MicroBioGen to present at 37th International Specialised Symposium on Yeasts

Australian industrial biotechnology and yeast innovation technology solutions leader MicroBioGen will be speaking at the upcoming 37th International Specialised Symposium on Yeasts (ISSY37) conference in Adelaide, South Australia, held on 27 November to 1 December.

 ISSY brings together the world’s yeast community and is attended by leading researchers, biotech executives, government, suppliers and professionals in the yeast sector.

 Baker’s yeast, also known as Saccharomyces cerevisiae, is the most used industrial organism underpinning industries worth over US$2 trillion, including biofuels such as ethanol and sustainable aviation fuel (SAF), baking, brewing, wine, and animal feed. It has significant potential in transforming global industries, and with MicroBioGen’s elite yeast strains, has the ability to create a more sustainable future and approach to food and fuels.

 MicroBioGen co-founder and principal scientist Dr Paul Attfield will be speaking at ISSY about yeast applications in decarbonising fuel and food production. The fuel-based transportation sector is a major contributor to greenhouse gases (GHG), and renewable biofuels provide a more environmentally friendly replacement.

Attfield will present a biorefinery model using yeast biomass with high-protein content for food applications that provides significant reductions in GHG emissions, lower fossil energy use, and lower land use in production.

Dr Philip Bell, co-founder and head of research at MicroBioGen, will be speaking at the conference about exploiting the ability of yeast to undergo rapid adaptive evolution.

Bell has a strong background and interest in molecular biology and evolution and has observed that yeast can adapt quickly when placed under selective pressure, a trait which MicroBioGen has leveraged over the past two decades to generate an indexed library of elite yeast strains.

This adaptive plasticity allows yeast to generate improved phenotypic traits (features) in response to selective pressures in the laboratory, leading to an expansion in its industrial utility. 

Geoff Bell, CEO at MicroBioGen, said, “we’re proud to be presenting at, and sponsoring, the 2023 ISSY conference in our home country, Australia, and have the event return to our shores after nearly three decades. Yeast is such an important and wide-spanning organism that underpins diverse industries and plays a crucial role in our sustainable future. MicroBioGen is a world leader in the commercialisation of yeast across a range of industries, and our platform technology continues to deliver financially compelling and sustainable solutions for our partners.”

Kelly Boyd, senior research scientist at MicroBioGen, is presenting on improving Saccharomyces cerevisiae phenotypes for enhanced first-generation (1G) ethanol production. 

Saccharomyces cerevisiae is the primary yeast used in 1G ethanol production, but until recently, the leading yeast strain used in ethanol has limitations around tolerance and resistance.

Kelly will highlight MicroBioGen’s advancements in using genetics to improve yeast characteristics to include higher temperature resistance without damaging performance, enhanced fermentation speeds, and reduced unwanted byproducts in production, and raise the question of the true potential of yeast.

 Additionally, MicroBioGen fermentation team leader and senior bioprocess scientist Sinead Robinson-Cast will present on rapidly and efficiently growing yeast without added vitamins – a huge opportunity to reduce costs. She will showcase MicroBioGen’s novel, ‘vitamin-free’ yeast strains with supporting data.

 MicroBioGen develops elite yeast strains through its world leading ‘yeast innovation as a service’ by leveraging breeding and genetics to enhance or add new characteristics to make yeast more efficient, productive, and resilient.

It has the ability to transform economics and sustainability in diverse industries, from fuel and animal feed to baking and pharmaceuticals, with a 20+ year track-record in R&D and innovation.

Its technology and applications address critical needs in food, fuel, and waste removal, with its biotechnology creating significant opportunities to decarbonise food and fuel production.
