There are a total of 30 strains including 27 strains of 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 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 ( = 13) production, followed by organic acid ( = 6), tannase ( = 7) and β-galactosidase ( = 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 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 before intended use in the food processing industry.
共有30株菌株,其中27株用于中国食品工业,2株用作对照,1株从玉米中分离出来,用于在3种培养基上生产伏马毒素(FB)。结果发现,[具体菌株名称未给出]产生FB₂的情况与培养基和培养时间有关,具有功能依赖性。所有研究的菌株均不能产生FB₁和FB₃。几乎所有菌株在玉米、大米和麦麸上都能产生FB₂。根据它们在食品工业中的预期用途,产生FB₂水平较高的菌株是用于生产糖化酶的菌株(n = 13),其次是生产有机酸的菌株(n = 6)、单宁酶的菌株(n = 7)和β-半乳糖苷酶的菌株(n = 1),在玉米上FB₂的平均水平分别为3553 - 10270μg/kg、1059 - 12036μg/kg、3 - 7μg/kg和2 - 4μg/kg,在大米上分别为5455 - 9241μg/kg、559 - 2190μg/kg、4 - 9μg/kg和6 - 10μg/kg,在麦麸上分别为5959 - 7709μg/kg、9491 - 17339μg/kg、8 - 14μg/kg和120 - 222μg/kg。相比之下,[具体菌株名称未给出]的菌株能够同时产生伏马毒素,谱带更宽,包括FB₁、FB₂和FB₃,但水平要低得多。总之,在将[具体菌株名称未给出]用于食品加工业之前,有必要评估其FB₂的产生情况。
