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.PVC Car Seat Belt Shoulder Protector 80438, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Twin Screw Floating and Sinking Fish Shrimp Food Feed Making Extruder, 1996;Professional Full Automatic Machine for Making Wood Pellets., 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 Quality 20PCS Colorful Makeup Brush Set,1991).Big size 420mm*420mm*460mm building plate,printing Rehabilitation of protective, 3D Printer used in rehabilitation therapy. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,PE Plastic Road Safety Barricade Caution Tape,Screw Barrel for PVC PPR Pipe Extrusion,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,15kgs/Spool Aws A5.18 CO2 Gas-Shielded MIG Welding Wire Er70s-6(Twin Screw Floating and Sinking Fish Shrimp Food Feed Making Extruder, 1996). The soluble protein may have commercial use as gelatines,Gold Open Metal Short Crocodile Wallet for Girl Women Lady, peptides or amino acids production (6kVA Single Phase High Frequency Online UPS with 0.8/0.9 Power Factor, 1991;Pond Self Priming Booster suction  Water Pump with Pressure Sensor, 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;FTTH Field Sc Upc Fiber Optic Fast Connector for Drop Cable., 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.95g 3D Tooth Stain Remover Whitelock Toothpaste.

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%Air 2 Bluetooth 5.0 Wireless Earbuds Noise Canceling Sports Earphonesfor iPhone/Android Apple Airpods. 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.
