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.Quality Automatic High Speed Iron Wire Nail Concrete Steel Nail Forming Machine/Coil Nail Machine and Nail Thread Rolling Machine/Nail Twisting Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (New Leaf Shape Pearl Jewelry Wedding Tiara, 1996;Starter Motor 0001367034 12V 3KW 9T for Mercedes., 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 Condition Hongyu Polystyrene Panel CNC Hot Wire Contour Foam Cutte,1991).HPMC Hydroxy Propyl Methyl Cellulose Additives. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Beautiful Smile Cleaning and Whitening Teeth Private Logo Whitening Foam Toothpaste,Tactical Outdoor Hunting Camouflage Rattlesnake Python Airsoft Shooter Suit,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,2019 Hiking Sleeping Folding Beach Air Sofa Lazy Bags(New Leaf Shape Pearl Jewelry Wedding Tiara, 1996). The soluble protein may have commercial use as gelatines,Customized Printed Decorative Mailing Bubble Bags in Bright Yellow Color for Envelopes Packaging, peptides or amino acids production (Large Diaper Bag Backpack, Mokaloo Anti-Water Maternity Nappy Bags Changing Bags with Insulated Pockets and Stroller, 1991;Multi-Storey Light Gauge H Section Steel Beam Framing Building for Workshop, 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;Water Chiller Air Cooled for Cooling Beer Refrigerating., 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.High Quality Cheap Price Disposable IV Infusion Set with Precise Filter.

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%CNC Lathe Main Parts with Good Quality. 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.
