“…Conventionally, medium-chain α, ω-DCAs are produced from petrochemical feedstocks or fatty acids by chemical processes which require high temperature and pressure, strong acids (H 2 SO 4 , HNO 3 ), or toxic oxidants (ozone). The chemical synthesis methods of medium-chain α, ω-DCAs are harmful to our environment and cause serious ecological problems ( Zhang et al, 2009 ; Köckritz and Martin, 2011 ). Thereby, it is very necessary to develop greener and sustainable processes to replace the present chemical processes, and more and more attention has been paid toward microbial production of medium-chain α, ω-DCAs via metabolic engineering and synthetic biology ( Biermann et al, 2011 ; Seo et al, 2015 ).…”

Medium-chain (C8–C14) α, ω-dicarboxylic acids (α, ω-DCAs), which have numerous applications as raw materials for producing various commodities and polymers in chemical industry, are mainly produced from chemical or microbial conversion of petroleum-derived alkanes or plant-derived fatty acids at present. Recently, significant attention has been gained to microbial production of medium-chain α, ω-DCAs from simple renewable sugars. Here, we designed and created a synthetic omega oxidation pathway in Saccharomyces cerevisiae to produce C10 and C12 α, ω-DCAs from renewable sugars and fatty acids by introducing a heterogeneous cytochrome P450 CYP94C1 and cytochrome reductase ATR1. Furthermore, the deletion of fatty acyl-CoA synthetase genes FAA1 and FAA4 increased the production of medium-chain α, ω-DCAs from 4.690 ± 0.088 mg/L to 12.177 ± 0.420 mg/L and enabled the production of C14 and C16 α, ω-DCAs at low percentage. But blocking β-oxidation pathway by deleting fatty-acyl coenzyme A oxidase gene POX1 and overexpressing different thioesterase genes had no significant impact on the production and the composition of α, ω-dicarboxylic acids. Overall, our study indicated the potential of microbial production of medium-chain α, ω-DCAs from renewable feedstocks using engineered yeast.

Wastewater treatment is in a dilemma: more energy and efforts have to be put forth to obtain an effluent with better quality, while a significant amount of sludge is generated and the treatment or disposal expenses are high. Even if the sludge is disposed of properly, the components can be released and pollute the environment again. Therefore, conversion and recovery of the contaminants to resources is the way out of the dilemma. An ion exchange membrane (IEM) is a special type of membrane, which allows charged solutes to pass through it while retaining uncharged components. Attributed to this character, IEMs are taking more important roles in separation and conversion processes recently. They act as key elements in many resource recovery systems, such as in separation and concentration, salt valorization, energy conversion, and even in microbial systems. This review summarizes the important processes for waste conversion and resource recovery from wastewaters by using IEMs. Drawbacks and perspectives are summarized in view of the development of the processes and the membranes.

“…To overcome this, processes are conducted at elevated temperatures [179], coupled with electrodeionization in which the presence of ion-exchange resin in the diluate compartment effectively decreases the stack electrical resistance [185], or process solutions are pre-concentrated by ED [135]. BMED conducted in mixed water-alcohol mixtures (so-called two-phase bipolar membrane electrodialysis, TPBMED) allowed for production of some acids: salicylic [186], sebacic [187], and long-chain linear acids of formula C n H 2n+1 COOH, with n = 2 -7 [188] and n = 7 -15 [189].…”

Abstract:The applicability of ion-exchange membranes (IEMs) in chemical synthesis was discussed based on the existing literature. At first, a brief description of properties and structures of commercially available ion-exchange membranes was provided. Then, the IEM-based synthesis methods reported in the literature were summarized, and areas of their application were discussed. The methods in question, namely: membrane electrolysis, electro-electrodialysis, electrodialysis metathesis, ionsubstitution electrodialysis and electrodialysis with bipolar membrane, were found to be applicable for a number of organic and inorganic syntheses and acid/base production or recovery processes, which can be conducted in aqueous and non-aqueous solvents. The number and the quality of the scientific reports found indicate a great potential for IEMs in chemical synthesis.
