“…Bacteria associated with S. latissima are also classically found in other brown macroalgae (Hollants et al 2013) and belong predominantly to the Proteobacteria and Bacteroidota phyla (Tourneroche et al 2020;Burgunter-Delamare et al 2023). At the class level, Alphaproteobacteria and Gammaproteobacteria (Liu et al 2022;Burgunter-Delamare et al 2023), Deltaproteobacteria, Bacilli, Flavobacteriia, Planctomycetia, and Verrucomicrobiae (Liu et al 2022) were found. Bacterial strain isolation experiments determined that strains were affiliated with Actinobacteria, Bacteroidetes, Firmicutes, Alpha-, Beta-, and Gammaproteobacteria and belonged to 21 genera (Wiese et al 2009).…”

BackgroundThe sugar kelp Saccharina latissima is a Laminariales species widely distributed in the Northern Hemisphere. Its physiology and ecology have been studied since the 1960s, given its ecological relevance in western temperate coasts. However, research interest has recently been rising, driven mainly by reports of negative impacts of anthropogenically induced environmental change and by the increased commercial interest in cultivating the species with several industrial applications for the resulting biomass. • ScopeWe reviewed peer-review research articles, reports, doctoral theses, and book chapters that targeted Saccharina latissima published from 2009 to May 2023. We include earlier publications only in the few cases where some key knowledge has not been recently supported or contested. • ConclusionsThe comprehensive view of the ecology, physiology, biochemical and molecular biology of S. latissima given here can fuel our understanding of its survival in nature and finetuning of cultivation methods for several specific applications, promoting a sustainable resource. Recent developments in genomics, transcriptomics and epigenomics have contributed significantly to improving the understanding of genetic diversity and molecular mechanisms underlying plasticity and local adaptation. Due to its wide distribution, S. latissima has to cope with a large variability of different environmental conditions and possible interactions between drivers. Therefore, S. latissima has developed a variety of physiological and biochemical mechanisms to adjust to environmental changes. Survival, growth, photosynthetic performance, metabolism, and 3 enzymatic activity are strongly affected by abiotic conditions, such as temperature, salinity, nutrient conditions or ocean acidification. Massive alterations regarding abundance, depth distribution and seasonal growth patterns of S. latissima have been reported recently throughout its distribution range, likely in response to climate change. These biogeographic changes are expected to continue, and although much effort has been dedicated to studying S. latissima responses to environmental drivers, there are still large knowledge gaps. keywords: acclimation -biogeography -climate change -local adaptation -macroalgae -marine ecology -metabolites -molecular biology -omics -physiology -seaweedwarming How S. latissima adjusts to its environment has been extensively studied, although unbalanced among drivers and geographical regions (see Responses to environmental drivers). In seaweeds, biochemical compounds, including pigments, carbohydrates, antioxidants, lipids, fatty acids and proteins, vary in composition and concentration depending on environmental conditions (summarized in Amsler 2008; Wiencke and Bischof 2012; Hurd et al. 2014; Zhang and Thomsen 2019). Furthermore, biological interactions with other taxa have the potential to profoundly change S. latissima growth and survival and are summarized in Biotic interactions. In addition to seasonal effects or differences on larger globa...

“…Epibionts, and in particular encrusting bryozoan, grow as colonies that cover the frond surface and form a barrier inhibiting nutrient and light absorption (Andersen et al 2019) and often cause loss of biomass due to increased drag and friction and decreased flexibility (Krumhansl et al 2011). Other common epibionts on S. latissima are hydroids, crustaceans, bivalves, sponges, tunicates, snails, benthic diatoms, and filamentous algae (Krumhansl et al 2011;Forbord et al 2020a;Corrigan et al 2023) and bacterial colonies (Liu et al 2022;Burgunter-Delamare et al 2023). Biofouling makes seaweed biomass less appealing for human consumption and affects the commercial value of the yield.…”

The sugar kelp Saccharina latissima has received intense scientific attention over the last decades. In recent years, interest in cultivation of the species has strongly increased in the North Atlantic Ocean and the Eastern Pacific Ocean, driven by the great potential of S. latissima to be utilised for various industrial applications, including food, feed, and biomaterials. Accordingly, current research has focused on improving farming methods and technology, environmental impacts, and site selection. In addition, many studies have investigated the varying chemical composition of S. latissima, extraction of commercially interesting components, and the use of the biomass and its derived components in various applications. This review provides acomprehensive overview of farming and applications of S. latissima from the last 15 years. Additional insights on other research topics, such as ecology, physiology, biochemical and molecular biology of S. latissima, are given in the first review, “The sugar kelp Saccharina latissima I: recent advances in a changing climate” (Diehl et al. 2023).

“…Similarly, eDNA analysis can be applied to study the microbial communities in the seawater of kelp aquaculture farms. Previous studies on the pathogenic bacteria that cause kelp disease have mainly focused on epiphytic bacteria present in kelp tissues [5,23,24]. However, research on epiphytic bacteria from kelp is limited to the isolation and culturing of various pathogenic bacteria.…”

Aquaculture farms cultivating Saccharina japonica are highly active in Wando, Korea, and Rongcheng, China. However, the yield of S. japonica significantly declined in the Rongcheng region in 2022 compared to previous records, whereas that in Wando remained at a normal level, presumably due to the presence of a pathogenic microbiome. We used environmental DNA (eDNA) metagenomic analysis to compare the microbial compositions of seawater from aquaculture farms in Wando and Rongcheng. Seawater samples were collected from one Korean site in Wando (WA) and two Chinese sites in Ailian Bay (AB) and Lidao Bay (LB). Metagenomic analysis focusing on the microbial 16S rRNA identified 38 phyla and 58 families of microbiomes in all regions. Potentially pathogenic bacterial groups associated with S. japonica in AB and LB were more abundant than in WA, suggesting their potential influence on mortality and the decline in the harvest yield of S. japonica. The microbial composition of WA was distinguished from those of the other two sites, which clustered together with higher similarity. Since the S. japonica aquaculture industry is important for both countries, this comparative eDNA monitoring is a valuable initiation towards the next step of problem-solving practices in coastal management in these two aquaculture systems.
