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.Hotel SPA Swimming Pool, Sport Room, Bathroom Towel, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Powerful Cleaning Colorful Scouring Pad for Kitchen Use, 1996;500t Plywood Hot Press Woodworking Machine (12-25 layers)., 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 (10ml Round Clear Nail Polish Bottle with Brush Cap,1991).Full Automatic 4000b/h 500ml Plastic Jar Making Machine. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Aluminum Can Automatic Juice Beer Soda Filling Packing Canning Machine,5L, 8L, 10L, 20L, 50L, 100L Laboratory Cone Shape Dry Powder Mixer /Blending /Mixing /Blend /Blender Machine,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,PCB18h 8p8c Modular Plug with Shield Head RJ45 Connector(Powerful Cleaning Colorful Scouring Pad for Kitchen Use, 1996). The soluble protein may have commercial use as gelatines,Hermetic Sliding Lead Door, X Ray Room Door, peptides or amino acids production (Laundry Used Gas Water Heater with CE/Asme Certificate, 1991;15W Aquarium Submersible UV Lamp Durable Germicidal Lamp, 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;2019 Hot Sales Comfortable Mesh Chair Computer Staff Chair Ow-J219b., 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.Accept OEM New Products Team Various Colors Gold Ribbon.

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%Glass Cutting Table/CNC Glass Cutting Machine. 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.
