“The petrochemical industry is looking for a cost-efficient alternative to produce this valuable chemical and we are thrilled that Verdezyne’s platform is demonstrating considerable promise for commercialization of bio-based adipic acid,” says Stephen Picataggio, Ph.D., Chief Scientific Officer, Verdezyne.
“Our estimates indicate at least a 20% cost of manufacturing advantage for bio-based adipic acid depending on the feedstock selected,” stated E. William Radany, Ph.D., President and Chief Executive Officer, Verdezyne. “Rising consumer interest in bio-based products combined with a sustainable cost advantage makes Verdezyne’s process a compelling proposition for future production.”
is the main feedstock for the production of adipic acid
The global adipic acid market was approximately $4.9 billion in 2009 with its two major applications being polyamides and polyurethanes. is an important engineering resin for well-established markets like automotive, footwear, and construction and is used in everyday products such as carpets, coatings, furniture, bedding and automobile parts.
This is Verdezyne’s first major milestone towards demonstrating an entirely feedstock flexible fermentation process for the production of bio-based . The benefit of a feedstock flexible process is the ability to maintain a sustainable cost advantage regardless of future energy volatility. In addition to cost advantages, Verdezyne’s fermentation process will reduce greenhouse gas emissions compared to the traditional petrochemical production of adipic acid.

Paper: Bio-based adipic acid from renewable fats and …
Fatty acids shorter than C16 have substantial industrial uses. Lauric acid, the dominating fatty acid in palm kernel oil and coconut oil is, as mentioned earlier, an important feedstock for the detergent industry. However, shorter chain fatty acids like caprylic acid (8:0) and capric acid currently have no commercially viable plant source. These fatty acids are fractionated out from palm kernel and coconut fats and used mainly in the cosmetic industry as caproyl/capric TAGs. For the chemical industry, the same fatty acids are used in organic synthesis of a multitude of compounds and are mostly made from fossil sources via oxidation of the corresponding aldehyde. An oil crop producing high amounts of caprylic or capric acid in its oil would be an economic viable alternative to the organic chemical synthesis.
alternative feedstock for the production of adipic acid
In conclusion, traditional plant breeding methods and genetic engineering have shown that the percentage of any of the five the common fatty acids can be increased substantially. Oleic acid levels of over 85% can be achieved in oil crops without affecting oil yield. Further increase in oleic acid is probably possible by silencing enzyme activities responsible for the channelling of PUFA from PC, their site of synthesis, to the oil. Levels of linoleic acids can reach 90% in natural safflower varieties and ALA levels of up to 74% have been achieved in GM somatic soybean embryos. With respect to saturates, up to 77% palmitic acid has been achieved in cottonseed, but enhancement of stearic acid has been less successful for reasons mentioned above, with a maximum of about 40% being achieved in transgenic plants. This suggests some biological or agronomic limitations with respect to stearic acid accumulation. A more viable strategy to obtain high levels of stearic acid is probably through complete hydrogenation of very high oleic oils, a relatively cheap industrial process.

In order to make plant oils more competitive in the chemical industry, in planta optimisation of their composition will be necessary. For certain oil qualities and in certain oil crops, this can be done using traditional mutation breeding technologies. However, in most cases it requires the use of genetic engineering. The prime goal of such genetic engineering is to obtain as high proportion as possible of the desired fatty acid in the oil. This fatty acid could be a fatty acid that already exists in the oil or it might be a fatty acid that is novel for the species. In the first section of this review, we will give examples of what already has been achieved towards this goal and point out bottlenecks experienced as well as possible routes to overcome these bottlenecks.
17 Consider the synthesis of adipic acid ..
Since the advent of plant molecular biology much progress has been made in unravelling the enzymatic pathways of fatty acid and oil synthesis in plants, and in elucidating the genes encoding the key enzymes in several oil plant species. Early successes in modifying the relative proportions of the main common fatty acids have now been surpassed by the engineering of production of unusual fatty acids, including examples of the introduction of complex multistep biosynthetic pathways. These advances have so far resulted in relatively small concentrations of unusual fatty acids, which although suitable for some niche food and industrial applications, fall short of the high purity required for cost-effective industrial utilisation on a larger scale. With appreciation of the need to exclude unusual fatty acids from cellular membranes and an increasing knowledge of how wild plants achieve this through enzyme specialisation, we are now entering a period where metabolic engineering research can be anticipated to provide the solutions to assembly of high purity unusual fatty acids in oil crops. Additionally, current advances in engineering synthesis of wax esters as alternatives to triglycerides in seed storage lipids show promise of providing a simplified approach to accumulation of unusual fatty acids, in this case concomitantly with production of industrially useful fatty alcohols.
