Abstract: Kelp canopy resilience is partly influenced by their microbial partners, yet the stability of these associations in biobank-stored germplasm is unknown. We investigated how storage duration and media composition drive changes in the microbiome of Macrocystis pyrifera gametophytes. Our data suggest a shift in microbiome composition, characterized by a decline in overall microbial biodiversity. Media type significantly modulated this effect, with L1 formulation better preserving a diverse community structure than F/2 formulation. Our work here indicates that biobanking practices inadvertently select for specific microbial consortia, with implications for the viability and physiological function of preserved kelp germplasm.
