Carbon Assimilation by the Picoplanktonic Community Inhabiting the Secondary Chlorophyll Maximum of the Anoxic Marine Zones of the Eastern Tropical North and South Pacific

open access: yesFrontiers in Marine Science, 2022
Anoxic marine zones (AMZs) constitute pelagic systems distinguished from the oxygen minimum zones (OMZs) by the complete absence of detectable oxygen and the accumulation of nitrite in mid-waters.

Metabolomic Study of Heterotrophically Grown Chlorella sp. Isolated from Wastewater in Northern Sweden

open access: yesMolecules, 2021
There are numerous strains of Chlorella with a corresponding variety of metabolic pathways. A strain we previously isolated from wastewater in northern Sweden can grow heterotrophically as well as autotrophically in light and has higher lipid contents ...

Concomitant knockout of target and transporter genes in filamentous fungi by genome co‐editing

open access: yesMicrobiologyOpen, 2022
In most countries, genetically modified microorganisms are not approved for use for fermentation in the food industry. Therefore, random mutagenesis and subsequent screening are performed to improve the productivities of valuable metabolites and enzymes ...

Red Light Variation an Effective Alternative to Regulate Biomass and Lipid Profiles in Phaeodactylum tricornutum

open access: yesApplied Sciences, 2020
Marine water diatom Phaeodactylum tricornutum is a photosynthetic organism that is known to respond to the changing light environment and adapt to different temperatures to prevent photoinhibition and maintain its metabolic functions.

(S)-3-Hydroxybutyryl-CoA Dehydrogenase From the Autotrophic 3-Hydroxypropionate/4-Hydroxybutyrate Cycle in Nitrosopumilus maritimus

open access: yesFrontiers in Microbiology, 2021
Ammonia-oxidizing archaea of the phylum Thaumarchaeota are among the most abundant organisms that exert primary control of oceanic and soil nitrification and are responsible for a large part of dark ocean primary production.

Nutrient budgets (C, N and P) and trophic dynamicsof a Brazilian tropical estuary: Barra das Jangadas

open access: yesAnais da Academia Brasileira de Ciências, 2011
This paper focuses on the nutrient dynamics of a tropical estuary on the northeastern Brazilian coast, studied using the LOICZ biogeochemical budgeting protocol. We describe the methodology and assumptions underlying this model.

Relative Diazotroph Abundance in Symbiotic Red Sea Corals Decreases With Water Depth

open access: yesFrontiers in Marine Science, 2019
Microbial dinitrogen (N2) fixation (diazotrophy) is a trait critical for coral holobiont functioning. The contribution of N2 fixation to holobiont nitrogen (N) supply likely depends on the ecological niche of the coral holobiont.

The response of the Mediterranean gorgonian Eunicella singularis to thermal stress is independent of its nutritional regime. [PDF]

open access: yesPLoS ONE, 2013
Over the last few decades, sessile benthic organisms from the Mediterranean Sea have suffered from the global warming of the world's oceans, and several mass mortality events were observed during warm summers.
