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.Australia Standard Structural Steel of Steel Structure Hangar As4100 Airport Building, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Dark Red Teflon Encap Silicone O Ring, PTFE Encap Silicone O Ring for Industrial Seal, 1996;Custom Make Promotional Gift Agenda Diary Notebooks as Your Company Logo., 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 (N52 Strong Disc Neodymium Rare Earth Permanent Industrial Cylinder Magnet,1991).Bulk Packing 20kg Double Plastic Bags Outer Carton Peanut Butter (Peanut Paste). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Remy Human Hair Straight 1b#613 Full Lace/Lace Front Wig on Sale,High Quaity China Supplier Truck Trailer Auto Car Accessories,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,Factory Manufacturers Uni-Loose Tube All Dielectric Optical Cable GYFXTY-Fg 2-24 Fiber Drop Cable(Dark Red Teflon Encap Silicone O Ring, PTFE Encap Silicone O Ring for Industrial Seal, 1996). The soluble protein may have commercial use as gelatines,Cheap Christmas Decoration Micro LED Mini Christmas String Fairy LED Wire Copper LED Light, peptides or amino acids production (Custom Steel Investment Casting High Hardness Agricultural Machinery Parts, 1991;Minimalist Slim Real Leather Front Pocket Card Wallet, 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;Natural Cleaning Konjak Sponge., 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.Indoor Load Break Switch Isolating Switch.

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%Steel Pipe Rust Removal Shot Blasting Cleaning Machine. 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.
