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.Safe Durable Construction Scaffolding Plank for Building, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Different Size of Ring NdFeB Magnet, 1996;Original Manufacturer Amusement Park Fiberglass Body Battery Powered Adult Bumper Car Game Machine., 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 Welding Structure,1991).Carboxymethyl Cellulose CAS No. 9004-32-4. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Single Phase NEMA AC Motor For Blower Fan/Water Pump/Air Compressor/Agricutural Machine/Corn Thresher,Stamping Parts OEM Gold Plated Copper Piece Copper Terminal for Battery Clip,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,150kg Per Hour Frozen French Fries Production Line(Different Size of Ring NdFeB Magnet, 1996). The soluble protein may have commercial use as gelatines,Automatic Professional LED Display Ceramic Hair Curling Iron, peptides or amino acids production (CNC Machining High Precision A380 Die-Casting Aluminum Auto Spare Parts, 1991;China Gooseneck Lowboy/Low Bed/Lowbed Utility Heavy Truck Tractor Semi Trailer, 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;Vulcanizing Machine /Rubber Tiles Vulcanzing Press., 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.Belt Driven Air Compressor Parts Atlas Copco Double Hanbell Compressors Industrial Air Cooled Screw Water Chiller Low Pressure Oilless Air Compressors Low.

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%Embossing Roller for Tissue Paper. 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.
