Article Synopsis
- Eight multifunctional strains were isolated from root nodules to improve rhizosphere soil microbial communities, showing abilities like nitrogen fixation, auxin production, and phosphate solubilization.
- The strains significantly enhanced growth parameters in seedlings, with particular strains (LB69 and LQ10) showing notable increases in germination rate, root length, and vigor.
- The application of these strains also boosted antioxidant enzyme activity, suggesting their potential use as biofertilizers to promote plant growth and stress resistance.
Soil heavy metals in karst areas have obvious high background value characteristics. Conducting county-level soil heavy metal ecological risk assessment and identifying heavy metal sources in karst areas are of great significance for soil pollution control and land resource management. Taking Pingguo City, a typical karst county in Guangxi Province, as the study object, 3 151 surface and deep soil samples were collected using the grid method and combined to form 785 analytical samples.

Objective: The aim of our study was to investigate the 95% effective dose (ED 95 ) of intranasal dexmedetomidine for the prevention of emergence agitation after inhalational anaesthesia for paediatric ambulatory surgery.
[Effects of exogenous microorganisms on seedling growth and soil microbial community of ].

Article Synopsis
- A pot experiment using Biolog microplates and PLFA technology tested if bacteria (YB706 and BK8) could enhance soil nutrients, microbial communities, and plant growth.
- Results showed that treated soils had significantly higher levels of alkali-hydrolyzed nitrogen and available phosphorus compared to the control, with plant height increases of 59.1% for YB706 and 63.9% for BK8.
- Both bacteria enhanced soil microbial diversity, with greater richness and abundance of microorganisms, and improved microbial community indices, suggesting positive effects on soil health and seedling growth.
By using Biolog Ecoplate system, this paper studied the structure and functional diversity of soil microbial community under different vegetation types in Wuyishan National Nature Reserve, aimed to probe into the effects of vegetation type on the diversity of soil microbial community. The results showed that the soil chemical properties, soil enzyme activities, and average well color development (AWCD) were higher in natural forest than in planted forest, and were the lowest in abandoned field. The AWCD reflecting soil microbial activity and functional diversity was increased with increasing incubation time, but there existed significant differences among different vegetation types.
