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.Deep Hole Cylinder Boring Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Good Prize Solar PV Mounting Panel System for Ground, 1996;Electric Heavy Duty Rail Guided Vehicle for Transportation., 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 (Sower Vacuum Emulsifying Machine for Cosmetic,1991).ASTM A240 309s Stainless Steel Sheet. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Invt Bd 3/5kw Hybrid Solar Power Inverter for Solar Power System Home,Car Mattress Back Inflatable Air Bed Car,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,24K Gold EGF Serum Capsule Anti-Wrinkle Repairing Anti Aging Serum(Good Prize Solar PV Mounting Panel System for Ground, 1996). The soluble protein may have commercial use as gelatines,Automatic Liquid Tomato Paste Sauce Packaging Bag Pouch Packing Machine, peptides or amino acids production (Single Embossed Buttons Membrane Switch with FPC Circuit, 1991;3D Lenticular Postcard 3D Printed Plastic Promotion 3D Gift Card, 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;Popular Laser Cutting Engraving Machine for Nonmetals., 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.Disposable Medical Ventilator Breathing Circuit Anesthesia Smoothbore Corrugated Expandable Circuit.

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%Metal Galvanized Wave Form Perforated Steel Strips. 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.
