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.High Efficiency Scc638 Water-Based Cutting Fluid with Factory Production, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Shenzhen LED Screen Manufacturer HD Outdoor P5 P4 P3 Street LED Lighting Display Screen, 1996;High Quality of 2000W Fiber Laser Tube Cutting Machine for Metal Sheet Tube Processing., 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 (Factory Wholesale 1080P HDMI Male to VGA HD15p Female Adapter for PC Tablet Nickel/Gold-Plated HDMI+VGA Connector,1991).New Fashion Style Custom PU Leather Crossbody Women Tote Bags with Wide Strap. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Double Door Heated Holding Carts,2019 New Water Quality TDS Test,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,Top Furniture Hotel Dining Furniture Metal Hotel Table Chair(Shenzhen LED Screen Manufacturer HD Outdoor P5 P4 P3 Street LED Lighting Display Screen, 1996). The soluble protein may have commercial use as gelatines,Container House as Kinder Garden, Modular House as School, Container House for Clinic or Hospital, peptides or amino acids production (Machinery Parts Aeroplane Engine CNC Milling, 1991;Aws E7018 Low Carbon Steel Welding Electrode, 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;Best Price Graphite Electrode with 4 Tpi Nipple RP HP UHP 200-600mm for Smelting., 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.Electrical Bike Waterproof Power Connector.
