Abstract:
The microalgal community as primary producers has to play a significant role in the biotic
and abitoic interactions of any aquatic ecosystem. Whenever a community is exposed to a pollutant,
responses can occur because individuals acclimate to pollutant caused changes and selection can
occur favouring resistant genotypes within a population and selection among species can result in
changes in community structure. The microalgal community of industrial effluent treatment systems
are continuously exposed to pollutants and there is little data available on the structure and seasonal
variation of microalgal community of industrial effluent holding ponds, especially of a complex
effluent like that of refinery. The aim of the present study was to investigate the annual variation in
the ecology, biomass, productivity and community structure of the algal community of a refinery
effluent holding pond. The results of the study showed the pond to be a eutrophic system with a
resistant microalgal community with distinct seasonal variation in species composition
