Table 1.

Bacterial isolates from C. velia CCAP 1602/1. Strains used for headspace analysis are indicated in bold characters. The abundance of the bacteria in the phycosphere was calculated from the coverage information (= genome equivalents) of the metagenome assembled genomes (MAGs). For a more complete description see Table S1. A, Alphaproteobacteria; G, Gammaproteobacteria; F, Flavobacteriia, n.d., not determined.
