Abstract

Exocellular polysaccharide production (EPS) is found in many species of both Gram positive and Gram negative bacteria. EPS production by lactic acid bacteria plays an important role in the rheological behavior and texture of fermented milk. The use of EPS which produces lactic acid bacteria has been claimed to provide a thick body and to avoid gel and wheying fractures in fermented milk, which is a problem that often has to be faced by culture milk factories. Furthermore, it has been claimed that EPS isolated from the culture of lactic acid bacteria has antitumor activity. On the other hand a number of polysaccharide bacteria are indicated to have a strong inhibitory effect on AIDS infection. A wide range of polysaccharide bacteria has emerged as an important class of bioactive natural products. It is surprising that over the last few years most scientists have claimed about the possible different effects of EPS bacteria in treating various diseases, such as immune disorders and tumors, and their activity as an anti-inflammatory, anti-ulcer, cholesterol-lowering or antithrombotic agent. In our previous experiments, EPS can improve the quality of sour milk curd, and can be used as a food addiction. The production of EPS bacteria is genetically determined, but it is influenced by the modification of the culture conditions. The purpose of this paper is to provide an overview of EPS produced by bacterial fermented milk starter cultures and prospects for their use in food and health.
