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.2017 China Hot Sale Water Screen Movie Fountain, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Super Quality ESD Soft-Soled Shoes Safety Shoes Cleanroom Anti-Static Boots Work Shoes, 1996;Atlas Copco Ga VSD Air Screw Air Compressor High Quality Stationary Electric Screw Air Compressor., 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 (LED Neon Flex IP67 Waterproof Silicone DIY Neon LED Strip,1991).Best Price Wastewater Treatment STP Treat All Kinds of Sewage to Discharge Irrigation Reuse . Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Individually Paper Wrapped Biodegradable Paper Drinking Straws Wholesale,Latest New Hho Engine Oil Carbon Remover,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,Wood Chips Rotary Dryer Sawdust Pellet Drying Machine(Super Quality ESD Soft-Soled Shoes Safety Shoes Cleanroom Anti-Static Boots Work Shoes, 1996). The soluble protein may have commercial use as gelatines,Delicate Handmade Round Natural Stone Chain Necklace, peptides or amino acids production (Biobase China Vertical Type-Double Doors -25º C Freezer for Best Price, 1991;Christmas Lifting Kinetic Lighting DMX Winch 3D Decorative LED Ball Light, 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;Embossed Aluminium/ Aluminum Household Foil 8011-O., 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 Aluminium Foil for Pharmaceutical, Container, Household, Lamination, Embossing, Sealing, Coating (A8011, 1235, 11100, 8079, 8021).

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%Hot Sale SMD Outdoor P10 LED Display Screen for Advertising (OF10). 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.
