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.Aluminum Oxide Non Woven Polishing Wheel for Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (CAT6A FTP Patch Panel (WD6A-012), 1996;LED Light Therapy Beauty Equipment for Skin Care PDT Salon Machine., 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 (Famous Brand Hzs75 Modular Precast Quick Concrete Batching Plant,1991).Famous Brand Luxury Packaging Box Gift Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Qualified Medical Grade Thin Wall Stainless Steel Tube,3D Stereoscopic Network Structure Cermamic Foam Filter for Alumina Foundry,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,High Strength New 0.18mm Molybdenum Wire(CAT6A FTP Patch Panel (WD6A-012), 1996). The soluble protein may have commercial use as gelatines,Structural Synthetic Fiber for Concrete, peptides or amino acids production (LPG Frying Machine Natural Gas Deep Fryer Diesels Continuous Fryer, 1991;Rubber Belt Auto Loading and Unloading Abrasive Blast Cleaning Equipment/Tumblast Shot Blast Machine, 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;Automatic 200-800kg Butterfly Chicken Breast Meat Slicing Machine., 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.Tct Circular Saw Blade for Grass Cutting.

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%CAS 9067-32-7 Hyaluronic Acid/ Sodium Hyaluronate. 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.
