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.Stainless Steel Art-Screen for Lobby, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Sm12 Magnetic Level Speed Sensor Usage and Switching Transducer Output Reed Switch, 1996;Fashion Jewelry 925 Sterling Silver Lucky Key Necklace for Women., 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 (Boat Deck Drainage Snow Rubber Flooring/Standing Desk Mat,1991).Coil Sheet Automatic Feeder with Straightener Press Feeders Straighteners Uncoilers 3 in 1 Servo Feed-Straighteners Help to Making Electric Parts. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Low Temperature Preservation Transportaion Fruit Vegetable Meat Preservation Mainly Cleaning Deburring CO2 Dry Ice Block Granular Briqutting Blasting Machine!,2019 Wholesale Electroplate Purple Glass Votive Candle Jar for Holidays,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,Plastic Pet Preform Stretch Blow Molding Machine Blowing Juice Baby Oil Milk Drink Water Bottle Making 4 Cavity Semi Auto PP Jar Manual Medicine Pharmaceutical(Sm12 Magnetic Level Speed Sensor Usage and Switching Transducer Output Reed Switch, 1996). The soluble protein may have commercial use as gelatines,Samples Free! ! ! Primary/Remelted/Refined Lead Ingots, peptides or amino acids production (Printed 10ml 15ml 30ml 50ml Glass Bottle Tincture Carton Paper Box with Custom Logo, 1991;120PCS/M Flexible LED Strip Tira De LED Light Strip, 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;Durable Beige Wood Luxury Vinyl Flooring Dry Back/PVC Flooring., 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.Outdoor Portable Insulated Thermal Tote Cooler Bag for Lunch.
