The cyanobacteria or blue-green algae (BGA) are the group of microorganisms having an
oxygen-evolving photosynthetic system. Many genera are aerobic nitrogen-fixers and some …

D was applied to a cove in Kentucky Lake which was highly infested with Myriophyllum
spicatum (Eurasian watermilfoil). Effects of 2, 4-D on nontarget algal communities were …

Cyanobacteria maintain soil fertility by performing N 2-fixation and act as a key biocatalyst in
nitrogen cycle. Chemical N-fertilizers and pesticides as agrochemicals are intensively being …

Cyanobacteria (blue-green algae) are widely distributed in tropical wet land rice fields
where they play important role in building soil fertility. Due to their ability to photosynthesize …

Cyanobacteria (blue-green algae) are morphologically the most diverse and complicated of
the prokaryotes. Classification of the cyanobacteria alongside the eubacteria in the kingdom …

The effects of the phenoxy acetic herbicides 2, 4-dichlorophenoxy acetic acid (2, 4D) and
methylchloro-phenoxy acetic acid (MCPA) on growth, photosynthesis, and nitrogenase …

Thiobencarb at 55 ppm and butachlor at 100 ppm markedly reduced dry biomass of
Anabaena, Nostoc and Oscillatoria. Reductions in N, chlorophyll a, dry biomass and …

Effect of commercial grade pesticide furadan (3% ai as carbofuran) was studied on the
survival, growth and nitrogen fixation of blue-green alga Nostoc muscorum. The lower …

MATERIALS AND METHODS A pure culture of the rice-field cyanobacterium Westiellopsis
prolifica Janet was used as the experimental organism. The cyanobacterium was grown in …
