    Notes: Abstract From a bloom forming blue-green alga, Anabaenopsis raciborskii, spontaneous mutants, which had lost the ability to form gas vacuoles have been isolated; the mutant frequency was 4.8×10-3. The filaments of gas vacuole-less mutants settled at the bottom of flasks in liquid culture media unlike the parent alga. The growth and nitrogen fixation were comparatively poor in the mutants.

    Notes: Abstract The adsorption rate of the cyanovirus N-1 infecting the nitrogen-fixing blue-green alga Nostoc muscorum decreased with aging of algal cultures and the virus failed to adsorb to the dead host cells. The adsorption rate declined in saline magnesium chloride solution compared to that in algal growth medium. The addition of amino acids like L-tryptophan and L-phenylalanine failed to enhance the adsorption rate of the virus. Optimal pH of adsorption was 7.6 to 8.1.
