Summary: | Fructooligosaccharides (FOS) are fructose-based oligosaccharides employed as additives to improve the food’s nutritional and technological properties. The rhizosphere of plants that accumulate fructopolysaccharides as inulin has been revealed as a source of filamentous fungi. These fungi can produce FOS either by inulin hydrolysis or by biosynthesis from sucrose, including unusual FOS with enhanced prebiotic properties. Here, we investigated the ability of
Fusarium solani
and
Neocosmospora vasinfecta
to produce FOS from different carbon sources.
Fusarium solani
and
N. vasinfecta
grew preferentially in inulin instead of sucrose, resulting in the FOS production as the result of endo-inulinase activities.
N. vasinfecta
was also able to produce the FOS 1-kestose and 6-kestose from sucrose, indicating transfructosylating activity, absent in
F. solani
. Moreover, the results showed how these carbon sources affected fungal cell wall composition and the expression of genes encoding for β-1,3-glucan synthase and chitin synthase. Inulin and fructose promoted changes in fungal macroscopic characteristics partially explained by alterations in cell wall composition. However, these alterations were not directly correlated with the expression of genes related to cell wall synthesis. Altogether, the results pointed to the potential of both
F. solani
and
N. vasinfecta
to produce FOS at specific profiles. |
