This disclosure describes the microbial network and community assembly patterns of brown macro algae, e.g., Macrocystis pyrifera gametophyte germplasm, cultures used to cultivate an offshore farm and identify network features associated with increased biomass of mature sporophytes. Several network features, such as clustering coefficient and edge ratios, significantly vary with biomass outcomes; also, gametophytes that become low- or high biomass sporophytes have different hub taxa. This disclosure describes microbial community dynamics in M. pyrifera germplasm cultures and development of early life stage inoculants used on seaweed cultivars to increase biomass yield.
