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.Atg39 100W LED Flood Light Wall Light Wall Washer, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Manufacturer Premium Outdoor Use Climbing  Plant  Support  Net, 1996;Gold Inlaid 24K Gold / Flowers., 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 (22 Inch Garment Bag Crospack Suit Travel Bag with Shoulder Strap,1991).Permanent Skewed Segment Neodymium NdFeB Magnets with Different Customized Shapes. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Yashi 65inch Infrared Touch Whiteboard Interactive Smart Board,Hydraulic Cutter Bread Machine (ZMF-20Y),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,9 Inch Taxi Headrest Advertising LCD Bus TV LCD Digital Signage Advertising Kiosk Floor Standing Video LCD LED Board(China Manufacturer Premium Outdoor Use Climbing  Plant  Support  Net, 1996). The soluble protein may have commercial use as gelatines,Yet905 Wireless Keypad Doorbell Kits with Remote Control, peptides or amino acids production (Hotel Safe with Digital Keypad and Mechanical Key (ELE-SA200FR), 1991;Original Sinotruk HOWO Truck Parts - Exhaust Pipe Wg9725542042, 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;China Factory Queen Mattress with Visco Memory Foam and Latex., 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.Multi-Port Ss 304 Manual Three Way Non-Retention Ball Valve.

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%2017 Factory Directly Oversized Women Sunglasses. 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.
