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.Jqhsp-50*12 Trawl Winch with Automatical Spooling Double Braking, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Fashion Metal Button Crystal Shank Button for Garment, 1996;Small Size Deep Groove Ball Bearing, Miniature Ball Bearing (616)., 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 (10W IP65 Dimmable Recessed Press Steel Fire Rated LED COB Downlight Bezel Interchangeable Fire Rated Down Light,1991).Industrial Laundry Ozone Generator for Jeans, Linen and Gray Cloth Bleaching. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,ABC-508 Brake System Cleaning and Fluid Exchanging Machine,Polypropylene Woven Bag for Sludge Dewatering,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,China Prefab Low Cost Industrial Steel Structure Metal Storage Shed for Sale(Fashion Metal Button Crystal Shank Button for Garment, 1996). The soluble protein may have commercial use as gelatines,High Waist Legging Sports Bra Set Custom Fitness Yoga Wear Women Athletic Wear Set Gym Clothing, peptides or amino acids production (High Quality Industrial Grade Anhydrous Sodium Sulfate, 1991;Professional Factory Supply Design Cat Tree Pet Product, 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;Agricultual Hand Sprayer/Garden Hand Sprayer /Home Hand Sprayer (TF-01F)., 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.Peb Steel Structure Building Materials H-Section I Beam Steel.

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%Na2s2o5 Sodium Metabisulfite (Sodium Metabisulphite) for Fixing Agent. 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.

The total volume (V_t) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (K_av)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: K_av= (V_e- V₀)/ (V_t- V₀) , where V_ewas used for elution volume.
