Fabricio Cassán, PhD, is a microbiologist and Principal Researcher at INIAB-CONICET and Associate Professor at UNRC. With nearly 30 years of expertise on Azospirillum and other plant growth-promoting rhizobacteria, he has authored over 100 scientific contributions and led several international collaborations. His research bridges both fundamental and applied studies, advancing the use of Azospirillum in sustainable agriculture. Luz de-Bashan Ph.D, is the Director of the Bashan Institute of Science in Alabama, and an Affiliate Professor in the Department of Entomology and Plant Pathology at Auburn University. Her research focuses on the interactions between Azospirillum and microalgae for biotechnological applications, the restoration of degraded soils with plant growth-promoting bacteria and native plants, and the development of bacterial inoculants. Florence Wisniewski-Dyé is professor of microbial ecology at University of Lyon 1, France. With 25 years of expertise on plant growth-promoting bacteria, she was one of the pioneers in conducting comparative and functional genomic studies on Azospirillum; she contributed to reveal the high genomic plasticity of this genus, a trait that was critical for adaptation and interaction with host plants.

Guillermo Maroniche holds a Ph.D. in Biological Sciences and is currently an Independent Researcher of CONICET at FCA-UNMdP, Balcarce, Argentina. His research focuses on the mechanisms regulating the interspecific interaction between members of the plant microbiome, such as Azospirillum and Pseudomonas, and their host, aiming in the long term at improving the efficacy of inoculants based on synthetic microbial communities.
