The fermentative bacteria are the major competitors of yeast sucrose raw material to be converted into ethanol, very significantly impairing the fermentation yield.

Preventive as well as corrective measures are grounded in a diagnosis and quantification of these contaminants.
Traditional methods such as plating takes around 48 hours so we can have a quantitative diagnosis of these contaminants.
This result for a fermentation process which takes around 8-12 hours does not have more importance in the guise of correcting this fermentation cycle and does not prejudice the terms in this income falls known to 10% of the production capacity of ethanol to values 7%, surely incalculable prejudice if we think of a production-scale as that is what actually happens in the Sugar and Alcohol Mill.
The methodology of KIT MC provides a fast and reliable diagnosis by this method have been validated by previos platings and corrected his series of dilutions with specific bacteria that settle in ethanolic fermentation nutrients.
This rapid diagnosis happens after 30-60 minutes allowing for a correction of this fermentation in time to not have this prejudice and sharp fall in the fermentation yield of ethanol production time.Victory against the time.
