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.NBR EPDM Neoprene Silicone Rubber Sheet for Seal, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Commercial Coca Cola Refrigerator with Glass Door, 1996;Flyscreen Anti-Mosquito Mesh18*16/Inch Government Company., 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 (Double Jacketed Cooking Kettle Electric Jacket Boiler,1991).Fashion Gray Leggings Stretch Fitness Work out Pants for Women. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Hot Sale/HPMC/Clear/Empty/Vegan/Vegetable/Gel/Hard/Pullulan/Vegan Capsules,High Quality Wafer Type EPDM/NBR Seat Fluorine Lined Butterfly Valve,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,Medical Grade Ventilator for Sleep Apnea Breathing Machine(Commercial Coca Cola Refrigerator with Glass Door, 1996). The soluble protein may have commercial use as gelatines,UV Resistant Single Component Water Based Polyurethane Waterproof Coating, peptides or amino acids production (Steel Rubber Seal for Dust Proof, 1991;Industrial Steel Structure Mezzanine Rack Platform System/Book Shelf, 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;Kindergarten Playground Preschool Kids Plastic Slide and Swing., 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.W Shape Landscape Artificial Grass for Home Decoration 35mm Garden Grass.

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%5.5 to 7.5kw AC Frequency Inverter for Motor AC Drive. 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.
