The Study of Enigmatic Microbial Communities microbes counted by direct light microscopic means could not be matched by plate count or other procedures meant to estimate numbers of viable cells. The direct-count method using fluorescent dye and the epifluorescent microscope has been modified many times since Daley and Hobbie’s (1975) work.
