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.Metal Hand Folding Machine 1.5mm Aluminum Sheet Manual Bending Machinery, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Quality Electronic Circuit Board Supplier PCB Assembly, 1996;Femo Ferro Molybdenum Powder Lump 55/60., 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 (8W IP65 Waterproof Ceiling Lighting Dimmable LED Down Light Fire Rated Downlight,1991).Round Panoramic Lift, Glass Observation Passenger Elevator. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Painting Road Marking Vehicles Machine for Sale,Automotive Rubber Parts for Any Rubber Material,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,Die Casting Zinc Alloy Badge Use for Car(High Quality Electronic Circuit Board Supplier PCB Assembly, 1996). The soluble protein may have commercial use as gelatines,Hair Twist Sponge Hair Brush Twist Hair Sponge Barber Hair Brush Sponge, peptides or amino acids production (CREE Chip 24W 28W 30W LED Downlight, 1991;Stone PVC Luxury Vinyl Plank Spc Flooring with V Groove, 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;Three Phase 35kv Current Transformer for Indoor., 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.China Shipping Logistics to Stockholm.

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%New Styles Fashion Erotic Women Underwear Sexy Lingerie. 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.
