NATRUCAN

Technical Information

What is it? • Natrucan is a patented formulation that combines natural surfactants with organic

acids.

• It works in the presence of organic matter and soil and is more effective than chlorine and peracetic acid.

• The combination of active substances provides a broad spectrum of antibacterial action without affecting the viability of yeasts.

• The ingredients used in the composition of NATRUCAN are GRAS certified and approved for use in foods, which allows fermentation byproducts, such as yeast, to be used for animal feed at no risk.

• Safety: The product is non-toxic, non-corrosive and poses no risk either to those who handle it or to the environment.

How does it work?• Mode of action:

– Reduction of pH, causing rupture of the bacterial cell wall.– Alteration of cellular metabolism (fatty acids).– Bactericidal effect.– The stipulated doses do not affect yeasts because their cell walls have

a different composition (chitin), providing greater resistance.

Spectrum of Action

• In view of its effects on the cell wall and on bacterial metabolism, this product has a broad spectrum of action, covering both G+ and G- bacteria.

• It does not lead to generation of resistant populations of microorganisms.

Indications

• Natrucan is indicated in the control of bacterial contamination in alcoholic fermentation and improvement of yields in the ethanol production process.

• Dose: 75 - 150 ppm

Studies conducted in Brazil

• In vitro studies

• Pilot-scale trial

• Industrial-scale trial

In vitro studies

• Evaluation of different doses and impact on:– Bacterial contamination– Viability of yeasts

• Conclusion:– Product reduced bacterial contamination without

impacting the viability of yeast.– Dose defined for the pilot study: 150ppm

FINAL CONSIDERATIONS

• NATRUCAN has proven to be efficient in controlling bacterial contamination in the ethanol fermentation process, without any negative effect on the viability of yeast

• The product has proven to be efficient under different industrial conditions:– Different levels of contamination;– Different microflora;– Different yeasts.
