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.Custom Grooved Quartz Plate Deep Processing, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale CNC Router Machine for Wood Cutting (1325), 1996;Efficient HDPE LDPE Polypropylene Film Blowing Machine Strech Film Machine., 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 (50g Body Luxury King Crown Cosmetic Containers,1991).Custom Logo Stainless Steel Quality Wrist Quartz Watch for Men. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Mini Succulent Planters, Cactus Pots with Wooden Cement Pot,Paper Egg Box Forming Molding Production Line/ Egg Tray 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,4K LED TV Panel Laser Repair Machine Cr-512dh Big Size Panel Repairmachine/LCD Screen Repair Machine(Hot Sale CNC Router Machine for Wood Cutting (1325), 1996). The soluble protein may have commercial use as gelatines,Tan Color Strip Aluminum and Glass Mosaic for Wall (M855330), peptides or amino acids production (CNC Metal Grinding Machine Tool Mk2120, 1991;Removable Triangular Single Slot Metal Folding Down Shelf Wall Support Bracket, 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;Hot Sale High-Order Elasticty Girls Sports Wear Yaga Suit., 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.Cast Iron Trivet for Tableware Dia: 21cm or Customize OEM.
