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.CNC Machined Power Transmission Shaft Part, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Repalcement Car Key Case for Brazil Alarm 4 Button Remote Key Blank Cover Shell, 1996;Good Price Channel Steel Used for Machinery., 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 (Diesel Engine Spare Parts for Generator Spare Parts China Diesel Generator,1991).Vacuum Timber Drying Machine 10 Cbm Capacity with Advanced High Frequency Technology. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hot Sell with 12 Sets Hose Crimping Tool 220V 4-51mm with Big Discount,Factory Direct Sale Patent up to Down Rubber Tile Curing Press,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,Quality Ep / Nylon/ cotton Fabric Rubber Conveyor Belts Used in Coal Mine Made in China(Repalcement Car Key Case for Brazil Alarm 4 Button Remote Key Blank Cover Shell, 1996). The soluble protein may have commercial use as gelatines,Real Leather Wallet Mens Designer Leather Wallets, peptides or amino acids production (Auto Bearing Sleeve Ball Bearing Tapered Adapter Sleeve H3936 H3136 H 2336 H3938 H3138 H2338 H3036 (OH3036HB OH3136 OH2336 OH3838 OH3138 OH2338), 1991;Full Port Small Automatic Electronic Plumbing Ball Valve, 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;Screw/Countersunk Head Screw 6 Ribs with Wing, Csk Wing Screw,., 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.Cleanroom White PVC Dotted Anti-Static Gloves.

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%Craft Socket & Wrench Tool Set Car Repairing Tools 94PCS. 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.
