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.Stainless Steel Expanded Metal Mesh/Aluminum Expanded Metal Mesh, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (24V Ultrasonic Fogger 100mL Aroma Diffuser LED Light, 1996;Home Furniture Set Restaurant King Throne Wedding Banquet Dining Chair., 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 (What′s Kind of Machine for Making Organic Fertilizer Granules,1991).Gsjl 91/1 Multibar Computerized Jacquard Warp Knitting Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Home and Hospital Electric Patient Lift,Coloured Glaze Material and 1000mm Length 333mm Width Fish Scale Asphalt Roofing Shingles,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,M4 Pneumatic Air Driven Liquid Booster Pump Various Good Quality(24V Ultrasonic Fogger 100mL Aroma Diffuser LED Light, 1996). The soluble protein may have commercial use as gelatines,Motorcycle Intake Manifold Carburetor Interface Connector Joint Motorcycle Parts, peptides or amino acids production (DC 12V Power Relay for Smart House, 1991;2019 Good Price Stainless Steel Wedge Wire separation Screen Sieve Bend Screen Filter for Water /Wastewater Treatment, 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;Medical Human Body Thermometer., 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.Patent Product Solar Insect Killer Lamp, Made in Goldsun, China..

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%ACP Aluminium Cmposite Panel Cladding Extrusions. 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.
