内容記述 |
The abundance and production rate of bacterioplankton in the Antarctic were measured in order to clarify their role in the food web. The production rate was estimated from the incorporation rate of [methyl-^3H] thymidine into TCA (trichloroacetic acid) insoluble fraction. In summer, the production in the upper layer ranged 0.45-5.2×(10)^7 cells/l/day, which correspond to e. g., 0.068-0.79μgC/l/day. The apparent doubling time of bacterial population was an order of a few days, which was equal to that observed in an equatorial area. Both abundance and production rate decreased with depth. The isotope dilution method to clarify the size of intracellular dTTP (deoxythymidine triphosphate) pool did not give meaningful data. The present results indicate that the abundance and production rate of bacterioplankton in the Antarctic were as high as those in an equatorial or temperate zone. |
