Summary: Elevated concentrations of nitrite are toxic to fish and can cause a myriad of well-documented issues. This study focused on exploring the effects of sublethal concentrations of nitrite on fish health, specifically on fish tissue microbiomes. The results showed that sublethal concentrations of nitrite caused significant changes in the microbial composition of fish tissue microbiomes, independent of the water microbiome. These changes could have potential negative effects on fish populations, including increased infection risks and disruption of organ systems.

Summary: Incorporating environmentally sustainable plant-based protein sources into aquafeeds is important, but the effects of specific plant proteins on different fish species need to be evaluated. Previous studies showed that wheat gluten at less than 4% inclusion had a negative impact on the growth and survival rate of juvenile cobia. In this study, the effects of wheat gluten inclusion in a plant-based diet for juvenile European sea bass were evaluated, and it was found that 4% dietary wheat gluten was well tolerated by the fish.

Summary: Business platforms have been widely adopted in B2C markets and are now gaining popularity in the B2B world. However, our understanding of platform adoption in B2B is not as advanced as in B2C. B2B platforms have unique complexities and require different managerial policies for success. To address this gap, a novel framework is proposed to better understand the dynamics of B2B platform creation and growth, exploring the value differences between B2B and B2C platforms and their managerial implications.

Summary: Ocean acidification can affect marine molluscs, but transgenerational plasticity may mitigate some effects. This study investigated how the microbiome can be influenced by transgenerational exposure to ocean acidification in Sydney Rock oysters. The results showed that parental exposure to elevated PCO2 altered the bacterial community composition in both eggs and larvae, with certain Rhodobacteraceae ASVs increasing or decreasing in abundance. These findings suggest that the transfer of maternal microbiomes to larvae is affected by exposure to ocean acidification and may contribute to transgenerational plasticity.

Summary: Atlantic sea scallops are economically important bivalves on the northeastern coast of North America. However, the larval maturation phase in hatcheries is often faced with high mortality events, attributed to bacterial infections or altered microbial communities. This study characterized the bacterial communities in wild and hatchery larvae, as well as tank biofilms, and found that hatchery larvae had lower bacterial richness but similar bacterial community composition to wild larvae and tank biofilms. The fluctuation of bacterial richness and community similarity in tank samples showed correlation to the lunar cycle.

Summary: This paper examines the reaction of bank liquidity creation to business cycle fluctuations. Through analyzing panel data of US banks, it is found that bank liquidity creation is procyclical, meaning that banks create more liquidity during economic expansions and less liquidity during recessions. This result holds across bank size groups, suggesting that bank liquidity creation can amplify business cycle fluctuations.

Summary: As we approach the post-antibiotic era, the need for new antimicrobial compounds is urgent. Microorganisms have been a rich source of antibiotics, but the rediscovery of known antibiotics and the limited accessibility of most microorganisms in the environment have prompted the exploration of natural microbial communities using novel approaches. This review discusses how sequence-based analyses have revealed the abundant potential for secondary metabolite production in soil, marine, and host-associated microbiomes, with a focus on non-ribosomal peptides and polyketides. However, the complexity of natural microbiomes and the lack of standardized methodology pose challenges in comparing different biomes. Nevertheless, even commonly sampled microbiomes hold promise for discovering novel natural products, and the development of approaches to harness the vast biosynthetic diversity of natural microbiomes for the procurement of new antibiotics is discussed.

Summary: This study used a multi-omics approach to investigate the effects of environmental factors on the accumulation of monoterpenes in citrus peel. It was found that soil nutrients and root-associated microbiome play important roles in the production of monoterpenes. The soil environment, including high salinity and certain nutrients, can enhance monoterpene content in citrus peel by promoting the expression of specific genes. Additionally, interactions between rhizosphere microorganisms and the host immune system can activate terpene synthesis and contribute to monoterpene accumulation.

Summary: Many microbial secondary metabolites have antimicrobial properties, but some also have non-antimicrobial functions that influence the physiology and ecology of the producer and their neighbors. Tropodithietic acid (TDA) is a versatile bacterial secondary metabolite with multiple functions, including broad-spectrum antimicrobial activity and signaling effects on gene expression and phenotypic traits in other bacteria. TDA-producing bacteria can reduce the abundance of related species and fast-growing heterotrophic bacteria in microbial communities.
