Responses of Soil Microbial Survival Strategies and Functional Changes to Wet-Dry Cycle Events.

Soil microbial taxa have different functional ecological characteristics that influence the direction and intensity of plant-soil feedback responses to changes in the soil environment. However, the responses of soil microbial survival strategies to wet and dry events are poorly understood. In this study, soil physicochemical properties, enzyme activity, and high-throughput sequencing results were comprehensively anal0079zed in the irrigated cropland ecological zone of the northern plains of the Yellow River floodplain of China, where was grown for a long period of time, converted to after a year, and then was planted.

Integrative conjugative elements mediate the high prevalence of in spp. of animal source.

The emergence and spread of have greatly weakened the function of tigecycline. Although studies have demonstrated the significance of as carriers for , the epidemic mechanism and characteristics of in remain unclear. Herein, we deciphered that the gene in VRIII of SXT/R391 ICEs was a hotspot for the integration of -bearing mobile genetic elements by genomic analysis.

Epidemiological and Molecular Characteristics of and Co-Occurrence Carbapenem-Resistant .

Objective: Carbapenem-resistant (CRKP) has emerged and spread worldwide. It can usually cause a serious threat complicating treatment options in clinical settings. However, treatment options are limited.

A novel method of simultaneous NH and NO removal using Fe cycling as a catalyst: Feammox coupled with NAFO.

The feasibility of using Feammox coupled with nitrate-dependent Fe(II) oxidizing (NAFO) to cause the simultaneous conversion of NH and NO was explored by inoculation with Feammox sludge and the use Fe cycling as catalyst. After 61days operation, the simultaneous conversion of NO and NH occurred with the presence of interconversion between Fe(III) and Fe(II). The conversion ratio of NH to NO stabilized at 0.
