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.Sodium Lauryl Ether Sulphate 70%/AES SLES 68585-34-2, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Lf + Hf Contactless Smart Hybrid Card, 1996;Pop Custom Cardboard Corrugated Paper Retail Store Floor Display for Sunglasses., 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 (LED Fairy Star Light for All Kinds of Decoration Skylike,1991).Creality Cr-10 V2 3D Printer with Removable Build Surface Plate and UL Certified Power Supply. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Linear Vibrator Screener, for Granule and Powder Selection and Classification,Infant Apparel Coat Toddler Children′s Product Clothes 1-3 Years Old, Infant Cartoon Hoodie Fleece Jacket,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,Children Hardcover Book Printing Services with Free Printing File Checking(Lf + Hf Contactless Smart Hybrid Card, 1996). The soluble protein may have commercial use as gelatines,One Undecylenate Peptide Hormones CAS 13103 34 9 Yellowish Oily Liquid, peptides or amino acids production (Global Brands 10 Year Cheaper Hook & Loop Tape Male Side, 1991;New Long Life Petrol Gas Wood Cutting Machine Hand Manual Garden Field Steel Power Tools CS4500 Gasoline Chain Saw, 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;Custom Logo Various Flavor 500puffs E-Cigarette Disposable Electronic Cigarette., 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.Ep/ Nn/Chevron Heat Resistant Conveyor Belt Rubber Conveyor Belt.

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%500ml PP Sport Water Bottle with Ball. 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.
