摘要: Summary Inulinases constitute an important class of enzymes for production fructose and fructooligosaccharides, which are extensively used in pharmaceutical food industry. The inulinases has been reported from various fungal, yeast bacterial strains. characterized until now show considerable variability with respect to biophysical biochemical characteristics. High temperature optimum thermostability two criteria determine the suitability these industrial applications. high strains Aspergillus spp. thermophilic bacteria have reported. Molecular cloning inulinase genes different sources revealed that beside conserved domains, endo- exo-acting motifs distinct classes enzymes. present article reviews some recent advances characterization microbes their possible
