Differential molecular responses of rapeseed cotyledons to light and dark reveal metabolic adaptations towards autotrophy establishment

Frontiers in Plant Science, 2016
Photosynthesis competent autotrophy should be established during the postgerminative stage of plant growth. Among the multiple factors, light plays a decisive role in the switch from heterotrophic to autotrophic growth. Under dark condition, the rapeseed

On the pathways feeding the H₂ production process in nutrient-replete, hypoxic conditions : commentary on the article 'Low oxygen levels contribute to improve photohydrogen production in mixotrophic non-stressed Chlamydomonas cultures', by Jurado-Oller et al., Biotechnology for Biofuels, published September 7, 2015; 8:149 [PDF]

, 2017
Background: Under low O-2 concentration ( hypoxia) and low light, Chlamydomonas cells can produce H-2 gas in nutrient-replete conditions. This process is hindered by the presence of O-2, which inactivates the [FeFe]-hydrogenase enzyme responsible for H-2

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Processes controlling carbon cycling in Antarctic glacier surface ecosystems [PDF]

, 2016
Glacier surface ecosystems, including cryoconite holes and cryolakes, are significant contributors to regional carbon cycles. Incubation experiments to determine the net production (NEP) of organic matter in cryoconite typically have durations of 6-24 ...

Nutrient availability modulates impacts of short‐term shifts in temperature and grazing on phytoplankton composition and size structure

Limnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract The significant contribution of phytoplankton to global primary production is regulated by several abiotic and biotic factors, which are often difficult to account for in natural systems. To address these challenges, we perturbed a summer plankton community from Narragansett Bay, Rhode Island, USA, by manipulating the temperature and nutrient ...

Interaction between CO2-consuming autotrophy and CO2-producing heterotrophy in non-axenic phototrophic biofilms.

PLoS ONE, 2021
As the effects of climate change become increasingly evident, the need for effective CO2 management is clear. Microalgae are well-suited for CO2 sequestration, given their ability to rapidly uptake and fix CO2.

Revealing Seasonal Patterns and Metabolism of Microbial Plankton in a Productive Coastal Upwelling System

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

Obligate autotrophy at the thermodynamic limit of life in a new acetogenic bacterium

Frontiers in Microbiology, 2023
One of the important current issues of bioenergetics is the establishment of the thermodynamic limits of life. There is still no final understanding of what is the minimum value of the energy yield of a reaction that is sufficient to be used by an ...

Predicting plankton net community production in the Atlantic Ocean [PDF]

, 2009
We present, test and implement two contrasting models to predict euphotic zone net community production (NCP), which are based on 14C primary production (PO14CP) to NCP relationships over two latitudinal (ca.

Biological Conversion of Formate to Organic Compounds: Toward a Sustainable Formate Bioeconomy

Carbon Energy, Volume 8, Issue 1, January 2026.
Formate bioconversion plays a crucial role in achieving renewable resource utilization and sustainable development. To tap its full potential, it is important to identify the most appropriate microbial hosts for incorporating formate into building blocks, design the most promising metabolic pathways for transmitting formate into central carbon ...
