Mangrove Bacterial Diversity and the Impact of Oil Contamination Revealed by Pyrosequencing: Bacterial Proxies for Oil Pollution
The use of sequences of the selected genera as proxies for oil pollution, using qPCR assessments, are suggested to permit the evaluation of the level of perturbance of mangroves, being useful in field monitoring.
Bacterial diversity in rhizosphere soil from Antarctic vascular plants of Admiralty Bay, maritime Antarctica
To the best of the knowledge, this is the first major bacterial sequencing effort of this kind of soil, and it revealed more than expected diversity within these rhizospheres of both maritime Antarctica vascular plants in Admiralty Bay, King George Island, which is part of the South Shetlands archipelago.
Assessment of the microbial diversity of Brazilian kefir grains by PCR-DGGE and pyrosequencing analysis.

Kefir and its constituents have antimicrobial, antitumor, anticarcinogenic and immunomodulatory activity and also improve lactose digestion, among others, and the status of a natural probiotic is designated as the 21th century yoghurt.
Bacterial polycyclic aromatic hydrocarbon ring-hydroxylating dioxygenases (PAH-RHD) encoding genes in different soils from King George Bay, Antarctic Peninsula
Bioremediation of Mangroves Impacted by Petroleum
It is suggested that measuring plant recuperation should be considered with reduction in polycyclic aromatic hydrocarbons (PAHs), and in some environments, such as mangroves, bioremediation may be the most appropriate approach for cleanup.
Microbiological and chemical characteristics of Brazilian kefir during fermentation and storage processes.
From fermentation to final storage, the pH, lactose content and citric acid of the kefir beverage decreased, followed by an increase in the concentrations of glucose, galactose, ethanol, and lactic, acetic, butyric, and propionic acids.

The term BMC (Beneficial Microorganisms for Corals) is proposed to define (specific) symbionts that promote coral health and the potential mechanisms of the effects of BMC on corals are proposed, suggesting strategies for the use of this knowledge to manipulate the microbiome, reversing dysbiosis to restore and protect coral reefs.
Climate change affects key nitrogen-fixing bacterial populations on coral reefs
The effects of increased seawater temperature on bacteria able to fix nitrogen (diazotrophs) that live in association with the mussid coral Mussismilia harttii were investigated and consistent increases in diazotrophic abundances and diversities were found at increased temperatures.

Using the rpoB gene offers a better alternative to the commonly used 16S rRNA gene for microbial community analyses based on DGGE because the gene for the beta subunit of the RNA polymerase, rPoB, is a single copy gene unlike 16SrDNA.
