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.Pure Peptide Powder PT-141 for Enhancing Male Power with GMP (ODM), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (1X4mm2 (12AWG) Solar Cable Red or Black PV Cable Wire Copper Conductor XLPE Jacket TUV Certifiction, 1996;Water Treatment Anthracite., 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 (Heat Treated Welding Protection Glassfiber Cloth Ht800,1991).Fashion European 925 Sterling Silver Butterfly Flower Crystal Engagement Ring. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Reflective Hard Reflector, Relfective Plastic Reflector, Hard Keychain Reflector,Heat Pump Non-Programmable HVAC Room Thermostat,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,Beer Festival Transparent Advertising Glass Beer Cups Beer Mugs Cold Water Glass Tea Juice Bottle Thicken Printed Logo(1X4mm2 (12AWG) Solar Cable Red or Black PV Cable Wire Copper Conductor XLPE Jacket TUV Certifiction, 1996). The soluble protein may have commercial use as gelatines,Reciprocating Automatic Spraying Machine Automatic Wooden Door Painting Machine Standard Reciprocating Painting Equipment Paint Recyclable, peptides or amino acids production (Professional Handheld Underground Gold Metal Detector Waterproof Pinpointer, 1991;Pipe Production Line/ Pipe Used Adjustale or Self Adjustable Pipe Welding Turning Roll/ Rotator, 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;Injector Pump Calibration Test Bench., 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.ASME/ASTM Butt-Welding Stainless Steel Plate Flange.

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%Familu Use Mini Small Pig Feed Pellet Mill. 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.
