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.Garden Furniture Sofa Rattan Modular Corner Set with Cushions, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Stainless Steel Water Cream Bulk Storage Tank, 1996;Hot Selling Knitting Velvet Jaguar Fabric (JAGUAR)., 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 (Wholesale Women′s Sportswear Leggings Athletic Compression Tight Yoga Pants,1991).Seasoned Cast Iron South Africa Three Legged Potjie Pot. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,1.0g Water and Air Ozone Generator with Silicone Tube,Multifunctional Two Cryopencils RF 40K Cavitation Vacuum Body Slimming Machine,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,16A/24A High Speed Wire Cable Braiding Machine(Stainless Steel Water Cream Bulk Storage Tank, 1996). The soluble protein may have commercial use as gelatines,Traction Teaching Programming/Benchtop 4-Axis Screwdriver Robot, peptides or amino acids production (5 Axis CNC Machine with German Technology (BL-Y850/1050 VMC850/1050), 1991;20 Inch 48V 750W Fat Tire Electric Bike with Double Seat, 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;Agriculture Apple Orchard Reflective Pet Film., 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.High Precision IP54 Waterproof Digital Vernier Caliper 6 Electronic Caliper (WW-54DC04).

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%New Scba Breathing Apparatus Equipment with Ce Certification. 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.
