Enzymes are biological catalysts that bring about chemical changes in substances. With the development of the science of biochemistry has come a fuller understanding of the wide range of enzymes present in living cells and of their modes of action.

Without enzymes, there can be no life. Although enzymes are only formed in living cells, many can be separated from the cells and can continue to function in vitro. This unique ability of enzymes to perform their specific chemical transformations in isolation has led to an ever-increasing use of enzymes in industrial and food processes, in bioremediation, and in medicine, and their production is collectively termed `enzyme technology'. Commercially produced enzymes will undoubtedly contribute to the solution of some of the most vital problems with which modern society is confronted, e.g. food production, energy shortage and preservation, and improvement of the environment, together with numerous medical applications.

The activity of an enzyme is due to its catalytic nature. An enzyme carries out its activity without being consumed in the reaction, and the reaction occurs at a very much higher rate when the enzyme is present. Enzymes are highly specific and function only on designated types of compounds - the substrates.

Glucoamylase is exoenzyme that attacks starch from the nonreducing end of polysacharide chain and fully convert starch into glucose. Some general properties at majority of glucoamylases of microbal origin are distinguished. Glucoamylase is widely widespread in the nature. It is synthesized by many microorganisms and forms in animal tissues, especially in a liver, kidney etc. Glucoamylase is used preliminary for starch hydrolyses in beverages production.

The use of microorganisms as a source material for enzyme production has developed because of different reasons such as there is normally a high specific activity per unit dry weight of product, seasonal fluctuations of raw materials and possible shortages due to climatic change or political upheavals do not occur, in microbes, a wide spectrum of enzyme characteristics, such as pH range and high temperature resistance, is available for selection, industrial genetics has greatly increased the possibilities for optimizing enzyme yield and type through strain selection, mutation, induction and selection of growth conditions and, more recently, by using the innovative powers of gene transfer technology and protein engineering.

The task is to make the best choice of microorganism for production of certain enzyme that gives the highest yield and requires the cheapest raw materials.

As producers of amylolytic enzymes most often use the molds of genera Aspergillus. Presently at the industrial receipt of foods of hydrolysis of starch - decstrose, glucose and fructose syrups, on the stage of saccharification mainly use glucoamylases of producers, related to the species Asp. awamori, optimal conditions of action of which рН 5.0 and...
