The Pfizer process involves submerged fermentation of free A. terreus cells in pretreated molasses with IA production of around a titer of 65 g/L and a yield of g/g was obtained. Succinic and fumaric acid were two of the major by-products. R.P. SinghEnhanced production of itaconic acid from corn starch and market refuse fruits by Author: Juliana C. da Cruz, Eliana F. Camporese Sérvulo, Aline M. de Castro. Itaconic acid is used as an intermediate in the production of polyacrylonitrile fibres and as a plasticiser in certain polymer products. In the conventional batch fermentation process the pH in the fermenter which tends towards lower values during the acid production, is . Itaconic acid (IA) can be used: • As a comonomer in the polymerization of polyacrylonitrile (PAN) to promote the thermo-oxidative stabilization of polymer. • In combination with acrylamide to form (poly[acrylamide-co-(itaconicacid)]) to synthesize biodegradable superabsorbent polymers. Aug 17, · The highest itaconic acid yield is obtained when glucose is used as the substrate, but glucose is too expensive to be used as a raw material for commercial production of itaconic acid. Therefore, other raw materials that are cheaper than glucose, such as starch, molasses, hydrolysates of corn syrup or wood, were also chevreschevalaosta.com: Xuenian Huang.
Dec 07, · Ustilago maydis produces itaconic acid via the unusual intermediate trans‐aconitate. Itaconate production from trans‐aconitate was not observed in Cultures were incubated for 48 h at 30°C and r.p.m.. Itaconic acid production in the supernatant was Cited by: Oct 10, · The present invention relates to the preparation of itaconic acid by fermentation, and, more especially, via microbial fermentation of particular nutrient media. 2. Description of the Prior Art. The production of organic acids by fermentation of sugars in the presence of a suitable microorganism is universally known to this art. int. j. agric. appl. sci. vol. 5, no.1, 8 citric acid production from sugarcane molasses by aspergillus niger under different fermentation conditions and substrate levelsAuthor: Umar Farooq, Faqir Muhammad Anjum, Tahir Zahoor, Zafar Hayat, Kashif Akram, Ejaz Ashraf. Jan 09, · Calam et al. published a method for producing itaconic acid using Aspergillus terreus in in Biochem. J., volume 33, pages T. Kobayashi and a colleague obtained Japanese patent in and in for the production of itaconic acid using Aspergillus itaconicus and Aspergillus terreus, with molasses used as the material to be.
An Escherichia coli system was engineered for the heterologous production of itaconic acid via the expression of cis-aconitate decarboxylase gene (cad), and then maximal itaconic acid levels produced by engineered E. coli were evaluated. Expression of cad in E. coli grown in Luria-Bertani (LB) medium without glucose in a test tube resulted in g/L itaconic acid production after 78 h at 20°C. May 19, · The family of Ustilaginaceae is known for their capability to naturally produce industrially valuable chemicals from different carbon sources. Recently, several Ustilaginaceae were reported to produce organic acids from glycerol, which is the main side stream in biodiesel production. In this study, we present Ustilago vetiveriae as new production organism for itaconate synthesis from chevreschevalaosta.com by: Itaconic acid (IA) is an unsaturated dicarbonic organic acid. It can easily be incorporated into polymers and may serve as a substitute for petrochemical-based acrylic or methacrylic acid. It is used at 1–5% as a comonomer in resins and also in the manufacture of synthetic fibres, Cited by: Dec 08, · Recently, itaconic acid (IA), an unsaturated C5-dicarboxylic acid, has attracted much attention as a biobased building block chemical. It is produced industrially (>80 g L−1) from glucose by fermentation with Aspergillus terreus. The titer is low compared with citric acid production (> g L−1). This review summarizes the latest progress on enhancing the yield and productivity of IA Cited by:
