Biological production of adipic acid is a promising alternative to the environmentally challenged petrochemical-based process currently used. Lignin is a promising feedstock for adipic acid production as it can be broken down into the aromatic intermediates that can be used to produce adipic acid. One common pathway for microbial production of adipic acid goes through a catechol intermediate to form muconic acid, which is then reduced to form adipic acid. To produce adipic acid in Escherichia coli, we utilize an enzyme cascade of catechol 1,2-dioxygenase (CatA) and enoate reductase (ER). Optimization of protein expression using synthetic biology allowed us to optimize adipic acid yield. Furthermore, we characterize our enzyme cascade by analyzing its metabolism of different substituted catechols available from lignin pyrolysis. We demonstrate production of substituted dicarboxylic acids that could be used in the production of nylon analogs with tunable properties. To quantify metabolism of ...
SUMMARY: β-Ketoadipate serves as a chemoattractant for Pseudomonas putida. The chemotactic response is inducible, and a regulatory mutant strain that forms the β-ketoadipate transport system at high levels exhibits a heightened chemotactic response to β-ketoadipate. Adipate and succinate, compounds that interact with the transport system, inhibit chemotaxis toward β-ketoadipate. Some, but not all, mutants that fail to respond chemotactically to β-ketoadipate lack the β-ketoadipate transport system. It thus appears that the transport of β-ketoadipate is associated with its function as a chemoattractant. It is likely that the metabolite attracts fluorescent Pseudomonas species to environments in which complex aromatic polymers undergo microbial dissimilation.
Press Release issued Apr 24, 2017: Adipic acid is one of the most commercially important type of aliphatic dicarboxylic acids, especially due to its significant usage as a feedstock for the production of industrial fibers. It is produced from the oxidation of a mixture of cyclohexanol and cyclohexanone with nitric acid. Alternatively, adipic acid can also be produced from butadiene carbonylation. There has been a significant demand for chemically resilient, strong and durable fibers for the manufacture of automotive parts. This has initiated a strong demand for adipic acid, since it is one of the key ingredients for the production of composite materials. The major consumption of adipic acid is as the feedstock for the production for nylon 6,6 resin and engineering fibers. The non-nylon applications of adipic acid include its usage in the manufacture of polyurethanes, plasticizers, food additives and pharmaceuticals.
Global Adipic Acid Market is expected to reach USD 7,240.8 million by 2020, according to a new study by Grand View Research, Inc. Growing demand for nylon resins and fiber from major end use industries such as automotive and electronics mainly in BRIC nations is expected to remain a key driving factor for the market over the next six years. However, volatility in raw material prices coupled with stringent regulations in Europe and North America on account of growing environmental concerns is expected to hinder the market growth over the forecast period. Development of bio-based adipic acid emerged as a new driving force for the global Adipic Acid market. Bio-based adipic acid is an environment friendly solution, and provides cost advantage over its synthetic counterpart. Rennovia has been one of the pioneers for bio-based adipic acid development, using glucose as feedstock via its proprietary chemical catalytic process technology. Nylon 6,6 both in its fiber and resin forms emerged as the ...

Earlier generation of Mater-Bi® are composed of starches derived from plants, mainly corn starch, and a fully biodegradable synthetic aliphatic-aromatic polyester called PBAT (polybutylene adipate co-terephthalate) trademarked under the name Origo-Bi. This biodegradable synthetic polyester technology made with combination of diacids (e.g. adipic acid and terephthalic acid) and diols (e.g. BDO), was acquired from Eastman, which was originally called Eastar-Bio, in 2004.. The blog is guessing that for the 4th generation Mater-Bi® line, instead of using petroleum-based monomers, adipic acid and BDO, adipic acid will be then be substituted by vegetable oil-based azelaic acid (the blog heard that this diacid is produced from rancidity of oleic acid) and Genomaticas biobased BDO. Substitution of the aromatic terephthalic acid with a biobased material will still take time..

Reitman and colleagues had a hunch that the genetic mutation seen in cancer might trigger a similar functional change to a closely related enzyme found in yeast and bacteria (homoisocitrate dehydrogenase), which would create the elusive 2-hydroxyadipate dehydrogenase necessary for "green" adipic acid production.. They were right. The functional mutation observed in cancer could be constructively applied to other closely related enzymes, creating a beneficial outcome - in this case the missing link that could enable adipic acid production from cheap sugars. The next step will be to scale up the overall adipic acid production process, which remains a considerable undertaking.. "Its exciting that sequencing cancer genomes can help us to discover new enzyme activities," Reitman said. "Even genetic changes that occur in only a few patients could reveal useful new enzyme functions that were not obvious before.". Yan, a professor in the Department of Pathology and senior author of the study, said the ...

The production of salt or cocrystalline forms is a common approach to alter the physicochemical properties of pharmaceutical compounds. The goal of this work was to evaluate the impact of anion choice (succinate, adipate, and sulfate) on the physicochemical characteristics of salbutamol forms. Novel crystals of salbutamol were produced by solvent evaporation: a cocrystal of salbutamol hemiadipate with adipic acid (salbutamol adipate, SA), salbutamol hemisuccinate tetramethanolate (SSU.MeOH), and its desolvated form (SSU). The crystalline materials obtained were characterized using thermal, X-ray, nuclear magnetic resonance, Fourier transform infrared spectroscopy, dynamic vapor sorption (DVS), and elemental analysis. The crystal forms of SA and SSU.MeOH were determined to be triclinic, (P?i), and monoclinic, (P21/n), respectively. DVS analysis confirmed that SSU and SA do not undergo hydration under increased relative humidity. Both thermal and elemental analyses confirmed the stoichiometry of ...
In a 103-week carcinogenicity study, the read-across substance DEHA was administered to F344 rats and B6C3F1 mice in the diet at levels of 12000 or 25000 ppm, equivalent to a daily intake of 600 or 1250 mg/kg of body weight in rats and 1715 or 3570 mg/kg of body weight in mice (conversion based on data from the WHO report (2004)). No test substance related tumors were found in the rat (no increased tumour incidences). In the (female) mice an increased number of hepatocellular carcinomas was found at both doses. Hepatocellular adenomas and carcinomas occured combined in high-dose mice of both sexes and in low-dose female mice at incidences that were dose-related and significantly higher than those in control mice. The association of liver tumours in male mice with the administration of DEHA was not considered to be conclusive because the increased number of liver tumours in males reflected only an increase in adenomas in the high-dose group and because the time to observation of tumours was not ...
