Diversity and networking of uni-cyanobacterial cultures and associated heterotrophic bacteria from the benthic microbial mat of a desert hydrothermal spring.

ABSTRACT: Thermal springs harbour microorganisms, often dominated by cyanobacteria, which form biofilms and microbial mats. These phototrophic organisms release organic exudates into their immediate surroundings, attracting heterotrophic bacteria that contribute to the diversity and functioning of these ecosystems. In this study, the microbial mats from a hydrothermal pool in the Ksar Ghilane oasis in the Grand Erg Oriental of the Desert Tunisia were collected to obtain cyanobacterial cultures formed by single cyanobacterial species. High-throughput analysis showed that while the microbial mat hosted diverse cyanobacteria, laboratory cultures selectively enriched cyanobacteria from the Leptolyngbya, Nodosilinea, and Arthronema. Per each of these genera, multiple non-axenic uni-cyanobacterial culture
