Phosphorus solubilizing bacteria (PSB) can promote the level of plant-absorbable phosphorus (P) in agroecosystems. However, little attention has been paid to PSB harboring abilities utilizing multiple sources and their potentials for heavy metal immobilization. In this study, we applied strategy stepwise acclimation by using Ca3(PO4)2, phytate, FePO4, AlPO4 as sole P source. We gained 18 possessing utilization, these belonged 8 genera (Acinetobacter, Pseudomonas, Massilia, Bacillus,...
Human gut Bacteroides and Parabacteroides species play crucial roles in human health are known for their capacity to utilize diverse polysaccharides. Understanding how these bacteria medicinal polysaccharides is foundational developing polysaccharides-based prebiotics drugs. Here, we systematically mapped the utilization profiles of 20 different by 28 species. The growth exhibited substantial variation across bacterial Ginseng promoted multiple species; contrast, Dendrobium selectively...
Abstract Spatial analysis of microbiomes at single cell resolution with high multiplexity and accuracy has remained challenging. Here we present spatial profiling a microbiome using sequential error-robust fluorescence in situ hybridization (SEER-FISH), highly multiplexed accurate imaging method that allows mapping microbial communities micron-scale. We show RNA can be increased significantly by rounds probe dissociation. Combined error-correction strategies, demonstrate SEER-FISH enables...
Microbial interactions can lead to different colonization outcomes of exogenous species, be they pathogenic or beneficial in nature. Predicting the species complex communities remains a fundamental challenge microbial ecology, mainly due our limited knowledge diverse mechanisms governing dynamics. Here, we propose data-driven approach independent any dynamics model predict from baseline compositions communities. We systematically validate this using synthetic data, finding that machine...
The honeybee gut microbiome is crucial for degrading diverse pollen glycans. Yet it unclear how this process shapes the interactions among bacteria. Here, we demonstrate a conditional mutualistic interaction between strains of two bacteria Bifidobacterium asteroides and Gilliamella apicola. When co-occurring in vitro vivo, provides complementary demethylation service to promote growth on methylated homogalacturonan, an enriched polysaccharide pectin. In exchange, shares digestive products...
Fiber optic gyroscope, as the mainstream component of inertial navigation system, has been widely used in aviation, aerospace, navigation, weapons, energy and other fields. However, size traditional fiber gyroscopes limits their application micro systems. This article proposes an integrated gyroscope with characteristics small high accuracy, which is expected to be future.
The control loop of high-precision fiber optic gyroscope (HPFOG) has inherent delay. If the loop-gain is constrained to suppress overshoot and vibration bias effect, bandwidth HPFOG will be limited a certain extent, which leads large angular rate tracking error when applied in high dynamic conditions affects performance system. A correction technique proposed reduce transient error. stability margin frequency characteristics after are analyzed, characteristic simulated. simulation results...
Abstract Suicidal behavior and non-suicidal self-injury (NSSI) are common in adolescent patients with major depressive disorder (MDD). Thus, delineating the unique characteristics of suicide attempters having MDD NSSI is important for prediction clinical setting. Here, we performed psychological biochemical assessments 130 youths NSSI. Participants were divided into two groups according to presence/absence attempts (SAs). Our results demonstrated that age lower than non-attempters...
Significance Ecological models usually take growth rate fitness as the essential driver of population dynamics. However, a widespread natural phenomenon, expansion in space (or range expansion) is often governed by both motility and growth. Microbial communities offer unique systems to study how an individual’s contributes competition among heterogeneous microbial populations during expansion. Here we show that heterogeneity can promote spatial segregation subpopulations structured via...
Although silica nanoparticles (SNPs) are generally thought to be biocompatible and safe, the adverse effects of SNPs were also reported in previous studies. cause follicular atresia via induction ovarian granulosa cell apoptosis. However, mechanisms for this phenomenon not well understood. This study focuses on exploring relationship between autophagy apoptosis induced by cells. Our results showed that 25.0 mg/kg body weight (b.w.)/intratracheal instillation 110 nm diameter spherical Stöber...
The effect of replacing Nd with misch metal (MM) on magnetic properties and thermal stability has been investigated melt-spun (Nd1-xMMx)13.5Fe79.5B7 ribbons by varying x from 0 to 1. All the alloys studied crystallize in tetragonal 2:14:1 structure single hard phase.
