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.New Fashion Diaper Bags Mummy Bag, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Mellow OEM Plastic Pet House Ml-HP004, 1996;12/24V 150ah Power Battery Charger., 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 (1500 Ml Disposable Food Container Brown Kraft Paper Bowl Soup Salad Bowl with Lid (Customized Acceptable),1991).Air Duct Making Machine, HVAC Square Duct Making Machine for Sale. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,China Brass Precision CNC Machining Spare Auto Parts with Competitive Price,Recycled Kraft Food Grade Wholesale Custom Corrugated Paper Pizza Box,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,044866-1 on/off Valve Adapter for Flow Xd Waterjet Cutting Head(Mellow OEM Plastic Pet House Ml-HP004, 1996). The soluble protein may have commercial use as gelatines,Cold Rolled Sheet Table Top Two Burner Gas Stove Jp-Gc203t, peptides or amino acids production (9mm/12mm Seven Color Exposed Luminous Pixel String LED, 1991;Construction Scaffolding Steel Galvanized Acrow Prop, 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;3-in-1 Automatic Bottled Pure Mineral Water Filling Equipment for Gallon Bottle., 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.Carrier Roller for Sany Hydraulic Excavator Sy16-Sy850h-8.

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%Smart Big Hydroponic Indoor Home Garden Planter. 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.
