| enhancing inulinase yield by irradiation mutation associated with optimization of culture conditions. | a new inulinase-producing strain was isolated from rhizosphere soils of jerusalem artichoke collected from shihezi (xinjiang, china) using jerusalem artichoke power (jap) as sole carbon source. it was identified as an aspergillus niger strain by analysis of 16s rrna. to improve inulinase production, this fungus was subjected to mutagenesis induced by (60)co γ-irradiation. a genetically stable mutant (designated e12) was obtained and it showed 2.7-fold higher inulinase activity (128 u/ml) than th ... | 2017 | 26413078 |
