Pharmaceutical exposure changed antibiotic resistance genes and bacterial communities in soil-surface- and overhead-irrigated greenhouse lettuce

Environment International, 2019
New classes of emerging contaminants such as pharmaceuticals, antibiotic resistant bacteria (ARB), and antibiotic resistance genes (ARGs) have received increasing attention due to rapid increases of their abundance in agroecosystems.

Identification of Aerobic ETBE‐Degrading Microorganisms in Groundwater Using Stable Isotope Probing

Groundwater Monitoring &Remediation, Volume 44, Issue 4, Page 92-103, Fall 2024.
Abstract A limited number of microorganisms have been identified with the capability to degrade ethyl tert‐butyl ether (ETBE) in the environment. Knowledge of the identity and distribution of ETBE‐degrading microorganisms is important for the implementation of management measures such as natural attenuation and bioremediation at ETBE‐release sites.

Ocean acidification shows negligible impacts on high-latitude bacterial community structure in coastal pelagic mesocosms [PDF]

, 2012
The impact of ocean acidification and carbonation on microbial community structure was assessed during a large-scale in situ costal pelagic mesocosm study, included as part of the EPOCA 2010 Arctic campaign.

Phaeocystis globosa and diatom blooms promote distinct bacterial communities and associations in a coastal ecosystem

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
Bacteria and phytoplankton succession and their putative interactions were investigated in a coastal ecosystem across multiple years. During winter, in the presence of a diverse diatom community, bacteria were associated with, and between, all phytoplankton.

Comparative Molecular Microbial Ecology of the Spring Haptophyte Bloom in a Greenland Arctic Oligosaline Lake [PDF]

, 2012
The Arctic is highly sensitive to increasing global temperatures and is projected to experience dramatic ecological shifts in the next few decades. Oligosaline lakes are common in arctic regions where evaporation surpasses precipitation, however these ...

Effect of acetate and methanol on the kinetics of total dissolved selenium removal in a chemostat

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 6, Page 1325-1341, June 2024.
Abstract BACKGROUND Carbon (C) source consumption in industrial bioreactors removing soluble selenium (Se) contributes to the operating cost and can influence the rate of removal. This study used a laboratory chemostat to investigate the dependency of the rate of dissolved Se removal on the concentration of acetate and methanol, two C sources used in ...

Host Ecology Rather Than Host Phylogeny Drives Amphibian Skin Microbial Community Structure in the Biodiversity Hotspot of Madagascar

Frontiers in Microbiology, 2017
Host-associated microbiotas of vertebrates are diverse and complex communities that contribute to host health. In particular, for amphibians, cutaneous microbial communities likely play a significant role in pathogen defense; however, our ecological ...

Methanol excretion by Methylomonas methanica is induced by the supernatant of a methanotrophic consortium

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 6, Page 1356-1363, June 2024.
Abstract BACKGROUND Methanotrophs play an important role in mitigating methane (CH4) emissions in ecosystems. They closely interact with other microorganisms forming communities where the cross‐feeding of metabolites, presumably methanol (MeOH), is essential for the growth and activity of non‐methanotrophs. The experiments in this study were focused on

Oil type and temperature dependent biodegradation dynamics - Combining chemical and microbial community data through multivariate analysis

BMC Microbiology, 2018
Background This study investigates a comparative multivariate approach for studying the biodegradation of chemically dispersed oil. The rationale for this approach lies in the inherent complexity of the data and challenges associated with comparing ...
