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.Screw Barrel for PVC PPR Pipe Extrusion, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (15kgs/Spool Aws A5.18 CO2 Gas-Shielded MIG Welding Wire Er70s-6, 1996;Gold Open Metal Short Crocodile Wallet for Girl Women Lady., 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 (6kVA Single Phase High Frequency Online UPS with 0.8/0.9 Power Factor,1991).Pond Self Priming Booster suction  Water Pump with Pressure Sensor. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,FTTH Field Sc Upc Fiber Optic Fast Connector for Drop Cable,95g 3D Tooth Stain Remover Whitelock Toothpaste,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,Grass Rubber Matting/Outdoor Rubber Mats/Oil Resistance Rubber Mat/Ship Deck Rubber Mats(15kgs/Spool Aws A5.18 CO2 Gas-Shielded MIG Welding Wire Er70s-6, 1996). The soluble protein may have commercial use as gelatines,Al/Pet/Al Double Sides for Aluminium Flexible Air Duct, peptides or amino acids production (European Standards 100A 24V Electrical Relay for Green Energy, 1991;Best Quality Snow Beach Mountain Motorized Electric Bicycles with Pedal, 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;Canvas Shoulder Weekend Shopping Big Bag., 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.High Visuable Reflective Tape for Vehicle Road Safety.
