Use and detection of a vitamin B1 degradation product yields new views of the marine B1 cycle and plankton metabolite exchange
Paerl, R. W., Curtis, N. P., Bittner, M. J., Cohn, M. R., Gifford, S. M., Bannon, C. C., … Bertrand, E. M. (2023, June 28). MBIO, Vol. 6.
author keywords: marine microbiology; vitamin; thiamin; LC; MS; phytoplankton; bacterioplankton; vitamin B1
TL;DR:
Results of this collaborative study newly show that a vitamin B1 degradation product, N-formyl-4-amino-5-aminomethyl-2-methylpyrimidine (FAMP), can be used by diverse marine microbes (bacteria and phytoplankton) to meet their vitamin B 1 demands instead of B1 and that FAMP occurs in the surface ocean.

Exchange of Vitamin B-1 and Its Biosynthesis Intermediates Shapes the Composition of Synthetic Microbial Cocultures and Reveals Complexities of Nutrient Sharing
JOURNAL OF BACTERIOLOGY, 204(4).
author keywords: HMP; nutrient exchange; synthetic microbial coculture; thiamin; thiazole; vitamin B-1
MeSH headings : Coculture Techniques; Escherichia coli / genetics; Escherichia coli / metabolism; Nutrients; Thiamine; Thiazoles / metabolism; Vitamins / metabolism
TL;DR:
The exchange of vitamin B1 (thiamin) and its intermediates between microbes within synthetic cocultures of Escherichia coli and Vibrio anguillarum revealed that there exist specific patterns for thiamin metabolism and exchange among these microbes and underscores the importance of the exchange of essential metabolites as a defining factor in building and modulating synthetic or natural microbial communities.

Key Knowledge Gaps to Fill at the Cell-To-Ecosystem Level in Marine B-Vitamin Cycling
FRONTIERS IN MARINE SCIENCE, 9.
author keywords: nutrient cycling; marine plankton; B-vitamin; vitamin B12; vitamin B1; microbial interactions; cross-feeding; auxotrophy
TL;DR:
It is argued that significant advances in understanding of the impact of B-vitamin exchange and cycling on marine community structure and biogeochemistry can be made by focusing on unknowns related to the ‘in’s and out’ of B’vitamin transport, exchange between plankton, and ecosystem scale processing/transformation ofB-vitamins.

Carboxythiazole is a key microbial nutrient currency and critical component of thiamin biosynthesis
Scientific Reports, 8(1).
MeSH headings : Animals; Arabidopsis / metabolism; Arabidopsis Proteins / metabolism; Cell Line; Escherichia coli / metabolism; Mice; Nutrients / metabolism; Phytoplankton / metabolism; Thiamine / biosynthesis; Thiazoles / metabolism
TL;DR:
It is demonstrated that 5-(2-hydroxyethyl)-4-methyl-1,3-thiazole-2-carboxylic acid (cHET) is a useful in vivo B1 precursor for representatives of ubiquitous marine picoeukaryotic phytoplankton and Escherichia coli – drawing attention to cHET as a valuable exogenous micronutrient for microorganisms with ecological, industrial, and biomedical value.

Diazotrophs and N-2-Fixation Associated With Particles in Coastal Estuarine Waters
FRONTIERS IN MICROBIOLOGY, 9.
author keywords: diazotrophs; nitrogen fixation; marine particles; nifH; estuary
TL;DR:
It is indicated that resuspension of sediment material can elevate pelagic N2-fixation, and it is shown that diverse natural diazotrophs can colonize artificial surfaces, but colonization by “pioneer” bacterioplankton that more rapidly associate with surfaces appears to be a prerequisite.

Filtration via Conventional Glass Fiber Filters in 15N2 Tracer Assays Fails to Capture All Nitrogen-Fixing Prokaryotes
Frontiers in Marine Science, 5.
author keywords: oceanic nitrogen fixation; diazotrophs; cyanobacteria; glass fiber filter; bias; filtration
TL;DR:
Using Illumina sequencing of nitrogenase (nifH) gene amplicons, it is shown that diazotroph communities can markedly differ between bulk water and filtrates from GF/F and Advantec filtrations, suggesting that different d Diazotrophs can pass through the filter types.

Variation in Synechococcus sp. CC9311 narB mRNA abundance relative to changes in light, nitrogen growth conditions and nitrate assimilation.
Journal of Phycology, 48(4), 1028–1039.
author keywords: diel light; irradiance; mRNA; narB; nitrate assimilation; nitrate reductase; qPCR; Synechococcus; transcript abundance
TL;DR:
Environmental sampling for narB transcripts should consider time, irradiance, and the growth status of cells to ecologically interpret narB transcript abundances, as changes in narB mRNA levels in nitrogen‐deprived CC9311 cultures following nitrate amendment were distinct from cultures grown solely on nitrate.
