Vertical distribution and bacterial cell size and biomass in Lake Vanda, an Antarctic lake
Vertical distribution of bacteria in Lake Vanda in the Dry Valleys region of the Antarctic was examined by the acridine orange direct count (AODC) method in December 1984 and the results were compared with those of January 1984 (S. TAKII et al. : Hydrobiologia, 135,15,1986). Bacterial numbers, cell...
