Growth Characteristics of an Estuarine Heterocystous Cyanobacterium [PDF]
Frontiers in Microbiology, 2017 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.

Isolation of axenic cyanobacterium and the promoting effect of associated bacterium on axenic cyanobacterium [PDF]
BMC Biotechnology, 2020 Abstract In order to avoid the influence of associated bacteria on the target cyanobacteria for physiological and molecular studies, a traditional and reliable method based on solid-liquid alternate cultivation is carried out to purify the non-axenic cyanobacterium Microcystis aeruginosa FACHB-905.

Deep Proteogenomics of a Photosynthetic Cyanobacterium
Journal of Proteome Research, 2023 Cyanobacteria, the evolutionary ancestors of plant chloroplasts, contribute substantially to the Earth's biogeochemical cycles and are of great interest for a sustainable economy. Knowledge of protein expression is the key to understanding cyanobacterial metabolism; however, proteome studies in cyanobacteria are limited and cover only a fraction of the

Transformation of a filamentous cyanobacterium by electroporation [PDF]
Journal of Bacteriology, 1989 The filamentous cyanobacterium Anabaena sp. strain M131 was transformed with the shuttle vector pRL6 by electroporation. Optimum conditions for electroporation required relatively high field strengths with short time constants. Restriction significantly lowered the efficiency of transformation. A plasmid containing a single unmodified AvaII restriction

How a cyanobacterium tells time [PDF]
Current Opinion in Microbiology, 2008 The cyanobacterium Synechococcus elongatus builds a circadian clock on an oscillator composed of three proteins, KaiA, KaiB, and KaiC, which can recapitulate a circadian rhythm of KaiC phosphorylation in vitro. The molecular structures of all three proteins are known, and the phosphorylation steps of KaiC, the interaction dynamics among the three Kai ...

Maintenance of heterocyst patterning in a filamentous cyanobacterium [PDF]
Journal of Biological Dynamics, 2010 In the absence of sufficient combined nitrogen, some filamentous cyanobacteria differentiate nitrogen-fixing heterocysts at approximately every 10th cell position. As cells between heterocysts grow and divide, this initial pattern is maintained by the differentiation of a single cell approximately midway between existing heterocysts.

The quantitative proteome atlas of a model cyanobacterium
Journal of Genetics and Genomics, 2022 Cyanobacteria are a group of oxygenic photosynthetic bacteria with great potentials in biotechnological applications and advantages as models for photosynthesis research. The subcellular localizations of the majority of proteins in any cyanobacteria remain undetermined, representing a major challenge in using cyanobacteria for both basic and industrial

Locations of membrane protein production in a cyanobacterium
Journal of Bacteriology, 2023 ABSTRACT Cyanobacteria show an unusually complex prokaryotic cell structure including a distinct intracytoplasmic membrane system, the thylakoid membranes that are the site of the photosynthetic light reactions. The thylakoid and plasma membranes have sharply distinct proteomes, but the mechanisms that target proteins to a ...

Molecules, 2006 A novel biosurfactant, 2-acyloxyethylphosphonate, was isolated from waterblooms of Aphanizomenon flos-aquae. Its structure was elucidated by chemical degradation and HRFABMS, GC/EI-MS and 1D- and 2D-NMR spectral analyses.
