“…The Aspergillus population consisted exclusively of A. niger and A. tubingensis, with the former being the dominant. Studies worldwide have identified section Nigri as the Aspergillus group responsible for OTA production, with A. carbonarius considered the main contamination source compared with other biseriate species of the A. niger aggregate (Garcia-Cela et al, 2014;Susca et al, 2014). In our study in vivo OTA production was evident in 8.4% and 14.3% of the A. niger and A. tubingensis isolates, respectively.…”

“…Considering the Aspergillus species composition of pomegranates, there is a strong indication of low risk for OTA contamination. Although A. niger is not considered a key player in OTA contamination, numerous reports from different commodities confirm its status as an important fumonisin producer (Frisvad et al, 2011;Perrone et al, 2013;Susca et al, 2014;Varga et al, 2010). Almost 38% of the A. niger isolates produced FB 2 in vitro, but in fruit inoculations only 20% of A. niger population produce FB 2 .…”

“…Black aspergilli reported to produce OTA include Aspergillus carbonarius, Aspergillus ochraceus, Aspergillus japonicus, Aspergillus aculeatus and species within the A. niger aggregate (A. niger, Aspergillus tubingensis). Apart from OTA, it was recently shown that strains of black aspergilli (A. niger and Aspergillus welwitchiae) possess putative fumonisin gene clusters and are able to produce fumonisins (B 2 and B 4 ) (Frisvad et al, 2011;Mogensen et al, 2010;Susca et al, 2014). Fumonisins are mainly associated with seed rots in cereals and maize caused by several Fusarium species and considered to be responsible for harmful effects on the health of humans or animals (Desjardins, 2006).…”

“…Most of them presented a truncated version of the OTA biosynthetic cluster, that resulted in the loss of their ability to produce the toxin. However, several authors have reported that A. welwitschiae and mainly A. niger are important FB 2 producers in maize [46,47]. Therefore, the presence of A. niger aggregate species discovered in the present work might be contributing to the FB 2 levels detected in corn samples.…”

A Comprehensive Study on the Occurrence of Mycotoxins and Their Producing Fungi during the Maize Production Cycle in Spain

Mycotoxin contamination is one of the main problems affecting corn production, due to its significant risk to human and animal health. The Fusarium and Aspergillus species are the main producers of mycotoxins in maize, infecting both pre-harvest and during storage. In this work, we evaluated the presence of mycotoxins and their producing species along maize production cycles in three different stages (anthesis, harvest, and storage) during three consecutive seasons (2016–2018). Fungal occurrences were studied using species-specific PCR protocols, whereas mycotoxin levels were determined by LC-MS/MS. Fumonisin-producing Fusarium species (F. verticillioides and F. proliferatum), as well as the aflatoxin producer Aspergillus flavus, were the most predominant species at all stages; although, during some seasons, the presence of F. graminearum and A. niger aggregate species were also identified. Contrastingly, fumonisins were the only mycotoxins detected and levels were always under legal regulations. The results presented here demonstrate that even when fungal contamination occurs at the early stages of the maize production cycle, the application of good agricultural and storage practices might be crucial to ensure mycotoxin-free grains.

“…About 77%, 77%, 50%, 76% and 72% strains of A. niger isolated from grape, grape raisin, grape mash, coffee and maize kernels, respectively, are capable of producing FB 2 [ 9 , 10 , 11 , 12 , 13 ]. Besides, 42% strains of Aspergillus section Nigri isolated from corn also shown the capability of FB 2 production [ 14 ]. A. niger is widely used in production of some foods and food additives and it has been granted as a “Generally Regarded As Safe” by US Food and Drug Administration in 1987.…”

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.
