The IFF’s range of SYNERXIA® yeasts may increase
the efficiency of corn conversion into bioethanol by up to three percent. These solutions are already widely used by biofuel
producers in the United States and Brazil, among other countries. According to
the United States Department of Agriculture (USDA), Argentina’s corn ethanol
production is projected to reach nearly 700 million liters and represents over
60 percent of the national bioethanol production in 2023.1 This announcement is
expected to further support the growth of corn ethanol production in Argentina.
Obtained through hybridization combined with
genetic improvement, SYNERXIA® yeasts reduce glycerol formation and provide
maximum ethanol conversion, maintaining high rates until the end of
fermentation. The use of these
yeasts also avoids industrial performance losses caused by the influence of
high ambient temperatures during processing. In a hypothetical example where
fermentation occurs between 37°C and 38°C for seven hours, industrial yield can
decrease by two percent. In a plant capable of processing 1,500 tons/day, the
loss is 8.8 liters/ton, equivalent to 396,000 liters/month. The SYNERXIA®
yeasts exhibit greater resistance and can maintain corn ethanol fermentation
efficiency even under extreme heat conditions.
Currently, IFF is one
of the key global players in biotechnology. These yeasts that enhance
bioethanol processing represent IFF’s innovative approach to ethanol solutions
and are part of IFF’s XCELIS® Ethanol Solutions platform.
The genetically
modified yeasts from the SYNERXIA® family pose no risk to nature and are
certified by regulatory bodies in various countries, including the National
Advisory Commission on Agricultural Biotechnology (CONABIA) in Argentina. The National Service for Agrifood Health
and Quality (SENASA) in Argentina certifies that distillers dried grains (DDG),
a by-product from ethanol production using IFF’s yeasts is also suitable for
use in animal nutrition.
