Circadian Rhythms in Cyanobacteria [PDF]

open access: yesMicrobiology and Molecular Biology Reviews, 2015
SUMMARY Life on earth is subject to daily and predictable fluctuations in light intensity, temperature, and humidity created by rotation of the earth. Circadian rhythms, generated by a circadian clock, control temporal programs of cellular physiology to facilitate adaptation to daily environmental changes.

Improving trans‐cinnamic acid production in a model cyanobacterium

open access: yesBiotechnology Progress, Volume 41, Issue 2, March/April 2025.
Abstract trans‐Cinnamic acid (tCA) is a precursor in the synthesis of many high‐value compounds with bio‐active qualities useful in applications like medicine, polymers, and cosmetics. Currently tCA is produced by industrial chemical synthesis from fossil fuels or cost‐prohibitive isolation from terrestrial plants.

Preparation of cyanobacteria-enhanced poly(vinyl)alcohol-based films with resistance to blue-violet light / red light and water.

open access: yesPLoS ONE, 2020
The harmful cyanobacteria blooms which usually form in spring and summer, cause global eutrophication of freshwater and coastal marine ecosystems. This study tried to utilize cyanobacteria as a raw material to produce biological poly(vinyl)alcohol-based ...

Super-Earths, M Dwarfs, and Photosynthetic Organisms: Habitability in the Lab [PDF]

open access: yesLife, 2021, 11, 10, 2021
In a few years, space telescopes will investigate our Galaxy to detect evidence of life, mainly by observing rocky planets. In the last decade, the observation of exoplanet atmospheres and the theoretical works on biosignature gasses have experienced a considerable acceleration.

Enhancement of D‐mannitol production by fine‐tuned expression of mannitol‐1‐phosphate dehydrogenase in Synechocystis sp. PCC6803

open access: yesBiotechnology Progress, EarlyView.
Abstract D‐Mannitol production was achieved in freshwater Synechocystis sp. PCC6803 via the heterologous expression of mannitol‐1‐phosphate dehydrogenase (mtlD) and mannitol‐1‐phosphatase (m1p) under control of the strong promoter Ptrc1. However, only 5.54 mg L−1 of mannitol was found extracellularly after 7 days of cultivation, likely due to ...

Genome-scale phylogenetic analysis finds extensive gene transfer among Fungi [PDF]

open access: yes, 2015
Although the role of lateral gene transfer is well recognized in the evolution of bacteria, it is generally assumed that it has had less influence among eukaryotes.

Selection of cyanobacteria over green algae in a photo-sequencing batch bioreactor fed with wastewater [PDF]

open access: yesarXiv, 2018
A strategy based on photo sequencing batch operation was used to select cyanobacteria over unsettled green algae in a wastewater treatment system, evaluating for the first time the effect of hydraulic regimes on nutritional dynamics and microorganisms competition. During 30 days of operation, an initial microalgae mixed consortia dominated by the green

Porous translucent electrodes enhance current generation from photosynthetic biofilms [PDF]

open access: yes, 2017
We tested the enhancement of electrical current generated from photosynthetically active bacteria by use of electrodes with porosity on the nano- and micrometer length-scale. For two cyanobacteria on structured indium-tin-oxide electrodes, current generation was increased by two orders of magnitude and the photo-response was substantially faster ...
