Bacterial diversity in primary infected root canals of a Chinese cohort: analysis of 16 S rDNA sequencing

BMC Oral Health, 2023
Purpose To characterize the bacterial community in the primarily infected root canals. Methods A total of 13 samples were collected from the primarily infected root canals. 16 S rDNA sequencing was performed to define bacterial community.

Soil bacterial community responses to short-term grazing exclusion in a degraded alpine shrubland – grassland ecotone

Ecological Indicators, 2021
Grazing exclusion by fencing is a common and effective grassland management strategy for degraded grassland restoration. Soil bacteria, the most important decomposers of soil organic matter, is the linkage between plant and soil.

Diversity and dynamics of bacterial and fungal communities in cider for distillation

International Journal of Food Microbiology, 2021
Bacterial and fungal population dynamics in cider for distillation have so far been explored by culture-dependant methods. Cider for distillation can be produced by the spontaneous fermentation of apples that do not undergo any intervention during the process.

Diversity, structure and sources of bacterial communities in earthworm cocoons [PDF]

Scientific Reports, 2018
AbstractAnimals start interactions with the bacteria that will constitute their microbiomes at embryonic stage. After mating, earthworms produce cocoons externally which will be colonized with bacteria from their parents and the environment. Due to the key role bacterial symbionts play on earthworm fitness, it is important to study bacterial ...

Canopy and Understory Nitrogen Addition Alters Organic Soil Bacterial Communities but Not Fungal Communities in a Temperate Forest

Frontiers in Microbiology, 2022
Atmospheric nitrogen (N) deposition is known to alter soil microbial communities, but how canopy and understory N addition affects soil bacterial and fungal communities in different soil layers remains poorly understood.

Bacteria in heavy metal contaminated soil: diversity, tolerance and use in remediation [PDF]

, 2010
The objectives of this project were to determine the bacterial diversity in a heavily contaminated metal region of Portugal. Both traditional and molecular based methods were used to identify tolerant strains and species. The most tolerant species were

PCR biases distort bacterial and archaeal community structure in pyrosequencing datasets [PDF]

, 2012
As 16S rRNA gene targeted massively parallel sequencing has become a common tool for microbial diversity investigations, numerous advances have been made to minimize the influence of sequencing and chimeric PCR artifacts through rigorous quality control ...

Diversity and enterotype in gut bacterial community of adults in Taiwan [PDF]

BMC Genomics, 2017
Gastrointestinal microbiota, particularly gut microbiota, is associated with human health. The biodiversity of gut microbiota is affected by ethnicities and environmental factors such as dietary habits or medicine intake, and three enterotypes of the human gut microbiome were announced in 2011.
