With national interest in seaweed-based biofuels as a sustainable alternative to fossil fuels, there is a need for tools that produce high-yield seaweed cultivars and increase the efficiency of offshore farms. Several agricultural studies have demonstrated that the application of microbial inoculants at an early life stage can improve crop yield, and there is an opportunity to use similar techniques in seaweed aquaculture. However, there is a critical knowledge gap regarding host-microbiome associations of macroalgae gametophytes in germplasm cultures. Here, we investigate the microbial community of Macrocystis pyrifera gametophyte germplasm cultures that were used to cultivate an offshore farm in Santa Barbara, California and identify key taxa correlated with increased biomass of mature sporophytes. This work provides a valuable knowledge base for the development of microbial inoculants that produce high-biomass M. pyrifera cultivars to ultimately be used as biofuel feedstocks.
随着国家对以海藻为基础的生物燃料作为化石燃料的可持续替代品的关注，需要有能培育出高产海藻品种并提高近海养殖场效率的工具。多项农业研究表明，在生命早期阶段施用微生物接种剂可以提高作物产量，并且有机会在海藻养殖中使用类似技术。然而，关于种质培养中大型藻类配子体的宿主 - 微生物组关联存在关键的知识空白。在此，我们调查了用于在加利福尼亚州圣巴巴拉市培育近海养殖场的巨藻配子体种质培养物的微生物群落，并确定与成熟孢子体生物量增加相关的关键分类群。这项工作为开发能培育出高生物量巨藻品种以最终用作生物燃料原料的微生物接种剂提供了宝贵的知识库。
