Bacterial Community Composition and Activity

1981
Microorganisms, particularly bacteria, constitute the largest numerical population in most aquatic environments and are often the most metabolically active aquatic organisms. The short generation time and great physiological capacity of bacteria as a group enable them to survive and flourish in environments that are inhospitable to other organisms ...

Composition of epiphytic bacterial communities differs on petals and leaves

Plant Biology, 2011
AbstractThe epiphytic bacterial communities colonising roots and leaves have been described for many plant species. In contrast, microbiologists have rarely considered flowers of naturally growing plants. We identified bacteria isolated from the surface of petals and leaves of two plant species, Saponaria officinalis (Caryophyllaceae) and Lotus ...

Composition of bacterial communities in municipal wastewater treatment plant

Science of The Total Environment, 2019
Efforts to understand the environmental and biological factors that influence the dynamics of microbial communities have received substantial attention in microbial ecology. In this study, Illumina MiSeq high-throughput sequencing technology was used to examine the microbial community structure of activated sludge in municipal wastewater treatment ...

Influence of Parity on the Colostrum Bacterial Community Composition in Holstein Cows

Indian Journal of Microbiology, 2022
The colostrum bacteriome of primiparous (P) and multiparous (M) Holstein cows was analysed by 16S rRNA sequencing. The species richness (Chao 1), diversity (Shannon and Simpson), and beta diversity did not differ between cow groups. The phyla Firmicutes, Tenericutes, Kiritimatiellaeota, and Fibrobacteres were more abundant in M cows, while ...

Bacterial community composition and function in sewage treatment systems

Current Opinion in Biotechnology, 2002
The application of modern molecular techniques has led to the identification, in situ quantification, and partial ecophysiological characterisation of bacteria responsible for bulking and foaming or for nutrient removal in sewage treatment systems. Unexpectedly, previously unrecognised, yet uncultured bacteria were demonstrated to catalyse nitrogen and

Diversity and Composition of Gut Bacterial Community in Giant Panda with Anorexia

Current Microbiology, 2021
The giant panda (GP) is the most precious animal in China. Gastrointestinal tract disease, especially associated with dysbiosis of gut microbiota, is the leading cause of death in GPs. Here, we performed 16S rRNA high-throughput sequencing to investigate the gut microbiota of GPs having symptoms of anorexia.

Flagellate Predation on a Bacterial Model Community: Interplay of Size-Selective Grazing, Specific Bacterial Cell Size, and Bacterial Community Composition

Applied and Environmental Microbiology, 1999
ABSTRACT The influence of grazing by the bacterivorous nanoflagellate Ochromonas sp. strain DS on the taxonomic and morphological structures of a complex bacterial community was studied in one-stage chemostat experiments.

Matrix composition and community structure analysis of a novel bacterial pyrite leaching community

Environmental Microbiology, 2009
Summary Here we describe a novel bacterial community that is embedded in a matrix of carbohydrates and bio/geochemical products of pyrite (FeS 2 ) oxidation. This community grows in stalactite‐like structures – snottites – on the ceiling of an abandoned pyrite mine at pH ...

THE ROLE OF ENVIRONMENTAL AND SPATIAL FACTORS FOR THE COMPOSITION OF AQUATIC BACTERIAL COMMUNITIES

Ecology, 2007
This study investigates the importance of local vs. spatial factors on bacterial community composition of 35 rock pools at the Baltic Sea coast. The pools were located in five distinct spatial clusters over a total scale of
