BIODIVERSITY OF MICROBES IN MUTHUPET MANGROVE ENVIRONS

摘要

The diversity and load of Microorganisms, cyanobacteria, bacteria and fungi associated with the Muthupet mangrove water, Tamil Nadu were determined by using the standard method from Oct- 2006 to Sep. 2007. One year study revealed that 12 species of bacteria, 18 fungi and 24 species of cyanobacteria were observed from the water stream. Among bacteria, Psendomonas, Aeromonas and Vibrio with two species and others with single each were recorded. Aspergillus was dominant (6 species) among the fungi followed by Penicillium with three. Cyanobacteria were a dominant group, recorded 24 species. Spirulina and Lyngbya with each two species were the dominant genus and other with single one each. More hardness and alkalinity with sufficient amount of oxidizable organic matter, limited dissolved oxygen content and alkaline pH were probably the factors favouring the growth of microbes especially cyanobacteria.
