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.Beauty Equipment Skin Care Machine PDT-LED Light Therapy Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Guide IR510 N1 WiFi Handheld Infrared Thermal Imaging Monocular Night Vision Camera for Hunting, Outdoor, Patrol, Search and Rescue 400X300@17μ M, 50Hz, 1996;Camera Storage Digital Hygrometer Dry Cabinet 64L Providing Xeransis Environment., 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 (Industrial Air Cooled Screw Water Chiller 5HP for Thermoforming Machine,1991).Hamsa Design Necklaces Turkish 925 Sterling Silver Hamsa Pendant Jewelry. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,1′′ 1.5′′ 2′′ 25mm 35mm 50mm Double J Latch Hook,Japanese Taiho Brand 4D95 Orignal Crank Main Bearing Excavator Engine Piston M408h Std Size,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,Large Span Steel Structrure for Warehouse From China(Guide IR510 N1 WiFi Handheld Infrared Thermal Imaging Monocular Night Vision Camera for Hunting, Outdoor, Patrol, Search and Rescue 400X300@17μ M, 50Hz, 1996). The soluble protein may have commercial use as gelatines,New Design Steel Prefab Layer Cage Chicken House Poultry Farm, peptides or amino acids production (Garden Solar Stake Lights Outdoor Solar Pathway Lights Waterproof, 14.9X3.3 Solar Landscape Lights for Garden Path, Walkway, Lawn, 1991;2019 Oversized Metal Frame Cat Eye Women Fashion Sunglasses, 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;Men Cross Body Messenger Shoulder Bags 8 Inches 10 Inches., 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.Custom Printed Logo Foldable Cheap Good Quality 250GSM White Brown Fried Chicken Fries Packing Take-Away Kraft Paper Chicken Box.
