  • Title: [Annual production of bacterioplankton in the deep sea area of Southern Baikal].
    Author: Maksimova EA.
    Journal: Mikrobiologiia; 1976; 45(1):161-5. PubMed ID: 940490.
    Abstract:
    The time of generation of bacterioplankton in the pelagic zone of Baikal differs in various seasons of the year: the minimum time is in December (25 hours), the maximum time is in October of 1970 (580 hours) and in June of 1971 (560 hours). Monthly production of bacteria for a layer of 0 to 50 m varies from 0.07 g in January to 49 g of wet weight per 1 m2 in September. Annual production of bacterioplankton in a layer of 0 to 50 m is 118.5 g of wet weight per 1 m2 of the lake surface. The P/B coefficient of micro-organisms varies from 0.02 in January to 1.1 in December. The most favourable conditions for bacterial growth therefore are in April, July--September, and December. The annual P/B is 4.42.
