Functional Ecology, Volume 39, Issue 3, Page 756-769, March 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Scientific theory largely neglects linkage between organic phosphorus (Po) mineralization rate and dispersal potential of alkaline phosphatase‐encoding bacteria (PEB) containing the phoD gene. Different densities of substrates (i.e.

The Bacillus cereus GerN and GerT protein homologs have distinct roles in spore germination and outgrowth, respectively [PDF]
, 2008 The GerT protein of Bacillus cereus shares 74% amino acid identity with its homolog GerN. The latter is a Na+/H+-K+ 19 antiporter that is required for normal spore germination in inosine.

Journal of General and Applied Microbiology, 2019 The clonal strains, phycoerythrin(PE)-rich- and PE-poor strains, of the unicellular, fresh water cyanobacterium Aphanothece sacrum (Suringar) Okada (Suizenji Nori, in Japanese) were isolated from traditional open-air aquafarms in Japan. A.

Freshwater Biology, Volume 70, Issue 3, March 2025.ABSTRACT Ice and snow cover on lakes plays a fundamental role for under‐ice ecology by reducing water column mixing and light availability. Previous studies have shown that such reductions can significantly influence the growth and reproduction of phytoplankton, primarily focusing on changes in ice‐on and ice‐off dates in a warming climate.

Gliding motility in Aphanothece halophytica: analysis of wall proteins in mot mutants [PDF]
Journal of Bacteriology, 1981 The unicellular cyanobacterium Aphanothece halophytica (PCC 7418) is motile, and spontaneous nonmotile (mot) mutants accumulate when the organism is subcultured. Analysis of mot mutants suggests that a glycoprotein in the cell wall is involved in the motility mechanism.

Nutrient inputs in mesocosms of an oligotrophic lake fail to sustain an algal bloom
Ecosphere, Volume 16, Issue 2, February 2025.Abstract Harmful algal blooms (HABs) rapidly change and threaten aquatic ecosystems. HABs in oligotrophic lakes are becoming more commonly observed, despite the long‐held paradigm that algal blooms cannot happen in low‐nutrient systems. This raises the question of whether nutrient loading, understood as a major driver of HABs, plays an important role ...

Unicellular mucilaginous blue-green algae (BGA) : impressive blooms but deceptive biofertilizers [PDF]
, 1985 Les Cyanophycées produisant des colonies mucilagineuses peuvent développer des fleurs d'eau volumineuses dans les rizières. En raison d'une teneur en eau et en cendres élevées l'apport d'azote est faible et n'a pas d'effet notable sur le rendement du riz.

Adaptive Responses of Cyanobacteria to Phosphate Limitation: A Focus on Marine Diazotrophs
Environmental Microbiology, Volume 26, Issue 12, December 2024.Marine diazotrophic cyanobacteria, which are essential for atmospheric nitrogen fixation in low‐nutrient oceans, have developed various strategies to survive under phosphate (Pi) limitation by using high‐affinity transporters and enzymes that break down dissolved organic phosphorus (DOP).
