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.New Fashion Printed Big Flower Grey Fleece Kangaroo Pocket Sweatshirt Women Long Sleeve Casual Pull Over Slim Fit Hoodies, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (12 Teeth Green Painting Steel Rake, 1996;Car Parking or Access Control 2.4 GHz Active RFID Card., 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 (Screw Press Dewatering Machine for Handling The Reject From Paper Mill,1991).C Type Small Simple Power Press Tools Machine with Foot Pedal Switch of Manufactuer Suppliers and Importer for Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,4lz-4.5 Small Tank Kubota Similar Rice Harvester,High Quality Automatic Snack Food Lab Twin Screw Extruder Price,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,Commercial AC Electric Motorized Treadmill 21.5 Touch Screen WiFi HiFi(12 Teeth Green Painting Steel Rake, 1996). The soluble protein may have commercial use as gelatines,IC LED Wire Loop Height Measuring Microscope, peptides or amino acids production (Fan Inside Super Silent Scent Diffuser Machine 120ml Fragrance Oil Aroma Machine Hz-1201, 1991;Heater Blower Motor Fan Switch for VW Santana 32b Lt Polo Coupe Transporter IV Golf I Jetta Audi 80 90 B2 191959511A 321959511A, 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;Stainless Steel Whisky Chilling Stones., 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.Nmsafety TPR Back Cut Resistant Oil and Gas Impact Work Glove.
