Heterocyst Thylakoid Bioenergetics [PDF]
Heterocysts are specialized cells that differentiate in the filaments of heterocystous cyanobacteria. Their role is to maintain a microoxic environment for the nitrogenase enzyme during diazotrophic growth.

Metalloproteins in the Biology of Heterocysts [PDF]
Cyanobacteria are photoautotrophic microorganisms present in almost all ecologically niches on Earth. They exist as single-cell or filamentous forms and the latter often contain specialized cells for N2 fixation known as heterocysts.

Growth Characteristics of an Estuarine Heterocystous Cyanobacterium [PDF]
A new estuarine filamentous heterocystous cyanobacterium was isolated from intertidal sediment of the Lagoa dos Patos estuary (Brazil). The isolate may represent a new genus related to Cylindrospermopsis.

Heterocyst glycolipids and SWT reconstruction of sediment cores 9R and 10R at site PS104_20-2
Thirty-four axenic strains of cyanobacteria were analysed for their glycolipid content using high performance liquid chromatography coupled to electrospray ionisation tandem mass spectrometry (HPLC/ESI-MS(2)). Species of the families Nostocaceae and Rivulariaceae, capable of biosynthesising heterocysts, contained a suite of glycolipids consisting of ...

Cyanobacterial Heterocysts [PDF]
Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a regulated developmental pattern of single heterocysts separated by about 10 to 20 photosynthetic vegetative cells is maintained along filaments.

The effect of continuous illumination and photoperiods on growth and heterocyst frequency of cyanobacterium Fischerella ambigua from Golestan province [PDF]
The effect of limited continuous irradiance and photoperiods on survival, growth and heterocyst frequencies of cyanobacterium Fischerella ambigua collected from paddy-fields of Golestan province have been studied at laboratory condition.

Design and characterization of a synthetic minimal promoter for heterocyst-specific expression in filamentous cyanobacteria. [PDF]
Short and well defined promoters are essential for advancing cyanobacterial biotechnology. The heterocyst of Nostoc sp. is suggested as a microbial cell factory for oxygen sensitive catalysts, such as hydrogenases for hydrogen production, due to its ...

The heterocysts present in filamentous cyanobacteria such as Anabaena sp. PCC 7120 are known to be regulated by HetN and PatS, the repressors of heterocyst differentiation; therefore, the inactivation of these proteins will result in the formation of ...

Relationships between the ABC-exporter HetC and peptides that regulate the spatiotemporal pattern of heterocyst distribution in Anabaena. [PDF]
In the model cyanobacterium Anabaena sp. PCC 7120, cells called heterocysts that are specialized in the fixation of atmospheric nitrogen differentiate from vegetative cells of the filament in the absence of combined nitrogen.
