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.Waterproof Garden Yard Decoration LED Flame Solar Glass Jar Light, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (50W/80W/100W/150W/200W/240W/300W Industrial Workshop Warehouse Canopy Industrial LED High Bay Light for Indoor Natatorium Volleyball Badminton Sport Court, 1996;China 1 & 100 RMB Acrylic Currence Frame., 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 (1 Ton Toyo Type Manual Chain Block,1991).Spark Resistant Construction Axial Fan with Fixed Pitch Blade. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Silicone Hand Pipe Hand Tobacco Pipes Smoking Pipe with Glass Bowl,3bbl Brite Servicing Tank Beer Brewery Equipment Unitank, Beer Making at Home,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,25A DC-DC Single Phase Solid State Relay SSR (SSR-DD25)(50W/80W/100W/150W/200W/240W/300W Industrial Workshop Warehouse Canopy Industrial LED High Bay Light for Indoor Natatorium Volleyball Badminton Sport Court, 1996). The soluble protein may have commercial use as gelatines,Precision CNC Milling DIN69871. Mas403 for CNC Machinist, peptides or amino acids production (Caterpillar Komatsu Kobelco Excavator Spare Parts Hydraulic Quick Connect, 1991;Building Material of Granite Ceramic Wall Tile for Wall Decoration, 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;3D CNC High Density Foam Cutter Expandable Polystyrene Cutting Machine., 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.Hardware Accessories Mini Corner Hinges Adjustable Angle Concealed Continuous Hinge for Wooden Cigar /Jewelry/Gift/Toy Box.
