Spatio‐Temporal Resolution of Microbial Functions and Taxa Associated With Cyanobacterial Harmful Algae Blooms Along a 500‐Km Aquatic Continuum in the Lake Erie Watershed

Environmental Microbiology, Volume 27, Issue 10, October 2025.
The aquatic microbiome can influence cyanobacterial harmful algal blooms. Abundances of genes and transcripts for phosphorus acquisition, denitrification and nitrogen fixation were higher upstream, whereas in Lake Erie genes and transcripts for microcystin production were higher.

Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

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 ...

Stronger dispersal potential of alkaline phosphatase‐encoding bacteria ensures higher organic phosphorus mineralization rate

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.

Effects of Changing Snow and Ice Cover Conditions on Phytoplankton Chlorophyll‐a and Community Composition in a Mesotrophic Lake

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.

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 ...

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.

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 ...
