“…This is in good agreement with the model results shown in Table 1, projecting the maximal IA titer as 28.1 g/L. In the literature, IA titers with A. terreus 1960 strain ranging between 40 and 110 g/L were reported by Karaffa et al [17] using glucose, while Kocabas et al [27] obtained 18 g/L from glucose containing media tested in biorefinery concept. Accordingly, though the maximum IA titer is a function of many factors that are different from one study to another, our present results are in the same order of magnitude of the already published data and thus, comparable with those.…”

In this work, itaconic acid (IA) was produced biotechnologically by Aspergillus terreus fungal strain from glucose. The performance of the batch fermentation was kinetically assessed and the maximal IA production potential, maximal production rate and lag-phase time were determined as 28.1 g/L, 3.83 g/L day and 1.52 days, respectively. In addition, the bioprocess was evaluated based on the most frequently used parameters, in particular IA titer (26.3 g/L), yield (0.22 g/g substrate) and productivity (0.1 g/L h), which were comparable to the already published literature. Furthermore, an on-line monitoring system was installed to the fermenter in order to measure the CO 2 content of the bioreactor off-gas. Actually, it was indicated by the results that the CO 2 production could have a linear-like relationship with the quantity of fungal biomass. Hence, the data collected in such a way may have the potential to establish an alternative methodology for the monitoring of biomass growth in the course of the biological transformation taking place.

“…Fermentation of other sugars to itaconic acid results in low yields: 18%, 31%, and less than 1% using arabinose, xylose, and lactose, respectively [399]. Fermentation times for itaconic acid generation range from 2 to 14 days, with an optimum of 7 days at around 37 °C [400–402]. Intensive research to reduce the production cost of itaconic acid is undergoing.…”

The demand for fossil derivate fuels and chemicals has increased, augmenting concerns on climate change, global economic stability, and sustainability on fossil resources. Therefore, the production of fuels and chemicals from alternative and renewable resources has attracted considerable and growing attention. Ethanol is a promising biofuel that can reduce the consumption of gasoline in the transportation sector and related greenhouse gas (GHG) emissions. Lignocellulosic biomass is a promising feedstock to produce bioethanol (cellulosic ethanol) because of its abundance and low cost. Since the conversion of lignocellulose to ethanol is complex and expensive, the cellulosic ethanol price cannot compete with those of the fossil derivate fuels. A promising strategy to lower the production cost of cellulosic ethanol is developing a biorefinery which produces ethanol and other high-value chemicals from lignocellulose. The selection of such chemicals is difficult because there are hundreds of products that can be produced from lignocellulose. Multiple reviews and reports have described a small group of lignocellulose derivate compounds that have the potential to be commercialized. Some of these products are in the bench scale and require extensive research and time before they can be industrially produced. This review examines chemicals and materials with a Technology Readiness Level (TRL) of at least 8, which have reached a commercial scale and could be shortly or immediately integrated into a cellulosic ethanol process.

“…Corn cob, a lignocellulosic residue, was used in a twostep process: first, xylanase was produced by A. terreus, which was further used on the second step of the process concerning the hydrolysis of the lignocellulosic feedstock (with addition of commercial xylanase) for obtaining fermentable sugars for IA production, also by A. terreus (about 8 g/L IA) (Kocabas et al 2014). A different lignocellulosic material, beech wood hydrolysate, was used for IA production and about 13 g/L IA was produced by A. terreus in solid-state reactor after the removal of phenolic components with anion and cation exchangers (Sieker et al 2012).…”

World market and biotechnological production of itaconic acid

The itaconic acid (IA) world market is expected to exceed 216 million of dollars by 2020 as a result of an increasing demand for bio-based chemicals. The potential of this organic acid produced by fermentation mainly with filamentous fungi relies on the vast industrial applications of polymers derived from it. The applications may be as a superabsorbent polymer for personal care or agriculture, unsaturated polyester resin for the transportation industry, poly(methyl methacrylate) for electronic devices, among many others. However, the existence of other substitutes and the high production cost limit the current IA market. IA manufacturing is done mainly in China and other Asia-Pacific countries. Higher economic feasibility and production worldwide may be achieved with the use of low-cost feedstock of local origin and with the development of applications targeted to specific local markets. Moreover, research on the biological pathway for IA synthesis and the effect of medium composition are important for amplifying the knowledge about the production of that biochemical with great market potential.
