Proceedings / Indian Academy of Sciences, 1936 1. Highly active preparations of inulinase can be obtained from a species ofaspergillus which is grown on artichoke nutrient media. Comparative culture experiments have revealed that phosphates definitely stimulate the formation and enrich the inulinase content of the preparations. 2. The fungus preparation can be preserved for months in

Immobilization of inulinase for sucrose hydrolysis
Food Chemistry, 2005A commercial inulinase preparation immobilized on various supports was used for sucrose hydrolysis. Entrapment and encapsulation in Ca-alginate and entrapment in an alginate–silicate sol–gel matrix were evaluated. Best results were obtained with Ca-alginate beads.

Inulinase-expressing microorganisms and applications of inulinases
Applied Microbiology and Biotechnology, 2009In this review article, inulinase-expressing microorganisms and its potential applications in transformation of inulin into very-high-fructose syrup, bioethanol, and inulooligosaccharides are overviewed. In the past 10 years, many new inulinase producers have been obtained and many genes encoding inulinases from different microorganisms have been ...

Inulinase ofDebaryomyces cantarellii
Folia Microbiologica, 1982Debaryomyces cantarellii excretes into a buffered medium an inulinase of beta-fructofuranosidase type, its synthesis being induced by inulin. The enzyme has a pH optimum at 4 and its optimum temperature is 50 degrees C. Its Km for inulin is 15 mM.

[Screening strains producing inulinase and cloning of inulinase gene].
Wei sheng wu xue bao = Acta microbiologica Sinica, 2004A wild-type strain AF10 producing inulinase was screened from soil samples, the strain is identified to be a A. niger. A endoinulinase gene inuA1 from A. niger AF10 was wequenced and analyzed, after PCR amplification. The results shows inuA1 is 1551 bp in length without any intron and contains 4 potential N-glycosylation sites.

Biosynthesis of Inulinases by Bacillus Bacteria
Applied Biochemistry and Microbiology, 2002Biosynthesis of extracellular inulinase by bacteria Bacillus polymyxa 29, B. polymyxa 722, and B. subtilis 68 was studied. The optimal parameters for the producer growth were as follows: pH 7.0, 33-35 degrees C, the growth duration within 72 h. The presence of mineral reduced or of organic nitrogen was necessary for the enzyme biosynthesis.

Inulinase activity ofDebaromyces cantarellii
Folia Microbiologica, 1980Debaromyces cantarellii Capriotti contains an inulinase activity which is inducible by growth on inulin but not on other beta-fructosides. The induction is inhibited by glucose and fructose. The system is situated in the cell wall and can be best extracted with a 20 mM phosphate buffer at pH 8.5.

Trends in inulinase production – a review
Critical Reviews in Biotechnology, 2009This article highlights the research work carried out in the production of inulinases from various inulin substrates using strains of bacteria, yeast and fungi. Inulin is one of the numerous polysaccharides of plant origin that contains glucose or fructose. It is used as a substrate in industrial fermentation processes and in food industries due to its

Difructose anhydride-forming bacterial inulinase II and fructogenic fungal inulinase I
Applied Biochemistry and Biotechnology, 1996The reserve polymeric inulin from dahlia tuber (>12% or >60% yield, wet or dry basis, respectively) follows as an attractive source for both free fructose or difructofuranose anhydride (DFA III). Although DFA biological activity is not completely understood, there is interest in characterizing other DFA III-producers besides Arthrobacter ureafaciens ...

Inulinases are versatile enzymes that act on β-2, 1 linkage of fructopolymers, like inulin. Inulinases can be produced by plants and many microorganisms, and the latter are the best sources for inulinases production, as they are easy to be cultivated and produce high yields of enzymes. Crude inulinases obtained through fermentation are usually purified
