Abstract

A comparative assessment of the pools of fungal and bacterial biomass in dark humus forest soil has been performed using luminescent microscopy and cascade filtration. Cascade filtration indicates that the bacterial biomass is compatible to the fungal biomass (31–54% for bacteria and 46–69% for fungi) in the upper horizons of investigated soil. However, in the lower horizons, the bacterial biomass predominates (up to 69% at the depth of 100 cm). Thus, the cascade filtration method has made it possible to refine data on the bacterial biomass in the soil and to show for the first time that the biomass of bacteria is compatible to the biomass of fungi in the upper soil horizons and exceeds fungal biomass in the lower horizons. This method provides for a more accurate assessment of both the number and the biomass of bacteria, which allows revising the opinion of many soil microbiologists on the significant prevalence of fungal biomass in soils.

黑暗腐殖质森林土壤中的真菌和细菌

摘要

使用荧光显微镜和级联过滤技术对暗腐殖质森林土壤中的真菌和细菌生物量库进行了比较评估。级联过滤表明，在被调查土壤的上部视野中，细菌生物量与真菌生物量兼容（细菌为31–54％，真菌为46–69％）。但是，在较低的视野中，细菌生物量占主导（在100 cm的深度处高达69％）。因此，级联过滤法使得有可能完善土壤中细菌生物量的数据，并首次表明细菌的生物量与上部土壤层中的真菌生物量相容，并超过了土壤中真菌生物量。较低的视野。这种方法可以更准确地评估细菌的数量和生物量，
