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.Magnifying Mirror Shaving Mirror 2X, 3X, 5X, 8X, 10X, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Aluminium 6061 Electronickelling Laser Engraved CNC Machined Parts UK, 1996;X-Humate 95% Min Super Sodium Humate (Nut Moradant)., 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 (Cleanroom Building Material Cheap Price Rock Wool Core Sandwich Partition Board,1991).Women Summer Swimsuit Chest Zip Bathing Suit. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hemp Seed Oil Body Lotion Moisturizes The Skin,SS304 Stainless Steel Woven Filter Mesh/Perforated Metal Mesh Filter Tubes/Stainless Steel Cylinder Filter Mesh,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,Cost-Effective 10600nm CO2 Fractional Laser Vaginal Tightening Skin Resurfacing and Stretch Marks Removal(Aluminium 6061 Electronickelling Laser Engraved CNC Machined Parts UK, 1996). The soluble protein may have commercial use as gelatines,UTP CAT6 48 Ports Vertical Termination Patch Panel, peptides or amino acids production (Prefab Expandable Luxury Living Container House Prefabricated House, 1991;Custom Printed Paper Cardboard Slidie Jewelry Gift Packing Box, 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;Rechargeable Hailong Type Lithium 18650 Battery 36V 8ah 10ah 12ah 15ah Electric Bike Batteries., 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.Custom Velvet Gift Jewelry Packaging Pouch with Plastic Lock Close.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Electric 510mm Bar Length Dual Action Blade Handy Hedge Cutter Trimmer Fot Tractor. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
