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.Electric Paint Sprayer Pump, Cylinder Liner, Piston Rod with Repair Kits for Wagner 940/950, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Magic DIY Bouncing Heat Sensitive Thinking Putty Intelligent Play Dough Toys, 1996;600*600mm 800*800mm CO2 Laser Carving Machine for Paper Metal Tube., 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 (High Quality Cacao Bean Grinder Cocoa Butter Making Machine,1991).Nh4cl White Granular Agricultural Grade Ammonium Chloride. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Concrete Aluminum Formwork System Aluminium Formwork,Office Drawer Cabinets Office Furniture Accessories Fittings Seal Edge Banding,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,Men′s Leather Loafers Shoes Driving Loafer Men Dress Shoes(Magic DIY Bouncing Heat Sensitive Thinking Putty Intelligent Play Dough Toys, 1996). The soluble protein may have commercial use as gelatines,High Quality Spooling Pet Polyester Mylar Film for Cable Material, peptides or amino acids production (Irrigation Hydroponics System Planting Tools Film Greenhouse for Agriculture/ Farming, 1991;Creative Beautiful Flower Design Metal Promotion Gift Medal of Souvenir, 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;2019 High Quality 12V 3.1A Quick Charge QC 3.0 Phone Charger 2 USB Port Car Charger Custom Logo., 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.Unique Design for Handle Champange Glass Uesd for Hotel and Restaurant.
