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.Kubota Combine Harvester Spare Parts 5h484-2392 Nut, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Nellcor SpO2 Extension Sensor Cable 5 Core SpO2 Adapter Cable, 1996;HVAC Contactor /Air Conditioner Contactor /Definite Purpose Contactor., 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 (Steel Floor Deck Post Cutting Cold Roll Forming Machine,1991).Similar Kavo8000b Fiber Optic Turbine with Water Volume Adjustable Coupling (KV180). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Fluorous Rubber Coated Fiberglass Cloth,Sinotruk Spare Parts Differential Planetary Gear with Part No. Az9231320152,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,280-350-500-550ml Glass Water Bottle with Sleeve (Customized Design Pattern)(Nellcor SpO2 Extension Sensor Cable 5 Core SpO2 Adapter Cable, 1996). The soluble protein may have commercial use as gelatines,PS Foam Disposable Fast Food Box Making Machine, peptides or amino acids production (K Helical Bevel Gearboxes Reducer Motor, 1991;Indoor Customized Electronic Lighted LED Neon Open Sign, 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;Ecofriendly &Economic Jar Manufacture Cute Glass Handle Candy Jar., 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.Fashion Buttons Clothing Accessories Eco-Friendly Nickel-Free Metal Blue Button.

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%(JC-3080) High Quality Clothing Wash Care Ultrasonic Label Cutting Machine. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
