Abstract
In this study, the composition of microfouling bacteria and the
chemical components of conditioning biofilm was examined on artificially
immersed cement panels exposed to three different habitats viz. Korattur
lake (freshwater), Muttukadu backwaters (brackish) and Chennai port (marine)
Tamil Nadu, India. Test panels were deployed in the surface waters at the depth
of 1m in three study sites. Microfouling material which formed in these panels
were analysed for microfouling bacteria using various morphological and
biochemical parameters. Additionally, hydrographical parameters at three study
sites were assessed. Culture-based method was used in the quantification of
bacterial species formed on the surface of the cement panel. A total of 7
biofilm forming bacteria was recorded on the cemented panels immersed in
Korattur lake (Freshwater), 9 biofilm forming bacterial species in Chennai Port
(Marine) and 12 biofilm forming bacteria and 3 non-biofilm bacteria were
observed in Muttukadu backwaters (Brackish). The result highlights that
bacterial communities were more heterogeneous in Muttukadu backwaters and
conversely, community composition in Korattur lake and Chennai port was less
heterogeneous. This paper will give an insight on how microorganisms like
bacteria spatially distributed in contrasting environments with reference to
fouling.
