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

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 Factory Organic Ethyl Ascorbic Acid. 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.
