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 Design Steel Prefab Layer Cage Chicken House Poultry Farm, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Garden Solar Stake Lights Outdoor Solar Pathway Lights Waterproof, 14.9X3.3 Solar Landscape Lights for Garden Path, Walkway, Lawn, 1996;2019 Oversized Metal Frame Cat Eye Women Fashion Sunglasses., 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 (Men Cross Body Messenger Shoulder Bags 8 Inches 10 Inches,1991).Custom Printed Logo Foldable Cheap Good Quality 250GSM White Brown Fried Chicken Fries Packing Take-Away Kraft Paper Chicken Box. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Cast Iron Frame-Plate Chemical Filter Press,Hydrafacial Water Cleaning Skin Peel Facial Beauty Machine,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,Wholesale Personalized Soild Color Sheer Silk Organza Ribbon with Satin Edged for Gift Packaging(Garden Solar Stake Lights Outdoor Solar Pathway Lights Waterproof, 14.9X3.3 Solar Landscape Lights for Garden Path, Walkway, Lawn, 1996). The soluble protein may have commercial use as gelatines,20kg /30kg /50kg/BOPP Laminated Plastic PP Woven Polypropylene Packaging Rice Sack, peptides or amino acids production (One Step HBV 5 in 1 Rapid Test, 1991;Global Sunrise Outdoor Solar Powered Flame Effect LED Lantern Light Solar Lamp, 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;Pig Farm Cast Iron Pig Leakage Dung Floor., 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.Clutch Brake Booster for Yutong Zk6127h Bus.
