Summary: The study found that coral-associated bacteria and Symbiodiniaceae are crucial for the health of coral hosts. The bacterial communities showed high dynamics over time and space, but were not affected by monsoon seasons, while the Symbiodiniaceae communities remained consistent. Both bacteria and Symbiodiniaceae played important roles in supporting the functioning of the coral holobiont.

Summary: This study aims to investigate the differential ability of different Endozoicomonas species to respond to environmental changes. Using a combination of metabarcoding, genomics, and comparative genomics approaches, the study found that different dominant Endozoicomonas species existed in coral colonies separated by a small distance, including a newly discovered species. Furthermore, these dominant Endozoicomonas species exhibited different potentials to scavenge reactive oxygen species, indicating differences in their response to the environment.

Summary: This study demonstrated that antibiotics can alter the composition and reduce the diversity of coral-associated bacteria, leading to decreased oxygen consumption and activation of host immunity without directly impairing symbiotic algae photosynthesis. These findings highlight the importance of coral-associated bacteria for holobiont health and provide insights for future experiments.

Summary: In this study, coral cell-associated microbial aggregates (CAMAs) were comprehensively characterized, revealing the presence of Endozoicomonas and Simkania bacteria. Endozoicomonas may colonize and aggregate with the host coral using secretion systems and/or pili and potentially provide vitamins. Simkania, on the other hand, may obtain acetate and heme from neighboring Endozoicomonas. This research provides detailed insights into coral endosymbionts, improving our understanding of coral physiology and health, and offering important knowledge for coral reef conservation in the face of climate change.

Summary: This study investigates the impact of coral-associated bacteria communities on the heat tolerance of coral holobionts. The researchers found that antibiotics treatment significantly altered coral-associated bacteria communities and caused major changes in both coral and algal symbiont gene expression. Heat stress impaired protein translation and activated DNA repair processes, while antibiotics treatments caused downregulation of amino acid and ion transport and metabolism genes. Combined antibiotics-heat stress treatments exacerbated the response to heat stress, indicating the importance of coordinated metabolic interactions between corals and their associated microbial communities for coral holobiont health and heat tolerance.

Summary: For the first time, this study utilized aDNA from ancient fossil coral fragments to gain new insights into the declining western Atlantic reef ecosystem. The results showed the possibility of sequencing aDNA from reef cores and comparing it with modern-day genetic variation. The study also revealed the stability of the coral holobiont over time and laid the foundation for studying the impacts of environmental stress and evolutionary constraints.

Summary: Beetles rely on endosymbionts to synthesize aromatic amino acids that reinforce their protective cuticle. The exponential increase in endosymbiotic titer observed in Sitophilus oryzae/Sodalis pierantonius interaction is triggered by host carbohydrate intake. Host survival and cuticle biosynthesis are influenced by the nutritional status and food quality and availability.

Summary: There is increasing evidence that the composition of microorganisms within a host plays a crucial role in the overall health of the holobiont. This study used sequencing techniques to analyze the coral host and its associated algal and bacterial communities. The results showed that reef zones have an impact on the structure of these communities at different scales, and there may be genotype by genotype interactions between the host and bacteria in the coral. These findings highlight the importance of local reef conditions in shaping the unique combinations of host-microbial partnerships.

Summary: Coral research is transitioning to the genomic era, where effective pairing of high-quality genomes with taxonomic characterizations and ecological relevance is needed. Lack of a formal framework calls for consensus guidelines to reconcile different types of data, especially for the metaorganism nature of the coral holobiont. While exhaustive taxonomic characterization of all coral holobiont member species is currently not feasible, guidelines on minimal, recommended, and ideal-case descriptions will aid in future referencing and comparative studies.

Summary: Frequent and intense heat waves have detrimental effects on reef-building corals, leading to bleaching and death. The tolerance of corals to heat stress depends on their genetic composition. A study comparing acute and chronic heat stress on coral Porites cylindrica found that regardless of the temperature treatment, corals at 33 degrees Celsius showed signs of bleaching and decreased photochemical efficiency. The symbiotic communities remained stable, dominated by the same genus Clado-copium (C15).

Summary: The symbiotic bacterial communities in high-latitude corals exhibit significant seasonal variations, with rapid restructuring of community structures. Sea surface temperature is identified as the major contributor to microbial community structure variation. The high diversity and abundance of symbiotic bacteria under high temperatures help corals maintain physiological functions.

Summary: Steroidal oestrogens, classified as endocrine disruptors and carcinogens, accumulate in urban estuarine sediments. Actinobacteria, particularly Rhodococcus sp. strain B50, possess genes involved in oestrogen degradation, including aedA and aedB, which encode enzymes responsible for A-ring cleavage. Actinobacterial oestrone 4-hydroxylase (AedA) is identified as a cytochrome P450-type monooxygenase. 4-hydroxyestrone 4,5-dioxygenase genes and extracellular metabolites PEA and HIP can be used as biomarkers to study oestrogen biodegradation in urban estuarine sediments.

Summary: DEHP, the most widely used plasticizer globally, accumulates in estuarine sediments and poses adverse effects on ecosystems and human health. Through integrated meta-omics approaches, it was found that DEHP biodegradation in estuarine sediments mainly depends on synergistic networks between denitrifying proteobacteria. The side chain hydrolysis of DEHP is identified as the rate-limiting step in its degradation process.

Summary: This study identified key estrogen catabolic genes in the actinobacterium Rhodococcus sp. strain B50, including aedF and aedK, involved in the degradation of estrogenic A-ring. It also discovered a unique meta-cleavage product, 4,5-seco-estrogenic acid (C-18), during actinobacterial estrogen degradation. Differentiating the estrogenic metabolite profile and degradation genes of actinobacteria and proteobacteria enables the identification of potential estrogen degraders in various ecosystems through liquid chromatography-mass spectrometry analysis and polymerase chain reaction-based functional assays.

Summary: This research developed a fast and efficient method to convert soybean pulp waste into amino acids required for fermentative protein production. The method involves a two-protease cascade reaction that can completely hydrolyze soybean pulp into oligopeptides and individual amino acids in 3 hours. Compared to conventional methods, this enzymatic process preserves more amino acids and has lower cost for protease purification.
