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.China Motor Company Produce BLDC Fan Motor for Barn Vent Fan, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Electroless Nickel Copper-Clad Laminate Flexible Multilayer Rigid Double-Sided PCB, 1996;1000 Gallon Stainless Steel Wine Conical Jacket Storage Fermenter Vessel Brewery Brignt Beer Fermentation Tank., 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 (Reliable Stainless Steel 2 Drawers File Cabinet/Office Metal Drawer Filing Cabinet,1991).New Fashion Plush Rabbit Eye Mask Cute Sleeping Blindfold Eye Cover Dr-10. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Soft and Comfortable Velcro Side Tapes for Baby Diaper/Adult Diaper (LSZYT8540),Polymeric Ferric Sulfate (SPFS/PFS) for Water Treatment,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,Rht-060ws Soda Process Water Cooled Screw Type Water Chiller(Electroless Nickel Copper-Clad Laminate Flexible Multilayer Rigid Double-Sided PCB, 1996). The soluble protein may have commercial use as gelatines,Pressed Pipe Scaffold Clamp JIS Ks BS 48.6 Steel Double and Swivel Scaffolding Clamp, peptides or amino acids production (Boat Aluminum Pipe 5083 Marine Used Aluminum Tube, 1991;Imirootree Wholesale Empty 100ml Amber Glass Cosmetic Jar, 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;2017 Year The Newest 7inch LCD Screen Advertising Brochure Video Greeting Cards., 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.Cheap 100% Natural Brazilian Remy Cuticle Aligned Virgin Human Hair.

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%Luxury Hotel Furniture Antique Design Marble Side Table. 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.
