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.Soft magnetic alloy 1J38 rod / Ni38Cr13/38H14X, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (High Current Temperature Rising Test Large Current Temperature Rising Test System, 1996;Animal Manure Fertilizer Fermentation Machine., 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 (Compact New Design IP65 Toggle Limit Switch,1991).Teflon for Industrial Plastic Gasket Seal with Good Quality. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Double Walled Stainless Steel Insulated Water Bottle,Wineglass Crystal Glass Snow White Mousse Pie Juice Cup Red Wine Glass,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,2018 Cheap PU Leather Bracelet in Alloy Jewelry(High Current Temperature Rising Test Large Current Temperature Rising Test System, 1996). The soluble protein may have commercial use as gelatines,China Laboratory Arm Fume Hood/Arm Fume Extractor/Mobile Exhaust Hood, peptides or amino acids production (Damage Recovery Pharmaceutical Peptides Chemical Medicine Tb-500, 1991;Competetive Price Tension Springs for Stapler, 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;Aramid Felt Teflon Felt Non-Woven Nomex Needle Punched Machine/ Felt Polishing Wheel Polished Felt CNC Digital Cutter Textile Felt Making Machine., 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.Men Casual Short Pants Custom Quality Running Sports Wear Shorts.

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%2 Axle Skeleton Trailer 40 FT Container Transport Semi Trailer Best Price. 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.
