Itaconic acid production from xylose in repeated-batch and continuous bioreactors

Itaconic acid production by immobilized Aspergillus terreus with varied metal additions

“…Figure 3 also illustrates the smallest difference obtained with immobilized mycelium between the first and fourth 14-day batch end-product concentration of all experiments, suggesting that the best production stability was obtained with about 25% initial glucose, 3 g/1 of magnesium sulphate, 19.6 mg/1 of copper sulphate and 6.5 g/1 of calcium chloride. Unlike the earlier resuits obtained with xylose (Kautola 1990a), the first Fig. 3.…”

“…The optimization of nutrients and of the production conditions has been studied conventionally (Horitsu et al 1985), and by using a statistical experimental design and empiric modelling (Kautola et al 1987, 1989, Kautola 1990a). Batti and Schweiger (1963), Larsen and Hovden (1956), and Lockwood and Reeves (1945) have examined the effect of different metal ions on itaconic acid production by free Aspergiilus terreus.…”

“…A UV detector (Knauer Variable Wavelength Monitor, Wissenschaftliche Geriitebau Dr. Ing. H. Knauer, Berlin, FRG) was used at 210 nm(Kautola 1990a).…”

Saccharification of Lignocellulosic Materials by Cellulolytic and Xylanolytic <i>Paenibacillus illioisensis </i>CX11

“…In recent years, considerable attention has been focused on the enzymatic degradation of cellulose and hemicellulose as an attractive approach to hydrolyzing lignocellulosic materials [14,15]. The fermentation of lignocellulosic sugars has been used to produce highly valued compounds and products [16][17][18][19][20]. This process consists of two major steps, of which the first includes converting the cellulose and hemicellulose in the lignocellulosic materials into their respective fermentable sugars, and the second involves fermenting the released sugars into the targeted compounds.…”

“…The fermentable building block sugars from lignocellulosic materials can be converted into a variety of chemicals, such as acetic acid, succinic acid and itaconic acid, all of which can be used in numerous industries, such as the food, chemical and pharmaceutical industries [16][17][18][19][20]. Thus, the full utilization of lignocellulosic materials could put multiple industries that rely on chemicals for production on a path to sustainable development.…”
