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.Two Sided Lighted Vanity Mirror Folding 1X and 5X or 10X LED Makeup Mirrors, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Yangtze 12V 100ah Lithium Ion 10kw Solar Recharge Battery, 1996;Fabric Coated PVC for Garment Woven Fabric 600d 100% Polyester., 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 (Tct Circular Saw Blade &Diamond Saw Blade,1991).Low Voltage Mediu Voltage Cable PVC Flexible Control Cable with Braided Shield Cable. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Lifting Thread with Needle for Plastic Surgery,Methyl Cyclohexane Methylcyclohexane, Organic Chemicsls,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,LiFePO4 Prismatic Pouch Cell 3.2V 10/20/30/40/50/100ah Flat LiFePO Lithium Battery for Electric Car(Yangtze 12V 100ah Lithium Ion 10kw Solar Recharge Battery, 1996). The soluble protein may have commercial use as gelatines,Fudan Compatible Card 1k RFID Card 13.56MHz, peptides or amino acids production (Happy Cat Tree Condo Pet Scratcher Tower Small Black Sisal Scratch Post, 1991;Biodegradable Food Packaging Take out Food Boxes, 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;Wholesaler 4.3 Inch Mini Tablet PC Industrial Panel PC All-in-One PC Computer., 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.Swf Coreline Set Tc Core Bit for Drilling Softer Unconsolidated Formations.
