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.Firefighting Equipment Aluminum Rescue Tripod with Winch 30m, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Rotor Disc Brake Pad Repair Kit for Wva 29087/29202/29253/29279, 1996;Non-Deformation Kitchen Cleaning Sponge Mesh Sponge Scourer., 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 (Automatic Controller Carbon Steel Sheet Pipe China CNC Plasma Cutter,1991).Cjx2-F (LC1-F) AC Magnetic Contactor. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,30W Portable Vehicle Bomb Moving Signal Jammer for GSM/2g/3G/4G Cellular GPS WiFi Signal,Handmade Stainless Steel Irregular Kitchen Sink Bowl (DF5545XH),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,Fj22082mabts 225mm 220V AC Power Amplifier Cooling Fan(Rotor Disc Brake Pad Repair Kit for Wva 29087/29202/29253/29279, 1996). The soluble protein may have commercial use as gelatines,Aluminum/Aluminium Extrusion Profile Housing for LED Light, peptides or amino acids production (Flexible Stand up USB Charging Stands Cable Phone Charger Holder for Apple iPhone Samsung Huawei Android Phone Holders P0.11, 1991;Single Mode Sc/APC Simplex Fiber Optic Adapter, 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;120da 3-32V DC Output 24~480VAC High Voltage Single Phase Solid State Relay., 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.Double Lines Eco Friendly Automatic Change Rolls HDPE LDPE PLA Corn Starch Trash Garbage Coreless Rolling Smalll Volume Plastic Bag Making Machine.

The final soluble protein shown were used for peptides separations using gel permeation chromatography,Low Price Cmit/Mit14%/Chloromethyl-Isothiazolone as Bactericide/Fungicide.

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%Carbide Mould Parts Moulding Parts. 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.
