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.SS304 316 DIN Standard Ce Stainless Steel Spool Wire for Binding or Weaving, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Square Shape Glass Candle Holder for One Piece Tealight Candle, 1996;1.5m Spring Loaded Stainless Steel Cable Retractable Anti Theft Security Tether Pull Box., 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 (Medical Autoclavable Surgical Thoracoscopy Trocar,1991).DC 12V 24V Mini Portable Car Refrigerator Compressor Fridge. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Easy Foldable Kids Walking Chair Toys Baby Walker,Men V-Neck Longline T-Shirt with Color Block Ribbed Trims,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,Pan Philps Machine Screw with Flat Split Two Washers Assemblies Custom Fastener(Square Shape Glass Candle Holder for One Piece Tealight Candle, 1996). The soluble protein may have commercial use as gelatines,Anti Haze Pm2.5 Anti Pollution Ctive N95 Ffp1 Ffp2 Chemical Gas Cleanroom Duckbill Dust Mask Respirator No Valve, peptides or amino acids production (Outdoor Multifunctional Solar Power Flashlight (SYSG-517), 1991;Automobile Parts Chimney Fiberglass, High Strength FRP/GRP Square Pipe Tube Gh F001 Guohao021 FRP Product, 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;Rapid Prototyping for Aluminum Parts Sometimes Steel or Brass., 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 Quality HPMC Hydroxypropyl Methyl Cellulose From Manufacturer.

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%Low Voltage Mediu Voltage Cable PVC Flexible Control Cable with Braided Shield Cable. 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.
