Biojet Test Flight Program to Use Calyx's Operating Subsidiary's Carinata Feedstock

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 18, 2012) - Calyx Bio-Ventures Inc. ("Calyx" or the "Company") (TSX VENTURE:CYX) is pleased to announce that it's partially-owned operating subsidiary, Agrisoma Biosciences Inc. ("Agrisoma"), has unveiled the first comprehensive flight program in the world to use biojet fuel produced from Agrisoma's proprietary Resonance™ brand Carinata Energy Feedstock.

Resonance is a new industrial oilseed crop, derived from Brassica carinata, with an oil profile optimized for use in the biofuel industry, specifically biojet fuel. The program will evaluate Honeywell Green Jet Fuel™ refined from Resonance feedstock oil produced in Saskatchewan. The flights, conducted in partnership with the National Research Council ("NRC") in Ottawa with funding from the Government of Canada's Clean Transportation Initiatives, will evaluate the Resonance-based biojet fuel under a number of flight conditions to provide the world's first ever real-time, in-flight emissions measurements for a biojet fuel.

The program will also test blends of Green Jet Fuel at higher ratios than previous demonstration flights, which have been conducted using a 50/50 ratio of biofuel and jet fuel produced from petroleum. Previous evaluations of Green Jet Fuel have found a 60-85 percent reduction in greenhouse gas emissions relative to petroleum-based fuels.

The test flight program will utilize the unique research aircraft of the NRC Flight Research Laboratories, a modified Falcon 20 twin-engine jet that will test the fuel and a T-33 jet equipped to measure in-flight emissions while flying in formation.

The Resonance crop used for the biojet fuel was grown in Kincaid, Saskatchewan in the summer of 2011 and is being commercially contracted on a significant number of acres in western Canada for the 2012 crop year. Resonance has all the features necessary to make it a sustainable energy feedstock crop: a non-food industrial oilseed uniquely suited to production in semi-arid areas unsuitable for food oilseed production, excellent agronomic characteristics, good biotic and abiotic stress resistance, and reduced overall crop input requirements.

"As the first comprehensive testing program in the world using Resonance Energy Feedstock, Agrisoma is excited to be partnering with NRC and Honeywell UOP," said Steven Fabijanski, President and CEO of Agrisoma. "Resonance has been developed in Canada and our test flight program with NRC completes the value chain validation as well as providing comprehensive data demonstrating the reduced carbon footprint of biojet fuels compared to traditional fossil fuels."

"We are thrilled that Agrisoma is leading innovation in biofuels, and specifically in biojet fuel," commented Hugh Notman, President and CEO of Calyx. "Agrisoma is now positioned to further demonstrate the far-reaching value its proprietary oilseeds provide. Partnerships such as this will serve to accelerate the widespread adoption of Resonance carinata at every level."

"We are pleased to partner with Agrisoma on the first-ever flight to conduct airborne emissions testing - an effort that will demonstrate how Honeywell Green Jet Fuel can help reduce aviation emissions, while meeting flight specifications," said Jim Rekoske, vice president and general manager of Renewable Energy and Chemicals for Honeywell UOP. "Honeywell Green Jet Fuel has been used successfully in more than a dozen commercial and military test flights and we believe this momentous flight will continue demonstrating its viability as a sustainable fuel option."

Funding from Sustainable Development Technology Canada ("SDTC") supports the development of high-yielding oilseed crops engineered for the production of oils to be used in the manufacture of biofuels and products previously derived from petroleum based supplies. These new high-performance oilseeds will combine traits for oil chemistry and sustainable production methods which will result in a new bioenergy crop that will contribute to energy and rural economies, as well as providing environmental benefits in greenhouse gas emissions, soil and water use.

"This project shows next-generation biofuels at their best: combining qualities that make the most economic sense with those that reduce emissions," said Vicky Sharpe, President and CEO of SDTC. "Seeing these fuels in use is an important milestone - we congratulate Agrisoma and its partners."
