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.Yashi 65inch Infrared Touch Whiteboard Interactive Smart Board, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hydraulic Cutter Bread Machine (ZMF-20Y), 1996;9 Inch Taxi Headrest Advertising LCD Bus TV LCD Digital Signage Advertising Kiosk Floor Standing Video LCD LED Board., 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 (Yet905 Wireless Keypad Doorbell Kits with Remote Control,1991).Hotel Safe with Digital Keypad and Mechanical Key (ELE-SA200FR). Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Original Sinotruk HOWO Truck Parts - Exhaust Pipe Wg9725542042,China Factory Queen Mattress with Visco Memory Foam and Latex,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,Multi-Port Ss 304 Manual Three Way Non-Retention Ball Valve(Hydraulic Cutter Bread Machine (ZMF-20Y), 1996). The soluble protein may have commercial use as gelatines,Convenient Operation Hard-Wearing Smooth Feeding Biodegradable Bagasse Pulp Tableware Plate Making Machine/Former/Maker, peptides or amino acids production (HD Night Vision IR Laser Camera with PTZ for 1200m Surveillance, 1991;Ceiling Mounted IV Stand Stainlesss Steel I V Pole, 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;Pipe Connection Types of Pressing Scaffolding Universal Clamp., 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.Ml33-2mm Eddy Current Linear Position/Displacement Sensor.

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%Promotional Multi-Function CO2 CNC Control Table Laser Cutter Engraving Supplier. 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.
