Cyanobacteria blooms cannot be controlled by effective microorganisms (EM) from mud- or Bokashi-balls [PDF]

, 2002
In controlled experiments, the ability of ‘‘Effective Microorganisms (EM, in the form of mudballs or Bokashi-balls)’’ was tested for clearing waters from cyanobacteria.

Shaping Microbial Motion with Light: A Contactless Approach Using Diffusioosmotic Flow

Advanced Materials Interfaces, EarlyView.
Light‐controlled, contactless manipulation of cyanobacteria using photoresponsive azobenzene surfactants. Reversible photo‐isomerization generates surface flow, enabling precise trapping, relocation, and directional control of single cells or ensembles with adjustable light intensity and wavelength for noninvasive, spatiotemporally resolved microbial ...

Polyphasic Characterization and Taxonomic Evaluation of a Bloom-Forming Strain Morphologically Resembling Radiocystis fernandoi (Chroococcales, Cyanobacteria) from Lake Erhai, China

Diversity, 2022
Microcystis-dominated blooms cause environmental and ecological impacts worldwide. However, it is sometimes challenging to correctly identify Microcystis and its related genera.

Filtering efficiency and feeding mechanisms of Daphnia pulex on Microcystis aeruginosa and Nannochloropsis [PDF]

, 2012
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria ...

The Complicated and Confusing Ecology ofMicrocystisBlooms

mBio, 2020
Blooms of the toxin-producing cyanobacteriumMicrocystisare increasing globally, leading to the loss of ecosystem services, threats to human health, as well as the deaths of pets and husbandry animals. While nutrient availability is a well-known driver of algal biomass, the factors controlling “who” is present in fresh waters are more complicated ...

Development of Chitosan/PVA Nanofibrous Membranes for Efficient Removal of Microcystis aeruginosa

Journal of Applied Polymer Science, EarlyView.
Removal of Microcystis aeruginosa from CS/PVA fibers by A‐HSBS. ABSTRACT In this study, chitosan/poly(vinyl alcohol) (CS/PVA) polymeric nanofibers were produced using the Air‐Heated Solution Blow Spinning (A‐HSBS) method and applied for the efficient removal of Microcystis aeruginosa from contaminated water.

The allelopathic algicides sanguinarine and berberine reduced the dominance of Microcystis in competition with Chlorella

Results in Engineering, 2022
Gramine, sanguinarine and berberine are potential algicides that can significantly inhibit the growth of cyanobacteria. Their effects on other phytoplankton have to be considered, because other phytoplankton species and cyanobacteria usually co-exist. In

Amazonian Cyanobacteria as a Source of Bioactive Compounds With Antimicrobial and Cytotoxic Properties

Chemistry &Biodiversity, EarlyView.
ABSTRACT Cyanobacteria are photosynthetic microorganisms known for producing diverse bioactive compounds. This study explores the bioactivity of extracts and fractions from Amazonian cyanobacteria and their pigment and phenolic compound production. A fraction from Synechococcus sp. CACIAM 05 showed cytotoxicity against hCMEC/D3 and MG‐63 cells.

Growth and photosynthesis responses of microcystin (MC)- and non-MC-producing Microcystis strains during co-culture with the submerged macrophyte Myriophyllum spicatum

Water Science and Technology, 2022
The growth and photosynthetic responses of microcystin (MC)- and non-MC-producing Microcystis to the submerged macrophyte Myriophyllum spicatum were investigated under plant-Microcystis co-culture conditions (PMC + , PMC−), in comparison with their ...

Insights Into the Distribution of Two Bloom‐Forming Dinoflagellates of Phytosanitary Concern Using Regional and Global Temperature Data

International Review of Hydrobiology, EarlyView.
ABSTRACT Large bloom‐forming dinoflagellates can alter aquatic biodiversity and impact human use, posing conservation challenges. We used the maximum entropy (MaxEnt) model to predict the potential distribution of two Ceratium congeners, C. hirundinella and C.
