Utilization of cyanobacterial siderophore cyanochelin B by phylogenetically distant heterotrophs suggest its role in mediating microbial interactions

Berness Peter Falcao, José Alberto Martínez Yerena, Tomáš Galica, Jan Mareš, Clémentine Laffont, Lenka Štenclová, Surbhi Sharma, Jürgen Tomasch, Divya Aggarwal, Jan Masek, Petra Divoká, Kateřina Čapková, Tomáš Bešta, Vendula Krynická, Rolf Kümmerli, Pavel Hrouzek

The paper shows that cyanobacterial siderophore cyanochelin B is used by distant heterotrophs under iron limitation, supporting microbial interactions in soil crust ecosystems.

Cyanochelin B: A siderophore produced by cyanobacterium Leptolyngbya sp. NIES-3755 with photolytic properties that negate iron monopolization in the UV-light

Berness Peter Falcao, Viviana Di Matteo, Pavel Hrouzek, Lenka Štenclová, Petra Urajová, Jan Mareš, Jan Kuta, José Alberto Martínez Yerena, Eliška Zapomělová, Germana Esposito, Alfonso Mangoni, Valeria Costantino, Tomáš Galica

This paper characterizes cyanochelin B, a photolytic siderophore from cyanobacteria, showing it can both monopolize iron and release it under UV light, depending on environmental conditions.
