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.New Condition Textured Peas Soy Protein Making Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Hot Sale Tractor Engine Spare Parts Injector Nozzle for Mf 240 OEM No Dll 150s6556, 1996;5PCS Travel Mini Eye Makeup Brushes Set Eyebrow Brush Make up Brushes., 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 (SBR Round DOT Horse Stall Mat, Rubber Stable Mat,1991).Customized Frame Mount Highway Pegs Enclosure Parts. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Double Wine Carrier Bag Gift Box Tote,IP44 Waterproof 3pin 16A Electrical Male and Female Industrial Plug and Socket,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,40*60cm Top Coated White Direct Thermal Bar Code Paper Sticker Labels for Rolls(Hot Sale Tractor Engine Spare Parts Injector Nozzle for Mf 240 OEM No Dll 150s6556, 1996). The soluble protein may have commercial use as gelatines,RF Coaxail BNC Male to BNC Male Plug Connector Adapter, peptides or amino acids production (Gt4b63 Can Seamer Machine, 1991;Illuminated Designed Light Sensor Demister Touch Switch LED Bathroom Mirror, 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;Glazed Metal Roof Tile Roll Forming Machine with Ce., 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.Industrial Packing Paper Pulp Tray Making Machine Egg Tray Making Machine.

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%Handheld Andriod POS with Thermal Printer. 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.
