Tolypothrix tenuis

Fig. 8. Difference spectrum (green irradiated minus red irradiated) of phycochrome c (solid line), action spectrum for induction of filamentous growth of Nostoc muscorum (dotted line), and action spectrum for inhibition of C-phycoerythrin synthesis in Tolypothrix tenuis (dashed-dotted line). Abscissa wavelength in nm Ordinates relative absorbance change und relative action (after Bjorn and Bjorn 5))...

EPTC, a thiocarbamate, inhibited the growth of Tolypothrix tenuis at 0.1 ppm (Ibrahim 1972) and stimulated the growth of Chlorella pyrenoidosa and Hormidium nitens at 0.08 ppm (Platonova 1967), but had no effect on any of the algae used by Cullimore (1975) at ten ppm. At this concentration, molinate was observed to inhibit the growth of the blue-green alga Tolypothrix tenuis (Ibrahim 1972).

Distribution of specific fatty acids between the C-1 and C-2 positions of the sn-glycerol moiety has been studied in strains in the first and second groups. In the filamentous cyanobacteria such as A. variabilis (Sato et al., 1979), Anabaena oylindriaa, Oscillatoria ohalybea, Nostoo aalaiaola and Tolypothrix tenuis (Zepke et al., 1978), which contain approximately the same amounts of and acids, the acids are esterified to the C-1 position, and the C acids to the C-2 position...
