Bacteria in the surface sediments of a subtropical mangrove habitat were investigated using a cultivation-independent molecular approach. Phylogenetic analysis of nearly full-length 16S rRNA genes revealed a diversity of sequences that were mostly novel. Members from the five subdivisions of the Proteobacteria were detected, and they collectively represented the majority (67%) of the clone library. Sequence types affiliated with the Gammaproteobacteria constituted the largest portion (29%) of… 

The bacterial diversity in a Brazilian non-disturbed mangrove sediment

The clustering and redundancy analysis (RDA) based on DGGE were used to determine factors that modulate the diversity of bacterial communities in mangroves, such as depth, seasonal fluctuations, and locations over a transect area from the sea to the land.

Culture independent molecular analysis of bacterial communities in the mangrove sediment of Sundarban, India

A probable hydrocarbon and oil contamination in this sediment is indicated and a number of clones were identified that have shown similarity with bacterial clones or isolates responsible for the maintenance of the S-cycle in the saline environment.

There is abundant microbial diversity and a large amount of unknown microbial resources in mangrove wetland ecological system, which could have a very important potential, and so there should be more research to explore and utilize these microbial and functional gene resources inMangrove wetlands ecological system.

Bacterial diversity in relatively pristine and anthropogenically-influenced mangrove ecosystems (Goa, India)

It is hypothesized that availability of extraneously-derived anthropogenic substrates could act as a stimulatant but not a deterrent to promote higher bacterial diversity at Divar with the possibility of Gammaproteobacteria contributing to modulating excess nitrate.

Microbial diversity of mangrove sediment in Shenzhen Bay and gene cloning, characterization of an isolated phytase-producing strain of SPC09 B. cereus

The cloning, characterization, and activity of a novel phytase isolated from a mangrove system is reported on, which showed the highest phosphorus solubilizing ability among the isolated strains.

Diversity and identification of methanogenic archaea and sulphate-reducing bacteria in sediments from a pristine tropical mangrove

The results show that these two guilds co-exist in these mangrove sediments and indicate important roles for these organisms in nutrient cycling within this ecosystem.

Illumina Sequencing of 16S rRNA Tag Revealed Spatial Variations of Bacterial Communities in a Mangrove Wetland

The bulk sediment inside the mature mangrove forest had the highest bacterial α-diversity, while the mudflat sediment without vegetation had the lowest, and the comparison of β-d diversity using principal component analysis and principal coordinate analysis with UniFrac metrics both showed that the spatial effects on bacterial communities were significant.


Microorganisms play important roles in nutrient cycling in mangrove ecosystems and knowledge on the plant/microorganism association is essential to better understand the functioning of this

Comparison of bacterial diversity from two mangrove ecosystems from India through metagenomic sequencing




High Bacterial Diversity in Permanently Cold Marine Sediments

The total diversity assessed by 16S rDNA analysis was very high in these permanently cold sediments and was only partially revealed by screening of 353 clones, suggesting a predominance of sequences related to bacteria of the sulfur cycle.

Prokaryotic Diversity in Zostera noltii-Colonized Marine Sediments

ABSTRACT The diversity of microorganisms present in a sediment colonized by the phanerogam Zostera noltii has been analyzed. Microbial DNA was extracted and used for constructing two 16S rDNA clone

Bacterial diversity in deep-sea sediments from different depths

A large number of cloned sequences in this study showed very low identity to known sequences, which may represent communities of as-yet-uncultivated microorganisms in the sediments.

Microbial Diversity in a Hydrocarbon- and Chlorinated-Solvent-Contaminated Aquifer Undergoing Intrinsic Bioremediation

It is hypothesized that the terminal step of hydrocarbon degradation in the methanogenic zone of the aquifer is aceticlastic methanogenesis and that the microorganisms represented by these two sequence types occur in syntrophic association.

Cultivation and Growth Characteristics of a Diverse Group of Oligotrophic Marine Gammaproteobacteria

This cultivation study revealed that sporadically detected Gammaproteobacteria gene clones from seawater are part of a phylogenetically diverse constellation of organisms mainly composed of oligotrophic and ultramicrobial lineages that are culturable under specific cultivation conditions.

Phylogenetic diversity of Archaea in prawn farm sediment

The selective dispersal of the archaeal population indicates that their ecological niches are associated with environmental characteristics and would be significant in the phylogenetic study of Archaea.

Diversity and vertical distribution of cultured and uncultured Deltaproteobacteria in an intertidal mud flat of the Wadden Sea.

The combination of FISH with catalysed reporter deposition (CARD-FISH) significantly enhanced the detection of selected subgroups of Deltaproteobacteria, particularly in deeper sediment layers, and suggested specific functional roles for the isolates.

Accelerated Sulfur Cycle in Coastal Marine Sediment beneath Areas of Intensive Shellfish Aquaculture

Prokaryotes in marine sediments taken from two neighboring semienclosed bays at the Sanriku coast in Japan were investigated by the culture-independent molecular phylogenetic approach coupled with chemical and activity analyses, hypothesizing that sulfate-reducing and sulfur-oxidizing bacteria have become abundant in the Yamada sediment.

Quantitative Molecular Analysis of the Microbial Community in Marine Arctic Sediments (Svalbard)

The hypothesis that δ-proteobacterial sulfate-reducing bacteria and members of the Cytophaga-Flavobacterium cluster are indigenous to the anoxic zones of marine sediments is supported.

Phylogenetic analysis of the bacterial communities in marine sediments

The analysis of clonal representives in the first report using molecular techniques to determine the phylogenetic composition of the (eu)bacterial community present in coastal marine sediments showed that the surficial sediments in Eagle Harbor contained a phylogenetically diverse population of organisms from the Bacteria domain.
