Microbial society and its activity in the soil.
In this study, with the help of the buried slide method, a qualitative observation of the microsociological association in the soil was assessed. Fungal mycelium cohabiting with bacterial forms, rods as well as cocci, individual colonies of Azotobacter-type cells, and certain algae of Hantzschia species were recorded in a central European typical garden soil. The use of CHOLODNY-STRUGGER combination method was helpful in ascertaining the decaying nature of a soil nematode and also fungal mycelium which, during the process of decomposition, served there as a substrate for bacterial multiplication. Colony of Clostridium-type rod-shaped bacteria existed between the soil particles, acting as living bridges. When examined under fluorescent microscope, the bacterial forms emitted shining fluorescence of green colour which in effect presented them as lighted objects, prominent against the dull red background of soil objects and other decaying substances.
