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.9mm/12mm Seven Color Exposed Luminous Pixel String LED, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Construction Scaffolding Steel Galvanized Acrow Prop, 1996;3-in-1 Automatic Bottled Pure Mineral Water Filling Equipment for Gallon Bottle., 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 (Carrier Roller for Sany Hydraulic Excavator Sy16-Sy850h-8,1991).Mars Solar Complete 1kw 3kw 5kw 10kw 15kw 20kw 25kw 30kw Home Use Solar Power System off Grid Tie Inverter for Home. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,AKD Wax 1895/Alkyl Ketene Dimer 1895,22.8V 150W Medical Halogen Lamp,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,Aluminum Conductor PE Insulated Triplex Cable(Construction Scaffolding Steel Galvanized Acrow Prop, 1996). The soluble protein may have commercial use as gelatines,Home Appliance Blender Juicer Motor, peptides or amino acids production (Office Matching Suitable Well-Known Brand Staff Table (HY-NNH-D05-16), 1991;Aluminum Round Circle Disc 1050 1060 1100 3003 for Pot and Basin Aluminum Circle Prices, 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;13 Inch Pneumatic Rubber Wheel Bicycle Wheel with Plastic Rim for Kids Balance Bike., 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.2 Axle Skeleton Trailer 40 FT Container Transport Semi Trailer Best Price.

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%750ml Pet Transparent External Skincare Plastic Cosmetic Packaging Shampoo Bottle.. 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.
