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.Ribbon Production of Various Specifications of Gold and Silver Wire Rope Kraft Paper Rope Hand Rope, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Whole Absorbtion Flexo Printing Soltting Die Cutting Machine, 1996;Factory Price 4X6 Acrylic Magnetic Photo Frame., 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 (200m Diesel Oil Hydraulic Water Well Drilling Machine,1991).Custom Cmyk Printing Cake Gift Packing Box with Lid. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Air Purification Activated Alumina,Steel Tubeless Truck Trailer Rim Wheel (17.5X6.75 17.5X6),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,Resistan UV Grades PP Non Woven Fabric(Whole Absorbtion Flexo Printing Soltting Die Cutting Machine, 1996). The soluble protein may have commercial use as gelatines,New Scba Breathing Apparatus Equipment with Ce Certification, peptides or amino acids production (FRP Pultruded Pipe or GRP Profile, 1991;6090 CO2 Sealed Glass Cooling Laser Cutting Machine, 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;Aluminum Alloy Die Casting Parts LED Lamp Housing Radiator., 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.Sexy Women Dress Invisible Zipper Jump Suits Fashion Hidden Zipper.

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%Factory Supply Straight Ball Joint Bearing 02b04. 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.
