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.Heat Shrink Automatic Flow Wrapping Packing Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Guided Wave Radar Liquid Level Sensor Unaffected by Steam and Foam, 1996;Ductile Iron Standard Brackets Pipe Hanger., 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 (Luxury Vintage Throw Pillows Cover for Couch, Damask Pillows Cover, Decorative Pillow Covers,1991).ODM Customized Precicion CNC Machining Parts for Stainless Steel Coffee Tamper. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,5mm-19mm Clear Bent Tempered Glass/Toughened Glass/ Armored Glass/ Reinforced Glass/ Stalinite/ Curved Glass/ Curving Glass Used for Building,High Quality Sheet Metal Bending Roll Forming Machine,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,Different Size Glass Test Tubes, High Quality Laboratory Test Tubes(Guided Wave Radar Liquid Level Sensor Unaffected by Steam and Foam, 1996). The soluble protein may have commercial use as gelatines,Professional Ultrasonic Skin Scrubber Skin Cleansing Radio Frequency Facial Bio Lifting Face Comedo Suction Beauty Machine, peptides or amino acids production (Frame Type Rubber Hydraulic Press Machine, 1991;Kitchen Metal Dish Storage Rack (JP-SC984C), 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;0.45mm Transparent Rigid Pet Sheet Roll for Vacuum Forming., 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.AVR Se350 Automatic Voltage Regulator for Marathon Alternator.
