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.Economy Combo Heat Press for Starter, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Long Distance Metal/Plastic Impulse Sprinkler Farm Irrigation Garden Water Sprinkler, 1996;Food Grade Beverage Clear PVC Tubing Hose., 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 (Imee Printing Eco Friendly Promotional Drawstrings Craft Kraft Paper Cardboard Clothing Foldable Shopping Gift Bag,1991).Wet and Wavy Remy Mink Brazilian Hair Weave Bundles Deep Wave. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Luxury Plastic Pump Cosmetic Packaging as Airless Bottle,Top Quality Cheap Fire Resistant PVC Vinyl Flooring for Sports,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,Safety Shoes Anti-Slip Silicone Rubber Crampons OEM Factory(Long Distance Metal/Plastic Impulse Sprinkler Farm Irrigation Garden Water Sprinkler, 1996). The soluble protein may have commercial use as gelatines,45ton Proof Load Testing Water Bag for Life Boat, peptides or amino acids production (Sheet Metal Parts Stamping Processing Cold Rolling Plate Cutting Stamping Bending Precision, 1991;Double Coil Control Solenoid Valve of Butterfly Valve, 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;High Frequency Online UPS W/3W-20K., 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.Solar Collector Panel for Pool Heater.

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%Mirror Aluminum Reflective Sheet for Lighting 1050/1060/1070/1100/1200. 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.
