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.Stainless Steel Thread Ends Sanitary Butterfly Valve with Pull Handle, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (T Series Bevel Helical Gearboxes for Sale, 1996;Military Police Army Outdoor Protective Safety Bulletproof Camouflage Protective Vest., 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 (Colorful PVC Foam Board with High Density and Customizable Size,1991).Air Vent Diffuser Adjustbable Air Well and Jet Diffuser. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Original Stainless Steel Singer Brand Sewing Machine Needles,Food Grade Window Brown Craft Paper Coffee Compostable Packaging Bag Corn Biodegradable,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,Silicone Rubber Electronic Cable with High Flexibility, High Temperature Resistance(T Series Bevel Helical Gearboxes for Sale, 1996). The soluble protein may have commercial use as gelatines,Dn250-Pn16-10inch-PTFE-Seat Wafer 316-Cast-Steel Double Acting Pneumatic Actuator Butterfly Valve, peptides or amino acids production (Steel Bar Peeling Lathe Machine, 1991;Chemical Product Sodium Gluconate Used for Concrete Admixture, 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;Adding Water Rice Pulping Machine/Soybean Grinding 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.Automatic Double Tea Bag Packing Machinery (Model DXDCH-10B).

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%China Battery Factory Direct Sale OEM 36V 2.6ah Lithium Battery. 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.
