Abstract
Enzymes are a very well established product in biotechnology , sales from US have been from $1.3 billion in 2002 to US $5.1 billion in 2009 and is anticipated to reach $7 billion by 2013 . A recent survey on world sales of enzymes ascribes 31% for food enzymes, 6% for feed enzymes and the remaining for technical enzymes . This pattern corresponds to a rise in global demand of about 6% yearly . This includes enzymes required in large scale for application in food and feed [8, ....etc

In this seminar the cadmium™s effect on anti-oxidative enzymes in tomato (Lycopersicon esculentum) plants was evaluated. Plants treated with increasingly CdCl2concentrations (0, 20, 40, 80, 100 and 200 M respectively) were grown in a basic nutrient solution for 7 days. APX (Ascorbate Peroxidase) and GPX (Guaïgol Peroxidase) activities showed to increase below 100 M concentration after treatment. In excessive concentration however, more than determined level, a significant decrease in the enzymes activities was determined. The incr ....etc

APPLICATIONS OF INDUSTRIAL ENZYMES


INTRODUCTION

Enzymes are biological catalysts, organic compounds produced by living organisms that accelerate the transformation rate of substrate to the end product by lowering the activation energy barrier. And these effective catalytic properties of enzymes have already promoted their introduction into several industrial products and processes. Enzymes found in nature have been used since ancient times in the production of food products such as cheese, sourdough, beer ....etc

Enzymes are generally globular proteins and range from just 62 amino acid residues in size to over 2,500 residues. A small number of RNA-based biological catalysts exist, with the most common being the ribosome; these are referred to as either RNA-enzymes or ribozymes. The activities of enzymes are determined by their three-di ....etc
