Summary: Co-microcapsules containing L. rhamnosus and krill oil were prepared using whey protein as wall material through spray drying. Viability of the microcapsules and co-microcapsules at different drying process temperatures was above 1 x 1010 CFU/mL. The main phospholipid detected in the co-microcapsules was phosphatidylethanolamine, and the fatty acids profile revealed a low content of SFA but high levels of MUFA and PUFA. The survivability of L. rhamnosus in the co-microcapsules was influenced by storage temperature, with higher temperatures decreasing the water activity range for stable viability.

Summary: The present study focused on using phospholipid fatty acid (PLFA) technology to investigate the rhizosphere soil microorganisms of Minghui 86 (MH) and Yangdao No.6 (YD) rice at different growth stages. The results showed that the rhizosphere soil microorganisms of MH and YD had distinct sensitivities to exogenous phosphorus and had a certain inhibitory effect on rice enhancement. The sensitivity of rice root soil microorganisms to exogenous phosphorus also varied in different growth stages of rice. Bacteria were the dominant microorganism in the soil microbial community of rice roots, and the addition of exogenous phosphorus had a certain impact on the structure of the soil microbial communities. Through analyzing the microbial community characteristics, the study provided further understanding of the effect of exogenous phosphorus on the microbial community characteristics of rice rhizosphere soil and its impact on ecological functions.

Summary: The analysis of phospholipid fatty acids (PLFAs) is a common method to quantify soil microbial abundance and analyze community structure. This study validates the quantitative sensitivity of complete neutral lipid (NLFA) and glycolipid fatty acid (GLFA) profiles in PLFA extraction method. The study finds that fatty acid markers show consistent taxonomic specificities across the three lipid fractions. Fatty acid profiles from soil extracts exhibit stronger differences between PLFAs, NLFAs, and GLFAs, indicating their different community properties. The concomitant measurement of fatty acid profiles from all three lipid fractions is a low-cost and potentially information-rich addition to the PLFA method.

Summary: This study investigated the temporal variation of soil extracellular enzyme (EE) activity in a tropical terra-firme forest. Results showed that EE activity peaked during the drier season, associated with increased leaf litterfall and negatively correlated with precipitation. Soil nutrients were weakly related to EE activity, but extractable N was related in the top 5 cm of soil. The study suggests that EE activity is synchronized with precipitation-driven substrate inputs and depends on the availability of N, with dynamic shifts in microbial activity in response to climate seasonality and resource limitation.

Summary: In temperate, boreal and arctic soil systems, microbial biomass increases during winter and decreases in spring, potentially stabilizing soil carbon during winter. The causes of this increase, whether it is due to changes in microbial physiology or community composition, remain unclear. In a laboratory study, soil microbial communities responded strongly to cooling, with reduced growth and cell division but unchanged glucose uptake and respiration. Microbes invested glucose-derived carbon in unsaturated fatty acids at colder temperatures, potentially as a precaution to reduced temperatures. This immediate response of soil microorganisms to soil cooling could help explain the high microbial biomass carbon observed in temperate soils in winter.

Summary: Marine sponges play a critical role in marine ecosystems as filter-feeders and reef-builders, and they harbor dense communities of microbes. These microbes contribute to the processing of dissolved organic matter (DOM). A study using metaproteogenomics and laboratory incubations found that a dominant gammaproteobacterial symbiont in a marine sponge expressed a pathway for the import and dissimilation of taurine, a common metabolite in marine sponges. The symbiont also imported and used DMSP as a carbon and sulfur source. These findings highlight the importance of biogenic sulfur compounds in the interaction between marine sponges and their microbial symbionts.

Summary: Rapid Arctic warming has both positive and negative effects on soil carbon loss and CO2 uptake by plants. While permafrost thaw enhances CO2 release from soil organic matter decomposition, plants can also stimulate decomposition near their roots. However, the sensitivity of permafrost peat soils to plant-induced priming is low, suggesting limited impact of plant-released organic compounds on peat decomposition.

Summary: This study focuses on the data-poor Arctic Ocean shelves north of Siberia, which are experiencing rapid warming and increasing nitrogen input due to permafrost thaw. The research finds that nitrogen concentrations in water column and sediments are elevated near large river mouths. N2O concentrations are weakly correlated with dissolved nitrogen and turbidity, indicating the influence of particulate matter from rivers and coastal erosion. The study suggests that N2O dynamics in the region are influenced by water column N2O consumption and production.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
