Collection and media specifications for each microbial isolate associated with <i>Z</i>. <i>marina</i>.

Here we report the specifics of the culture media used to initially grow each isolate including the media recipe used, the salt source and amount, and the inclusion of dehydrated crushed seagrass and of various antibiotics. We also report the collection date of the initial inoculum, whether the inoculum if tissue (e.g. roots, rhizome, leaves) came from tissue washes, crushed tissue or whole tissue, whether the plated inoculum was associated with an individual Z. marina plant from a core or multiple Z. marina plants from a bag, and finally the DNA extraction kit used to extract DNA from each isolate.
