connector for Solar System (PV-MC4), 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;Junior Backyard Training Practise Soccer Goal Net., 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.350mm Diamond Blade for Granite.

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%Cast Steel Dual Plate Wafer Check Valve. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
