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.High Quality 80/ 90/ 100GSM C2s Coated Paper for Printing, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cherry Wooden Grain PVC Film in Furniture, 1996;Shr IPL Elight Hair Removal and Skin Rejuvenation Beauty 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 (Dedi with Samsung LED HD Display 3X3 LCD Did Video Wall Walls 46 Inch 5.3mm Seamless TV,1991).Hot Selling Extruded Aluminum Window Frame and Sliding Door Profile for Curtain Wall (A44). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Agricultural Irrigation Centrifugal Double Suction Diesel Water Pump,Linen Quiltcover Set with Quilting,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,2V250AH OPzV GEL Lead battery Tubular Plate UPS EPS Deep Cycle Solar Power VRLA Battery 5 Years Warranty >20 years Life(Cherry Wooden Grain PVC Film in Furniture, 1996). The soluble protein may have commercial use as gelatines,Trolley Type Bogie Hearth Steel Billets Annealing Heat Treatment Furnace, peptides or amino acids production (Teerte Square Flat Head Self Tapping Screw, 1991;Jdz-1030 High Precision Screen Printing Machine for Satin Ribbon, Cotton Tape, Elastic Tape, Lanyard, 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;Bto 22 Electric Galvanized Razor Concertina Wire for Military., 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.Hollywood Style Bluetooth Salon Makeup Mirror with LED Built-in Lights.

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%304 &314 Stainless Steel Seamless Bending Tube. 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.
