Mixotrophy in marine picocyanobacteria: use of organic compounds by Prochlorococcus and Synechococcus [PDF]

, 2020
Marine picocyanobacteria of the Prochlorococcus and Synechococcus genera have been longtime considered as autotrophic organisms. However, compelling evidence published over the last 15 years shows that these organisms can use different organic compounds ...

Forces Shaping Diversity of Hydrogen Peroxide Detoxification Potential in Ocean Microbial Ecosystems

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Marine microbes which lack catalases, like Prochlorococcus, depend on ‘helpers’, like catalase‐positive Alteromonas, for hydrogen peroxide detoxification. Our results indicate diverse and distinct distributions of catalases (katG, katE and manganese catalase) among community members.

Ecological and genomic features of two widespread freshwater picocyanobacteria [PDF]

Environmental Microbiology, 2018
Summary We present two genomes of widespread freshwater picocyanobacteria isolated by extinction dilution from a Spanish oligotrophic reservoir. Based on microscopy and genomic properties, both picocyanobacteria were tentatively designated Synechococcus lacustris Tous ...

Nitrogen and phosphorus uptake kinetics in cultures of two novel picoplankton groups responsible for a recent bloom event in a subtropical estuary (Indian River Lagoon, Florida)

Frontiers in Marine Science
IntroductionSuccessful management and mitigation of harmful algal blooms (HABs) requires an in-depth understanding of the physiology and nutrient utilization of the organisms responsible. We explored the preference of various nitrogen (N) and phosphorus (

Seasonal expression of the picocyanobacterial phosphonate transporter gene phnD in the Sargasso Sea

Frontiers in Microbiology, 2010
In phosphorus-limited marine environments, picocyanobacteria (Synechococcus and Prochlorococcus spp.) can hydrolyze naturally occurring phosphonates as a P source.

Novel functional insights into a modified sugar-binding protein from Synechococcus MITS9220

Scientific Reports, 2022
Paradigms of metabolic strategies employed by photoautotrophic marine picocyanobacteria have been challenged in recent years. Based on genomic annotations, picocyanobacteria are predicted to assimilate organic nutrients via ATP-binding cassette importers,

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Mechanisms of Calcite Precipitation by Picocyanobacteria

, 2006
Picocyanobacteria play an important role in the process of calcite precipitation especially in oligotrophic lakes. The nucleation mechanisms of calcite on the cyanobacterial cell surface, however, remain controversial. Thus, it was the main objective of this thesis to clarify these mechanisms of calcite nucleation with special focus on differentiating ...

Photosynthetic Pigments Changes of Three Phenotypes of Picocyanobacteria Synechococcus sp. under Different Light and Temperature Conditions

Cells, 2020
It is estimated that the genus Synechococcus is responsible for about 17% of net primary production in the Global Ocean. Blooms of these organisms are observed in tropical, subtropical and even temperate zones, and they have been recorded recently even ...
