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.Ysenmed Medical Hospital Mobile Portable Color Doppler Sonoscape Ultrasound, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Small Blinking Battery Operated Luminary Plastic LED Tea Lights, 1996;Biodegradable Star Sealing Garbage Bag-on-Roll Plastic Trash Bag Making Machine., 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 (Hot Selling Galvanized Bolt for Fixing Cable Clamp on The Pole,1991).Us Standard WiFi Smart Wall Outlet Mini Smart Plug Works with Alexa Google Home American Pattern Mobile Phone Wireless Plug Enabled Voice Control Smart Socket. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Precision Plastic Mold Manufacturer in China,Mango Drying Machine/Solar Fruit Drying 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,Mineral Industry Magnet Ore Ball Milling Machine(Small Blinking Battery Operated Luminary Plastic LED Tea Lights, 1996). The soluble protein may have commercial use as gelatines,DIN934 Hex Nut/304 Stainless Steel Hexagon Nut with DIN933 Hex Bolt/Stainless Steel Bolt and Nut, peptides or amino acids production (Interior Waterproof Decorative Matrial Grey Color PVC Plastic Wall Panel, 1991;Industrial Oil Cooler Titanium  Shell and Tube Oil Cooler  for Water Pump, 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;Blasting Cleaning Shot Peeling Machine Tumble Belt Type., 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.B45 2-Stroke Petrol Grass Cutting Brush Cutter Machine.
