Introduction The endosphere of a plant is an interface containing thriving community endobacteria that can affect growth and potential for bioremediation. Eichhornia crassipes aquatic macrophyte, adapted to estuarine freshwater ecosystems, which harbors diverse bacterial community. Despite this, we currently lack predictive understanding how E. taxonomically structure the endobacterial assemblies across distinct habitats (root, stem, leaf). Methods In present study, assessed endophytic bacteriome from different compartments using 16S rRNA gene sequencing analysis verified in vitro beneficial isolated endophytes . Results discussion Plant displayed significant impact on structures. Stem leaf tissues were more selective, exhibited lower richness diversity than root tissue. taxonomic operational units (OTUs) showed major phyla belonged Proteobacteria Actinobacteriota (> 80% total). most abundant genera sampled was Delftia both stem samples. Members family Rhizobiaceae, such as Allorhizobium- Neorhizobium-Pararhizobium-Rhizobium mainly associated with tissue, whereas Nannocystis Nitrospira families Nannocystaceae Nitrospiraceae, respectively, statistically significantly Piscinibacter Steroidobacter putative keystone taxa Most bacteria effects known stimulate induce resistance stresses. This study provides new insights into distribution interaction Future communities, culture-dependent -independent techniques, will explore mechanisms underlying wide-spread adaptability various ecosystems contribute development efficient consortia bioremediation promotion.

Abstract Intensification of aquaculture practices resulted in increased ammonia production the culture systems. Lack proper management system will result elevated ammonia, which adversely affects species. Moreover, with ongoing global warming, fish metabolism and excretion are expected to increase. This, coupled hypoxic condition, exacerbates severity toxicity. Ammonia toxicity can alter growth biochemical, physiological immunological responses fish. Several factors such as pH, temperature, salinity, dissolved oxygen, species life stages fish, physical activity, feeding stress influence A understanding these is a prerequisite for successful aquaculture. The changes caused by hinder homeostasis that eventually increases their susceptibility diseases. This review discusses affecting various physiological, haematological, histological induced ammonia.

Soil microbial biodiversity provides many useful services in cities. However, the ecology of communities urban soils remains poorly documented, and studies are required to better predict impact land use. We characterized (archea/bacteria fungi) Dijon (Burgundy, France). Three main uses were considered – public leisure, traffic, agriculture sub-categorized sub-land according indexes management practices. Microbial biomass diversity determined by quantifying high-throughput sequencing soil DNA. Variation partitioning analysis was used rank physicochemical characteristics their relative contribution variation communities. Urban harbored high levels that varied uses. 1.8 times higher leisure traffic sites than sites. Fungal richness increased 25 % soils, bacterial lower (by 20 %) soils.

Abstract Soil fertility is key point to pastures systems and drives the microbial communities their functionality. Therefore, an understanding of interaction between soil can increase our ability manage pasturelands maintain functioning productivity. This study probed influence on in tropical Brazil. samples, gathered from top 20 cm twelve distinct areas with diverse levels, were analyzed via 16S rRNA sequencing. The soils subsequently classified into two categories, namely high (HF) low (LF), using K-Means clustering. random forest analysis revealed that had more bacterial diversity, predominantly Proteobacteria, Nitrospira, Chloroflexi, Bacteroidetes, while Acidobacteria increased (LF) soils. High exhibited complex network interactions enrichment nitrogen-cycling groups. Additionally, functional annotation based varied clusters. Microbial groups HF demonstrated enhanced functions such as nitrate reduction, aerobic ammonia oxidation, aromatic compound degradation. In contrast, LF soil, predominant processes ureolysis, cellulolysis, methanol methanotrophy. Our findings expand knowledge about how pastures.

Increasing nitrogen (N) input to coastal ecosystems poses a serious environmental threat. It is important understand the responses and feedback of N removal microbial communities, particularly nitrifiers including newly recognized complete ammonia-oxidizers (comammox), improve aquaculture sustainability. In this study, we conducted holistic evaluation functional communities responsible for nitrification by quantifying sequencing key genes comammox Nitrospira-amoA, AOA-amoA, AOB-amoA Nitrospira-nxrB in fish ponds with different feeding levels evaluated contribution process through experiments mixing pure cultures. We found that higher dramatically increased N-related concentration, affecting nitrifying communities. Compared AOA AOB, Nitrospira NOB were more sensitive changes. Unexpectedly, detected an equivalent abundance AOB observed increase proportion clade A feeding. Furthermore, simplified network shift keystone species from fish-feeding ponds. Random forest analysis suggested community played critical role eutrophic (40–70 μM). Through additional experiment cultures, primary contributor at 200 μM ammonium. These results advance our understanding highlight importance driving systems.
