An attempt has been made to explore different types of algae from Panikhaiti area of Guwahati, Assam using Winogradsky column. In order to prepare Winogradsy column, soil and water samples were collected from different locations. A transparent, clear plastic bottle was taken and filled with 500g of soil and over layered with 500ml of water sample. The columns were enriched with different carbon and nitrogen supplements. They were covered with plastic sheets and few holes were punctured on them. These were incubated at room temperature (±28°C) in presence of sunlight. One column was kept covered with dark paper and kept in dark as control. Observations were made weekly, for development of algal growth and microbial communities over a period of 12 months. A gradual change in colour of column and also on the water layer was observed over the course of incubation period. The columns started showing stratified micro ecosystems with an oxic top layer and anoxic sub-surface layers. Algal growth prominently appeared in all the columns. The algal specimens belonged to 18 genera which included members of class Cyanophyceae, Zygnematophyceae, Ulvophyceae, Chlorophyceae, Bacillariophyceae and Euglenoidea.
