Calyx Operating Subsidiary Participates in Canada's First Bio-Fuel Powered Revenue Flight

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 17, 2012) - Calyx Bio-Ventures Inc. ("Calyx" or the "Company") (TSX VENTURE:CYX) is pleased to announce that the Company's operating subsidiary, Agrisoma Biosciences Inc. ("Agrisoma"), produced the carinata bio-fuel which was blended into the fuel used in Canada's first bio-fuel powered revenue flight, successfully conducted today by Porter Airlines.

In the successful conclusion to a test program that was launched in 2010, Porter Airlines flew one of its Bombardier Q400 turboprops from its base at Billy Bishop Toronto City Airport to Ottawa using a 50/50 blend of biofuel and Jet A1 fuel in one of its engines. The fuel was certified to the new American Society for Testing and Materials (ASTM) D7566/D1655 standard and the biofuel used was derived from the oilseed crops, Camelina sativa* (49 per cent) and Brassica carinata* (one per cent). The aircraft's other engine was powered by Jet A1 fuel. The flight included passengers making their way to Ottawa for business and pleasure, representatives from the biofuel test program's partnering organizations and media.

This is the final step in a two-year project whose key members are Targeted Growth, Bombardier Aerospace, Pratt and Whitney Canada, the manufacturer of the PW150A engines that power the Q400 aircraft, and Porter Airlines. Funding for the biofuel test program was provided by the key partners, as well as by Business-Led Networks of Centres of Excellence (BL-NCE) through the Green Aviation Research & Development Network (GARDN).

Additional support to the program was provided by Agrisoma Biosciences Inc., which grew the carinata and produced the carinata bio-oil; Sustainable Oils, which crushed the camelina to make the camelina bio-oil; Honeywell UOP, which converted the bio-oils into the bio-derived jet fuel to meet the D7566 standard; and SkyNRG who were responsible for logistics and blending meeting the D1655 specification.

"We are very pleased that Agrisoma was a participant in supplying bio-fuel refined from Agrisoma's proprietary carinata for this flight," commented Hugh Notman, President and Chief Executive Officer of Calyx. "We believe this demonstrates carinata's potential to produce a high quality fuel that performs well in a commercial setting."

On February 9, 2012, in preparation for Porter's revenue flight, Bombardier flew a Q400 turboprop test aircraft on the ASTM D7566/D1655 bio-derived jet fuel. This was the first such biofuel-powered test flight in Canada.
