5CS™ Fermentation Platform

At the core of GSF’s 5CS™ fermentation technology is GSF’s TenX Bioresin™ ferment media, a proprietary system that concentrates and immobilizes the microbes. TenX Bioresin™ has significant advantages over conventional submerged fermentations

• Increased microbe to solution density, reduced “wash out” and reduced equipment size and costs
• Improved impurity tolerance improves fermentation performance
• Infection risk is lowered, improving yields and up-time

The 5CS™ fermentation technology has the following business implications for the Company

• GSF can utilize off-site production for the ferment bioresin
  • Control of intellectual property; controlling the production of the ferment bioresin reduces the risk of infringement
  • Reduces plant capital expenditures
  • Higher quality control
  • Plant upsets can be dealt with quickly
  • New microbe strains can be easily incorporated
