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.Men V-Neck Longline T-Shirt with Color Block Ribbed Trims, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Pan Philps Machine Screw with Flat Split Two Washers Assemblies Custom Fastener, 1996;Anti Haze Pm2.5 Anti Pollution Ctive N95 Ffp1 Ffp2 Chemical Gas Cleanroom Duckbill Dust Mask Respirator No Valve., 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 (Outdoor Multifunctional Solar Power Flashlight (SYSG-517),1991).Automobile Parts Chimney Fiberglass, High Strength FRP/GRP Square Pipe Tube Gh F001 Guohao021 FRP Product. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Rapid Prototyping for Aluminum Parts Sometimes Steel or Brass,High Quality HPMC Hydroxypropyl Methyl Cellulose From Manufacturer,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,FC Bare Fiber Optic Adapter for Network(Pan Philps Machine Screw with Flat Split Two Washers Assemblies Custom Fastener, 1996). The soluble protein may have commercial use as gelatines,3D Printing SLA Protoype, SLA Rapid Prototype, SLA Shoes Prototyping for Auto Accessory, peptides or amino acids production (Cattle Corpse Cremation Burning Stove, 1991;L Shaped Modular Kitchen Designs Kitchen Cabinet on Sale, 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;E26 E14 E17 E17 E39 Lamp Cap Go No Go Gauge., 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.2019 Good Price Screw Press Sludge Dewatering Machine for STP ETP Wwtp Cetp/Water/Waste Water/Sewage/Effluent Treatment.

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%Biodegradable Food Packaging Take out Food Boxes. 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.
