Fungal spoilage is an important issue for the food industry, leading to food sensory defects, food waste, economic losses and public health concern through the production of mycotoxins. Concomitantly, the search for safer natural products has gained importance since consumers began to look for less processed and chemically treated foods. In this context, the aim of this study was to evaluate the antifungal and antimycotoxigenic effect of seven strains of Lactobacillus plantarum. Lactic acid bacteria (LAB) were grown on Man Rogosa Sharpe (MRS) broth at 37 °C in anaerobic conditions. After that, the cell-free supernatant (CFS) were recovered to determine its antifungal activity by halo diffusion agar test. In addition, minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) was determined for each L. plantarum CFS by 96-well microplates method. Additionally, CFS was used as a natural biocontrol agent on corn kernels and corn ears contaminated with Aspergillus flavus and Fusarium verticillioides, respectively. The L. plantarum CECT 749 CFS showed the highest antifungal effect against all essayed strains. Moreover, the employment of this CFS in food reduced the mycotoxin production at a percentage ranging from 73.7 to 99.7%. These results suggest that the L. plantarum CECT 749 CFS could be promising for the biocontrol of corn.

“…Some bacterial metabolites that suppress mycelial growth of fungi also interfere with fungal spore germination (Li et al ., ; Le Lay et al ., ). For collimomycin, such an effect has not yet been reported.…”

“…Fungal spore germination can also be inhibited by non‐self‐produced compounds, such as certain synthetic fungicides and bacterial metabolites. Some of these compounds impact not only spore germination but also mycelial growth, although not necessarily to the same extent (Siegel, ; Goettel et al ., ; Slawecki et al ., ; Reddy, ; Li et al ., ; Le Lay et al ., ; Leyva Salas et al ., ). Bacterially produced inhibitors of fungal spore germination can shape the outcome of interactions between fungi and plants, animals or humans, and thus may have practical relevance for managing fungi that are pathogenic to such hosts (Fisher et al ., ).…”

“…Bacterially produced inhibitors of fungal spore germination can shape the outcome of interactions between fungi and plants, animals or humans, and thus may have practical relevance for managing fungi that are pathogenic to such hosts (Fisher et al ., ). Mechanisms behind the observed bacterially induced arrest of fungal spore germination are not always known (Li et al ., ; Nogueira et al ., ) but include the bacterial synthesis of compounds with antagonistic activity, such as organic acids (Le Lay et al ., ) and cyclic lipopeptides (Chitarra et al ., ; Gong et al ., ), or metabolites that confer a competitive advantage, such as siderophores (Kousser et al ., ).…”

Collimonas fungivorans Ter331 (CfTer331) is a soil bacterium that produces collimomycin, a secondary metabolite that inhibits the vegetative growth of fungi.Here we show that CfTer331 can also interfere with fungal spore germination and that collimomycin biosynthesis is required for this activity. More specifically, in co-cultures of Aspergillus niger N402 (AnN402) conidiospores with CfTer331, the rate of transition from the isotropic to polarized stage of the germination process was reduced and the relatively few AnN402 conidiospores that completed the germination process were less likely to survive than those that were arrested in the isotropic phase. By contrast, a collimomycindeficient mutant of CfTer331 had no effect on germination: in its presence, as in the absence or delayed presence of CfTer331, unhindered germination of conidiospores allowed rapid establishment of AnN402 mycelium and the subsequent acidification of the culture medium to the detriment of any bacteria present. However, when challenged early enough with CfTer331, the collimomycin-dependent arrest of the AnN402 germination process enabled CfTer331 to prevent AnN402 from forming mycelia and to gain dominance in the culture. We propose that the collimomycin-dependent arrest of spore germination represents an early intervention strategy used by CfTer331 to mitigate niche construction by fungi in nature.
