ELECTRON MICROSCOPICAL OBSERVATION ON THE ULTRASTRUCTURE OF SOME MARINE LUMINOUS BACTERIA

Eight strains of marine luminous bacteria were isolatad from the sea water and the sea floor of the East China Sea(E.124°-129°,N.26°30'-30°00').These strains together with a subculture that lost the luminesecence (7032-)were examinedwith electron microscopy.The bacteria of strains 7032,7032- and 1025 all possessed polar flagella,tuft flagella and peritrichous flagella.Strain 7032-was simillar to 7032 in cellular and flagella fine structure.In preparations negatively stained with phosphotungstic acid the flagella could sometimes be seen to be differentiated into a core and a sheath.Sometime the sheath was disincegratad,while the central core remained intact.A network structure of flagella subunits could be seen in strain 128.The bacteria of all other strains possessed polar or peritrichous flagella.
