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.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Control of Microcystis aeruginosa with Galla chinensis [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2015
Galla chinensis (nutgall), used in traditional Chinese medicine, is a product extracted from nutgall trees in Chinese forests. In this study, Microcystis aeruginosa, a cyanobacterium, was exposed to different concentrations of nutgall extract obtained from Galla chinensis.

Sustainable control of Microcystis aeruginosa, a harmful cyanobacterium, using Selaginella tamariscina extracts

Ecotoxicology and Environmental Safety
Eco-friendly reagents derived from plants represent a promising strategy to mitigate the occurrence of toxic cyanobacterial blooms. The use of an amentoflavone-containing Selaginella tamariscina extract (STE) markedly decreased the number of Microcystis ...
