BACKGROUND/PURPOSE Microbial biomass plays an important role in nutrient transformation and conservation of forest and grassland ecosystems. The objective of this study was to determine the microbial biomass among three vegetation types in subalpine mountain forest soils of Taiwan. METHODS Tatachia is a typical high-altitude subalpine temperate forest ecosystem in Taiwan with an elevation of ...

Five different protocols, viz. Andleeb et al. (2012), Shrivastava et al. (2012), Phenol chloroform DNA extraction method, Roboscreen Kit method and Phenol chloroform triton method, were tested for DNA extraction from skin samples of Leopard (Panthera pardus) preserved in formalin over a period of two to five months. Among these procedures, the Phenol chloroform triton method was proved to be th...

The fate of (137)Cs derived from the Fukushima nuclear accident fallout and associated radiological hazards are largely dependent on its mobility in the surface soils of forest ecosystems. Thus, we quantified microbial and adsorptive retentions of (137)Cs in forest surface (0-3 cm) soils. The K(2)SO(4) extraction process liberated 2.1%-12.8% of the total (137)Cs from the soils. Two soils with a...

Short-term response of soil C mineralization following drying/rewetting has been proposed as an indicator of soil microbial activity. Houston Black clay was amended with four rates of arginine to vary microbial responses and keep other soil properties constant. The evolution of CO2 during 1 and 3 days following rewetting of dried soil was highly related to CO2 evolution during 10 days following...

aim : the aim of this survey was to compare four dna extraction methods from iranian sheep strain e.granulosus isolates. background : cystic echinococcosis (ce) caused by the metacestode of the dog tapeworm echinococcus spp., is a global zoonotic infection which is economically important and constitutes a major threat to public health in many countries. strains characterization is essential for...

AIMS This multicentre, randomized trial compared three strategies of AF ablation: ablation of complex fractionated electrograms (CFE) alone, pulmonary vein isolation (PVI) alone, and combined PVI + CFE ablation, using standardized automated mapping software. METHODS AND RESULTS Patients with drug-refractory, high-burden paroxysmal (episodes >6 h, >4 in 6 months) or persistent atrial fibrillat...

Real-time PCR analysis of bacterial DNA isolated from faecal specimens has become increasingly used for the quantification of indigenous intestinal microbiota. The success of such analysis requires effective methods for the extraction of faecal bacterial DNA. Three extraction methods were assessed for their effectiveness in extracting Escherichia coli and Enterococcus spp. bacterial DNA from hu...

The effects of water potential on the cellular compositions of a soil bacterium and a fungus were examined by growing the organisms in media with various KCl concentrations. In media containing up to 1 M KCl, C/N ratios in Aspergillus flavus increased significantly, while those for a Pseudomonas sp. did not. For both organisms, the proportions of cellular C and N in cytoplasm increased by a fac...

Characterization of acoustic emission (AE) signals in loaded materials can reveal structural damage and consequently provide early warnings about product failures. Therefore, extraction the most informative features from AE is an important part characterization process. This study considers obtained bending experiments for carbon fiber epoxy (CFE) glass (GFE) composites. The research focused on...
