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.Big Bussiness Project Commerical Chicken Poultry Farm Buildings, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (400t Woodworking Wood Laminate Hydraulic Cold Press Machine Good for Door Making, 1996;Magnetic Separator for Conveyor Belt Self Cleaning Dry Overband Rcdd-20., 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 (New Electric Piston Pump Coating Machine PT6900,1991).200/300W Laser Welding/ Soldering Machine for General Use Metal Automatic. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Quality Estrogen Hormone Progesterone powder one neurosteroid CAS57-83-0,High Quality Crusher for Used Plastic Recycling Line,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,300W/500W Metal Sheet Fiber Laser Cutting Machine Price CNC Router(400t Woodworking Wood Laminate Hydraulic Cold Press Machine Good for Door Making, 1996). The soluble protein may have commercial use as gelatines,Ceramic Bearing Si3n4 608, peptides or amino acids production (Nbm High Quality Auto Part Factory Price 6pk2310, 1991;Tk 4100, Em 4200, Em 4305, T5577 Lw 125kHz RFID Samrt Card PVC Inlay, 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;High Quality Mini LED Flood Light SMD Flood Light 50W., 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.Compatible Datex Ohmeda 545307/545302 ECG Trunk Cable for 3-Lead.

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%Metal Cuting CNC Plasma Cutting Machine (DW1325). 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.
