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.Bathroom Makeup LED Mirror Glass with Light, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Green PVC Coated Euro Fence Welded Wire Mesh Fence Garden Fence Euro Wire Fence, 1996;Hot Selling Mini 3D Printer 80mm/S Ender-3 PRO Cheap 3D., 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 (White and Green Board, School Writing Board, School Furniture (GT-76C),1991).Current Precise LED Digital Ammeter. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Automatic Drinking Mineral Water Filling Line/Water Bottling Line,Newest Design Factory Price Brown Leather School Bag Genuine Leather Backpack for Men,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,PP Polypropylene Two Layer Film Blowing Machine(Green PVC Coated Euro Fence Welded Wire Mesh Fence Garden Fence Euro Wire Fence, 1996). The soluble protein may have commercial use as gelatines,Disposable Sugarcane Pulp Paper Bowl 500ml, peptides or amino acids production (Flat Roof Insulation Board Heat Insulation Board, 1991;2018 Single-Sided Printing Ribbon Bow Ribbon Gift Wrapping Ribbon, 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;Custom Female Threaded Tee T Shape Pipe Fittings., 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.Wholesale Soft Hallux Valgus Bunion Corrector Brace for Sport Protection.

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%Crusher for Animal Waste/ Chicken Manure. 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.
