Though the single carbon utilizing bacterial system, Methylotrophs are rich source of biological compounds and good source of bio-remeidation, their diversity in river system have not paid much attention. In this study, the population of methylotrophs in two main water ways, river Coovum and river Adyar of Chennai, fourth cosmopolitan city, of India was carried out. The samples were collected for 12 months from four different sites every fortnight and grouped into four seasons. The sampling sites are either ecologically sensitive or severely affected by contamination. The methylotrophic densities were found high in river Cooum 5.9 to 6.7 Log CFU mL-1 than Adyar river 5.5 to 5.9 Log CFU mL-1 and also fluctuated significantly over time which showed a clear seasonal variation. The bacterial count also varied depending upon the nature of site of sample collection with gradual decrease from upstream to downstream. Cluster analysis (similarity) based on the average values of methylotrophic counts explained the site-wise and month-wise relationship individually.
