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.8 in 1 3.1 USB C Type C Hub with 4K HDMI Adapter for MacBook PRO, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Load 1600kg Small Machine Room Bed Elevator, 1996;Solid Wood Buffet Storage Cupboard Table Designs Cabinet Sideboard., 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 (Custom ABS Printing Rapid Prototype 3D Printing Parts SLA SLS 3D Printing Service,1991).New Invention 2017 Male & Female Stainless Steel Quick Coupling. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Driving System for Hybrid Stepper Motor Dm860A,Atf-805 Auto Transmission System Flushing Machine with CE/SGS,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,Sand Castings by Gray Iron Material(Load 1600kg Small Machine Room Bed Elevator, 1996). The soluble protein may have commercial use as gelatines,Snf-B/Fdn-B/ Sodium Naphthalene Formaldehyde/ Water Reducing Admixture, peptides or amino acids production (Food Package Aluminum Foil Tray Making Machine, 1991;Business Class Eyeshade Quality Travel Eye Mask Sleeping Eye Cover, 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;Factory Price 6mm Stainless Steel Wire Rope 7*7., 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.Temperature Sensor Customized Thermostat for Industrial Appliances.
