Abstract


Shrimps ponds are suitable for the growth and development of purple non sulfur bacteria (PNSB) as there is excess accumulation of nutrients in the shrimp pond bottom due to feed, detritus and the excreta from the shrimps, leads to the establishment of PNSB members in shrimp ponds. Hence the present study focuses its attention on the diversity of PNSB from shrimp ponds (brackish) from the Nagai Coastal Region, South east coast of India, as no earlier reports exists  on PNSB diversity in the Nagai coastal area, this systematic survey gives a clear picture of existing PNSB Diversity.


Keywords


PNSB, Alpha- proteobacteria, Pfennig‟s medium, shrimp ponds.
