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.ISO 7241-a Bsp Hyaulic Quick Coupling Hose Connectors, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Automotive Acrylic Wholesale Masking Tape Factory Price, 1996;Single Mode Outdoor Armoured GYXTW 2 & 4 & 6 & 8 & 12& 16& 24 Core Fiber Optic Cable Price., 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 (Cheap Rapid Prototype Leather Logo Stamping Mould, Hot Runner Mold with Beryllium Copper,1991).Watermrk Drop in Bathroom Basin Sink. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,OEM ABS Industrial Plastic Sheet Injection Auto Part,15L Big Cooling Cylinder High Production Hard Ice Cream 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,Flange Type Ball Float Water Tank Control Valve(Automotive Acrylic Wholesale Masking Tape Factory Price, 1996). The soluble protein may have commercial use as gelatines,925 Sterling Silver Diamond Jewellery Luxury Gorgeous Nail Ring, peptides or amino acids production (Men Underwear Boxer Briefs Cotton Regular Mens Boxer Briefs Underwear, 1991;Customized Outdoor Plastic Chrome Auto Logo Signs, 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;Small Table CNC Marble Engraver for Stone., 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 Thymosin Beta 4 Acetate Tb-500 Acetate 77591-33-4.

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%KERONG Security Safe Combination Smart Key Card Cabinet Door Lock. 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.
