Description |
The quantitative distribution and biochemical activity of heterotrophic bacteria capable of multiplying in organic media of pertinacious composition from, shelf and slope waters off Madras coast between 1 lo 30' N and 14" 30' N were studied during March, 1986. The percentage of samples yielding more than 100 X 105 / ml colonies was only 12 in number in depth range 0-10 metres. Pigmented bacteria was encountered more in this depth range. Faecal coliform bacteria was not encountered throughout the observations. Total bacterial count varied from 8.6 X 105 to 3.08 X lo7/ ml in spread plate method of isolation. Pseudomonas, Vibrio, Alcaligenes, Flacvobacterium, Cytophaga, Agarobacterium and Chromobacterium formed the predominant flora isolated. Their correlation with environmental parameters like temperature, salinity, oxygen and pI 1 are discussed. The cultures were more proteolytic than amylolytic which indicated the process of organic decomposition and vigorous liberation of plant nutrients in these latitudes. |
