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.T5557 T5567 T5577 ATA5577 Thin Card Security Thin RFID Chip Card, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Biogas Desulfurization System/De-Moisture/Pressure Adjust Combined Treatment Equipment, 1996;NBR Latex Adhesive for Glove., 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 (Cheap Wooden House Zinc Plated Angle Bracket,1991).4.2mm 4.8mm Black/Grey Phosphated Drywall Screw with Bugle Head. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Vertical Gv Shaft Dia 18mm 22mm 28mm 100W 200W 400W 750W Medium Gear AC Motor Box,Grid Tie PV Inverter 2-60kw Solar Inverter on Grid 5kw,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,Hot Selling New Popular Stylish Green Large Size Canvas Sling One Side Bag(Biogas Desulfurization System/De-Moisture/Pressure Adjust Combined Treatment Equipment, 1996). The soluble protein may have commercial use as gelatines,Lift off Flag Hinges - Mild Steel with Steel Pin and Ball Bearing Washer, peptides or amino acids production (500 PC Car Body Aluminum Fasteners Trim Moulding Clip Rivet, 1991;12 Inch King Mattress Latex Foam Memory Foam Mattress, 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;A5 PU Cover Loose Leaf Business Diary Book Notepad Notebook., 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.HD Night Vision IR Laser Camera with PTZ for 1200m Surveillance.
