Abstract
[Objective] The research aimed to explore the effects of different concentrations of Gibberellin on production of Gluconic acid by fermentation using Aspergillus niger.[Method] Unconverted sugar was analyzed by di-nitrosalicyclic acid method and Aspergillus niger liquor was analyzed by ultraviolet spectrophotometer.[Result] Different disposed groups accelerated the growth of Aspergillus niger.Five disposed groups with quality density of 0.05,0.10,0.50,1.00,1.50 mg/L were higher by 25.12%,35.39%,32.16%,0.44%,1.38% than empty groups.And the best quality density was 1.00 mg/L.Gibberellin accelerated the translation of Gluconic acid from glucose.The best quality density was also 1.00 mg/L.[Conclusion] The effects of definite concentrations of Gibberellin on growth of Aspergillus niger and its fermentation were obvious.
