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.Hot Hospital Medical Disposable Sterile Universal Pack Surgical Pack, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (14 Heads Double Door Multihead Weigher, 1996;Advanced Optical PCB Tester off-Line SMT Aoi Inspection Machine., 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 (White Marble, Carrara White, Bianco Carrara Marble for Sale,1991).Upper Limbs Machine/Spare Parts for Fitness Equipment. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cvkr Silent Check Valve Dn350,Best Shatterproof Gold Rim Wine Glasses,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,10inch Schedule 40 Carbon Steel ERW Pipe Casing for Water/Well with Black Painting(14 Heads Double Door Multihead Weigher, 1996). The soluble protein may have commercial use as gelatines,High Quality Disposable Barbecue BBQ Mesh Grill Netting Mesh for Korea, peptides or amino acids production (Leather Wallet Slim Front Pocket Wallet Billfold ID Window RFID Blocking, 1991;Relleno De Acido Hialuronico Con Enlace Cruzado Zenfil, 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;20inch Aluminum Folding Bike Pedal Assit Electric Bike with Throttle., 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.Chinese Color Steel Glazed Tile Purlin Roll Forming 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%Scew Weighing Scale Electronic Counting Scale. 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.
