Growth Condition | |
Strains | Aspergillus niger BO-1 |
Genotype | Wild type,producing oxalic acid as a by-product which causes problems with downstream processing of industrial enzymes. |
Culture medium | The Aspergillus strains were grown in a defined medium containing: 15g/L glucose monohydrate, 7.3g/L (NH4)2SO4, 1.5g/L KH2PO4, 1.0g/L MgSO4-7H2O, 1.0g/L NaCl, 0.1g/L CaCl2-2H2O, 0.5ml/L sb2121, 7.2mg/L ZnSO4-7H2O, 1.3mg/L CuSO4-5H2O, 0.3mg/L NiCl2-6H2O, and 6.9mg/L FeSO4-7H2O. |
Carbon source | Glucose |
Growth rate | 0.19/h |
Case-specific description | Metabolic fluxes in the central metabolism of A.niger BO-1 during batch cultivation (BAN26). |
Growth Condition | |
Strains | A.niger oah disruptant 4-1 |
Genotype | The oah gene encoding oxaloacetate hydrolase (EC 3.7.1.1) was disrupted in a glucoamylase-producing strain of A. niger and the resulting strain was incapable of producing oxalic acid. |
Culture medium | The Aspergillus strains were grown in a defined medium containing: 15g/L glucose monohydrate, 7.3g/L (NH4)2SO4, 1.5g/L KH2PO4, 1.0g/L MgSO4-7H2O, 1.0g/L NaCl, 0.1g/L CaCl2-2H2O, 0.5ml/L sb2121, 7.2mg/L ZnSO4-7H2O, 1.3mg/L CuSO4-5H2O, 0.3mg/L NiCl2-6H2O, and 6.9mg/L FeSO4-7H2O. |
