A ‘Genome‐First’ Framework for Next‐Generation Bioinputs: From Functional Mining to Rational Synthetic Microbial Communities

Environmental Microbiology, Volume 28, Issue 5, May 2026.
I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

Environmental forcing of nitrogen fixation in the eastern tropical and sub-tropical North Atlantic Ocean. [PDF]

PLoS ONE, 2011
During the winter of 2006 we measured nifH gene abundances, dinitrogen (N(2)) fixation rates and carbon fixation rates in the eastern tropical and sub-tropical North Atlantic Ocean.

Activity and interactions of methane seep microorganisms assessed by parallel transcription and FISH-NanoSIMS analyses [PDF]

, 2015
To characterize the activity and interactions of methanotrophic archaea (ANME) and Deltaproteobacteria at a methane-seeping mud volcano, we used two complimentary measures of microbial activity: a community-level analysis of the transcription of four ...

Ecological Patterns of nifH Genes in Four Terrestrial Climatic Zones Explored with Targeted Metagenomics Using FrameBot, a New Informatics Tool

mBio, 2013
Biological nitrogen fixation is an important component of sustainable soil fertility and a key component of the nitrogen cycle. We used targeted metagenomics to study the nitrogen fixation-capable terrestrial bacterial community by targeting the gene for

Seasonal nitrate drawdown transitions lake ecosystems from phosphorus to nitrogen deficiency in annual cycles

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups

Frontiers in Microbiology, 2017
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

An open reading frame upstream from the nifH gene of Klebsiella pneumoniae [PDF]

, 1983
An open reading frame upstream from nifHDK operon of Klebsiella pneumoniae had been described. The orientation of this open reading frame is opposite to that of nifHDK and sequence homology was found between the open reading frame promoter and the ...

Intercalation-enhanced electric polarization and chain formation of nano-layered particles

, 2005
Microscopy observations show that suspensions of synthetic and natural nano-layered smectite clay particles submitted to a strong external electric field undergo a fast and extended structuring.
