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.Hexagonal Netting/ Gabion Box/ Gabion Basket, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Proper Price Good Quality 10ml 20ml Airless Pump Bottle, 1996;BSCI Audit Custom 100% Polyester Embroidered Trucker Cap Bottle Opener., 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 (Fire Retardant Reflective Aluminium Foil Woven for Insulation Material,1991).Fireproof WPC Indoor Decorative Wall Panel. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Layflat Water Delivery Hose Discharge Pipe Pump Agriculture Irrigation Tubing 1inch to 10inch,3D Decorative Soundproof Panel Polyester Fiber Acoustic Panel for Interior Wall,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,High Speed PP/PE/PVC SWC Single Wall Corrugated Pipe Extrusion Production Line Manufacturing Machine(Proper Price Good Quality 10ml 20ml Airless Pump Bottle, 1996). The soluble protein may have commercial use as gelatines,CNC Machinery Aluminum and ABS Mock up Prototypes, peptides or amino acids production (Bsp 60° Male Cone Seat Carbon Steel Fittings, 1991;Soccer Field Artificial Grass Cutting Machine for Installation, 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;Plastic Nylon Sheet with High Temperature., 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.PVC TPU Tr 2 Color Sole Injection Moulding Machine.

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%Fashion 925 Sterling Silver Pendants Necklace Jewelry. 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.
