Although it has been known that some terrestrial bacteria utilize T4LHyp as carbon and nitrogen source via a T4LHyp gene cluster, which and how marine microorganisms catabolize T4LHyp still remains unclear. Here, five T4LHyp-utilizing marine bacterial strains, <i>Halomonas</i> sp. 5021, <i>Salinicola</i> sp. 4072, <i>Alteromonas</i> sp. 6022, <i>Alteromonas</i> sp. 5112 and <i>Alteromonas</i> sp. 30521, were isolated from hydrothermal vent sediment samples collected from the southwest Indian Ocean. While <i>Halomonas</i> sp. 5021 can utilize T4LHyp as both a nitrogen and carbon source, the other four strains can utilize T4LHyp as only a nitrogen source. Then, the T4LHyp catabolic mechanisms of <i>Halomonas</i> sp. 5021 and <i>Salinicola</i> sp. 4072, as a representative of the four strains, were further investigated by genomic, transcriptional, and biochemical analyses. <i>Halomonas</i> sp. 5021 adopts an intact T4LHyp gene cluster containing four enzymes to catabolize T4LHyp into NH₃ and α-ketoglutarate to provide nitrogen and carbon sources for its growth. Compared to <i>Halomonas</i> sp. 5021, <i>Salinicola</i> sp. 4072 lacks an α-KGSA dehydrogenase gene in the T4LHyp gene cluster and can only catabolize T4LHyp into NH₃ and α-ketoglutarate semialdehyde to provide a nitrogen source for its growth. Bioinformatic investigation showed that the 5021-like and 4072-like T4LHyp gene clusters are predominantly found in bacteria from <i>Pseudomonadota</i>, which are widely distributed in multiple marine habitats. Thus, <i>Pseudomonadota</i> bacteria are likely the dominant group to drive the recycling and mineralization of T4LHyp in the ocean.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s42995-024-00272-8.</p>","PeriodicalId":53218,"journal":{"name":"Marine Life Science & Technology","volume":"7 1","pages":"187-202"},"PeriodicalIF":5.8,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11871167/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143544442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we evaluate phytoplankton biomass and community structure changes using lipid biomarkers, accompanying ocean circulation and nutrient variations in surface waters collected in spring and summer of 2017-2018 at 118 sites in the East China Sea off the Zhejiang coast. High biomass of diatoms, inferred from brassicasterol concentrations, shifted from the south in spring to the north in summer, while high dinoflagellate biomass, inferred from dinosterol concentrations, occurred mainly in the Changjiang (Yangtze) River plume and adjacent areas in both seasons. Seasonal variation in phytoplankton distribution was linked to the spatial extents of water masses such as the Changjiang Diluted Water (CDW) and the intrusion of the Kuroshio Subsurface Water (KSSW). A three end-member mixing model was applied to quantify water mass contributions. The results showed that an increase in the KSSW (from 0 to 40%) and a decrease in the CDW (from 100 to 20%) resulted in a significant (20%) increase in diatom proportions and a significant (20%) decrease in dinoflagellate proportions. Dinoflagellate proportions were highest in the CDW-dominated region, while diatoms and total phytoplankton biomass were higher in the CDW-KSSW mixing region and the KSSW-dominated region.

However, the contribution of biophysical and biochemical CCMs to algal carbon fixation remains unclear. Here, we used ethoxyzolamide (EZ) inhibitors of carbonic anhydrase and 3-mercaptopicolinic acid (MPA) inhibitors for phosphoenolpyruvate carboxykinase to examine the importance of biophysical and biochemical CCMs in photosynthesis of the green macroalga <i>Ulva prolifera</i>. The culture experiments showed that the carbon fixation of the species declined when EZ inhibited the biophysical CCM, while the increase in cyclic electron flow around the photosystem I indicated a more active biochemical CCM, contributing to ~ 50% of total carbon fixation. The biophysical CCM was also reinforced when MPA inhibited the biochemical CCM. In a comparison, the biophysical CCM can compensate for almost 100% of total carbon fixation. The results indicate that biophysical CCMs dominate the process of carbon fixation of <i>U. prolifera</i> while biochemical CCM plays a supporting role.

The impacts of elevated CO₂ levels on kelps may induce far-reaching effects throughout the marine food web, with potential consequences for biodiversity and ecosystem functions. This study considers the kelp <i>Macrocystis pyrifera</i> and its symbiotic microorganisms as a holistic functional unit (holobiont) to examine their collective response to heightened CO₂ levels. Over a 4 month cultivation from the fertilization of <i>M. pyrifera</i> gametes to the development of juvenile sporophytes, our findings reveal that elevated CO₂ levels influence the structure of the <i>M. pyrifera</i> symbiotic microbiome, alter metabolic profiles, and reshape microbe-metabolite interactions using 16S rRNA amplicon sequencing and liquid chromatography coupled to mass spectrometry analysis. Notably, <i>Dinoroseobacter</i>, <i>Sulfitobacter</i>, <i>Methylotenera</i>, <i>Hyphomonas</i>, Milano-WF1B-44 and <i>Methylophaga</i> were selected as microbiome biomarkers, which showed significant increases in comparative abundance with elevated CO₂ levels. Stress-response molecules including fatty-acid metabolites, oxylipins, and hormone-like compounds such as methyl jasmonate and prostaglandin F2a emerged as critical metabolomic indicators. We propose that elevated CO₂ puts certain stress on the <i>M. pyrifera</i> holobiont, prompting the release of these stress-response molecules. Moreover, these molecules may aid the kelp's adaptation by modulating the microbial community structure, particularly influencing potential pathogenic bacteria, to cope with environmental change. These results will enrich the baseline data related to the chemical interactions between the microbiota and <i>M. pyrifera</i> and provide clues for predicting the resilience of kelps to future climate change.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s42995-024-00259-5.</p>","PeriodicalId":53218,"journal":{"name":"Marine Life Science & Technology","volume":"6 4","pages":"700-712"},"PeriodicalIF":5.8,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11602886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142774800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
