High protists diversity in the plankton of sulfurous lakes and lagoons examined by 18s rRNA gene sequence analyses
Environmental Microbiology Reports - Tập 7 Số 6 - Trang 908-917 - 2015
SummaryDiversity of small protists was studied in sulfidic and anoxic (euxinic)
stratified karstic lakes and coastal lagoons by 18S rRNA gene analyses. We
hypothesized a major sulfide effect, reducing protist diversity and richness
with only a few specialized populations adapted to deal with low‐redox
conditions and high‐sulfide concentrations. However, genetic fingerprinting
suggested similar eco...
Functional genome mining and taxono‐genomics reveal eco‐physiological traits and species distinctiveness of aromatic‐degrading Pseudomonas bharatica sp. nov.
Environmental Microbiology Reports - Tập 14 Số 3 - Trang 464-474 - 2022
SummaryAssistive eco‐physiological traits are necessary for microbes to adapt
and colonize at polluted niches, enabling efficient clean‐up. To demarcate
species distinctiveness and eco‐physiological traits of aromatic compounds
metabolizing Pseudomonas sp. CSV86T (earlier identified as Pseudomonas putida),
an Indian isolate from a petrol station soil, comparative genome mining,
taxono‐genomic, and...
The C lermont E scherichia coli phylo‐typing method revisited: improvement of specificity and detection of new phylo‐groups
Environmental Microbiology Reports - Tập 5 Số 1 - Trang 58-65 - 2013
SummaryThere is extensive genetic substructure within the species Escherichia
coli. In 2000 a simple triplex PCR method was described by Clermont and
colleagues that enables an E. coli isolate to be assigned to one of the
phylo‐groups A, B1, B2 or D. The growing body of multi‐locus sequence data and
genome data for E. coli has refined our understanding of E. coli's phylo‐group
structure and eight ...
ddPCR applied on archived Continuous Plankton Recorder samples reveals long‐term occurrence of class 1 integrons and a sulphonamide resistance gene in marine plankton communities
Environmental Microbiology Reports - Tập 10 Số 4 - Trang 458-464 - 2018
SummaryAntibiotic resistance is a rising threat for human health. Although in
clinical settings and terrestrial environments the rise of antibiotic resistant
bacteria is well documented, their dissemination and spread in the marine
environment, covering almost two‐thirds of the Earth's surface, is still poorly
understood. In this study, the presence and abundance of sulphonamide resistance
gene (s...
Branchial nitrogen cycle symbionts can remove ammonia in fish gills
Environmental Microbiology Reports - Tập 8 Số 5 - Trang 590-594 - 2016
SummaryKnowledge of the mechanisms by which fish excrete their metabolic
nitrogenous waste and insights into nitrogen cycling in aquaculture systems is
of utmost importance to improve the sustainable commercial production of fish.
In fish, most nitrogenous waste is excreted via the gills as ammonia, a
potentially toxic nitrogenous compound. In this study; activity assays,
physiological experiments...
Climate change: a catalyst for global expansion of harmful cyanobacterial blooms
Environmental Microbiology Reports - Tập 1 Số 1 - Trang 27-37 - 2009
SummaryCyanobacteria are the Earth's oldest known oxygen‐evolving photosynthetic
microorganisms, and they have had major impacts on shaping our current
atmosphere and biosphere. Their long evolutionary history has enabled
cyanobacteria to develop survival strategies and persist as important primary
producers during numerous geochemical and climatic changes that have taken place
on Earth during the...
Subcellular localization of five singular WSC domain‐containing proteins and their roles in Beauveria bassiana responses to stress cues and metal ions
Environmental Microbiology Reports - Tập 8 Số 2 - Trang 295-304 - 2016
SummarySome model fungi have three or four proteins with each vectoring a single
cell Wall Stress‐responsive Component (WSC) domain at N‐terminus. In this study,
five proteins, each vectoring only a single WSC domain in N‐terminal, central or
even C‐terminal region, were found in Beauveria bassiana, a filamentous fungal
entomopathogen, and named Wsc1A–1E due to the domain singularity. Four of them...
Siderophore‐promoted dissolution of smectite by fluorescent P seudomonas
Environmental Microbiology Reports - Tập 6 Số 5 - Trang 459-467 - 2014
SummarySiderophores are organic chelators produced by microorganisms to fulfil
their iron requirements. Siderophore‐promoted dissolution of iron‐bearing
minerals has been clearly documented for some siderophores, but few studies have
addressed metabolizing siderophore‐producing bacteria. We investigated iron
acquisition from clays by fluorescent Pseudomonads, bacteria that are ubiquitous
in the en...
Local and regional factors influencing bacterial community assembly
Environmental Microbiology Reports - Tập 4 Số 1 - Trang 1-9 - 2012
SummaryThe classical view states that microbial biogeography is not affected by
dispersal barriers or historical events, but only influenced by the local
contemporary habitat conditions (species sorting). This has been challenged
during recent years by studies suggesting that also regional factors such as
mass effect, dispersal limitation and neutral assembly are important for the
composition of l...
Diversity and pathogenecity of Vibrio species in cultured bivalve molluscs
Environmental Microbiology Reports - Tập 2 Số 1 - Trang 34-43 - 2010
SummaryShellfish production is seriously affected by bacterial pathogens that
cause high losses in hatcheries and in the aquaculture sector. A number of
Vibrio species are considered important pathogens and have provoked severe
mortality outbreaks. The pathologies caused by vibrios in bivalves have been
described since the 1960s; however, over recent years, successive episodes of
high mortality ha...
