Insights on Anabaena sp. PCC 7120 Responses to HCH Isomers: Tolerance, Degradation, and Dynamics on Potential lin Genes Expression [PDF]

MicrobiologyOpen
Hexachlorocyclohexane (HCH) was extensively used as a pesticide until the 1990s. It was synthesized by benzene photochlorination, resulting in a mixture of stereoisomers, which included α‐, β‐, γ‐, and δ‐HCH, among others.

Interactions of PatA with the Divisome during Heterocyst Differentiation in Anabaena

mSphere, 2020
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric N2 and provide the vegetative ...

Phylogenomic Analysis of Secondary Metabolism in the Toxic Cyanobacterial Genera Anabaena, Dolichospermum and Aphanizomenon

Toxins, 2020
Cyanobacteria produce an array of toxins that pose serious health risks to humans and animals. The closely related diazotrophic genera, Anabaena, Dolichospermum and Aphanizomenon, frequently form poisonous blooms in lakes and brackish waters around the ...

Biodegradation of polychlorinated biphenyls (PCBs) by the novel identified cyanobacterium Anabaena PD-1.

PLoS ONE, 2015
Polychlorinated biphenyls (PCBs), a class of hazardous pollutants, are difficult to dissipate in the natural environment. In this study, a cyanobacterial strain Anabaena PD-1 showed good resistance against PCB congeners.

Distinct cell division features in Anabaena, a multicellular cyanobacterium [PDF]

Journal of Bacteriology
Filamentous cyanobacteria such as Anabaena display a distinct multicellular organization in the bacterial kingdom. In the filament, the cells share a common periplasm and continuous peptidoglycan sacculus and outer membrane.

Amino Acid Transporters and Release of Hydrophobic Amino Acids in the Heterocyst-Forming Cyanobacterium Anabaena sp. Strain PCC 7120

Life, 2015
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can use inorganic compounds such as nitrate or ammonium as nitrogen sources. In the absence of combined nitrogen, it can fix N2 in differentiated cells called heterocysts.

Regulation of iron-siderophore uptake in a diazotrophic cyanobacterium Anabaena anabaena 7120

The Indian Journal of Agricultural Sciences, 2014
The regulation of 55Fe-siderophore uptake of was studied in a diazotrophic cyanobacterium Anabaena 7120. The uptake up to 20 min was found to be biphasic, a rapid first and steady second phase.

Detection of Anatoxin-a and Three Analogs in Anabaena spp. Cultures: New Fluorescence Polarization Assay and Toxin Profile by LC-MS/MS

Toxins, 2014
Anatoxin-a (ATX) is a potent neurotoxin produced by several species of Anabaena spp. Cyanobacteria blooms around the world have been increasing in recent years; therefore, it is urgent to develop sensitive techniques that unequivocally confirm the ...
