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.Low Cost Safety Guarantee Storage Silo with High-Efficient Conveyors, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Flb-80125AC Automatic L Type Sealer Sealing Heat Hot Shrink Shrinking Shrinkable Film Wrap Wrapper Wrapping Pack Packing Packer Package Packaging Machine, 1996;PTFE+Bronze Shaft Rod Step Seal Hbts/Spgo Buffer Seal., 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 (500 Tons Hydraulic Power Double Action Press with Cushion,1991).Automatic Loading & Unloading System Tumble Belt Shot Blasting Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Promotional Plastic Laminated Custom Shopping PP Woven Bag,Metal Galvanized Wave Form Perforated Steel Strips,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,Melamine Wooden Like Plate/Bamboo Plate/ Dinner Plate (NK13811-12)(Flb-80125AC Automatic L Type Sealer Sealing Heat Hot Shrink Shrinking Shrinkable Film Wrap Wrapper Wrapping Pack Packing Packer Package Packaging Machine, 1996). The soluble protein may have commercial use as gelatines,Jqx62f Nc 100A 220VAC Coil Voltage Electromagnetic High Power Relay, peptides or amino acids production (Factory Good Quality Coral Fleece Children′s Bathrobes Kids Hooded Bathrobes Wholesale, 1991;Silver Anodized Aluminium I Beam Level Measuring Tool, 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;Bluetooth Sports Watch 116plus Smart Bracelet Incoming Call Pedometer Heart Rate Monitor Blood Pressure Sleep Monitoring., 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.48V25A Lead Acid Battery Maintenance Pulse Charger.

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%Advanced Unlocking Tool for Locksmith. 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.
