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.Regular Size Cigarette Rolling Papers, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (304L Stainless Steel U Channel Good Performance, 1996;Solar Photovoltaic Connector Mc4 Connector for Solar System (PV-MC4)., 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 (Junior Backyard Training Practise Soccer Goal Net,1991).350mm Diamond Blade for Granite. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Custom Welding Stainless Steel Sheet Metal Welding Parts,Unbreakable 60W 140lm/W 2*1500mm LED Waterproof IP65 Linear Light Lamp,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,Laser ID Card Rigid PET Printing Sheet(304L Stainless Steel U Channel Good Performance, 1996). The soluble protein may have commercial use as gelatines,New Arrival Plush Animal Ride for Kids for Shopping Center, peptides or amino acids production (Professional IPL Shr E-Light Opt Diode Laser Hair Removal Beauty Machine, 1991;(JC-3080) High Quality Clothing Wash Care Ultrasonic Label 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;Ss316 Stainless Steel Heavy Duty Straps., 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.6X420mm Headband Binocular Loupes Dental Magnification Surgical Lightweight Hesperus.

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%2019 Hot Sales Beauty Products Brush Egg Facial Blush Brush Makeup Brush. 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.
