Summary: This study aimed to investigate the effect of halotolerant plant growth-promoting endophytes on the growth parameters of barley, lettuce, and sunflower under salt stress conditions. The results showed that the inoculation of endophytes positively influenced the growth of tested plant species, with species-specific effects on key traits such as chlorophyll concentration, leaf development, root development, and biomass accumulation.

Summary: The potential spread of infectious diseases in response to climate change and rising sea surface temperatures in temperate regions has raised concerns over the past few decades. Different species of Vibrio, particularly Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus, have been correlated with human health risks in relation to extreme heat waves in the North Atlantic and North Sea regions. Studying the behavior and ecology of both pathogenic and non-pathogenic strains of these bacteria can provide insights into their native microbiome and how they disperse in coastal regions.

Summary: The engineered Shewanella marisflavi BBL25 can produce PHB by inserting polyhydroxyalkanoates synthesis genes from Ralstonia eutropha H16. High PHB production was achieved using barley straw hydrolysates as a carbon source. In addition, simultaneous production of PHB and electricity was demonstrated using the microbial fuel cell system.

Summary: Rising sea-surface temperature has led to an increase in the prevalence of Vibrio species in marine environments, particularly in temperate regions. This has resulted in a surge of Vibriosis infections worldwide. Using sea-surface temperature data around the English and Welsh coastlines, this study identifies locations where conditions for the presence and growth of Vibrio species are favorable. Shellfish samples collected from locations with increasing sea-surface temperature tested positive for the presence of Vibrio species, including aquaculture pathogens and human pathogenic species not previously reported in UK waters.

Summary: In this study, a quantitative NGS-based method was developed to accurately measure Vibrio sp. at the limit of quantification through DNA standards and digital PCR. The method represents an advancement in quantitative genomics and supports the development of statistical approaches for measurement uncertainties in NGS. It provides a useful tool for future metagenomic studies aiming to quantify microbial DNA in an absolute manner.

Summary: The research on Astyanax mexicanus provides an ideal model for testing the influence of maternal determinants on cell fate decisions. By generating pescoids and conducting cell transplantation experiments, a better understanding of the impact of cell fate decisions throughout the entire developmental process can be achieved, while also allowing for the replication of key embryonic developmental events.

Summary: In this study, a PMA-mPCR assay was developed for accurately screening viable vibrios in aquatic foods. The assay exhibited 100% specificity and maintained its sensitivity after PMA treatment. The results showed that the assay could detect viable V. parahaemolyticus, V. alginolyticus, and V. cholerae as low as 1.0 x 102 CFU/mL after 10 hours of enrichment. The practical application of the assay using 453 actual samples also demonstrated its accuracy in screening target vibrios in seafood.

Summary: This study identified genes associated with carbon source utilization, electron transfer systems, and hydrogen production systems in Shewanella marisflavi BBL25 through whole-genome sequencing. In addition, introducing the glk gene from S. marisflavi BBL25 into S. oneidensis MR-1 improved glucose consumption. The findings contribute to the understanding of sugar utilization, electron transfer systems, and hydrogen production systems in other Shewanella species.

Summary: The incidence of vibriosis is increasing globally due to changing climatic conditions that promote the growth of pathogenic Vibrio species. Environmental factors, such as temperature, salinity, total chlorophyll a, dissolved oxygen, and pH, were found to impact the occurrence of pathogenic Vibrio species. Long-term monitoring revealed an increase in Vibrio populations in the Chesapeake Bay region. The findings highlight the importance of predicting and managing Vibrio-related diseases in the face of climate change.

Summary: This study investigated the impact of sulfamethoxazole (SMX) on microbial activities and enzymatic expression in activated sludge. Metaproteomic analysis showed that SMX slightly affected the microbial community structure, with an enhanced activity of the genus Corynebacterium at increased SMX concentrations. These findings suggest a potential role of Corynebacterium in mitigating SMX risks in bioreactors.

Summary: This study investigated the biotransformation of organic micropollutants under anoxic conditions using a heterotrophic denitrifying bioreactor. The results showed that increasing nitrogen loading rates improved the removal efficiency of erythromycin, roxithromycin, and bisphenol-A, and specific bacterial taxa were identified as indicators related to the biodegradation of these compounds. The study also found that increasing primary metabolic activity did not enhance the removal rates of the organic micropollutants, suggesting that bacterial composition is more influential than cometabolism.

Summary: The study compared the potential to produce volatile fatty acids (VFA) from sewage sludge, both raw and thermally pre-treated. In batch mode, raw sludge obtained the highest maximum VFA yield at pH 8, while pre-treated sludge achieved a lower value. Continuous reactor operation showed that thermal hydrolysis pre-treatment (THP) did not significantly influence VFA yields. Microbial community analysis revealed that the phylum Fumicutes was predominant in both reactors and the enzymatic profiles involved in VFA production were similar regardless of the substrate fed.

Summary: This study examined the effects of the 2016 Marine Heatwave on the plankton communities in the Great Barrier Reef. Analysis of plankton samples collected from November 2014 to August 2016 revealed an increase in Planctomycetes and bacteria belonging to the Vibrio and Synechococcus genus during and after the heatwave. Additionally, potential pathogenic Vibrio species associated with diseases in aquatic animals were detected four months after the heatwave, indicating a spread of potentially harmful bacteria across the reef.

Summary: This study isolated a Gram-negative, aerobic bacterium named PTE2(T) from laboratory-reared Japanese sea cucumber larvae. Phylogenetic analysis revealed that PTE2(T) was closely related to Thalassotalea sediminis N211(T), but had some differences, indicating the novelty of this strain. Based on genome-based taxonomic approaches, PTE2(T) is proposed as a new species, Thalassotalea hakodatensis sp. nov.

Summary: Strain PT1(T), a rod-shaped bacterium isolated from laboratory-reared larvae of sea cucumber Apostichopus japonicus, demonstrated similarities to Neptuniibacter marinus ATR 1.1(T) and Neptuniibacter caesariensis MED92(T) with sequence similarities of 98.2% and 98.1%, respectively, based on the analysis of 16S rRNA gene nucleotide sequences. However, the average nucleotide identity (ANI) and in silico DNA-DNA hybridization (DDH) values among these three strains were below 95% and 70%, confirming the novel status of PT1(T). Based on the genomic approach, a new species, Neptuniibacter victor sp. nov., is proposed for PT1(T).
