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.High Performance Fresh Air Handling Unit for Marine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Community IC Access Card Induction ID Time Card Smart Card, 1996;Food Packing Machine Biscuit Packing Machine with Auto Feeder., 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 (High Quality Rolamento Agulha Needle Roller Bearing HK1512 HK2020 HK2030 Bearing,1991).Military Uniform ISO and SGS Standard for Army Camouflage. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,300W-2kw Solar Panel and Wind Turbine Hybrid System,EVA Sheet Foaming Shoe Sole Hydraulic Press Vulcanizing Machine,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,Top Quality Inox Plumbing Sanitary Stainless Steel 304 316 Press Fitting Fittings Water Meter Fittings Hose Quick Connector(Community IC Access Card Induction ID Time Card Smart Card, 1996). The soluble protein may have commercial use as gelatines,Used Japanese Mini Excavator Komatsu PC55mr Digger with Rubber Track, peptides or amino acids production (RV UPS Power 48V 80ah LiFePO4 Battery Pack, 1991;Popular Cheap Custom Logo Black Silicone Wristband in High Quality, 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;Factory Good Quality High Precision Machined Milling CNC Brass Parts., 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.Volatile Oil, Plant Extracts, Feed Antibiotic Substitutes.

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%TP304L Stainless Pipe /Heat Exchanger/Condenser Tube;. 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.
