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.Cabinet Shelf Support Pin Furniture Hardware Fittings, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Reasonable Price High Quality Nylon Cable Gland, 1996;Summer White Plastic Handheld Battery Operated Portable Rechargeable Mini Fan., 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 (Disposable Anesthesia Breathing Circuit Tube,1991).High Quality Cheaper Sea Water Magnetic Flow Meter Flange Type. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Volvo Truck Spare Parts Fuel Filter/Caterpillar Filter Element,New Fashion Ladies Genuine Leather Flat Loafers Shoes with Flower 1126,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,Original Auto Parts 612600081334 Wg9100590031 Wg16422401020 for China HOWO Trucks(Reasonable Price High Quality Nylon Cable Gland, 1996). The soluble protein may have commercial use as gelatines,Counter-Clip Fluorine-Lined Butterfly Valve, peptides or amino acids production (DC Brushless Motor for CNC Machine with ISO9001, 1991;Factory Sale 25ton Sinotruk HOWO 6X4 371HP Tractor Head Truck, 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;Road Safety Warning Barricade LED Solar Powered Blinking Light., 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.Manufacturer Customized Plastic Injection Molding.

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%Car Spare Parts Eco-Friendly Stitch Car Foot Mats for Newest Nissan Altima. 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.
