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.Easy Operational Cup Cake Filling Machine, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Used Mini Excavator Komatsu PC55 PC40 PC35 PC15 PC18 Small Digger, 1996;Folding Play Mat Crawl Play Mat., 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 (Wooden Grain Perforated Panel for Metal Mesh Curtain Wall,1991).Reasonable Price and Fast Delivery Yk11/Yk-11 1370003-76-1. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Folding Platform Hand Trolley ,Pump Flower Sprinkler with Automatic Watering System,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,Catering Use Cafe Use Tolix Outdoor Metal Dining Chair Restaurant(Used Mini Excavator Komatsu PC55 PC40 PC35 PC15 PC18 Small Digger, 1996). The soluble protein may have commercial use as gelatines,Security RFID Protection E-Shield Card RFID Blocking Card for Proximity Identification Field, peptides or amino acids production (Low Carbon Heavy Galvanized Steel Wire, 1991;Long Distance Measurement Power Laser Digital Meter, 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;Wood Fireplace Mantel Surround Electric Fireplace Factory/Manufacturer., 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.Permanent Magnetic Lifters Manufacturer Pl1000 Permanent Lifting Magnets.
