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.Digital Programmable Ntc Temperature Controller, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Water Meter Spare Parts Rubber Rings for Sealing, 1996;Stainless Steel HK Series Needle Roller Bearing HK0408., 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 (Road Construction Fabric Non-Woven Geotextile 200GSM,1991).High Polymer Modified Cement Based Elastic Waterproof Coating. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Best Thermal Insulation Material Aerogel Powder for Greenhouse Steam Pipe,Heat-Sealed Laminated Bag with Hexagonal Bottom Gusset,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,Fashion Shoulder Backpack Handbag School Bag(Water Meter Spare Parts Rubber Rings for Sealing, 1996). The soluble protein may have commercial use as gelatines,Coating Application CMC / Coating Material Grade CMC LV, Mv, Hv / Coating Material Grade CMC Medium Viscosity, peptides or amino acids production (Hot Sale Cute Food Plastic Pet Slow Feed Dog Bowl, 1991;FTTH Fiber Optic Fusion Splicing Toolkit, 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;High Speed Cable Wire Winding Braiding Machine., 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.22 High Rubber Mixing Mill, High Accuracy Lab Rubber Two Roll Mill.

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%Pharmaceutical Peptide Ghrp 2 Acetate CAS158861-67-7 Ghrp-2. 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.
