摘要：
The control of the microbial contamination during the sugar fermentation in the processes for obtaining alcohol is a very important action to increase the productivity of the alcoholic fermentation processes. The Saccharomyces cerevisiae yeast cells engage a very tough nutritional competition for the sugarcane juice with the bacteria {Lactobacillus sp and Acetobacter) and the wild yeasts. The proposed composition uses an antimicrobial agent of the guanidine family, such as for example, poly(hexamethyl biguanide), an antibiotic agent, and also a surfactant agent, to prevent the undesired microbial growth. The present invention further refers to the process for controlling the microbial contamination through the use of said agents.
