Millimeter waves thermally alter the firing rate of the Lymnaea pacemaker neuron.
It was shown that the rate of temperature rise played an important role in the development of a transient neuronal response.
Heterogeneity of carotenoid content and composition in LH2 of the purple sulphur bacterium Allochromatium minutissimum grown under carotenoid-biosynthesis inhibition
It is shown that the LH2 can be assembled without any Cars, although the presence of Cars, however, is important for structural stability of LH2 complexes.
Bursting responses of Lymnea neurons to microwave radiation.
Mediator-induced, current activation of acetyl-choline, dopamine, serotonin, or gamma-aminobutyric-acid receptors of the neuronal soma was not altered during CW or PW exposures and, hence, could not have been responsible for the bursting effect.
Photoautotrophic hydrogen production by nitrogen-deprived Chlamydomonas reinhardtii cultures
Abstract In this study we have demonstrated the possibility of phototrophic hydrogen production in C. reinhardtii under N-deprived conditions. When tested under air + CO2, and Ar + CO2 N-deprived C.
Incorporation of spheroidene and spheroidenone into light-harvesting complexes from purple sulfur bacteria.
It was found that the electrophoretic mobility of the complexes with incorporated Cars did not change compared to that of the control and DPA-complexes, indicating the absence of any significant change in the structure of LH complexes upon DPA -treatment and subsequent incorporation of Cars.
Distribution of colored carotenoids between light-harvesting complexes in the process of recovering carotenoid biosynthesis in Ectothiorhodospira haloalkaliphila cells.
The process of colored Car incorporation into LH complexes during the recovery of Car biosynthesis in the DPA-cells of Ect.haloalkaliphila is discussed.
Singlet-triplet fission of carotenoid excitation in light-harvesting LH2 complexes of purple phototrophic bacteria
It is concluded that singlet-triplet fission of carotenoid excitation proceeds with participation of these excitonically coupled bacteriochlorophylls in LH2 complexes from purple phototrophic bacteria.
3-Acetyl-chlorophyll formation in light-harvesting complexes of purple bacteria by chemical oxidation
Oxidation of bacteriochlorophyll (BChl) with potassium ferricyanide in membranes and LH2 complexes (carotenoid-less and control samples) from the purple bacteria Allochromatium minutissimum and
Carotenoids are Probably Involved in Singlet Oxygen Generation in the Membranes of Purple Photosynthetic Bacteria under Light Irradiation
Abstract — The possibility of singlet oxygen generation in five species of photosynthetic bacteria under irradiation with light was studied using the Singlet Oxygen Sensor Green (SOSG) dye that, when
Embedding carotenoids of spheroidene-branch biosynthesis into antenna complexes of sulfur photosynthetic bacteria
The energy transfer efficiency from carotenoids to bacteriochlorophyll was shown to depend not only on the type of carotanoid but also on the very structure on the antenna complex.
