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.Rotary Vibrating Screen/Sieve/Sifter/Griddle Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (PTZ Camera Two-Way  Audio  Baby Monitor Simple Easy to Operate, 1996;Custom Rubber Product Seal O-Ring /NBR70 O Ring., 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 (Fully Automatic Dust Face Mask Making Machine with Ultrasonic,1991).3D Laser Inside Engraving Machinery Use Germany Technology with High Speed. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Muslim Hijab/Islamic Scarf Fashion Hijab Muslim Scarf,460ml Glassware/Wine /Alcohol/Spirits/Glass Vodka Bottle,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,Ladies Handbag Straw Bag Promotion Crossbody Bag New Fashion Bag Women Leisure Shoulder Bag(PTZ Camera Two-Way  Audio  Baby Monitor Simple Easy to Operate, 1996). The soluble protein may have commercial use as gelatines,New Style Welded Tube Fittings Metric Male O-Ring Tee Stainless Steel Tube Joints, peptides or amino acids production (DIN 7337 Aluminium Core Pulling Stainless Steel Rivet, 1991;Professional Bb Trumpet (ATR6506), 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;Precision Stainless Steel Lost Wax Investment Casting Parts for Agricultural Machines., 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.3.5ton Chinese Engine Gasoline Forklift (FG35T).

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%Workstation Glass Frame Extrusion Aluminum Profiles for Office Partitions. 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.
