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. View Full-Text
