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.Soldering Machine LED Module PCB Hot Air Soldering Station, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (220V/380V/400V/415V/460V/525V Material Handling Equipment Heavy Duty 50 Ton Electrical Chain Hoist, 1996;Aluminum Type-C 3.1 Adapter with 4K HDMI/VGA/SD/TF/RJ45/USB 3.0/Pd 100W., 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 (High Safety Double Wire Security Metal Welded Wire Mesh Fence,1991).Pneumatic Air Driven Liquid Booster Pump. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Heavy Duty Wood Door Calibrating Wide Belt Sander,Magnifying Mirror Shaving Mirror 2X, 3X, 5X, 8X, 10X,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,Aluminium 6061 Electronickelling Laser Engraved CNC Machined Parts UK(220V/380V/400V/415V/460V/525V Material Handling Equipment Heavy Duty 50 Ton Electrical Chain Hoist, 1996). The soluble protein may have commercial use as gelatines,X-Humate 95% Min Super Sodium Humate (Nut Moradant), peptides or amino acids production (Cleanroom Building Material Cheap Price Rock Wool Core Sandwich Partition Board, 1991;Women Summer Swimsuit Chest Zip Bathing Suit, 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;Hemp Seed Oil Body Lotion Moisturizes The Skin., 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.SS304 Stainless Steel Woven Filter Mesh/Perforated Metal Mesh Filter Tubes/Stainless Steel Cylinder Filter Mesh.
