The Description of Pseudoalteromonas apostichopi sp. nov., Vibrio apostichopi sp. nov., and Marinobacter apostichopi sp. nov. from the Fertilized Eggs and Larvae of Apostichopus japonicus. Curr Microbiol 2024; 81:246.

Abstract
Three novel bacterial strains, FE4T, FE10T, and LA51T, which are phylogenetically affiliated to the genera Pseudoalteromonas, Vibrio, or Marinobacter, respectively, isolated from fertilized eggs and juveniles of sea cucumber Apostichopus japonicus were characterized by a genome-based taxonomical approach including multilocus sequence analysis (MLSA) combined with classical phenotypic and chemotaxonomic characterizations. A molecular network reconstructed on the basis of nucleotide sequences of four phylogenetic maker protein genes revealed that the strains FE4T, FE10T, and LA51T were closely related to Pseudoalteromonas shioyasakiensis, Vibrio lentus, and Marinobacter similis, respectively. Average nucleotide identity (ANI) comparisons against phylogenetically related species to FE4T, FE10T, and LA51T demonstrated that each newly described strain could not be identified as any previously described species within each genus showing < 95% ANI: 91.3% of FE4T against P. shioyasakiensis JCM 18891 T, 92.6% of FE10T against "V. bathopelagicus" Sal10, and 92.6% of LA51T against M. similis A3d10T, in maximum, respectively. Here, we show molecular phylogenetic, genomic, phenotypic, and chemotaxonomic features of the newly described species FE4T, FE10T, and LA51T. We also propose Pseudoalteromonas apostichopi sp. nov. with FE4T (JCM 36173 T = LMG 33143 T) as the type strain, Vibrio apostichopi sp. nov. with FE10T (JCM 36174 T = LMG 33144 T) as the type strain, and Marinobacter apostichopi sp. nov. with LA51T (JCM 36175 T = LMG 33145 T) as the type strain.

Abstract
Marine bacterioplankton underpin the health and function of coral reefs and respond in a rapid and sensitive manner to environmental changes that affect reef ecosystem stability. Numerous meta-omics surveys over recent years have documented persistent associations of opportunistic seawater microbial taxa, and their associated functions, with metrics of environmental stress and poor reef health (e.g. elevated temperature, nutrient loads and macroalgae cover). Through positive feedback mechanisms, disturbance-triggered heterotrophic activity of seawater microbes is hypothesised to drive keystone benthic organisms towards the limit of their resilience and translate into shifts in biogeochemical cycles which influence marine food webs, ultimately affecting entire reef ecosystems. However, despite nearly two decades of work in this space, a major limitation to using seawater microbes in reef monitoring is a lack of a unified and focused approach that would move beyond the indicator discovery phase and towards the development of rapid microbial indicator assays for (near) real-time reef management and decision-making. By reviewing the current state of knowledge, we provide a comprehensive framework (defined as five phases of research and innovation) to catalyse a shift from fundamental to applied research, allowing us to move from descriptive to predictive reef monitoring, and from reactive to proactive reef management.
