A lithotrophic microbial fuel cell operated with pseudomonads‐dominated iron‐oxidizing bacteria enriched at the anode
Microbial Biotechnology - Tập 8 Số 3 - Trang 579-589 - 2015
SummaryIn this study, we attempted to enrich neutrophilic iron bacteria in a
microbial fuel cell (MFC)‐type reactor in order to develop a lithotrophic MFC
system that can utilize ferrous iron as an inorganic electron donor and operate
at neutral pHs. Electrical currents were steadily generated at an average level
of 0.6 mA (or 0.024 mA cm–2 of membrane area) in reactors initially inoculated
with m...
Meta‐analysis generates and prioritizes hypotheses for translational microbiome research
Microbial Biotechnology - Tập 11 Số 2 - Trang 273-276 - 2018
Black soldier fly larvae (Hermetia illucens) strengthen the metabolic function of food waste biodegradation by gut microbiome
Microbial Biotechnology - Tập 12 Số 3 - Trang 528-543 - 2019
SummaryVermicomposting using black soldier fly (BSF) larvae (Hermetia illucens)
has gradually become a promising biotechnology for waste management, but
knowledge about the larvae gut microbiome is sparse. In this study, 16S rRNA
sequencing, SourceTracker, and network analysis were leveraged to decipher the
influence of larvae gut microbiome on food waste (FW) biodegradation. The
microbial communi...
AnUstilago maydischassis for itaconic acid production without by‐products
Microbial Biotechnology - Tập 13 Số 2 - Trang 350-362 - 2020
SummaryUstilago maydisis a promising yeast for the production of a range of
valuable metabolites, including itaconate, malate, glycolipids and
triacylglycerols. However, wild‐type strains generally produce a potpourri of
all of these metabolites, which hinders efficient production of single target
chemicals. In this study, the diverse by‐product spectrum ofU. maydiswas reduced
through strain engin...
Effect of inoculation with a microbial consortium that degrades organic acids on the composting efficiency of food waste
Microbial Biotechnology - Tập 11 Số 6 - Trang 1124-1136 - 2018
SummaryIn order to overcome the excessive acidification problem, a microbial
consortium for the degradation of organic acids (MCDOA), which acts
synergistically in degrading organic acids, was developed and used as an
inoculum to improve the efficiency of food waste composting. MCDOA could
eliminate the initial lag phase of the pile temperature rise because of
excessive acidification and effective...
Molecular characterization of a microbial consortium involved in methane oxidation coupled to denitrification under micro‐aerobic conditions
Microbial Biotechnology - Tập 7 Số 1 - Trang 64-76 - 2014
SummaryMethane can be used as an alternative carbon source in biological
denitrification because it is nontoxic, widely available and relatively
inexpensive. A microbial consortium involved in methane oxidation coupled to
denitrification (MOD) was enriched with nitrite and nitrate as electron
acceptors under micro‐aerobic conditions. The 16S rRNA gene combined with pmoA
phylogeny of methanotrophs ...
Co‐occurrence of antibiotic, biocide, and heavy metal resistance genes in bacteria from metal and radionuclide contaminated soils at the Savannah River Site
Microbial Biotechnology - Tập 13 Số 4 - Trang 1179-1200 - 2020
SummaryContaminants such as heavy metals may contribute to the dissemination of
antimicrobial resistance (AMR) by enriching resistance gene determinants via
co‐selection mechanisms. In the present study, a survey was performed on soils
collected from four areas at the Savannah River Site (SRS), South Carolina, USA,
with varying contaminant profiles: relatively pristine (Upper Three Runs), heavy
me...
Comparative genome‐wide analysis of small RNAs of major Gram‐positive pathogens: from identification to application
Microbial Biotechnology - Tập 3 Số 6 - Trang 658-676 - 2010
SummaryIn the recent years, the number of drug‐ and multi‐drug‐resistant
microbial strains has increased rapidly. Therefore, the need to identify
innovative approaches for development of novel anti‐infectives and new
therapeutic targets is of high priority in global health care. The detection of
small RNAs (sRNAs) in bacteria has attracted considerable attention as an
emerging class of new gene ex...
Membrane biofilm development improves COD removal in anaerobic membrane bioreactor wastewater treatment
Microbial Biotechnology - Tập 8 Số 5 - Trang 883-894 - 2015
SummaryMembrane biofilm development was evaluated to improve psychrophilic
(15°C) anaerobic membrane bioreactor (AnMBR) treatment of domestic wastewater.
An AnMBR containing three replicate submerged membrane housings with separate
permeate collection was operated at three levels of membrane fouling by
independently controlling biogas sparging for each membrane unit. High membrane
fouling signific...
Nitrite production by ammonia‐oxidizing bacteria mediates chloramine decay and resistance in a mixed‐species community
Microbial Biotechnology - Tập 13 Số 6 - Trang 1847-1859 - 2020
SummaryAs water distribution centres increasingly switch to using chloramine to
disinfect drinking water, it is of paramount importance to determine the
interactions of chloramine with potential biological contaminants, such as
bacterial biofilms, that are found in these systems. For example,
ammonia‐oxidizing bacteria (AOB) are known to accelerate the decay of chloramine
in drinking water systems...
