Cultivation of novel Atribacterota from oil well provides new insight into their diversity, ecology, and evolution in anoxic, carbon-rich environments.

Background: The Atribacterota are widely distributed in the subsurface biosphere. Recently, the first Atribacterota isolate was described and the number of Atribacterota genome sequences retrieved from environmental samples has increased significantly; however, their diversity, physiology, ecology, and evolution remain poorly understood.

Results: We report the isolation of the second member of Atribacterota, Thermatribacter velox gen.

gen. nov., sp. nov., a bacterium isolated from oil sludge, and proposal of fam. nov.

A microaerophilic, Gram-negative, motile, and spiral-shaped bacterium, designated Y-M2, was isolated from oil sludge of Shengli oil field. The optimal growth condition of strain Y-M2 was at 25 °C, pH 7.0, and in the absence of NaCl.

Shumkonia mesophila gen. nov., sp. nov., a novel representative of Shumkoniaceae fam. nov. and its potentials for extracellular polymeric substances formation and sulfur metabolism revealed by genomic analysis.

A microaerophilic, mesophilic, chemoorganoheterotrophic bacterium, designated Y-P2, was isolated from oil sludge enrichment in China. Cells of the strain were Gram-stain-negative, non-motile, non-spore-forming, rod-shaped or slightly curved with 0.8-3.

Towards Efficient Federated Learning: Layer-Wise Pruning-Quantization Scheme and Coding Design.

As a promising distributed learning paradigm, federated learning (FL) faces the challenge of communication-computation bottlenecks in practical deployments. In this work, we mainly focus on the pruning, quantization, and coding of FL. By adopting a layer-wise operation, we propose an explicit and universal scheme: FedLP-Q (federated learning with layer-wise pruning-quantization).

Streptomyces typhae sp. nov., a novel endophytic actinomycete with antifungal activity isolated the root of cattail (Typha angustifolia L.).

A novel endophytic actinomycete with antagonistic activity against various phytopathogenic fungi, designated strain p1417, was isolated from the root of cattail (Typha angustifolia L.) collected from Yunnan Province, Southwest China. A polyphasic taxonomic study was carried out to establish the taxonomic status of this strain.

Characterization of a Novel Endophytic Actinomycete, sp. nov., and Its Biocontrol Potential Against on Tomato.

Bacterial wilt of tomato is a destructive disease caused by throughout the world. An endophytic actinomycete with antagonistic activity, designated strain LD120, was isolated from moss ( (Ludw) Fuernr). The biocontrol test demonstrated that co-inoculation by the isolate and the pathogen gave the greatest biocontrol efficiency of 63.

sp. nov., an endophytic actinomycete isolated from the root of cattail pollen ( L.).

A novel endophytic actinomycete, designated strain p1410, was isolated from the root of cattail pollen ( L.) and characterized using a polyphasic approach. The strain had morphological characteristics and chemotaxonomic properties identical to those of members of the genus .

Characterization of sp. nov. and Identification of the Putative Gene Cluster Encoding the Biosynthesis of Heliquinomycins.

A novel actinomycete producing heliquinomycin and 9'-methoxy-heliquinomycin, designated strain jys28, was isolated from rhizosphere soil of and characterized using a polyphasic approach. The strain had morphological characteristics and chemotaxonomic properties identical to those of members of the genus . It formed spiral chains of spores with spiny surfaces.

Actinomadura physcomitrii sp. nov., a novel actinomycete isolated from moss [Physcomitrium sphaericum (Ludw) Fuernr].

A novel endophytic actinomycete, designated strain LD22, was isolated from moss [Physcomitrium sphaericum (Ludw) Fuernr] collected from Yunnan Province, Southwest China. A polyphasic taxonomic study was carried out to establish the status of this strain. Morphological and chemotaxonomic characteristics of strain LD22 confirmed the affiliation of the isolate to the genus Actinomadura.

[Pollution Characteristics of Heavy Metals in PM Near Highway].

In this study, we evaluate the pollution characteristics of heavy metals in particulate matter with diameters less than 2.5 μm (PM) near highways. Three rounds of cluster sampling of PM were conducted on three highways, Changzhang, Changtong, and Wenhou, in peri-urban areas near Nanchang from March to August 2018.

Identifying the Pollution Characteristics of Atmospheric Polycyclic Aromatic Hydrocarbons Associated with Functional Districts in Ningbo, China.

Duplicate polyurethane foam based passive air samplers (PUF-PAS) were deployed at seven sites in Ningbo from November 1, 2014 to October 31, 2015 and were used to analyze 15 priority polycyclic aromatic hydrocarbons (PAHs). Higher benzo[a]pyrene toxic equivalent concentrations were observed in the industrial areas during wintertime. Correspondence analysis (CA) was used to characterize the PAH congener profiles associated with each functional district and their temporal variations.

Temporal variability of visibility and its parameterizations in Ningbo, China.

Simultaneous and continuous measurements of visibility, meteorological parameters and air pollutants were carried out at a suburban site in Ningbo from June 1, 2013 to May 31, 2015. The characteristics of visibility and their relationships with air pollutants and meteorological factors were investigated using multiple statistical methods. Daily visibility ranged from 0.
