Under the program DEINOL, research teams were able to isolate and optimize a strain of bacteria “Deinococcus” capable of producing ethanol from biomass industrial wheat-based plant.

Issues of bioethanol are double today. First to produce biomass for not choosing between fuel or food. On the other hand produce 2nd generation bioethanol cost in a price increase of nearly 20%.

With an alcohol by volume of more than 3% DEINOL exceeds the threshold set by the milestone that aims to end the proof of concept. Indeed, the major industrial interest DEINOL solution lies in the ability of bacteria to degrade waste deinococci green complex into simple sugars and then converting them into ethanol, all in a single operation and without additives (such as enzymes, yeasts , antibiotics or antiseptics).

This success has led to progress in the payment of the third tranche of funding for the project OSEO DEINOL in ISI Program (Industrial Strategic Innovation), 1.15 million euros paid to the company Deinove. In total, the project has received $ 4.5 million in aid on the overall amount of € 8.9 million granted by OSEO.

While bioethanol production is currently limited to food biomass and uses old methods involving multiple steps and fermentation with yeast, the process “all in one” plant-based bacterial “Deinococcus” paves the way for the exploitation of non-food biomass (waste of the agricultural, plant biomass …) and processes more efficient, cleaner and less expensive.

“Beyond the funding that we provide, this result confirms the value of our technology to convert biomass into energy and industrial products. This is a world first technology which our teams and partners can boast the bacterium Deinococcus we optimized proved not only capable of degrading 80% of plant biomass but also produce industrial quantities bioethanol in line with our ambitions, “said Jacques Biton, CEO of Deinove.

He added: “We are entering a new phase, both confident in our ability to achieve the required performance for the final phase of industrialization DEINOL, and in the diverse field of applications of our micro-factories bacteria. ‘

“The chain of bioethanol is resolutely turned towards the second generation but is still waiting for its standard production,” noted Philippe Pouletty, Co-founder and Chairman of the Board of Directors Deinove. “The results show that DEINOL Deinove, and with him his TEREOS industrial partner, are at the forefront of the global race for standard and innovative process that could offer tomorrow to France the opportunity to strengthen its position in this key market for the future.’

Following this announcement, the price of the biotechnology company Deinove has soared (56.79%), from 8.10 euros to 12.70 euros the day before yesterday closing.

DEINOL, a technological breakthrough

Dramatically improving the economic and ecological performance of their facilities, the solution should provide DEINOL industrial chain of cellulosic bioethanol many competitive advantages:

A stable and reproducible process: once in the fermenter, the bacteria retain their properties because their genome remains stable because of their intrinsic property but also through DEINOVE approach which aims to guide nature rather than change it. With a great strength, they also tolerate physical and chemical stress they may encounter during the industrial process.

A high temperature process: the bacterial strain is capable of transforming biomass between 40 and 60°C, temperatures inaccessible to current processes (working at 35°C and require cooling, high-cost reactors and prevent microbial contamination that occur at these temperatures using antibiotics).

An all-in-one strain Deinococcus optimized is multifunctional, providing successively 1 / degradation of the various components rich in sugars and plant biomass carbon and 2 / alcoholic fermentation, without the help of additives.

An open solution: Beyond starch, bacteria bacterium Deinococcus DEINOVE are currently able to digest cellulose and hemicellulose, paving the way for the widespread use of non-food plant biomass.

Implementation simple and rational: the method can be implemented on existing industrial plants without major new investment.
