Coproduction of inulinase and invertase by in whey-based medium and evaluation of additional nutrients.

The purpose of this research was to evaluate the suitability of whey as an effective medium for the coproduction of inulinase and invertase by an oleaginous yeast and to investigate the effects of some additional carbon and nitrogen sources. The nutritional factors and composition of the medium have a great impact on the production pathways of microbial enzymes. To deepen the research, a Taguchi design was employed to quickly scan the best conditions.

Optimization of inulinase production using Jerusalem artichoke () as cheap substrate and comparison with pure chicory inulin.

Jerusalem artichoke (JA) is a nutritional vegetable for human diet depending on its natural structure, especially high inulin content and it is the second inulin source for commercial production in the world, after chicory. It was aimed to investigate the inulinase production capability of TS61 (GenBank accession: MN749818) using JA as an economical and effective substrate comparing with the pure chicory inulin and to optimize the fermentation using Taguchi design of experiment (DOE) in this study. Besides, the effects of sucrose on inulinase production either combined with JA or in its absence were also studied.

Deronectes taron sp. n. from the eastern Anatolian region of Turkey (Coleoptera, Dytiscidae, Hydroporinae).

Deronectes taron sp. n. from the Muş province in the eastern Anatolian region of Turkey is described and illustrated in detail.

Inulinase production by Geotrichum candidum OC-7 using migratory locusts as a new substrate and optimization process with Taguchi DOE.

Utilization of migratory locusts (Locusta migratoria) as a main substrate due to its high protein content for inulinase (2,1-β-d-fructan fructanohydrolase) production by Geotrichum candidum OC-7 was investigated in this study. To optimize fermentation conditions, four influential factors (locust powder (LP) concentration, sucrose concentration, pH and fermentation time) at three levels were investigated using Taguchi orthogonal array (OA) design of experiment (DOE). Inulinase yield obtained from the designed experiments with regard to Taguchi L9 OA was processed with Minitab 15 software at 'larger is better' as quality character.

Citric acid production from Aspergillus niger MT-4 using hydrolysate extract of the insect Locusta migratoria.

Citric acid (CA) is the most important organic acid used in the food and other industries. Locusta migratoria is an insect species, which has rich nutritional composition (especially protein) and cultivated in some countries. Therefore, the present study investigated the usability of hydrolysate extract of L.
