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.Greenshoe Cheap Plain High Ankle Men Canvas Shoes Custom Printed, Men Shoes Canvas Sneakers, Canvas Casual Men Shoes, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cosmetic Grade Matte Chromium Green Oxide for Cosmetics, 1996;Ridge Cap Panel Forming Machine Ridge Cap Making 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 (Grinding Factory Corn Maize Flour Milling Mill Making Machines,1991).Wireless Remote Control Sex Toys Pussy Men Anal Vibrator Prostate Massager for Male. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Construction & Decoration ERW Square Steel Tube Manufacturer,Cold Roll Steel Indoor 19inch 42u Fiber Optic Wetwork Cabinet ,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,Household Use Food Packing 8011 Aluminum Foil(Cosmetic Grade Matte Chromium Green Oxide for Cosmetics, 1996). The soluble protein may have commercial use as gelatines,Solid PVC Forex Sheet 1.22*2.44m White Celuka PVC Foam Board, peptides or amino acids production (25X75m Big Temporary Storage Tent for Storage/ Warehouse Solution on Sale, 1991;Plastic Case Navigation System Tooling Injection Mold, 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;Hy1003 Mixer Shower Set, Luxury Rainfalls Shower Set., 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.8X8mm Silver Expanded Metal Mesh in Hot Sale.

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%Industrial Bridge Crane Remote Hoist Crane Wireless Remote Radio Remote Control System. 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.
