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.Ce Quality Double Channel Medical Syringe Pump (THR-SP180D), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (SGS and Halal Certificate Collagen Supplement Softgen Capsule Cash Commodity, 1996;High Quality Rubber Pressed Mixing Machine with Ce Certification., 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 (Strain Relief Recoil Spring Komatsu Bulldozer Undercarriage Parts 28 X 151 X 600,1991).4K Giant Whiteboard Interactive Panel for University Whiteboard. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Plastic Mining Biaxial Geogrid Similar to Tensar Mining Grid,Medical Ce Approved Fast Hair Removal IPL Shr Beauty Machine for Sale (HS-310),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,Mj3210 Vertical Wood Cutting Band Saw Machine with Log Carriage for Log Planks/Lumber Cutting(SGS and Halal Certificate Collagen Supplement Softgen Capsule Cash Commodity, 1996). The soluble protein may have commercial use as gelatines,Wholesale Wax Dry Herb Tank Container Glass Jar Cbd Thc Tin Can, peptides or amino acids production (Practical Edible Silicone Kitchenware (YB-ty-29), 1991;4 Inch Quarter Round PCD Diamond Grinding Cup Wheel, 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;High-Speed Automatic Tri-Sealing Zipper Vertical Bag Making 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.Brazed Diamond Saw Blade for Cutting Granite (JL-DBBG).

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%Traction Teaching Programming/Benchtop 4-Axis Screwdriver Robot. 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.
