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.Longyi Crimping Types Cable Terminal Lugs, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rigid PVC Foam Board for FRP Marine, 1996;Health Care Showcase Cabinet for Drugstore, Retail Shop Glass Display., 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 (41 Solid Spruce Top Acoustic Guitar with Fishman Pickups (J45),1991).Stainless Steel Furniture Gold PVD Plasma Coating Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Stainless Steel Wedge Wire Sieve Bend Screen Filter for Municipal and Industry Sewage/Waste Water/Effluent/Water Treatment,Steel Pipe Rust Removal Shot Blasting Cleaning 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,Hydraulic Press Corrugated Cold Roll Automatically Forming Machine(Rigid PVC Foam Board for FRP Marine, 1996). The soluble protein may have commercial use as gelatines,2020 Summer Kid/Baby/Girl Dress Cute Cotton Pink Dress with Lace, peptides or amino acids production (Automatic Bread Crumb Processing Line and Making Extruder Machine, 1991;Plastic Water Gas Supply Cable Protect PE LDPE HDPE Pipe Extrusion Machine Line Single Screw Extruder, 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;China Manufacturer Cheap Custom High Precision Spiral Compression Phone Clock Stationery Small Torsion Mechanical Metal Micro Pressure Spring., 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.300ml Clear Hot Water Packing Glass Bottle with Plastic Cap and Silicon Sleeve.

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%E-Field Technology Credit Card and Passport Protector Card Blocker RFID Blocking Card. 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.
