Polyphosphate phosphorus in the Great Lakes

Limnology and Oceanography Letters, Volume 9, Issue 5, Page 602-611, October 2024.
Abstract Polyphosphate (polyP) is important to phytoplankton ecology, but a unified view of its variability and roles in ecosystem‐scale phosphorus (P) cycling is lacking. We study polyP in the world's largest freshwater ecosystem, the Laurentian Great Lakes, covering pelagic to nearshore areas across a wide nutrient gradient.

Mapping of protein-protein interaction sites in the plant-type [2Fe-2S] ferredoxin. [PDF]

PLoS ONE, 2011
Knowing the manner of protein-protein interactions is vital for understanding biological events. The plant-type [2Fe-2S] ferredoxin (Fd), a well-known small iron-sulfur protein with low redox potential, partitions electrons to a variety of Fd-dependent ...

Nutritional evaluation of single-cell protein produced by Aphanothece microscopica Nägeli

Bioresource Technology, 2010
The aim of this research was to evaluate the nutritional characteristics of Aphanothece microscopica Nägeli microalgae developed in the effluent of parboiled rice. The biomass was biologically evaluated by rat growth, during 10 days for nitrogen balance studies and 28 days for blood analysis.

Colony‐forming and single‐cell picocyanobacteria nitrogen acquisition strategies and carbon fixation in the brackish Baltic Sea

Limnology and Oceanography, Volume 69, Issue 9, Page 1955-1969, September 2024.
Abstract Picocyanobacteria are widespread and globally significant primary producers. In brackish waters, picocyanobacterial populations are composed of diverse species with both single‐cell and colony‐forming lifestyles. Compared to their marine counterparts, brackish picocyanobacteria are less well characterized and the focus of research has been ...

Bacterial community and cyanotoxin gene distribution of the Winam Gulf, Lake Victoria, Kenya

Environmental Microbiology Reports, Volume 16, Issue 3, June 2024.
This work identified cyanobacterial community and cyanotoxin gene distribution in the Winam Gulf, Lake Victoria, Kenya. Cyanobacterial communities clustered in line with different areas of the Gulf, while cyanotoxin gene concentrations varied between the eastern and western regions.

Characterization of Nitrogen-Fixing Cyanobacterial Consortia Isolated from the Rhizosphere of Carica papaya

Agronomy
Nitrogen-fixing cyanobacterial consortia are an alternative to the indiscriminate use of chemical fertilizers that affect the environment, fix atmospheric nitrogen, and can therefore be used as plant growth promoters, synthesize various substances such ...

Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]

, 2019
Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Crocosphaera watsonii – A widespread nitrogen‐fixing unicellular marine cyanobacterium

Journal of Phycology, Volume 60, Issue 3, Page 604-620, June 2024.
Abstract Crocosphaera watsonii is a unicellular N2‐fixing (diazotrophic) cyanobacterium observed in tropical and subtropical oligotrophic oceans. As a diazotroph, it can be a source of bioavailable nitrogen (N) to the microbial community in N‐limited environments, and this may fuel primary production in the regions where it occurs.

MOLECULAR CHARACTERIZATION OF A GREEN ALGAE ISOLATE BY 16S rRNA IN IMPROVEMENT OF CAROTENOID PRODUCTION [PDF]

, 2009
Sintesis karotenoid alami belum pernah melebihi produk sintetik pada skala komersial. Kurangnya pemahaman mengenai aspek mikrobiologis dan ekofisiologis isolat penghasil karotenoid seringkali menyebabkan terjadinya kesalahan penamaan spesies.
