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.Oak Veneer Laminated Plywood for Decoration, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (China Factory Produce Custom Logo Printed Cotton Terry Baby Neck Bib, 1996;Hot Sale High Precision Valve Block Hydraulic Flow Control Valve 1wfl., 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 Speed HDMI Cable Wholesale HDMI with Ethernet,1991).Engineer Recommendation Disposable PS Packing Box Mechanical Arm Forming Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,High Quality Women′s Suit in Reasonable Price,Pet Short Fiber Non Woven Geotextile for Landfill Filtration,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,Brown /Black /Red Film Faced Plywood Shuttering Poplar Core Waterproof(China Factory Produce Custom Logo Printed Cotton Terry Baby Neck Bib, 1996). The soluble protein may have commercial use as gelatines,Competitive Price Sodium Gluconate as Concrete Admixture, peptides or amino acids production (Precision Investment Casting Stainless Steel 304 Wire Rope Hook, 1991;AC-1325A-20 Automatic Feeding and Cutting Machine Center of Ball Screw for Furniture, 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;Custom Die Casting Aluminium Product for Connector Usage., 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.Stainless Steel Balustrade/Pillar/Column.

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%Cast Iron Trivet for Tableware Dia: 21cm or Customize OEM. 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.
