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.High Lumen 150W 200W LED High Bay Lighting High Bay LED Light Fixture, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Cog Mono Round Display LCD Module, 1996;TV Stand Carving European LED Lights Heating Fireplace (320SS)., 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 (High Quality Mini LED Flood Light SMD Flood Light 150W,1991).Low Price Fashion Unique Plastic Zipper. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Silica Gel- Indicating Blue to Pink After Adsorption,Offer High Quality Square and Round Cast Iron Manhole Cover,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,White Tight Long Sleeves off Shoulders Celebration Bandage Dress(Cog Mono Round Display LCD Module, 1996). The soluble protein may have commercial use as gelatines,OEM Precision Electronic Industry Machined/Machining CNC Brass Connectors, peptides or amino acids production (4X3200 2mm 3mm 4mm Nc Steel Metal Aluminum QC12y Shearing Machine and Power Shearing Machine, 1991;Road Safety Reflective Waterproof Plastic Reflectors, 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;Mirror 3003 H12 Aluminium Chequered Sheet for Baking Sheet in Hungary., 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.High Quality Gas Spring Strut Gas Shock for Wall Bed.

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%Integrated Hydraulic Steering Control Units (BZZ1F SCU). 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.
