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.Linear Guideway Flat Bed CNC Lathe Machine (BL-Z0640), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Economical Residential Home Automatic Aluminum Rolling Shutter Door, 1996;Clear PVC Sheet with Coating for Card., 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 (Classic Black and White Plaid Sling Bag for Women,1991).24 Fiber MPO MTP Breakout Cassette with MPO to LC Cable. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,10L/15L/22L/32L/42L/52L Portable Camping Fridge Compressor Beverage Lcebox Cooler Box Chest Freezer Car Refrigerator Mini Fridge for Car/Home/Outdoor,Free Sample E Liquid/E-Juice for Nicotine Vaping,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,Colored Foil Paper Hot Stamping Heat Transfer Print Package Craft(Economical Residential Home Automatic Aluminum Rolling Shutter Door, 1996). The soluble protein may have commercial use as gelatines,100% Acrylic Knitted Sports Woven Scarf, peptides or amino acids production (Prefab Steel Structure Shed for Storage Warehouse, 1991;Glass Manufacturer/Float Glass/ Tempered Glass (Flat or Curved) for Building / Furniture, 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;Gen 2+ or 3 Day/Night Vision Scope., 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.Waterproofed 4WD Boat Truck Winch 12000 Lbs 12 V Electrical Cable Winch Ce Approved.
