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.Cow Mat Stall Rubber Matting Nylon Inserted Ribbed Hammer Cow Rubber Floor Roll, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Heat Shrink Automatic Flow Wrapping Packing Machine, 1996;Guided Wave Radar Liquid Level Sensor Unaffected by Steam and Foam., 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 (Ductile Iron Standard Brackets Pipe Hanger,1991).Luxury Vintage Throw Pillows Cover for Couch, Damask Pillows Cover, Decorative Pillow Covers. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,ODM Customized Precicion CNC Machining Parts for Stainless Steel Coffee Tamper,5mm-19mm Clear Bent Tempered Glass/Toughened Glass/ Armored Glass/ Reinforced Glass/ Stalinite/ Curved Glass/ Curving Glass Used for Building,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,High Quality Sheet Metal Bending Roll Forming Machine(Heat Shrink Automatic Flow Wrapping Packing Machine, 1996). The soluble protein may have commercial use as gelatines,Different Size Glass Test Tubes, High Quality Laboratory Test Tubes, peptides or amino acids production (Professional Ultrasonic Skin Scrubber Skin Cleansing Radio Frequency Facial Bio Lifting Face Comedo Suction Beauty Machine, 1991;Frame Type Rubber Hydraulic Press Machine, 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;Kitchen Metal Dish Storage Rack (JP-SC984C)., 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.0.45mm Transparent Rigid Pet Sheet Roll for Vacuum Forming.

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%Cnm Single Strand Anchor Coupler. 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 (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
