The genes somB and somA ( S ynechococcus o uter m embrane), lying in tandem organization in the genome of Synechococcus PCC 6301, encode two porins in the outer membrane of this unicellular cyanobacterium. Northern blot and primer extension experimen

Pore-forming protein (porin) was isolated from N,N-dimethyl-dodecylaminoxid (LDAO)-extracted outer membranes of Synechococcus PCC 6301 and purified by ion exchange chromatography on DEAE-Sephacel column. The apparent molecular mass on SDS-PAGE was de

Intracellular localization of triterpenic membrane stabilizers of the hopane series is described for the first time for a cyanobacterium. In Synechocystis PCC 6714, a bacteriohopanetetrol derivative (main compound) and diplopterol were detected in ce

Amino acid consumption was studied with batch and continuous chemostat cultures of Chloroflexus aurantiacus grown phototrophically in complex medium with casamino acids (Pierson and Castenholz 1974). Amino acids like Arg, Asx, Thr, Ala, Tyr, which we

Sheaths isolated from Gloeobacter violaceus were found to be composed of a major polysaccharide moiety (glucose, galactose, rhamnose, mannose, arabinose), a protein moiety, and negatively charged components (glucuronic acids, phosphate, sulfate). Out

Rhodobacter capsulatus strain 37b4 was grown phototrophically in chemostat cultures with 2 mM of ammonium chloride and 30 mM of malate at a constant dilution rate of 0.075 h-1. When illumination was raised from 3000 to 30000 lx, steady state biomass

Cells of the unicellular cyanobacterium Gloeothece sp. PCC 6909 are surrounded by an inner (enclosing 1-2 cells) and an outer (enclosing cell groups) sheath. Using conventional Epon-embedding in combination with ruthenium-red staining, the inner and

Cell walls free of cytoplasmic- and thylakoid membranes were isolated from Synechocystis PCC 6714 by sucrose density gradient centrifugation and extraction with Triton X-100. The Triton-insoluble cell wall fraction retained the multilayered fine stru
