    Journal: Toxins (Basel); 2017 Jul 09; 9(7):. PubMed ID: 28698485.
    Abstract:
    There are a total of 30 strains including 27 strains of Aspergillus niger intended used in Chinese food industry, two strains used as control and one strain isolated from corn for fumonisin (FB) production on 3 media. It was found that FB₂ production by A. niger was function-dependent and highly related to culture media, as well as incubation time. All strains studied were unable to produce FB₁ and FB₃. Almost all strains were found to produce FB₂ on corn, rice and wheat bran. Based on their intended use in the food industry, the higher level of FB₂ producers were strains used for saccharifying enzyme (n = 13) production, followed by organic acid (n = 6), tannase (n = 7) and β-galactosidase (n = 1) production, with the FB₂ mean level of 3553-10,270 μg/kg, 1059-12,036 μg/kg, 3-7 μg/kg and 2-4 μg/kg on corn, 5455-9241 μg/kg, 559-2190 μg/kg, 4-9 μg/kg and 6-10 μg/kg on rice, 5959-7709 μg/kg, 9491-17,339 μg/kg, 8-14 μg/kg and 120-222 μg/kg on wheat bran, respectively. Comparatively, strains of Fusarium verticillioide were capable of producing fumonins simultaneously with broader spectrum including FB₁, FB₂ and FB₃, but at a much lower level. In conclusion, it is necessary to evaluate FB₂ production by A. niger before intended use in the food processing industry.
