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.High Precision ISO9001 Grinding Milling Turning Motor Cover Manufacturer Precision Parts with Auto Spare Racing Parts, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fashion Design Sleeveless Fitness Wear, 1996;DC Colorful Battery Operated Small Hand Fan for Outdoor Use., 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 (Hsc Heavy Duty 5 Ton Chain Pulley Block,1991).Outdoor Christmas Decoration Highway Street Light. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Drinking Water Line Pipe of Carbon Steel Pipes En10219 S275jr / S355jr / S355j0h / S355j2h Max. 18m Per Each Length,China Cheap Newest 70*77cm XPE Foam 3D Wallpaper,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,48V 200ah UPS Battery Backup for Telecom(Fashion Design Sleeveless Fitness Wear, 1996). The soluble protein may have commercial use as gelatines,450ml Can Beer Tin Take Away 2 Pack Shipped on Beer Tray, peptides or amino acids production (Rustic Burnt Wood Coffee Mug Hanging Rack with 8 Hooks, 1991;5 in 1 Hydra Facial Peeling Micro Dermabrasion Skin Care Skin Whitening Multifunction Beauty Equipment, 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;Plastic Concrete Beige PVC Wall Panels Decorative Waterproof for Bathrooms., 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.8L Mini Fridge Freezer for Home and Car Fridge.
