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.Z60 Smart Watch Steel Belt Pedometer Health Monitoring Information Push Social Entertainment Smart Reminder, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Ground Finish Molybdenum Tzm Rod, 1996;Transparent/Clear BOPP Jumbo Roll., 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 (Yashi 19 270degree Pyramid Hologram Display Showcase Attractive,1991).Chenille Microfiber Mop Head. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Waterproof Pizza Sign Large Advertising Signboard,PVC Shrink Sleeve Label for Drinking Water Bottle,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,Hang on Car Headrest Holder Tablet Cover Case for Xiaomi Pad 4(Ground Finish Molybdenum Tzm Rod, 1996). The soluble protein may have commercial use as gelatines,Galvanized Square Wire Mesh, Metal Window Screen, peptides or amino acids production (Qiankai Anti-Theft Burglarproof Unbreakable Stainless Steel Security Window Screen Factory, 1991;2019 2 Wheel Folding Electric Scooter 5.5inch 24V 250W Foldable Scooter, 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;OEM Customized Stainless Steel Parts by Deep Drawing., 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.Children Bear English Story Book Printing.
